The Michigan Department of Health and Human Services (MDHHS) is seeing
an uptick in bats testing positive for rabies. As of [Thu 28 Jun
2018], the MDHHS Bureau of Laboratories has identified rabies in 22
bats and 2 skunks. Last year [2017] at this time, MDHHS had identified
9 bats with rabies. Michiganders are reminded to adopt practices that
protect their families and animals from rabies.

Rabies is a viral disease of mammals that is transmitted through the
bite or scratch of an infected animal. Bats and skunks are the most
common carriers of rabies in Michigan. In 2017, there were 38 cases of
rabies in animals in Michigan, including 35 bats, 2 skunks, and one
cat.

Michigan local health departments experience an increase in calls from
citizens about bat encounters during the warm weather months between
May and September. During this time, bats are more active, searching
for food and rearing their young. While bats are beneficial to our
ecosystem, they are also one of the species of animal that is a
natural host for the rabies virus.

People or pets usually get exposed to rabies when they are bitten by
an infected animal. Other situations that may present a risk are when
a bat is found in a room with people who have been asleep, or a bat is
found with an unattended child or impaired adult who cannot be sure
they didn't have contact with the bat. In these cases, it is important
to collect the bat for rabies testing.

Rabies is [almost always] fatal to humans. Post exposure treatment
[prophylaxis] is given to people who are exposed to a potentially
rabid animal. Treatment is not necessary if the animal tests negative
for rabies.

Despite its ability to infect all mammals, rabies virus persists in
numerous species-specific cycles that rarely sustain transmission in
alternative species. Genetic evidence suggests that rabies is an old
disease for bats in the New World. Bats from most of the bat species
in North America, when sampled in sufficient numbers, have been found
to be infected with rabies virus.

Rabies viruses recovered from bats were shown to be distinct from
rabies viruses recovered from terrestrial mammals, suggesting that
these viruses evolved within their bat hosts.

Bat rabies viruses of bats are genetically diverse, exhibiting
mutations characteristic to each host bat species. It should be taken
into account, however, that bat rabies can be transmitted to humans
and their domestic animals, with the infections almost always fatal,
unless treated. Also, a dog or a cat infected with a bat rabies virus
can infect a human. - Mod.PMB
