(Portland, OR) -- Half of the residents in Multnomah County are expected to get the omicron variant of COVID-19. That's according to County Health Officer Dr. Jennifer Vines. She says the county has around 12-hundred new cases a day, and those numbers don't reflect people who test at-home and don't report the results. She says vaccinations remain the best way to avoid a serious illness from COVID-19 and potential hospitalization.
