Know What to Do

MaineHealth is here to guide you through symptoms, exposures and testing.


Genetic variations of SARS-CoV-2 (the virus that causes COVID-19) have been growing and changing around the world throughout the pandemic. Scientists track these viral variants through public health data, laboratory studies and other methods. Being fully vaccinated, including all recommended booster doses, is your best form of protection against COVID-19 variants.

Learn more about SARS-CoV-2 variants.

Masks are still required at all MaineHealth care locations. And even if you are fully-vaccinated and boosted, it is important to continue practices that help limit the spread of COVID-19. Wear a mask indoors in public if you are (or live with someone who is) at a high-risk for severe illness or, if you are in a high-risk community.

Learn more about COVID-19 community risk levels.



Quarantine helps prevent transmission of COVID-19 by keeping people who have been in close contact with someone with COVID-19 apart from others.

Learn more about quarantine and isolation guidance.

Even mild cold or allergy symptoms could be COVID-19. If you develop COVID-19 symptoms, or have been exposed to someone with COVID-19, get tested as soon as possible so you can get treatment if necessary.

See COVID-19 testing options.

People with COVID-19 have reported a wide range of symptoms that may appear 2-14 days after exposure to the virus.The most common symptoms* are:

  • Fever or chills
  • Cough
  • Difficulty breathing or shortness of breath
  • Fatigue
  • Repeated shaking with chills
  • Muscle or body aches
  • Headache
  • Sore throat
  • New loss of taste or smell
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea

If you develop COVID-19 symptoms, or have been exposed to someone with COVID-19, get tested as soon as possible so you can get treatment if necessary.

See COVID-19 testing options.

Seek immediate care if you develop more serious COVID-19 symptoms such as:

  • Difficulty breathing or shortness of breath
  • Persistent pain or pressure in the chest
  • New confusion or inability to wake up
  • Bluish lips or face

*This list is not all inclusive. Please consult your primary care provider for any symptoms that are severe or concerning.


Stay home except to get medical care.

  • Stay home: People who are mildly ill with COVID-19 are able to recover at home. Do not leave, except to get medical care. Do not visit public areas.
  • Do not go to your local hospital emergency room unless you are having serious symptoms such as:
    • Trouble breathing
    • Constant pain or pressure in your chest
    • Bluish lips or face
    • Sudden confusion
    • Having a hard time staying awake
  • Stay in touch with your doctorMonitor your symptoms. Be sure to get care if you feel worse or you think it is an emergency. If you have a medical appointment, call ahead and tell them you have or may have COVID-19. This will help the office protect themselves and other patients. 
  • Avoid public transportation: Avoid using public transportation, ride-sharing, or taxis.

Separate yourself from other people and pets in your home.

  • Stay away from others: As much as possible, you should stay in a specific “sick room” and away from other people in your home. Use a separate bathroom, if available.
  • Limit contact with pets & animals: You should restrict contact with pets and other animals, just like you would around other people.
    • If possible, have another member of your household care for your animals while you are sick with COVID-19. If you must care for your pet or be around animals while you are sick, wash your hands before and after you interact with them. See COVID-19 and Animals for more information. 

Wear a face mask.

  • Cover your mouth and nose with a cloth face cover when around others.
  • You could spread COVID-19 to others even if you do not feel sick. Everyone should wear a cloth face cover when they have to go out in public, for example to the grocery store or to pick up other necessities. 
    • Cloth face coverings should not be placed on young children under age 2, anyone who has trouble breathing, or is unconscious, incapacitated or otherwise unable to remove the mask without assistance.
  • The cloth face cover is meant to protect other people in case you are infected.
  • Continue to keep about 6 feet between yourself and others. The cloth face cover is not a substitute for social distancing.

Clean your hands often.

  • Wash hands: Wash your hands often with soap and water for at least 20 seconds. This is especially important after blowing your nose, coughing, or sneezing; going to the bathroom; and before eating or preparing food.
  • Hand sanitizer: If soap and water are not available, use an alcohol-based hand sanitizer with at least 60% alcohol, covering all surfaces of your hands and rubbing them together until they feel dry.
  • Soap and water: Soap and water are the best option, especially if hands are visibly dirty.
  • Avoid touching: Avoid touching your eyes, nose, and mouth with unwashed hands.

Avoid sharing personal household items.

  • Do not share: Do not share dishes, drinking glasses, cups, eating utensils, towels, or bedding with other people in your home.
  • Wash thoroughly after use: After using these items, wash them thoroughly with soap and water or put in the dishwasher.

Clean all “high-touch” surfaces everyday.

Clean high-touch surfaces in your isolation area (“sick room” and bathroom) every day; let a caregiver clean and disinfect high-touch surfaces in other areas of the home.

  • Clean and disinfect: Routinely clean high-touch surfaces in your “sick room” and bathroom. Let someone else clean and disinfect surfaces in common areas, but not your bedroom and bathroom.
    • If a caregiver or other person needs to clean and disinfect a sick person’s bedroom or bathroom, they should do so on an as-needed basis. The caregiver/other person should wear a mask and wait as long as possible after the sick person has used the bathroom.

High-touch surfaces include phones, remote controls, counters, tabletops, doorknobs, bathroom fixtures, toilets, keyboards, tablets, and bedside tables.

  • Clean and disinfect areas that may have blood, stool, or body fluids on them.
  • Household cleaners and disinfectants: Clean the area or item with soap and water or another detergent if it is dirty. Then, use a household disinfectant.
    • Be sure to follow the instructions on the label to ensure safe and effective use of the product. Many products recommend keeping the surface wet for several minutes to ensure germs are killed. Many also recommend precautions such as wearing gloves and making sure you have good ventilation during use of the product.
    • Most EPA-registered household disinfectants should be effective.

Monitor your symptoms.

  • Seek medical attention, but call first: Seek medical care right away if your illness is worsening (for example, if you have difficulty breathing).
  • Follow care instructions from your health care provider and local health department: Your local health authorities will give instructions on wearing a mask, checking your symptoms and reporting information.
  • Call 911 if you have a medical emergency. Notify the operator that you have, or think you might have, COVID-19. If possible, put on a face mask before medical help arrives.

Visit the federal CDC web page for the latest information on what to do if you feel sick.


What is COVID-19?

COVID-19 (also known as novel coronavirus) is a disease that causes flu-like symptoms which can lead to serious illness, hospitalization and death.

A novel coronavirus is a new coronavirus that has not been previously identified. The virus causing coronavirus disease 2019 (COVID-19), is not the same as the coronaviruses that commonly circulate among humans and cause mild illness, like the common cold.

Most COVID-19 cases are mild to moderate but anyone can have severe symptoms, including children and young adults. Older adults and people who have underlying medical conditions such as heart or lung disease or diabetes seem to be at higher risk for developing more serious complications such as severe respiratory illness or death.

Learn more about COVID-19.

How does it spread?

Anyone infected with COVID-19 can spread it, even if they do NOT have symptoms, even if they are fully vaccinated.

COVID-19 spreads when an infected person breathes out droplets and very small particles that contain the virus. These droplets and particles can be breathed in by other people or land on their eyes, noses, or mouth. In some circumstances, they may contaminate surfaces they touch. People who are closer than 6 feet from the infected person are most likely to get infected.

COVID-19 is spread in three main ways:

  1. Breathing in air when close to an infected person who is exhaling small droplets and particles that contain the virus.
  2. Having these small droplets and particles that contain virus land on the eyes, nose, or mouth, especially through splashes and sprays like a cough or sneeze.
  3. Touching eyes, nose, or mouth with hands that have the virus on them.
