COVID-19 Info & Vaccine
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
Shortness of breath or difficulty breathing
Muscle or body aches
New loss of taste or smell
Congestion or runny nose
Nausea or vomiting
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.

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.
