Are human fleas to be feared?
Hello, I am 36 years old and have a rather unusual question. I think I have been bitten by a flea, I don’t know if this is possible, but I found information that there is such a species as the human flea. I came back from a trip, the conditions were not the best, I came back with bites on my back and both hands. Is the human flea dangerous? What exactly does the human flea look like?
The bites are in the form of red lesions, some are pink and slightly convex, I am experiencing itching and I know I can’t scratch these lesions to prevent an infection. I don’t know what to do, should I go to the doctor to see if it is really a flea bite? Are there over-the-counter remedies available at the pharmacy that will help me relieve the symptoms of the bite?
I’m wondering if I should get specialized blood tests because I think the human flea can transmit diseases. I also don’t know how long the flea bite marks last on the body. I would really appreciate an honest answer as I don’t really know what I should do, the lesions have lasted for quite a long time.
Doctor explains if human fleas are dangerous
Dear lady, the human flea is an external parasite that lives on humans, but also on dogs, cats, rats or foxes. As for the size of the human flea, the female reaches about 2.5-3.5 mm in length and the male about 2.0-2.5 mm. The adult form of the human f lea feeds on blood, so many red lesions are found in the host, which are small and can be flat as well as convex.
In addition, after the sting there is a strong itching caused by the irritating secretion produced by the flea. Skin lesions should not be scratched due to the possibility of bacterial superinfection, which may require antibiotic therapy. In terms of pathogenic significance, the human flea can carry a variety of bacteria, including Yersinia pestis causing plague, Francisella tularensis causing tularemia, and the well-known Staphylococcus aureus. Unfortunately, I am unable to determine if the skin lesions on your body are related to human fleas, so you should see a doctor.
By the time of your visit you may be using anti-allergic medications to relieve the itching, both oral and topical will be indicated. About 3 days after the flea bite, the lesions should subside. After contact with fleas self-observation is recommended, in general no tests for diseases spread by fleas are performed. Of course nothing stands in the way to do such tests. In case of doubts, besides visiting your family doctor I suggest you to contact a doctor of infectious diseases.
