Use the COVID-19 Screener online tool

This always-on web tool allows patients who have symptoms of COVID-19 – or who are concerned about exposure to COVID-19 – to walk through a few automated online questions. At the end of the brief assessment, patients will be directed to next steps based on their health status.


Start screening

I have symptoms that I think might be COVID-19. Do I need a test?

If you have symptoms, you should get tested. Massachusetts has many testing options. If you live somewhere else, check your state website for resources. 

You can also use a home testing kit (often called antigen tests). The Centers for Disease Control and Prevention (CDC) has more information about home testing.

Please do not go to the emergency room or urgent care only to get a COVID-19 test.

Please note that Mass General Brigham has limited capacity for testing at this time. We are no longer able to offer elective testing (for example, testing for travel). We are adding testing capacity. We hope to be able to offer elective testing again soon.

Should I isolate or quarantine?

If you test positive for COVID-19, you should isolate. If you have been exposed to someone with COVID-19, you should quarantine. Read more from the CDC.

Guidance around the need for quarantine and testing after an exposure is changing. See the CDC, Massachusetts Department of Public Health, or your state website for the most up-to-date guidance.

Note that most Massachusetts public schools are following the Massachusetts Department of Public Health guidance. However, some schools may have different guidelines. Please call your child’s school to find out what their specific policy is on quarantining if your child has been exposed.

Am I at high risk for severe COVID-19?

High-risk conditions for severe COVID-19 include undergoing treatment for cancer, currently taking medications for transplant, or immunosuppressant medications for other conditions. Other high-risk conditions, including having chronic lung, kidney, or liver disease; diabetes; HIV; obesity; and age 65 years or older, may pre-dispose you to worse symptoms from COVID-19 or influenza. The CDC has more information.

I tested positive. I’m not at high risk for severe disease. I’m worried about my symptoms. What should I do?

Mild symptoms: Stay home and isolate

Mild symptoms are a temperature below 100 degrees (below 102.4 degrees for children older than 3 months), aches and pains, or a mild cough. If you have these symptoms, stay at home and isolate. Rest, drink plenty of fluids, and monitor your symptoms. Hopefully, you will start feeling better within a few days. You do not need to contact your doctor to let them know you have COVID. 

Moderate symptoms: Call your primary care office

If you have moderate symptoms like a fever higher than 100.4 degrees, significant coughing, or shortness of breath, contact your primary care provider’s office. 

For children ages 3 months and older who are not immunocompromised, a high fever is greater than 102.4 degrees. If your child has a fever, significant coughing or shortness of breath, you also should call their primary care provider’s office. You should also call if they are sleepier, if they have not gone to the bathroom in more than 10 hours (if 3 years or older) or more than 8 hours (if younger than 3 years old). Your child’s doctor can recommend next steps.

If you don’t have a primary care provider or you have symptoms that need immediate attention, try our Urgent Care options:

  1. Schedule an appointment with Mass General Brigham Virtual Urgent Care.

Severe symptoms: Emergency

Go to the Emergency Department if you have severe symptoms such as:

  • Severe trouble breathing
  • Persistent pain or pressure in the chest
  • New confusion or dizziness
  • Inability to wake or stay awake
  • Pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone

If you cannot get to the emergency department, call 9-1-1.

I tested positive and I’m at high risk for severe disease. I am worried about my symptoms. What should I do?

Call your primary care provider’s office.

You may be eligible for outpatient COVID treatment. Please note, we have limited supplies of these therapies.

For example, monoclonal antibody therapy (mAB) can help fight the infection. Call your primary care provider’s office to be referred. You are eligible if you are at high risk for severe COVID-19 and have either a positive antigen test or PCR test and are within 10 days of starting symptoms.

Note that mAB is not available at Urgent Care or the Emergency Department.If you are eligible, your doctor will refer you to a designated infusion clinic.

Also, the U.S. Food and Drug Administration has issued an emergency use authorizations (EUAs) for Pfizer’s Paxlovid (nirmatrelvir tablets and ritonavir tablets) and Merck’s molnupiravir. These are pills that can be used to treat mild-to-moderate COVID-19. Paxlovid is available for adults and children 12 years of age and older weighing at least 40 kilograms. Molnupiravir is for adults only. Both are available by prescription only for patients who are high risk for severe COVID-19. Both should be started as soon as possible after the diagnosis of COVID-19 and within five days of the start of symptoms. We do not yet have this treatment available but anticipate limited quantities soon. We will provide updates when it is available. Please do not call or message your doctors to request these drugs as they are not available right now.
