In December 2019, a new coronavirus (SARS-CoV-2) started spreading. It can cause an illness called COVID-19. Some people may have mild symptoms, while some may have complications, like severe pneumonia.

According to the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO), common COVID-19 symptoms can include:

  • Fever
  • Chills
  • Cough
  • Shortness of breath or trouble breathing
  • Feeling tired and weak
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Stuffy or runny nose
  • Diarrhea
  • Nausea or vomiting

Other symptoms reported are:

  • Pinkeye
  • Painful blue or purple lesions (such as a sore or bruise) on toes (COVID toes)
  • Hives or rashes

If you have these emergency warning signs, call 911 or go to the emergency room immediately:

  • Trouble breathing or shortness of breath
  • Pain or pressure in the chest that doesn’t go away
  • Newly confused
  • Can’t wake up or stay awake
  • Cyanosis which is tissue color changes on mucus membranes (like tongue, lips, and around the eyes) and fingertips or nail beds – the color appears grayish or whitish on darker skin tones and bluish on lighter skin tones

This list may not include all symptoms. Symptoms may appear two to 14 days after coming in contact with the virus. If you have any symptoms that are severe or concerning, call your doctor.

How Can I Tell the Difference Between Asthma, COVID-19 (New Coronavirus), the Flu, a Cold, or Seasonal Allergies?

There are some symptoms that are similar between these respiratory illnesses and asthma. This chart can help you figure out if you may be feeling symptoms of asthma, allergies, or a respiratory illness like COVID-19, the flu, or a cold. If you have a fever and a cough, call your doctor right away. If you have seasonal allergies, there are things you can do to treat at home.

Information is still changing. We will update this chart as new evidence comes out.

What Do I Need to Know About the COVID-19 Vaccine?

Everyone 12 years and older can get the COVID-19 vaccines for free with no out-of-pocket costs in the United States. The Food and Drug Administration (FDA) has approved the Pfizer-BioNTech COVID-19 vaccine, called Comirnaty [koe-MIR-nah-tee], for ages 16 and older. The FDA has authorized the Pfizer-BioNTech vaccine for emergency use for ages 12-15. The FDA has authorized the Moderna and Johnson & Johnson (made by Janssen) COVID-19 vaccines for emergency use for ages 18 and older.

The vaccine reduces the chance of getting COVID-19. It can also reduce the severity of your symptoms if you get the disease.

You are fully vaccinated two weeks after getting your second Pfizer or Moderna shot or two weeks after getting one Johnson & Johnson shot. The CDC recommends that everyone in areas of high transmission wear a mask in public indoor places, even if they are fully vaccinated. 

Even if you are fully vaccinated, continue following CDC guidelines. Stay home as much as possible and wear a face mask. Keep physical distance and wash your hands to reduce the spread of coronavirus.

You are still required to wear face masks on public transportation, such as planes, buses, and trains. Hospitals, airports, train and bus stations, homeless shelters, and prisons still require everyone to wear masks.

Most people can get the COVID-19 vaccines with no issues. Allergic and adverse reactions are rare.

Talk with your doctor before you get a COVID-19 vaccine if you have a:

  • Moderate or acute (short-term) illness
  • Current case of COVID-19
  • History of severe allergic reactions (anaphylaxis) to a vaccine (not including COVID-19 vaccines) or injectable medicine
  • History of a severe or immediate allergic reaction to previous dose or any ingredient (also called “excipients” or “components”) of a COVID-19 vaccine
  • History of an allergic reaction to PEG or polysorbate
