The Parasites and Pathogens You Need to Avoid in the Wild - 2
by Tim MacWelch
It’s enough to make you sick, literally. But every year, outdoorsmen become ill from injesting pathogens in their game meat that could have been easily prevented. Maybe a dirty knife or unclean hands spread the contamination after butchering game, or your roasted rabbit was done too rare. It’s important to know what you are up against, and just as important to avoid or kill these nasties.
Only mammals get rabies; birds, fish, reptiles, and amphibians do not. Skunks, bats, foxes, raccoons, dogs, cats, and some farm animals are most likely to get rabies. Rabbits, squirrels, rats and mice, and small pets rarely get it.
If you are bitten by one of these animals, don’t panic—but don't ignore the bite, either. Wash the wound thoroughly with soap and lots of water. Washing thoroughly will greatly lessen the chance of infection. Give first aid as you would for any wound.
If possible, capture the animal under a large box or can, or at least identify it before it runs away. Call an animal control or law enforcement officer to come get it, if you can.
It's critically important that you notify your family doctor immediately and explain how you got the bite. Your doctor will want to know if the animal has been captured. If necessary, your doctor will give the anti-rabies treatment recommended by the United States Public Health Service. Your doctor will also treat you for other possible infections that could be caused from the bite.
Hantavirus Pulmonary Syndrome (Virus)
Nearly the entire continental United States falls within the range of one or more of these host species.
Early symptoms in humans include fever, headaches, myalgia, nausea, vomiting, diarrhea, dizziness, and chills. Later symptoms include severe respiratory distress due to pulmonary edema, which can be rapidly fatal. Humans are exposed through the inhalation of aerosolized rodent urine, feces, and saliva, as well as the handling of rodents. Prevention involves excluding rodents from homes and buildings including shelters and cabins, watching for signs of rodent infestation, and promptly removing any infestations. Those who regularly handle rodents are at increased risk for this disease and should contact the Centers for Disease Control and Prevention (CDC) for more detailed safety precautions.
Tularemia is highly infectious and can be transmitted by all known epidemiologic routes including bug bites, getting contaminated water in your eyes or mouth, blood or tissue contamination, inhalation and ingestion. Symptoms in people will vary depending on the route of exposure, but include fever and swollen lymph nodes, or pharyngitis and tonsillitis. Typhoidal tularemia presents with fever, chills, headaches, diarrhea, joint pain and weakness, and may be accompanied by bronchopneumonia. Pneumonia usually occurs after inhalation exposure.
People and other animals become infected when they accidentally ingest the infective eggs. Clinical signs vary depending on the dose and site of migration, but worms moving into eyes, brains and lungs are commonly reported. Larvae migrating in the brain produce traumatic damage and inflammation, resulting in progressive central nervous system disease. Sources of infection include any areas or objects contaminated with raccoon feces. Raccoons will often defecate at the same place over and over, with latrines being found at the bases of trees, logs and rocks; in barns, lofts, or garages; and on decks, woodpiles, and roofs.
