What is COVID-19?
COVID-19 is a respiratory disease that is caused by the virus SARS-CoV-2. Many people who are infected have mild symptoms or even no symptoms, but COVID-19 can also cause severe illness and death. Some people, including those who got no symptoms at first, get health problems that last for weeks or months.
Symptoms may also include: chills, muscle or body pain, fatigue, headache, sore throat, nausea or vomiting, diarrhea, congestion or runny nose, or new loss of taste or smell. This list of symptoms is not all inclusive. Please consult your medical provider for any other symptoms that are severe or concerning to you.
How It Spreads
The virus spreads when a person with COVID-19 releases respiratory droplets into the airÃ¢â‚¬â€for example, when speaking, singing, coughing, shouting, or exercising. These droplets are then breathed in by other people or land on their nose, mouth, or eyes. The virus also spreads by touching a surface with droplets on it and then touching your eyes, nose, or mouth but this is less common.
There are certain places where COVID-19 spreads more easily:
- Closed spaces with poor airflow
- Crowded places with many people nearby
- Close contact settings especially where people are talking (or breathing heavily) close together
Contact tracing is a simple, confidential process that has been used by public health departments for decades to slow the spread of infectious diseases and avoid outbreaks. You can do your part by answering a few simple questions when Public Health calls.
