It’s Time Prevent Zoonotic Disease
Prevent Animal-borne (Zoonotic) Disease
As summer progresses, San Juan Basin Public Health (SJBPH) reminds community members that the risk of contracting certain animal-borne diseases increases. Zoonotic diseases are more common during warm weather months when humans and animals are frequently in close contact.
Since the start of the year, the state has reported three hantavirus case in La Plata, Jefferson and Garfield counties, four tularemia cases in Adams, Fremont, Larimer, and Weld counties, and one case of West Nile virus in Jefferson County.
SJBPH stresses the importance of controlling the presence of rodents and mosquitoes around homes as well as wearing insect repellant and appropriate clothing when heading outdoors. Additionally, keep your pets up to date on vaccinations, and protect your pets from fleas and ticks. Do not handle or feed wild animals, especially those that appear sick, and do not touch dead animals or animal waste. Remember to speak to your children about these precautions.
Rabies Rabies is an infectious viral disease that affects the nervous system of humans and other mammals. People contract rabies from the bite of a rabies-infected animal (rabid animal). If you have had a bat in your room while you were sleeping, it is important that the bat is trapped and tested for rabies. Please call SJBPH for further guidance or to report an encounter with a suspect animal.
Plague Plague is caused by bacteria that can be transmitted to humans by the bites of infected fleas or by direct contact with infected animals. Plague is frequently detected in rock squirrels, prairie dogs, wood rats, and other species of ground squirrels and chipmunks. SJBPH investigates prairie dog population die-offs for the presence of plague. Community members can report a suspected die-off to SJBPH.
West Nile Virus West Nile virus is carried by mosquitoes and can be passed on to humans through mosquito bites. This disease can cause encephalitis or inflammation of the brain, lining of the brain, and spinal cord. Remember to use insect repellent when going outdoors. Also, help reduce the number of mosquitos around your home by emptying standing water from flowerpots, gutters, buckets, pet water dishes, discarded tires, and birdbaths on a regular basis.
Hantavirus Pulmonary Syndrome (HPS) is a severe, sometimes fatal, respiratory disease. Hantavirus is carried by wild rodents, particularly deer mice, and is present in their droppings, urine, and saliva. Dried droppings or urine can be stirred up in dust and humans may contract hantavirus by breathing in the contaminated air. Before cleaning up droppings, be sure to wear a mask, ventilate the room by opening windows and doors, and spray down all droppings with a bleach solution before vacuuming or sweeping.
Tularemia is found in the rodent rabbit populations and is transmitted by insect bites, direct transmission, or inhalation and/or ingestion of the bacteria. The infective dose is very small and can persist for long periods of time in water, soil, and carcasses.
When mowing or landscaping:
- Don’t mow over sick or dead animals. When possible, check the area for carcasses prior to mowing.
- Use of masks during mowing and other landscaping activities may reduce your risk of inhaling the bacteria, but this has not been confirmed.
If you hunt, trap or skin animals:
- Use gloves when handling animals, especially rabbits, muskrats, prairie dogs, and other rodents.
- Cook game meat thoroughly before eating.
Tick Borne Diseases
Colorado tick fever is the most common tick-borne disease in Colorado, though most cases go unreported. It’s a viral illness characterized by fever, headache, body aches, nausea, abdominal pain and lethargy. Complete recovery may take two to three weeks. The disease is not life-threatening and infection results in lifelong immunity. There’s currently no preventative vaccine or effective treatment except to let the disease run its course.
Rocky Mountain spotted fever is a serious disease that’s transmitted by infected Rocky Mountain wood ticks. Symptoms include sudden onset of high fever, headache, chills, and muscle aches. A rash often appears a few days later. Prompt medical attention is extremely important because Rocky Mountain spotted fever can be fatal if treatment is delayed. The illness can be cured with antibiotics.
