The American Society of Clinical Oncology (ASCO) is aware that people with cancer and cancer survivors, particularly those with compromised immune systems, are likely worried about the potential impact of COVID-19 on their health. Patients should talk with their oncologists and health care teams to discuss their options to protect themselves from infection.

What do I need to know about COVID-19 vaccines?

There are several COVID-19 vaccines that are now in use in different parts of the world. In the United States, the first 2 COVID-19 vaccines to receive emergency use authorization were the Pfizer BioNTech COVID-19 vaccine and the Moderna COVID-19 vaccine. The third vaccine to receive emergency authorization was the Janssen vaccine, which is made by Johnson & Johnson. While these are not official U.S. Food and Drug Administration (FDA) approvals, the authorization does allow use of these vaccines in the United States. Globally, other vaccines are available or are in process of receiving Emergency Use Listing by the World Health Organization (WHO).

In the United States, the Pfizer BioNTech vaccine is for use in people 12 years of age or older and is administered in 2 doses, 3 weeks apart. The Moderna vaccine is for use in people 18 years of age or older and is administered in 2 doses, 1 month apart. The Janssen vaccine is a single-dose vaccine and is for individuals 18 and older. The dosing schedule where you live may be different.

The most common expected side effects of the Pfizer BioNTech and Moderna vaccines include pain at the injection site, tiredness, muscle pain, headache, chills, joint pain, and fever. Side effects should be expected, and these side effects will go away within 3 days. Side effects are sometimes worse with the second dose, but again, these side effects should go away within 3 days. If you still have side effects more than 3 days after your vaccine dose, let your doctor know.

One rare side effect of COVID-19 vaccination is swelling of the lymph nodes in the armpit, which could be mistaken as a sign of breast cancer. Because of this unusual side effect, delay your mammogram for at least 1 month after receiving the COVID-19 vaccine.

The most common side effects of the Janssen vaccine were pain at the injection site, headache, fatigue, muscle aches, and nausea. Most of these side effects were mild to moderate in severity and lasted 1 to 2 days.

Because these 3 COVID-19 vaccines are available under emergency use authorization and are not fully approved by the FDA, any data on unexpected side effects are collected and monitored. When something uncommon happens, this information is reported to the FDA and U.S. Centers for Disease Control and Prevention (CDC) so that further investigations may be performed. For example, 6 people (out of more than 6.8 million people) who received the Janssen vaccine were reported to have a rare type of blood clot. Because of this, the Janssen vaccine administration was briefly paused so that these cases could be reviewed and the relationship to the vaccine could be determined. This does not mean that the vaccine is dangerous. Pauses like this are an important and expected safety mechanism in the development of any new medications or vaccines.

For COVID-19 vaccines that are 2-dose vaccines, both doses are recommended to ensure full vaccination. Also, if you receive the Pfizer vaccine for the first dose, you should also receive the Pfizer vaccine for the second dose. If you receive the Moderna vaccine for the first dose, you should also receive the Moderna vaccine for the second dose. Mixing doses from the Moderna and Pfizer vaccines is not recommended.

The available COVID-19 vaccines are believed to be effective against most variants of the virus, including the Delta variant. However, variants may still cause illness in some people who are vaccinated.

The CDC initially recommended that vaccines first be distributed to health care workers and long-term care facility (i.e., nursing home) residents. Vaccine eligibility has expanded and there are plenty of vaccine doses available in the United States. You can find COVID-19 vaccines near you by searching, checking with major retail pharmacies, or calling 1-800-232-0233.

The COVID-19 vaccine studies included people with medical conditions such as chronic lung disease, diabetes, and obesity, but they did not include people with cancer or those receiving cancer treatment. This means that the efficacy of the vaccine in people with cancer or those undergoing cancer treatment is unknown at this time.

Despite the lack of information on the safety of COVID-19 vaccines in people with cancer, many vaccinations are recommended for people with cancer, including the pneumococcal pneumonia vaccine and the flu vaccine. Some vaccines are OK to receive during cancer treatment, when the immune system is weak, but some vaccines, such as live virus vaccines, should not be given during cancer treatment. The COVID-19 vaccine is not a live virus vaccine.

Experts agree that the COVID-19 vaccine is recommended for people with cancer, cancer survivors, and those currently on cancer treatment, including chemotherapy and immunotherapy. The only people who should not be offered the vaccine are those who may have a harmful reaction, such as anaphylaxis, to a specific vaccine component. Talk with your doctor or your cancer care team about whether a COVID-19 vaccine is recommended for you, based on your own medical history. Your doctor will also have more information, over time, about when a vaccine is available for you. Read an FAQ about the COVID-19 vaccine and how it relates to people with cancer. (This link takes you to a different ASCO website.)

Vaccine distribution varies from country to country. Check your local or national health department to learn more about how vaccines are being distributed in your area. It is not yet known whether a booster dose of the vaccine may be useful, especially in people with compromised immune systems. These issues are being studied and more information will be available over time. 

Once you have been fully vaccinated, the CDC recommends that you can resume activities that you did before the pandemic, without wearing a mask or physically distancing. In most cases, individuals are not fully vaccinated against COVID-19 until 2 weeks after their final dose of the vaccine. However, in some areas, you may still be required to wear a mask and keep physically distant, such as in hospitals or clinics, public transportation, and others. Also, some local, state, or federal laws may still require these precautions. Be sure to see what precautions will still be required in your area by checking with your local government.

No vaccine is 100% effective, and sometimes, vaccinated people can still get COVID-19, which is called a “breakthrough infection.” The risk of this is very low, and vaccinated people are unlikely to become very ill. If you have cancer or are receiving cancer treatment, you may feel more protected if you continue wearing a mask when you are in public. Check with your doctor for specific guidance if you feel you are at higher risk for complications from COVID-19.

The virus will remain in the community until the majority of residents are vaccinated, so these precautions are critical to preventing continued spread of the virus.

What is COVID-19?

COVID-19, or coronavirus disease 2019, is an illness caused by a novel (or new) coronavirus that was first identified in an outbreak in Wuhan, China, in December 2019. 

Coronaviruses are a large family of viruses that can cause mild illnesses, such as the common cold, to more severe diseases, such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). Because the novel coronavirus is related to the SARS-associated coronavirus (SARS-CoV), the virus has been named SARS-CoV-2. The exact source of SARS-CoV-2, which causes COVID-19, is not certain but likely originated in bats.

The virus can spread from person to person, through small droplets from the nose or mouth that are produced when a person coughs or sneezes. Another person may catch COVID-19 by breathing in these droplets or by touching a surface that the droplets have landed on and then touching their eyes, nose, or mouth. The virus spreads through close contact, but it can also be spread by airborne transmission. In an enclosed space, virus particles can remain in the air for minutes to hours and can infect people at distances of more than 6 feet (2 meters).

Symptoms from COVID-19 can be mild to severe and may appear between 2 and 14 days after exposure to the virus. The symptoms may include fever, cough, shortness of breath, chills, headaches, sore throat, and new loss of taste or smell. Other symptoms may include aches and pains, fatigue, nasal congestion or runny nose, or diarrhea. In some people, the illness may cause severe pneumonia and heart problems, and it may lead to death. Other people who are infected may not develop any symptoms.

COVID-19 can occur in both children and adults. Symptoms in children seem to be milder than symptoms in adults. Children with COVID-19 may be at risk for a multisystem inflammatory syndrome, with symptoms such as rash, fever, abdominal pain, vomiting, and diarrhea. Initial reports indicated that children and young adults were not as affected by COVID-19. However, people of all ages, including infants, can die from this disease. In addition, deaths seem to occur disproportionately in diverse populations, including Black and Hispanic populations.

An analysis of 928 people with cancer and COVID-19 presented during the ASCO20 Virtual Scientific Program revealed that having active, progressing cancer was associated with a 5 times higher risk of dying within 30 days compared with patients who were in remission from cancer.

Viruses commonly change over time through mutation, and several variants of the SARS-CoV-2 virus have been identified. For example, a new variant of the virus was identified in September 2020 in the United Kingdom and is now in many countries, including the United States. This virus variant spreads more easily from person to person, but it is not believed to be more deadly.

What can I do to avoid getting COVID-19?

Although 3 vaccines have received emergency use authorization from the FDA, there are still no vaccines that have received formal FDA approval. Clinical trials to test the effectiveness of COVID-19 vaccines are still ongoing, and participation in these trials remains important. These trials will give scientists valuable information that can help patients and the general public in the long run. If you would like to participate in a COVID-19 vaccine clinical trial, has a full listing of available studies.

The most important way to protect yourself is to be vaccinated against COVID-19. If you are not vaccinated, stay at home as much as possible and avoid areas where people gather. Follow guidance on travel restrictions issued by the CDC or the World Health Organization (WHO).

Another critical way to protect yourself is to wash your hands often with soap and water for at least 20 seconds, about the amount of time it would take to hum the Happy Birthday song from beginning to end twice. If soap and water is not available, use hand sanitizer that contains at least 60% alcohol. 

In addition to washing your hands frequently, it’s important to:

  • Avoid touching your eyes, nose, and mouth.

  • If you must cough or sneeze, use a tissue. Then throw the tissue away. Or, cough or sneeze into your elbow rather than your hand.

  • Avoid close contact with people who are sick.

  • Regularly clean frequently touched objects and surfaces.

  • If there has been a known COVID-19 exposure, then cleaning with disinfectant wipes or spray is important.

If you are not vaccinated against COVID-19 and are in public, it is important to wear a mask or cloth face covering that covers the nose and mouth. This can help prevent the spread of COVID-19 in the community, especially because some people with COVID-19 have no symptoms and don’t know they have the virus, or they may not have yet developed symptoms. You should not wear masks with exhalation valves or vents because the vents allow your own respiratory droplets to leave the mask and can put others at risk. Double masking, such as wearing a cloth mask or nylon face covering over a surgical mask, is more effective at limiting transmission of the virus than wearing only 1 mask. The CDC now recommends double masking, rather than just wearing 1 mask. If you only wear 1 mask, it should be tight fitting around the nose and mouth.

Wearing a face mask does not replace social or physical distancing. If you are out in public and not vaccinated, you should do both: practice physical distancing of at least 6 feet (2 meters) from other people and wear a mask.

There is no scientific evidence that taking zinc or vitamin C, even at high doses, can help to prevent COVID-19. Using mouthwash and nasal rinses, or ingesting mouthwash in large amounts, also will not prevent COVID-19 and can be dangerous.

Are there special precautions that people with cancer should take?

People with cancer, people who are in active cancer treatment, older patients, and people with other serious chronic medical conditions, such as lung disease, diabetes, or heart disease, are at higher risk for the more severe form of COVID-19 that could lead to death. Studies have shown that people with active or progressing cancer may be at higher risk than those whose cancer is in remission. The same rules apply for people with cancer as for those without cancer: Be sure to wash your hands well, and wash them frequently. Avoid touching your face, and avoid close contact with people who are sick.

People who are at higher risk of getting very sick from COVID-19 should avoid any non-essential travel during the COVID-19 pandemic. This is especially important for people who have not yet been fully vaccinated against COVID-19. If you are not vaccinated, stay at home to reduce your exposure to the virus, practice physical distancing, and avoid social gatherings, including smaller gatherings with family or friends who don't live with you. Wear a cloth face covering or mask, and make your trip out as brief as possible. If you have been vaccinated, you are able to return to normal activities. However, some places may continue to require masking and physical distancing.

If you are vaccinated, outdoor activities are safe without physical distancing. If you are not vaccinated, walking or exercising outdoors is fine as long as the area is not crowded and you are able to keep a distance of at least 6 feet (2 meters) from other people.

A good rule of thumb during emergency situations such as the pandemic is to keep enough essential medications, both prescription and over-the-counter, to last for at least 1 month. Create and keep updated an emergency contact list that includes family, friends, neighbors, and community or neighborhood resources who may be able to provide information or assistance to you if you need it.

In order to stay connected to your support system, connect with your family and friends virtually, through video chats or phone calls. Some examples of technology that can be used for video or other live chats are FaceTime, Zoom, Google Hangouts, and social media platforms, such as Instagram and Facebook.

If you are scheduled for cancer treatments, have a discussion with your oncologist about the benefits and risks of continuing or delaying treatment. If you are not scheduled for cancer treatment but are scheduled for an appointment with your oncologist, it may be possible for the doctor to conduct the visit using videoconferencing or telemedicine. Be sure to check with your cancer care team to see if this is recommended for you.

Finally, it is always important to have your health care wishes in writing, in case you are too sick to make decisions for yourself. This way, your family and your medical team will know what is important to you and what your wishes are. If you have not yet done this, now is a good time. Cancer.Net has valuable information on this topic. Because some hospitals and clinics are limiting visitors, and some are allowing no visitors, having your health care wishes in writing is more important than ever. Here are some examples of important questions to ask yourself, to discuss with your loved ones, and to write down:

  • What level of quality of life would be unacceptable to me?

  • What are my most important goals if my health situation worsens?

  • If I am unable to speak for myself, who is the person in my life who I would want to speak for me?

  • Who should not be involved in making decisions for me?

  • If my heart stops, do I want to have CPR (cardiopulmonary resuscitation) done?

Will anything change with my cancer-related medical visits?

Due to the COVID-19 pandemic and the increased risk of exposure to the virus by going out in public, most hospitals and clinics have changed their visitation policies. Some may allow 1 visitor per patient, and others may allow no visitors. Masks and physical distancing will likely still be required. Before heading to your medical appointment, check with the clinic or hospital for their current visitor policy.

Your cancer care team may conduct some of your appointments by telemedicine. During a telemedicine appointment, you are able to stay at home and visit with your doctor or other health care team member through video conferencing using your phone or computer. Your doctor’s office will give you instructions on how to have your visit this way. If you are interested in having a visit by telemedicine rather than in person, ask your doctor's office staff if this is possible. 

If community spread of COVID-19 in your area is high, your doctor may recommend delaying some treatments for supportive care, such as bone-strengthening treatments, for example, denosumab (Xgeva) or zoledronic acid (Zometa), or intravenous iron supplementation. They will only recommend delaying treatments if they feel it is in your best interest to do so. 

Early in the pandemic, cancer screening tests, such as mammograms or colonoscopies, and other tests, such as bone density tests, were often delayed to reduce your risk of exposure to the virus. However, it is still important to receive regular cancer screening, even during a pandemic. The Prevent Cancer Foundation’s Back on the Books website can help you learn more about COVID-19 and safe cancer screening. 

For people who are at high risk of cancer, such as those with a hereditary cancer syndrome like Lynch Syndrome or a BRCA mutation, your doctor may recommend delaying some cancer risk-reducing procedures. They will only recommend this if they feel it's safest for you, based on the virus transmission rates where you live and your own personal risk. It's always best to discuss timing of these tests and procedures with your doctor.

What should I do if I think I may have COVID-19?

Call ahead before visiting your health care professional or the emergency department if you have a fever and other symptoms of a respiratory illness, such as cough and shortness of breath. Let them know if you think you may have COVID-19. They will ask you questions about your symptoms, travel history, exposure, and medical risk factors to find out if you should be tested for COVID-19. They will then give you instructions on how to get tested in your community. It is important to note that even if you are vaccinated, you may still develop COVID-19, but the risk is very low and the illness is likely to be mild.

A common question I hear from patients is about which doctor to call. I recommend calling the doctor who you have the most contact with. If you have been off cancer treatment for more than a year and are seeing your primary care provider regularly, you may call your primary care provider. However, if you are seeing your oncologist more regularly or are on active cancer treatment, call your oncologist.

If you are receiving cancer treatment that suppresses the immune system and you develop a fever and respiratory symptoms, call your oncologist as you usually would if you develop a fever while on treatment. Be sure to follow their guidance on when to come into the office or hospital and when it’s safer to stay home.

Severe symptoms could be a medical emergency, and you may need to call 911. If you or your loved one has symptoms, such as trouble breathing, persistent pain or pressure in your chest, new confusion, or bluish lips, you should seek medical attention immediately.

Testing for COVID-19 involves inserting a 6-inch-long swab, similar to a Q-tip, deep into the nasal cavity for at least 15 seconds. The swab is inserted into a special container and sent to a laboratory for testing. Saliva tests are also available in some areas. There are several FDA-approved at-home self-collection kits for this virus, approved under an emergency-use authorization. These tests often include a medical screening questionnaire and up-front payment, and the samples are sent to a lab for testing. The FDA has also given emergency use authorization to an over-the-counter, at-home test that can give results in about 20 minutes. This test involves a nasal swab that can detect fragments of the virus, if they are present. You should discuss with your doctor whether these are the right tests for you. If you decide to take an at-home test, be sure to let your cancer care team know the results.

If it is possible that you have COVID-19, you should stay at home and isolate yourself while you are tested and waiting for your test results. Staying home when you are sick is the best way to prevent transmitting the novel coronavirus and other respiratory viruses, such as the flu, to other people. If you live with someone, you should quarantine yourself in one part of the home, if possible, to lower the risk of spreading the virus to the rest of the people who live with you.

If you are concerned that you’ve been exposed to someone with COVID-19, closely watch for developing symptoms. Check your temperature regularly for fevers. If you have active cancer or are currently in cancer treatment, let your medical team know about your possible exposure.

On June 3, 2020, a study was published in the New England Journal of Medicine that included 821 people with no symptoms of COVID-19 who had a household or work exposure to COVID-19. This study showed that treatment with hydroxychloroquine after an exposure to someone with COVID-19 did not provide any benefit.

Is there a way to find out if I have already had COVID-19?

Antibody tests, also known as serologic tests, have been developed, and these tests may be able to find out if you have already had a COVID-19 infection by identifying whether there are antibodies in the blood. Antibodies are specific proteins made by the body in response to an infection.

Antibody tests are not perfect. Some people who get COVID-19 may not make antibodies. Or they may make very low levels of antibodies. Some people may have a “false positive” antibody test, meaning the test finds antibodies, but the antibodies are related to a different coronavirus and not COVID-19.

Antibody tests should not be used to make a current diagnosis of COVID-19. It can take between 1 and 3 weeks after the infection for the body to make antibodies.

If you have had a COVID-19 infection, whether diagnosed through a test for the virus or through an antibody test, it is possible (but not certain) that you may have immunity for about 3 months. However, if suspicious symptoms develop within that 3-month period after the COVID-19 infection, another test for COVID-19 is recommended, unless there is another obvious cause for those symptoms.

If I have had COVID-19, will I be able to continue cancer treatment?

If you have tested positive for COVID-19, you should have a discussion with your oncologist about the impact of this on your cancer treatment. Some cancer treatment centers may require a negative COVID-19 test before chemotherapy or other cancer treatment starts again. However, some patients with COVID-19 continue to test positive even after recovering from their symptoms. In this situation, your health care team will consider the risks and benefits of restarting cancer treatment despite the positive test. Some treatments, especially those that do not impair the immune system, may be able to continue, especially if you have tested positive for the virus but do not have symptoms or have only mild symptoms.

When your cancer treatment resumes or continues after COVID-19, it is important to wear a mask when coming to the infusion clinic or cancer treatment center and to practice good hand hygiene by using hand sanitizer or handwashing before and after visits.

Are there any treatments available for COVID-19?

There are no cures for COVID-19. Scientists are working hard to develop and test treatments for COVID-19. Clinical trials are research studies that involve people. Working very quickly, researchers and physicians have developed clinical trials to find effective treatments for this disease. Clinical trials for potential COVID-19 treatments are now open in many locations in the United States and in other countries. If you have been diagnosed with the coronavirus disease and you join a clinical trial for patients with COVID-19, you may be able to receive these medications. Also, by joining a clinical trial, your participation will help scientists find the most effective and safe treatment for the illness. The NCI COVID-19 in Cancer Patients Study (NCCAPS) and a study at Stanford, for example, are designed to collect symptoms from people who may have COVID-19 to help researchers learn the course of the disease and help find a treatment.  

Remdesivir, an antiviral medication, may be helpful in treating COVID-19 infections. The drug received an Emergency Use Authorization from the FDA on May 1, 2020, and became the first FDA-approved treatment for COVID-19 on October 23, 2020. Remdesivir is approved for patients with COVID-19 who require hospitalization. It may decrease time spent hospitalized but does not prevent death.

Bamlanivimab is an antibody treatment given by vein (intravenously) that was given an FDA Emergency Use Authorization on November 9, 2020, for the treatment of people ages 12 and older who test positive for the SARS-CoV-2 virus and are at risk of having severe COVID-19 or hospitalization. This drug is still being studied in clinical trials, but early information seems to suggest that it may reduce hospitalizations or emergency room visits in some patients. Two more intravenous antibodies, casirivimab and imdevimab, were given FDA Emergency Use Authorization on November 21, 2020, for the treatment of mild or moderate COVID-19 in patients who are at high risk for developing more severe disease. These 2 antibodies are given together. None of these newest antibodies are for people who are receiving oxygen or who are hospitalized.

Dexamethasone, a steroid medication, can be beneficial for critically ill patients with COVID-19. A report from the U.K. Recovery Trial found that dexamethasone can help save lives in people who require oxygen therapy or are on a ventilator. In this population of very ill patients, receiving dexamethasone resulted in a lower rate of death at 28 days. The drug unfortunately does not seem to help in cases of mild disease.

Convalescent plasma is the liquid portion of blood that can be collected from people who have recovered from COVID-19. This plasma may have antibodies to SARS-CoV-2. Convalescent plasma is being studied in clinical trials as a possible treatment, and the FDA issued an Emergency Use Authorization for it on August 23, 2020. However, its benefits and risks still have not been confirmed in randomized clinical trials. If you have fully recovered from a COVID-19 infection, you may be able to donate your plasma at a blood bank in your area in order to potentially help others. Learn more about donating convalescent plasma at the websites of the Red Cross and AABB (formerly known as the American Association of Blood Banks).

Hydroxychloroquine (Plaquenil) initially seemed promising as a possible treatment for COVID-19, but after various clinical trials reported data on its safety and effectiveness, this medication was not found to be helpful. Hydroxychloroquine is not recommended for the treatment of COVID-19, either alone or in combination with any other drugs.

A version of chloroquine (chloroquine phosphate) is used as an additive to clean fish aquariums. Consuming this fish tank additive has led to at least 1 death and other overdoses. Do not consume this product—it can kill you.

Drinking bleach or injecting bleach or other household disinfectants is very dangerous and can kill you. Another proposed treatment to avoid is oleandrin, an extract that comes from a toxic shrub. Ingesting even a small amount of the plant can kill you. These are not treatments for COVID-19, and they will not help prevent it.

Do not take ivermectin, a drug used to treat parasites and head lice. Ivermectin products are made differently for animals and for humans. Ivermectin is not an antiviral medication. Taking this medication has not been shown to be helpful in treating COVID-19. Consuming it, especially at doses recommended for animals, can be dangerous and may result in overdose, hospitalization, and death.

How do we return to school or work safely?

Around the world, there is variation in whether or not schools and offices are open. In the United States, local and state officials have worked with school systems to plan school openings. Some schools are offering only in-person education, a small number of schools are completely virtual, and others still are offering some blend of the two.

If you or your children are returning to school in person, and especially if you are not vaccinated against COVID-19, wearing a face covering or mask that covers the nose and mouth at all times is important to lower the risk of spread. If physical distancing is possible, please do so. Use hand sanitizer frequently and wash hands whenever possible. Stay home or keep children at home if they are sick or have a fever.

When returning to in-person work, the same rules apply. Being vaccinated against COVID-19 is the safest approach. If you are not vaccinated, avoid large gatherings of people, physical distance as much as possible, and wear a mask at all times. Regularly clean desks and other frequently touched surfaces. If there has been a known exposure to COVID-19 in the space, then cleaning with disinfectant wipes is important. Do not go to work when you are sick or if you have a fever.

Finally, be sure to get a flu shot during flu season. This can help protect you and those around you.

When will things return to normal?

The rates of infection from the virus have fluctuated since early 2020, but the virus has not gone away and it likely won’t anytime soon. Overall, in the United States, the number of cases of COVID-19 and the number of deaths from the virus have continued to increase, though rates fluctuate in various communities and countries. With COVID-19 vaccines now widely available in the United States, a return to normal is expected, but access to vaccines varies from country to country. Masking and physical distancing continue to be important, especially indoors and for those who are not vaccinated. Masks will likely continue to be required in health-care settings.

If your local community, county, or state has allowed nonessential businesses to reopen or remain open and if you are not vaccinated against COVID-19, the safest approach is to continue to stay at home and avoid being in public as much as possible. Wear face masks and consider double masking when you leave your home. Stay at least 6 feet (2 meters) away from other people.

If you decide to eat at a restaurant, it’s safest to eat outside, and you should still wear a mask if you are not vaccinated, unless you are eating or drinking. People who are vaccinated can feel more comfortable resuming pre-pandemic activities, such as dining in a restaurant and shopping.

Many people believe that a negative COVID-19 test means that it’s safe to gather with friends or family members outside of your household. However, this is not true. It is important to remember that a negative COVID-19 test only means that the person was negative at the moment of that test. The test only gives information about the level of virus at the exact time of the test. Someone could have COVID-19 but not yet have enough virus to test positive. Also, these tests are not 100% accurate.

The safest approach, especially if you are considered high risk and if you are not vaccinated, is to continue living as if the stay-at-home restrictions are still in place. If you have been vaccinated, it is now possible to ease back into social events.

If you have questions about your personal risk due to your cancer or cancer treatment, be sure to speak with your doctor for their guidance.

Where can I get the latest information about COVID-19?

Staying up to date on the latest information on the COVID-19 outbreak is important. The CDC and your local and state health departments will have ongoing information about whether the disease has been diagnosed in your community.

This information is also available in Spanish, Portuguese, Russian, and Arabic (PDF)
