Powassan encephalitis, caused by the Powassan virus (POWV), a flavivirus also known as the deer tick virus, is a form of arbovirus infection that results from tick bites.It can occur as a co-infection with Lyme disease, as both are transmitted to humans by the same species of tick. [1]
Powassan virus is an RNA virus split into two separate lineages: Lineage I, labeled as the "prototype" lineage; and Lineage II, the deer tick virus (DTV) lineage. [9] Lineage II has the most genetic variation, which indicates that it is most likely the ancestral lineage that split as a result of positive natural selection. [9]

The tick bite itself will likely be so small and painless (just a little red dot, if anything) that you won’t actually notice it, says Qurat Mudassar, MD, an infectious disease specialist and ...
A tick bite does not automatically transfer diseases to the host. Instead, the tick must be attached to the host for a period of time, generally 6–8 hours [9] but sometimes as little as 3–6 hours, [10] before it is capable of transferring disease. The earlier the tick is removed from a host, the less likely it is to contract the illness.
Deer tick 3D rendering of a male and female deer tick Ixodes scapularis is the main vector of Lyme disease in North America. [ 14 ] The CDC reported over 30,000 new cases of the disease in 2016 alone, the majority of which were contracted in the summer months, which is when ticks are most likely to bite humans. [ 15 ]
