Animal to Human Diseases
Rabies is a preventable viral disease of mammals most often spread through infected saliva from wild animals by a bite or scratch. The most common carriers of rabies are skunks, bats, raccoons, coyotes, but all mammals are susceptible to infections, including both you and your pets.
Be cautious of animals that exhibit signs of rabies, such as disorientation, fearfulness, aggressiveness, excessive drooling, or difficulty swallowing. Generally, a lack of fear of humans is also unusual behavior for wild animals. Report stray or ill animals to animal control by calling 303.438.6400 and protect your pets and livestock by keeping rabies vaccinations up-to-date.
Protect Yourself, Your Pet, and Your Community
PREVENT
Visit your veterinarian with your pet on a regular basis and keep rabies vaccinations up-to-date for all cats, ferrets, dogs, horses, and livestock.
PROTECT
- Avoid contact with any wild animals, especially any that act unusual. A healthy wild animal will generally avoid human contact.
- Maintain control of your pets by keeping cats and ferrets indoors and keeping dogs under direct supervision and on a leash.
- Observe wild animals from a distance. Never feed or handle unfamiliar animals or wildlife even if they appear friendly.
- Avoid leaving food or garbage outside as it often attracts stray dogs, cats, and wildlife to your yard.
REPORT
- Report any wild animal acting strangely to Broomfield Animal Control at 303.438.6400.
- Contact your veterinarian if your dog, cat, or ferret is bitten or scratched by a wild animal.
- Seek immediate medical attention if you are bitten or scratched by an animal, or had any contact with a wild animal, then contact Broomfield Public Health at 720.887.2220. Rabies post-exposure vaccinations may be needed immediately to prevent the development of rabies.

Hantavirus pulmonary syndrome (HPS) is a rare but serious disease that occurs throughout the U.S. and is caused by a virus that individuals get through contact with an infected rodents urine, droppings, or saliva. In the U.S., deer mice are the reservoir of the HPS. The virus is mainly transmitted to people when they breathe in air contaminated with the virus. Rodent infestation in and around the home remains the primary risk for hantavirus exposure. |
Symptoms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Early Symptoms
Early symptoms include fatigue, fever and muscle aches, especially in the large muscle groups-thighs, hips, back, and sometimes shoulders. These symptoms are universal. There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. About half of all HPS patients experience these symptoms.
Late Symptoms
Four to 10 days after the initial phase of illness, the late symptoms of HPS appear. These include coughing and shortness of breath, with the sensation of, as one survivor put it, a "tight band around my chest and a pillow over my face" as the lungs fill with fluid.
Uncommon Symptoms
Earache, sore throat, runny nose, and rash are very uncommon symptoms of HPS.

Plague occurs naturally in Colorado. Bubonic plague is the most common form of plague. This occurs when an infected flea bites a person or when materials contaminated with plague bacteria (Yersinia pestis) enter through a break in a person's skin. Plague is usually transmitted to humans by the bites of infected rodent fleas. Persons and animals that visit places where rodents have recently died from plague risk getting the disease from flea bites. Dogs and cats are also susceptible to plague and may bring plague-infected fleas into the home. |

Bubonic plague should be suspected when a person develops a swollen gland or node, fever, chills, headache, and extreme exhaustion, and has a history of possible exposure to infected rodents, prairie dogs, rabbits, or fleas.
Precautions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- AVOID FLEAS by protecting pets with a flea treatment, and keeping pets on a leash and out of areas inhabited by rodents, such as prairie dogs and squirrels.
- STAY OUT of areas where rodents live. If you enter rodent prone areas, wear insect repellent and tuck pants cuffs into socks to prevent flea bites.
- AVOID all contact with rodents in the wild, including prairie dogs and squirrels; do not feed or handle them.
- DO NOT TOUCH sick or dead animals.
- PREVENT rodent infestations around your house: clear plants and materials away from outside walls, reduce access to food items, and set traps.
- TREAT known rodent sites around your home with flea powder or other insecticides.
- SEE A PHYSICIAN if you become ill with a high fever and/or a swollen lymph node. Plague is a treatable illness.
- SEE A VETERINARIAN if your pet becomes ill with a high fever and/or an open sore. Pets with plague can transmit the illness to humans.

Tularemia is caused by the bacteria Francisella tularensis. Tularemia is usually a disease that occurs in wildlife such as rabbits and rodents, and it can be present in the environment in soil and water for weeks.
People can get tularemia many different ways, such as during gardening and landscaping activities. The disease can also be transmitted by contact with an infected animal or from an insect that fed on an infected animal. The bacteria may cause pneumonia when it is inhaled, for example from mowing over an infected carcass (such as prairie dogs, cats, dogs, squirrels, rats or rabbits). Ticks, biting flies, and mosquitoes have been shown to transmit tularemia between animals and humans. Tularemia is not known to be spread from person to person.
Symptoms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- Symptoms of tularemia usually appear 3 to 5 days after exposure to the bacteria, but can take as long as 14 days.
- Symptoms may include abrupt onset of fever, skin ulcers, swollen and painful lymph glands, inflamed eyes, sore throat, mouth sores, diarrhea, pneumonia, chills, headache, muscle aches, cough, or difficulty breathing.
- Tularemia is treatable with common antibiotics.
- See your health care provider if you are ill with these symptoms

West Nile virus (WNV) is primarily a disease of birds, spread by infected mosquitoes to people; it is not transferred from person to person. The female Culex tarsalis mosquito, the species that transmits the virus, usually start emerging in late April or early May and continue transmitting the virus until the first hard frost, which usually is in September along the Front Range.
Protect yourself and your family from mosquito bites, especially from dusk (evening) to dawn (morning) when the mosquitoes that spread WNV are more active.
Symptoms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
No symptoms in most people
Most people (70-80%) who become infected with WNV do not develop any symptoms.
Mild symptoms in some people
About 1 in 5 people who are infected will develop a fever with other symptoms such as headache, fatigue, body aches, joint pains, vomiting, diarrhea, or rash. Symptoms begin between 2 to 14 days after being bitten. People with milder symptoms typically recover on their own, although some symptoms may last for several weeks.
Severe symptoms in a few people
Less than 1% of people who have mild symptoms will develop serious neurologic illness such as encephalitis or meningitis (inflammation of the brain or surrounding tissues).
- The symptoms of neurologic illness can include headache, high fever, neck stiffness, disorientation, coma, tremors, seizures, or paralysis.
- Serious illness can occur in people of any age. However, people over 60 years of age and/or people with certain medical conditions, such as cancer, diabetes, hypertension, kidney disease, and people who have received organ transplants, are at greater risk for serious illness.
- Recovery from severe disease may take several weeks or months. Some of the neurologic effects may be permanent.
- About 10% of people who develop neurologic infection due to WNV will die.

Practice the Four D's
- Drain standing water around the house since that's where mosquitoes breed. Be sure to empty old tires, cans, flowerpots, clogged rain gutters, rain barrels, and toys where puddles can occur.
- Dusk and dawn are when mosquitoes that carry the virus are most active, so limit outdoor activities or take precautions to prevent mosquito bites.
- DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide the best protection. Follow label instructions.
- Dress in long sleeves and pants to keep mosquitoes from biting.
