In a recent development, Maryland has recorded its first travel-related death linked to a rare tick-borne virus, which was contracted by an individual during their visit to Canada. The Maryland Department of Health confirmed the presence of the Powassan virus in this individual on September 22. Powassan virus is an illness transmitted through the bite of an infected tick, as per a news release issued by the state’s health department on Friday.
Dr. Nilesh Kalyanaraman, the Deputy Secretary for Public Health Services, expressed sadness over this unfortunate incident, stating, “We are very saddened to report the first death due to the Powassan virus in our state. Powassan is very rare, and this is the first-ever case recorded in Maryland. The individual contracted the virus in Canada and returned to Maryland afterward.”
Health officials, however, do not believe there is a significant risk of local transmission of Powassan in Maryland. Nevertheless, they emphasize the importance of adopting good practices when in areas where ticks may be prevalent or, if possible, avoiding such areas altogether.
It’s worth noting that a resident of Gardiner, New York, had previously become the first reported death associated with Powassan virus in that state back in August.
Powassan virus is primarily transmitted to humans through tick bites, and while it remains a rare occurrence, reported cases of individuals falling ill due to this virus have been on the rise in recent years, according to the Centers for Disease Control and Prevention (CDC). Importantly, the virus is not typically transmitted from person to person, except in extremely rare cases involving blood transfusion.
Symptoms associated with Powassan virus can include fever, headaches, vomiting, loss of coordination, memory issues, and speech problems. However, it’s worth noting that the virus often presents with no symptoms at all. In severe cases, it can lead to conditions like encephalitis and meningitis.
In the year 2022, the CDC received reports of 44 cases of Powassan virus disease across various states, with seven reported fatalities. In the current year, 2023, 28 cases have been reported to the CDC thus far.
The majority of cases tend to occur in the northeastern and Great Lakes regions of the United States during the late spring through mid-fall period when ticks are most active. Unfortunately, there are no vaccines available for preventing Powassan virus, and there are no specific medications for its treatment, according to the CDC.
