Insect Bites, Wildlife Diseases, Dangerous Plants

Plague and Hantavirus

Plague and hantavirus are associated with wildlife found in these parks, but cases of human infection are rare. Rodents and their fleas can be carriers of plague, and humans can get plague if bit by an infected flea. Hantavirus is an airborne virus that comes from infected deer mice. Typically people contract hantavirus pulmonary syndrome after they clean areas or are in enclosed spaces with the feces of deer mice. If you see a dead rodent, notify a campground host or ranger.

Biting Insects

Ticks are common in grassy, brushy at low-elevation areas. They can carry diseases that harm humans. Check yourself for these insects after walks; their bite is painless. Tuck your pant legs into your socks when you walk in these areas to help you to spot them before they get to your skin. Remove them carefully with tweezers and seek a doctor’s advice.

West Nile virus is passed by bites from infected mosquitos. Human illness is not common but take steps to avoid mosquito bites.

Locations and numbers of insects vary by season and year to year. Be prepared!
