Powassan virus, a cousin to Zika and Dengue in the flavivirus family, is a rare tick-borne infection that is becoming more widespread in the northern U.S. Powassan symptoms include fever, nausea and headaches. In severe cases, it can lead to brain swelling and potentially be fatal. Given how dangerous this virus is, it can only be studied in special, high-security labs.
