Hood River County Health Department Chief Health Officer Dr. Christopher Van Tilburg says there is a surge of COVID-19 cases locally, but how many actual cases are occurring is difficult to tell.  That’s because some people are testing positive and not reporting it, some are testing negative when they are actually positive often due to not getting a good sample for a COVID test, some have mild symptoms and don’t test, and some are asymptomatic.  Van Tilburg said in a social media video post over the weekend that COVID vaccines are working, and most hospitalizations for COVID involve people who are unvaccinated.  Hood River County is holding a COVID-19 vaccination and testing event on Friday from 2 p.m. to 7 p.m. at the Mt. Hood Town Hall.
