What diseases can be spread by flies?
The diseases that flies can transmit include enteric infections (such as dysen- tery, diarrhoea, typhoid, cholera and certain helminth infections), eye infections (such as trachoma and epidemic conjunctivitis) (Fig.
Can flies transmit diseases to humans?
The common housefly can transmit the pathogens that cause shigellosis, typhoid fever, E. coli, and cholera. The disease-causing agents can either be transmitted by the body hairs or by the tarsi which are transmitted to food or surfaces when the fly lands.
Can flies in your house make you sick?
Researchers suspect that house flies can harbor at least 65 illnesses that infect people. Some of the most common house fly diseases transmitted in the U.S. include food poisoning, dysentery, and diarrhea. These pests may also transmit the eggs of parasitic worms, which cause their own issues.
Do flies feed on blood?

Can a fly spread bacteria from one place to another?

In fact, every step taken by a fly can transfer live bacteria, researchers said. ”People had some notion that there were pathogens that were carried by flies but had no idea of the extent to which this is true and…
Why do flies carry more pathogens than people?
These findings suggest that flies carry more pathogens when they are around more people. “We believe that this may show a mechanism for pathogen transmission that has been overlooked by public health officials, and flies may contribute to the rapid transmission of pathogens in outbreak situations,” said Penn State biochemist Donald Bryant.
