What is COVID-19? 


COVID-19 is a disease caused by a coronavirus called SARS-CoV-2. People with COVID-19 report various symptoms, including fever, cough, and shortness of breath. Symptoms of the new COVID-19 variant are similar to the viruses caused by other variants: sore throat, congestion, runny nose, cough, fatigue, and headache, among others.



People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. Anyone can have mild to severe symptoms. People with these symptoms may have COVID-19:

  • Fever or chills

  • Cough

  • Shortness of breath or difficulty breathing

  • Fatigue

  • Muscle or body aches

  • Headache

  • New loss of taste or smell

  • Sore throat

  • Congestion or runny nose

  • Nausea or vomiting

  • Diarrhea


The CDC will continue to update this list as we learn more about COVID-19. Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.

Guideines for Updated COVID-19 Vaccines 

Updated  January 30, 2024

Choosing Your Updated COVID-19 


Three COVID-19 vaccines are used in the United States to prevent COVID-19: Pfizer-BioNTech, Moderna, and Novavax. Pfizer-BioNTech and Moderna are both mRNA vaccines. Novavax is a protein-subunit vaccine.

What You Need to Know

  • The 2023–2024 updated COVID-19 vaccines more closely target the XBB lineage of the Omicron variant and could restore protection against severe COVID-19 that may have decreased over time. We anticipate the updated vaccines will be better at fighting currently circulating variants.

  • Updated COVID-19 vaccines can further enhance or restore protection that might have decreased over time after your primary series vaccination. 

  • People are protected best from severe COVID-19 illness when they stay up to date with their COVID-19 vaccines.

  • There are different COVID-19 vaccine recommendations for people who are moderately or severely immunocompromised.
