Deer tick virus disease

Diagnosis and Treatment Serologic testing detecting the Powassan specific IgM antibody in serum or cerebrospinal fluid can be performed. Clinical presentation and risk of exposure are key factors taken into consideration when diagnosing.

Certain characteristics found in cerebrospinal fluid may also assist in diagnosis, including: Abnormal increase in the amount of lymphocytes and granulocytes. Protein in cerebrospinal fluid may be elevated slightly with normal glucose levels Multiple tiny strokes may be visible throughout the parietal and temporal lobes when an MRI is performed.

Gregory Poland, director the Mayo Clinic Vaccine Research Group, says there was a vaccine for humans, but it was withdrawn.

It's illogical. It's the bite of an infected blacklegged tick or deer tick that's responsible for making so many people sick with Lyme disease. There are no plans at this time for a new Lyme vaccine in the U.

A vaccine, VLA15, is being developed in Europe. Now they'll do phase 3 clinical testing, which means they go to the FDA, get approval, and they'll do very large studies.

Poland says it might take five years or more before a Lyme disease vaccine is ready for humans. Until then, it's important to be tick smart. And they will climb up the nearest object, like this blade of grass here. Mayo Clinic parasitic diseases expert Dr. Bobbi Pritt suggests permethrin for your clothing and gear.

Use permethrin on materials and DEET on skin. Spray the DEET repellent on exposed skin, including your legs and hands. Avoid your face, but be sure to protect your neck. Then, tuck your pants into your socks. And, on your hike, remember to avoid areas where those questing ticks may be perched. Mayo Clinic does not endorse companies or products.
