Steady opinion that fleas in cats are transmitted to humans, fully consistent with the truth. To feed these small parasites, human blood is as good as the blood of most domestic animals. It's just not always convenient to eat the blood of a person. But not because his blood is different, but because it is easier for an insect to hide in the fur of a cat or dog.
Other types of fleas are also successfully parasitized on humans, for which the main hosts are animals. From the species to which the fleas belong, and a particular situation, some features of flea transmission to humans depend.
How fleas pass to humans: the process in detail
In the vast majority of cases, the fleas attacking humans are parasitic in domestic animals. For example, fleas in dogs are transmitted to a person directly in the house or aviary where the pet lives.
It is not entirely correct to say that canine or feline fleas are transmitted directly to a person (in other words, to live on a person, such as a cat, a flea can not).
Typically, parasites bite the animal, get drunk blood and jump off his body to find a secluded place for egg laying. Before the feeling of hunger, insects will remain in the litter, in the corners of the room, in piles of rubbish, where their larvae usually develop. And just getting hungry, they again will start to search for a food source. If at this time a person is nearby, they will first attack him.
For the same reason, almost immediately after hitting a person's body, the insect bites it - usually a parasite at this moment urgently needs to be fed.
On a note
In general, the term "transmitted" is not very appropriate with respect to fleas. These insects are temporary parasites, while the word "transmitted" is more often used when describing bacterial or viral infections. Nevertheless, the phrase "fleas are transmitted to humans" is well-established and is used, among other things, in scientific literature.
Only in rare cases, fleas jump from a cat or dog to a person. Often these are the so-called human fleas (Pulex irritans), for which man is the optimal host. However, it is not uncommon for people who simply contact a pet to interact with other animals and move between them without obstacles.
On a note
Dog fleas are transmitted to humans much less often than felines. The latter and are more common in all domestic animals, and in general are more common. It is believed that even a human flea bites a man less often than a feline.
In search of a host, fleas are guided mainly by the smell. Of course, the more a living creature smells, the earlier it will be scented by parasites and the sooner they attack.
In places where there are a lot of insects, there will be a large number of hungry individuals. Accordingly, it is only about such a place to be, as the parasites instantly jump on a new food source. For example, this often happens with hunters next to fox burrows.
Risk factors: where, when and how can you be bitten by fleas
A person can meet fleas almost anywhere. It can be his own house, a picnic in the nature, go hunting or work with any farm animals.
Most often, fleas pass to humans from cats and dogs that live in the house itself. But it's not necessarily these pets: fleas can be transmitted from rats, mice or street cats, found in the front.
Nevertheless, according to statistics, every three of the four domestic sleek pets regularly wear fleas. This means that a domestic cat, a dog, and even rodents with birds can be a source of parasites.
"I somehow do not pay close attention to my dogs. But when I began to bite regularly some insects, and right in the house, I tried to catch them and caught ... fleas. No wonder - both the watchdog have never been poisoned by any chemistry from parasites and have not worn collars. And then the veterinarian also said that it was not dog fleas, but felines. I did not know before whether cat fleas are transmitted to humans, but it turned out that they easily bite, and even do not particularly choose, animals to bite, or people. I had to poison them, first on dogs, then in the whole house. "
The greatest number of insects and almost all the larvae are in places where the animal regularly rests: in a special arena, a crib or a booth. For parasites, the litter in such places is the optimal place for rest, shelter and reproduction.
For example, canine fleas are transmitted to humans almost always near the booth: it is here that the female insects lay eggs, after which they quickly become hungry. Even a person passing by the booth attracts them and becomes another source of food.
Other frequent flea assault sites are:
- natural shelter animals: burrows, nests, hollows. Very risky to be infected and bitten by hunters (especially - when hunting for foxes and badgers in burrows), biologists, loggers.
- Farms and livestock farms. Veterinary farms and rabbit farms are literally teeming with parasites. Even despite the ongoing struggle in these enterprises, there are usually a lot of fleas of different kinds, and their workers are often exposed to bites.
- Typical habitats of small rodents: fields, meadows, glades in the forest, ravines. People themselves often do not notice burrows. And having spread a picnic cover over them, it is very likely that he attracts bloodsuckers to his place of rest.
- Strongly infected fleas.
"I do not let my own home go hunting until he changes clothes in the car, and he does not take things to dry cleaners. Already got these parasites: no matter how it goes into the field in the house, they rain right from him. And then they chew all night. Fleas are very easily transmitted to humans! At one time I constantly poisoned them with all sorts of cans. As it turned out, their husband clings to foxes - there are always a lot of them, and they jump on clothes and bags. "
The main complaints in the services of pest control come from residents of dirty and old apartments and houses, in which parasites live normally and successfully reproduce for years. It is these citizens who often ask whether fleas are transmitted to a person, and wonder why they are constantly bitten in an apartment.
So, it is useful to remember: fleas in cats, dogs, mice and other living creatures are easily transmitted to humans, since they are able to drink the blood of the most diverse warm-blooded organisms, which include humans.
On a note
Very often fleas are carried on clothes, furniture or household appliances in a new room. In this case, the bites will be one-time, but still unpleasant. It is important to destroy all "casual guests" as soon as possible in order to prevent them from multiplying.
What are dangerous for a human fleas: infections and parasites, which carry these insects
The transfer of fleas from a cat to a person and subsequent bites, although painful enough, is not the biggest problem. Scary diseases carried by these parasites.
For example, when cat fleas are transmitted to humans, they can infect it with typhus, anthrax, brucellosis, encephalitis, eggs of numerous helminth species. And rat fleas suffer a plague wand.
It is interesting
It was the rat flea that became the cause of the most terrible epidemic in the history of mankind - the epidemic of the bubonic plague in Europe, which swept away a third of its population. A significant role in the spread of rats, fleas and the disease itself was played by unsanitary conditions, which are generally characteristic of medieval Europe.
Today the plague still exists in nature: its causative agent is present in the body of fleas living in burrows of wild rodents: gerbils, jerboas, hamsters, mice. And the bite of a flea in nature is a kind of lottery: will it be harmless or reward a person with a deadly microorganism ...
How to protect yourself from attack by fleas
Owners of pets who regularly visit their pets on the street need to be constantly on guard. A dog or a cat can, after each walk, bring one or two parasites on the wool, which will be able to multiply quickly in the house and be passed on to the person (in other words, they will actively bite it too).
Therefore, to protect the home from parasites it is necessary:
- to comply with measures to prevent the infection of animals fleas: not to give cats and dogs to communicate with street relatives, regularly check their fur coat, pay attention to any signs of unusual behavior for the pet.
- Immediately fight against parasites if they are found on the pets themselves.
- Keep clean in the room and get rid of those insects that are already present in it. Good means of prevention in the room are branches of wormwood or ammonia added to the water for washing floors.
Such measures will make it possible not to worry that fleas will be transmitted to humans from street animals.
Separately, we should also speak about protection against fleas for those who willy-nilly happens in their places of presence: workers of livestock farms, hunters, employees of zoos and field employees, tourists and travelers. In any condition, a repellent against insects with a substance called DETA is a reliable remedy for fleas.
Works well against mosquitoes in the form of aerosols: in hikes, on excursions or field work, it is enough to spray a solid layer with such a means below the knee to ensure protection not only from fleas, but also from other bloodsucking parasites.
In addition, given that fleas first fall on their feet, it is enough to have tight pants, stuffed into shoes, to ensure themselves protection from fleas while they are in nature. And tourists, who often find themselves in unknown settlements, should be especially diligent in choosing a hotel and not saving on their own health.
