Connecticut has now had two in 2022. That’s two confirmed instances of individuals being contaminated with the Powassan virus. The primary one was a person in his 50’s who ended up being hospitalized for central nervous badness earlier than happily subsequently recovering. The second was just confirmed by the Connecticut Department of Public Health: a girls in her 90’s who sadly didn’t survive the tick-transmitted an infection.
The girl had an encounter with a tick someday in April. And ticks actually chew and suck, actually and figuratively. A tick carrying the Powassan virus solely wants quarter-hour or so to transmit the virus to somebody it’s biting. Two weeks after the tick was faraway from her physique, the lady started feeling ailing. Finally, her signs, which included fevers, complications, chills, shakes, chest ache, nausea, and altered psychological standing, led to her being admitted to a neighborhood hospital. She lapsed right into a coma after which finally died on Could 17.
Right here’s a WFSB Channel 3 Eyewitness Information report on Connecticut’s first human Powassan virus case of 2022, the person who acquired contaminated in March:
After all, two just isn’t a brilliant excessive quantity, until you might be speaking about wooly mammoths in your toilet. Powassan virus infections are nonetheless fairly uncommon with a complete of 12 reported instances in Connecticut from 2017 to 2021, two of them leading to deaths. Within the decade from 2011 by means of 2020, the variety of reported instances of neuroinvasive illness from the Powassan virus fluctuated from a low of six in 2015 to a excessive of 39 in 2019, according to data from the Centers for Disease Control and Prevention (CDC).
The query, although, is whether or not these probably life-threatening infections could also be getting rather less uncommon. Final 12 months, 2021, there have been three confirmed Powassan virus sicknesses within the “Structure State.” This 12 months there have already been two such instances with loads of tick, tick, ticks nonetheless left in tick season. Usually, Could by means of July is the height of tick season, though a second peak can happen within the Fall. In idea, although, any season may very well be tick season, as ticks are more and more hanging round all 12 months, which actually bites.
Furthermore, the variety of reported Powassan virus instances could also be simply the “tick” of the iceberg, so to talk. Not everybody contaminated will find yourself growing signs. And when signs do happen, they might be not more than delicate flu-like signs. Such instances might very properly go unrecognized and unreported. Thus, the virus may very well be getting extra widespread with out public well being officers even figuring out it.
Naturally, the asymptomatic and delicate instances aren’t the largest concern. As demonstrated by the 2 instances in Connecticut this 12 months, the virus can do an actual variety of your central nervous system. And also you want your central nervous techniques to do necessary stuff like take selfies. As I coated for Forbes a 12 months in the past, in some instances, a Powassan virus an infection can progress to meningitis, which is irritation of the membranes that wrap across the mind and spinal twine or encephalitis, which is when the mind itself will get infected. After all, should you have been to decide on which a part of your physique you’d need infected, your mind and membranes wrapping your mind would rank close to the underside of the checklist. Such irritation might result in a number of neurological issues and probably dying. The Connecticut Division of Public Well being announcement indicated that “about one out of 10 instances of extreme sickness are deadly and roughly half of survivors expertise long-term well being issues.”
Since there may be presently no vaccine towards the Powassan virus and no particular therapy, one of the simplest ways to cope with the virus is to not get it within the first place. Meaning avoiding ticks. Three kinds of ticks can carry the Powassan virus. Two of them Ixodes cookei, in any other case often known as the groundhog tick, and Ixodes marxi, in any other case often known as the squirrel tick, don’t are likely to chew people. So until you’re a large groundhog, you don’t have to fret about these two kinds of ticks as a lot. However oh deer, it’s the deer tick (Ixodes scapularis), in any other case recognized blacklegged tick, that likes to chew people and might provide the Powassan virus.

Such ticks have a tendency to hang around in grassy, brushy, or wooded areas. Due to this fact, it might be good to cancel your lying-naked-in-the-brush get together, particularly in case you are in Japanese U.S. the place the deer tick is extra frequent. Spraying your self with insect repellants, comparable to these containing DEET ( N,N-diethyl-meta-toluamide), will help repel ticks. So can treating your clothes and different gear with merchandise containing 0.5 p.c permethrin. However such issues gained’t function impenetrable full-body condoms. It’s best to nonetheless watch out and attempt to keep away from actually ticked off locations.
And repeatedly verify your self and others for ticks everytime you’ve been open air in locations that will have ticks. After all, ask earlier than you verify others for ticks. Saying after the very fact, “oh, sorry, I used to be simply checking for ticks,” normally doesn’t come off too properly. Showering will help, normally, but in addition with dislodging any ticks out of your physique. It’s best to verify your garments as properly, assuming that you simply put on garments exterior.
Whereas reported human instances of Powassan virus infections are presently fairly uncommon, the tick inhabitants within the U.S. has continued to develop. Local weather change has led to hotter temperatures which can be extra tick-friendly, permitting ticks to increase their habitats, as described by the U.S. Global Change Research Program (USGCRP) Climate and Health Assessment. And this WFSB 3 Information report talked about the “exploding tick inhabitants” in Connecticut:
Yeah, anytime you see the phrases “exploding” and “tick” subsequent to one another, likelihood is it’s not excellent news, assuming that you simply aren’t a large tick. It’s one factor for one thing to go viral on TikTok. It’s one other factor for entire lot extra ticks to be round to make extra people go viral with pathogens just like the Powassan virus.
