First documented in 1958, the virus is named after the Canadian town where it first appeared. Symptoms include headache, vomiting, weakness, and in many cases, swelling of the brain.
Government statistics show that half of those infected will suffer permanent neurological damage.
…the utilization of the organ cultures is likely a bona fide way to rapidly assess the efficacy of gene inactivation methods as well as drugs and small molecule inhibitors as antivirals.”
Coppe Lab, a CLIA certified lab, right here Waukesha has been studying Powassan for quite some time. Their pdf below states that numbers look low because only severe cases are reported. Despite this, there’s been a 375% increase in the last 5 years.
They state the clinical picture of Powassan looks like many other tick-borne illnesses and is…
probably overlooked yet directly contributes to disease long term.
About two-thirds are subclinical but round 30% of symptomatic adults contract a severe form called meningoencephalitis. One-third of those have incomplete recovery with neuropsychiatric symptoms that become chronic. The overall fatality rate is about 1% and severity of illness increases with the age of the patient.
In 2016, Coppe Laboratories’ Study 1 evaluated 106 patientswith suspected acute tick-borne disease and 10.4% tested positive for POWV by immunofluorescence assay. Nearly 17% of the patients with positive Lyme results also tested positive for POWV exposure. The authors concluded,
“Infection with POWV may be underdiagnosed and may contribute to the persistent symptoms often associated with Lyme disease diagnosis.”16
Coppe states the following patients should be tested for POWV:
Coppe has developed both direct and indirect tests for Powassan virus and is the only commercial laboratory to offer this type of testing. See their pdf for case studies: http://www.coppelabs.com/wp-content/uploads/coppe-powassan_16pg_030818_lores_indiv.pdf
