Influenza Arrives in Maine
Influenza has arrived in Maine. Multiple Maine facilities reported influenza positive rapid results in recent weeks, and Maine's Health and Environmental Testing Laboratory (HETL) has just confirmed two cases using real-time reverse transcription-polymerase chain reaction (real time-RT PCR) testing. Both specimens tested positive for influenza A/H3. These individuals are adults who were not hospitalized. One patient was unvaccinated, and the vaccine status remains unknown for the other.
The 2021-2022 influenza surveillance season officially began on October 3, 2021. Though seasonal influenza activity in the United State remains low, both Influenza A and B viruses are currently circulating nationally. It is not too late to get vaccinated.
