Animal Contact & Human Health

• Immediately wash your wound with soap and water and seek proper medical attention.
• Anyone who is bitten by an animal is at risk of getting rabies, therefore contact your local animal control, local health department, or police to report the incident.

Cryptosporidiosis (also referred to as “Crypto”) is a diarrheal disease caused by a microscopic, single-celled parasite called Cryptosporidium parvum. Anyone can get cryptosporidiosis, but it may be more common in persons under two years of age, those who travel, work with animals, or are in close personal contact with infected individuals. People with weakened immune systems, such as people with HIV infection or receiving chemotherapy, are more susceptible to the disease. Cryptosporidium parvum has also been responsible for disease outbreaks in children and staff in daycare centers.

Escherichia coli (also called E. coli) are bacteria that normally live in the intestines of humans and animals such as cows. Most strains of the E. coli bacteria do not cause illness. However, strains that produce toxins, referred to as Shiga toxin-producing E. coli (STEC), can cause serious illness. E. coli O157:H7 is the most common type of STEC, but other types exist. Anyone can get an STEC infection, but young children and older adults are more likely to have severe Illness.

Giardiasis is an intestinal illness caused by a microscopic parasite called Giardia. It is a fairly common cause of diarrhea throughout the U.S. and the world. Anyone can get giardiasis, but it tends to occur more often in people in daycare centers, international travelers, and individuals who drink improperly treated surface water (such as hikers drinking from a stream or people swallowing water while swimming in a river or lake). The parasite has to enter the mouth to cause infection. This happens when people and animals infected with Giardia shed the parasite in their feces (stool) and the feces then contaminate surfaces, food, or water. People then can become infected by touching contaminated surfaces, getting the parasite on their hands and then putting their hands in their mouths, or by eating the contaminated food or swallowing the contaminated water.

These documents are meant to provide quick reference for animal healthcare providers in regard to common rabies exposure issues. More detail about rabies and rabies exposures can be found in the Virginia Guidelines for Rabies Prevention and Control. In addition, further information can be obtained from your local health department. A directory of local health departments can be found at http://www.vdh.virginia.gov/local-health-districts.

Cat scratch disease (CSD) is bacterial disease caused by Bartonella henselae. Cats are the main reservoir of this organism. Anyone bitten, scratched, licked or exposed to an infectious cat or kitten is susceptible to the disease. Any domestic cat has the potential to be a reservoir for this disease. Infectious cats usually appear healthy. Fleas and ticks that infest cats may be infected as well.

Hantavirus pulmonary syndrome (HPS) is a deadly disease transmitted by infected rodents through urine, droppings, or saliva.  Humans can contract the disease when they breathe in the virus that is on dust and other debris floating in the air.  HPS was first recognized in the southwest United States in 1993 and has since been identified throughout the United States.  One case has been identified in Virginia.  In 1993, a hiker on the Appalachian trail developed HPS.

Lymphocytic choriomeningitis (LCM) is a disease caused by the lymphocytic choriomeningitis virus (LCMV). The virus may be found in about 5% of wild mice throughout the United States. The virus can also infect pet rodents (such as mice, rats, hamsters, gerbils, guinea pigs, etc.). LCM is very rare in humans in the United States. People who have unprotected contact with rodents or their waste/bedding (e.g., owners of pet rodents, laboratory workers who handle infected animals, etc.) are at higher risk of infection. Virus is present in the blood and tissues of infected people; therefore, organ donation recipients have been infected if the donor was carrying the virus. People who have weakened immune systems (e.g., HIV-positive persons, organ-transplant recipients, etc.) are at higher risk of severe disease if infected.

Methicillin-resistant Staphylococcus aureus (MRSA) is a bacteria that is commonly found in nasal passages and skin of humans and multiple animals. Methicillin-resistant Staphylococcus aureus is resistant to beta-lactam antibiotics and in some cases to other antibiotics. Although MRSA is primarily found in people, animals can also be infected. MRSA has been recovered from animals including horses, dogs, cats, cows, and  pigs. Some of these animals have not been exposed to antibiotic therapy and in several of these cases the MRSA infection appears to result from human-to-animal transfer.

Monkeypox is a rare disease caused by the monkeypox virus, which belongs to the same group of viruses as smallpox.  Monkeypox virus was first found in laboratory monkeys in 1958.  It has also been found in different kinds of African rodents. The first human cases of monkeypox in the United States occurred in the mid-west in 2003.  Before 2003, the only human cases of monkeypox occurred in central and West Africa.

Plague is a disease caused by Yersinia pestis that affects rodents (e.g., squirrels, prairie dogs, or mice), other mammals (e.g., rabbits or hares), and humans. These bacteria are found in many areas of the world, including the United States. There are three forms of plague: bubonic, pneumonic (lung infection) and septicemic (bloodstream infection). Plague is rare in the United States, with an average of 7 human plague cases reported each year (range: 1–17 cases per year) in recent decades. Cases in the U.S. generally occur in rural and semi-rural areas in the west and southwest. Worldwide, about 1,000 to 2,000 cases of plague are reported every year.

Psittacosis is a disease that is caused by the bacteria, Chlamyda psittaci, and is often associated with psittacine (i.e., parrot type) birds kept as pets; however, this bacteria can also infect poultry and non-psittacine birds like doves and pigeons. Most human infections have been reported as having been related to exposure to pet psittacine birds, like parakeets.  Human illness with psittacosis has also been documented from exposure to poultry and free-ranging birds including doves, pigeons, birds of prey and shore birds.

Q fever is a disease caused by the bacterium Coxiella burnetii. The disease can occur in two forms: acute (short-term) and chronic (long-term). Q fever has been reported from most parts of the world. However, this disease is rare in the U.S., with fewer than 175 cases reported per year during 2005-2013. A total of 21 cases were reported in Virginia during 2005-2013.

Sheep, cattle and goats sometimes carry C. burnetii. It may rarely be carried by cats, dogs, rabbits, birds, rodents and ticks. The organism can survive for long periods in the environment (e.g., in dust, wool, straw, fertilizer, etc.).

Rat-bite fever (RBF) is bacterial disease caused by Actinobacillus muris and Spririllum minus. In the United States, rat-bite fever is primarily due to infection with A. muris. Rats are the main reservoir of these organisms. People exposed to infectious rat secretions may become ill. Direct contact with a rat is not necessary. RBF is rare in the United States, however, since it is not a notifiable disease, exact numbers of cases are not known.
