Ticks and mosquitoes may await the pandemic-weary seeking outdoor exercise

Pandemic-weary Americans have begun walking and hiking in recent months to get out of the house while avoiding infection with the novel coronavirus. At the same time, resource-strapped local health departments have been forced to divert money and people to covid-related activities, unwillingly creating openings for outside exercisers to get sick in other ways.

Tick Awareness and Prevention for Hunters

With an estimated 899 species of ticks world-wide—and over 90 different types within the U.S. —the odds of coming across one of these pesky parasites during a hunt are pretty high. While certain ticks are incredibly problematic for large ungulates—and have led to a massive decline in moose within New England and British Columbia—only a handful of tick species actually harm humans.
