As health officials ask people to double down on efforts to stem the spread of COVID-19, they also advise that case numbers won’t drop right away.  Oregon Health Sciences University Health Chief Medical Officer Dr. Renee Edwards says that’s because when a person is infected with COVID, it can take two weeks for symptoms occur.  She says people should not be discouraged if they don’t see an immediate reduction in COVID numbers, and that it would probably take two or three weeks for them to come down if people increase their efforts to curb the spread.  Edwards was part of a press conference Tuesday of medical officials from around the state and Governor Kate Brown, asking Oregonians to use face coverings, maintain physical distancing, and refrain from social gatherings to reduce the spread of the virus and avoid overwhelming the health system.
