(Vancouver, WA) -- The Clark County Health Department is warning that COVID-19, flu and RSV infections are pushing hospital emergency departments and urgent care facilities to their limits. Clark County Health Officer Dr. Alan Melnick says getting vaccinated against flu and COVID-19 along with taking precautions to avoid getting a virus will help. You should only go to an E-R if you're having a health emergency, such as trouble breathing. Treat your symptoms at home or call your primary care doctor for advice. Flu cases are increasing, with a 25-percent test positivity rate in Clark County.
