Why does the virus develop in some but not others?
A physician with MercyOne, Dr. Joseph McGargill, explains here that it is “multifactorial.” There are three main factors:
- Known or unknown pre-exposure- someone may have had COVID-19 before, and didn’t know. This means they probably had antibodies against the infection, so they didn’t get sick.
- Current exposure, although in close contact- it is possible that someone didn’t get a large enough antigen or virus exposure.
- Genetics- some bodies respond better to the COVID-19 virus. They may not show symptoms even after a positive test.
If someone close to you tests positive, it is important to act like you could end up sick. COVID-19 is most contagious two days before someone shows symptoms and three days after.
