Most rabies infections in the United States come from bats, CDC says.In the United States, the culprit behind most rabies cases has shifted from dogs to bats. The flying mammals now cause 7 out of 10 US rabies cases, according to a report from the Centers for Disease Control and Prevention. 

 Researchers looked at rabies trends in the United States over the span of 80 years, from 1938 to 2018. They found that most infections came from dog bites until 1960, when wildlife species -- specifically bats -- became the primary source for human infection. 

This followed nationwide efforts in the 1950s to mandate pet vaccines and implement leash control laws, the report stated. "Reducing rabies in dogs is a remarkable achievement of the U.S. public health system, but with this deadly disease still present in thousands of wild animals, it's important that Americans are aware of the risk," CDC Director Dr. Robert Redfield said in a news release. 

From 1960 to 2018, 125 human rabies were cases reported . From 1960 to 2018, 125 human rabies were cases reported in the United States. Of these, 28% came from contact with dogs outside the United States, where rabies vaccines may not be required or readily available. 

The cases acquired in the United States came from wildlife species, with 70% resulting from bat bites or scratches and the rest due to human contact with raccoons, skunks or foxes. In the United States, most human deaths from rabies occur because people don't seek medical treatment, probably because they are unaware of the animal contact. 

For example, bat bites can be smaller than the top of a pencil eraser, the CDC said. "We've been seeing cases in people in the United States who seem to not really be aware that rabies can be transmitted by wildlife, especially bats," Pieracci said. "A lot of times, bat bites and scratches are very tiny. So a lot of people will try to hold a bat and they don't realize that bat has bitten."

 If you happen to wake up with a bat in your immediate surroundings, you should assume rabies exposure and seek medical care right away, the CDC recommends.
