Yes, this happens all the time. Fleas typically prefer to live on other mammals like dogs and cats because they can hide in the fur coat easier. However, if a human is the only meal they can find, fleas will happily feed on humans with no problem.
A flea would much prefer to live off of the blood of cats, dogs, or other animals, than they would that of a human. It is extremely unlikely for a human to be infested with fleas, but singular flea-bites are not uncommon.
I'm sure its more likely for a flea to be transferred from an animal to a human, But I'm definetely possible for fleas to be transfered from humans to animals. Sorry if this answer doesn't exactly give you what you're looking for. :\
yes they can, when in contact to hair, or in contact (PERIOD)
Yes and the fleas can eat your brain and suck out all your sperm
Yes. They are quite talented in finding a host to feed upon.
Fleas don't care. Warm blooded mammal and they will attach and feed.
Yes definitely
probably they can if they had fleas lol :)
To kill fleas, it is good to fumigate the house or room in which they have spread. Fleas need to be sprayed with a strong chemical in order to control their spread.
It was spread by fleas, who normally host on rats, yet in some cases, they used humans as a host, and thus started the plague. It cannot be spread from human to human; only way is for the flea to infect you.
Insects such as mosquitoes, flies, ticks, fleas, bees, and wasps cannot spread HIV. If an insect bites a person with HIV, the virus dies as the insect digests the blood. HIV is only able to live in human cells.
There were several reason that this disease was spread from person to person. People at this time had no idea that bacteria even existed. The cites were so very dirty. People would throw their "slops" into the street (feces and urine), there were no sewer systems. This disease was really due to the bite of fleas. The fleas were carried by rats from place to place. The saliva of the fleas had the bacteria. At times the bacteria got into the lungs of the person and this produced something called pneumonic plague. A cough would spread this even faster and further.
Fleas living on black rats. Fleas, and the fleas spread on rats. Close quarters living (Castles, cramped city's due to walls) helped make it spread even faster.
fleas on rats
the plague was spread by fleas with the bacteria "Yersinia Pestis" inside their bloodstream or gut. the fleas would usually live on rats and jump onto humans when they had a chance. once the fleas bit the human, they would regurgitate the bacteria into the bite wound. the human would not care about the flea bite because in those times they would usually get bitten all the time. the flea would then live on the human, either until it dies, or it finds another victim
rats to fleas, fleas to humans, then human to human
Yes any flees in general will spread.
Fleas spread the plague
The black death spread from human to human mainly in seliva. When somebody who had the plague kissed a preist for instance, the priest would have the plague. In those times, kissing each other on the lips was a sign of gratitude and friendship and love. It was common to kiss each other which didnt make the plague easy to contain instead of spreading it by kissing their loved ones before they died.
