Doctors told dangerous than a mosquito bite

Медики рассказали, чем опасен укус комара

The effects of mosquito saliva on the immune system long enough.

Mosquito bites – not just a nuisance in the form of a long itchy patches, papules. Conducted scientific experiments have proven that even if the saliva of this insect is not infected with pathogenic microorganisms, it has a negative impact on the human immune system. And from the first bite. Research published in the journal PLOS Neglected Tropical Diseases include arguments, which are based on the findings and results of the statements of scientists.

This writes the Chronicle.info with reference to rambler.ru.

According to who and Center for control and disease prevention currently more than one third of the world’s population (and more than 2 billion people) live in areas where mosquito bites are deadly, literally.

Mosquitoes are vectors of diseases such as dengue fever and West Nile virus, malaria, viruses, zika and Chikungunya arbovirus infection, tularemia. Dengue fever is a very dangerous disease. Every year dengue infected from 50 to 528 million people and about 10 000 to 20 000 die. The problem is that the virus has an effect only on humans. Thus, making it impossible to find a vaccine or a cure in the laboratory that experimented on animals.

In particular, by means of such experiments it was proved that the negative impact even a single mosquito bites on immunity and development of allergic response, autoimmune reactions. In case of defeat in mice (and humans too) dramatically increases the number of signal particles inflammation – cytokines. This means that any infection will develop more rapidly, causing a strong inflammation, complications. Also there is activation of T-helper cells, leading to the emergence or worsening of severe allergic reactions. Up to lead to serious consequences and death reactions (e.g., edema angioedema (swelling of the mucous membrane, skin and subcutaneous tissue)).

The effects of mosquito saliva on the immune system long enough – about one week. Currently, the decision to continue studies of the effects of mosquito saliva on the human body.
