About four percent of Oregon’s ED visits recently were due to influenza-like illnesses, according to the Oregon Health Alert Network. In general, flu illness has increased significantly, so providers are asked to review antiviral treatment guidance from the Centers for Disease Control and Prevention, which includes institutional settings, and share with colleagues. Unlike the rest of the country where A(H3) is the dominant strain, in Oregon 66 percent of flu-like hospitalizations are due to Influenza A.
