Cases of Varicella (Chickenpox) Associated with the Portland Expo Center

August 3, 2019 Advisory (PDF) 
Maine CDC is aware of cases of varicella (chickenpox) in individuals who are staying at the Portland Expo Center. Varicella is a contagious viral disease that can spread easily to individuals who have not had varicella and have not gotten the varicella vaccine. There are several diseases that can cause a febrile rash in children, so Maine CDC encourages laboratory testing when assessing patients when possible. If diagnosed with varicella, patients may return to their congregate living setting if clinically stable and indicated by a provider. Individuals staying at the Portland Expo are already considered exposed. Providers should encourage patients to practice good hand and respiratory hygiene and stay away from non-immune individuals as much as possible.

Human Powassan Case

July 24, 2019 Advisory (PDF) 
The purpose of this health advisory is to alert clinicians to the potential for human Powassan encephalitis disease activity in Maine and to consider testing for Powassan in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and early fall. Maine CDC was notified of a human case of Powassan encephalitis (POW) in a Maine resident who resides in southern Maine. The individual was symptomatic in late June and hospitalized. CDC Fort Collins confirmed the Powassan result in this individual. Powassan virus is transmitted to humans through the bite of an infected Ixodes tick. Signs and symptoms can include fever, headache, vomiting, weakness, confusion, seizures, and memory loss. Long-term neurologic problems may occur. Symptoms can begin anytime from one week to one month after the tick bite. There is no specific treatment, but people with severe Powassan virus illness often need to be hospitalized.

Increase in Legionellosis Cases - Greater Bangor Area, Penobscot County

July 12, 2019 Advisory (PDF) 
In the greater Bangor area, Penobscot County, Maine, physicians have reported 6 confirmed cases of legionellosis from November 2018 to the present. This is an increase from the 5-year median of 3.2 cases for Penobscot County. Cases range in age from over 50 to under 85 years old. Maine CDC is actively investigating the cases and has not identified a common exposure among cases. Health care providers should be aware of this increase in legionellosis cases and consider legionellosis in the differential diagnosis of any pneumonia case. Although urinary antigen assay is an adequate diagnostic test for Legionella, given the recent increase in number of cases, Maine CDC recommends respiratory specimen culture, particularly for patients who live in the greater Bangor area. Culture specimens can detect all species and serogroups of Legionella and may aide in exposure identification. Maine CDC requests Legionella isolates grown from respiratory specimens be sent to the Maine Health and Environmental Testing Laboratory (HETL) for further analysis.

Human Arbovirus Information for Healthcare Providers in Maine

July 2, 2019 Advisory (PDF) 
The purpose of this health advisory is to alert clinicians to the potential for human arboviral disease activity in Maine and to consider testing for arboviral disease in patients presenting with unexplained encephalitis, meningitis or high fever (100.4F or 38C) during the summer and early fall. Arboviral diseases, including Eastern equine encephalitis (EEE), Jamestown Canyon virus (JCV), and West Nile virus (WNV), are serious infections that are transmitted by the bite of an infected mosquito. Maine reported a fatal case of JCV infection, a relatively rare arboviral disease carried by mosquitoes, in a resident in 2018. Additionally, Powassan virus is an arboviral disease transmitted by the bite of an infected tick. Maine identified zero cases of Powassan virus disease in residents during 2018. Although rare, these diseases have potentially severe and even fatal consequences for those who contract them.
