Last week, the Maine Center for Disease Control and Prevention published the following information:
They were notified of two cases of Powassan encephalitis. Both cases occurred in adults who reside in the Midcoast area. In the two cases, the individuals became ill in late April and were hospitalized. The cases were confirmed through testing at CDC Fort Collins. Both individuals were discharged from the hospital and are recovering. Powassan, also known as deer tick virus, has been around since 1958, when it was discovered in Powassan, Ontario. Cases are rare in the U.S., and Maine has identified nine cases since 2000, including these two.
