Are there any effects on human skin from the blood of a bat?
Bats blood, like the blood of other animals (including humans!), is a fluid within the body that contains a number of important cells that act to transport oxygen, waste, important immune system components, and a number of essential compounds such as hormones and proteins around the body. In general it's safe to say there are little-to-no effects of bat blood, or any other animals blood, coming in contact with human skin. However, a few exceptions to this should be noted. It is possible to be allergic to a certain component of an animal's blood called serum, however this allergy is not readily developed and often results from prolonged contact with animal blood (say, if you worked with animal blood on a daily basis). It is also important to note that animal blood can contain certain blood born pathogens that can be transferred to humans if in contact with an open wound or mucous membrane. However, most pathogens dangerous to humans that bats can carry are not transmitted via blood. Rabies for example can only be acquired via open wound or mucous membrane exposure to bat saliva. Overall it's safe to say there are no effects of bat blood contacting human skin, however if you are bitten by a bat or are experiencing the symptoms of an allergic reaction, you should contact your local health care professional immediately.
