State public health director warns people to avoid contact with bats
Dozens of bat exposures already documented as we enter busy bat season
SPRINGFIELD, Ill. – Dr. Eric E. Whitaker, state public health director, is reminding everyone to avoid contact with bats as we approach the time of year when bats are the most active and health officials see the most bat exposures. Bats are the primary carrier of rabies in Illinois and already this year, 42 bats have tested positive for rabies in 22 counties.
“The Illinois Department of Public Health and local health departments throughout the state have already received numerous phone calls this summer about people being exposed to bats,” Dr. Whitaker said. “It is best never to approach a bat and, if found in a home or building, people should leave the bat alone and call their local public health department for assistance or instructions about removing it.”
Typically, 40 to 60 bats each year test positive for rabies in the state. In 2006, 46 bats tested positive for rabies in Illinois.
It is not possible from looking at a bat to tell whether it is rabid. People cannot get rabies just from seeing a bat in an attic, in a cave, at summer camp, or from a distance while it is flying.
“Children should be warned against petting or trying to assist a wild or unfamiliar animal. While our natural instinct may be to help or befriend bats or other animals that appear friendly or are injured, these animals can carry rabies and should be avoided,” said Connie Austin, state public health veterinarian.
Rabies is an infectious viral disease that affects the nervous system of humans and other mammals. Humans get rabies after being bitten by an infected animal or if infectious material from a rabid animal, such as saliva, gets directly into their eyes, nose, mouth or a wound. Without preventive treatment, rabies is a fatal disease.
Any wild mammal such as a raccoon, skunk, fox, coyote or bat, can have rabies and transmit it to humans. The animal does not have to be foaming at the mouth or be exhibiting other symptoms to have rabies.
Changes in any animal’s normal behavior such as difficulty with walking, or just an overall appearance of illness, can be early signs of rabies. For example, skunks, which normally are nocturnal and avoid contact with people, may appear friendly or ill and may approach humans during daylight hours.
A bat that is active during the day, found in a place where bats are not usually seen (such as in a home or on the lawn), or is unable to fly is more likely than others to be rabid. Such bats are often easily approached but should never be handled.
Over the past century, rabies incidence in the country has changed dramatically. More than 90 percent of all animal cases reported annually now occur in wildlife, while before 1960, most cases occurred in domestic animals. There is an average of one to two human cases of rabies in the United States each year, but no human cases have occurred in Illinois since 1954.
