The tiger mosquito: the risk of viral transmission

The tiger mosquito is the main vector of several viral diseases: dengue, zika and chikungunya (tropical diseases, common in the Caribbean and Reunion and resulting in high fevers, sometimes fatal). In pregnant women, the zika virus could be responsible for micro-encephalias (very small head) that babies.

Alone, the mosquito can not transmit the disease. He is only a vector. It is, when it stings an infected person and it will bite another healthy person, that there is a risk of transmission of the disease, a risk of viral transmission.

In fact, the tiger mosquito does not work like a dirty needle would do for other viruses. The process is more complex: the mosquito absorbs the blood of an infected person, the virus then develops in the insect and returns with its saliva. Knowing that the transmission of the virus can be done only during the first 7 days when the clinical signs are visible, it is understood that the surveillance and the reporting of the affected people, are essential.

How to protect yourself?

What concerns health professionals is to avoid as much as possible the meeting between a tiger mosquito and a person with dengue or chykungunya. This is why, when a person feels affected by the disease, the first prevention is to isolate it, to protect it from mosquitoes (by mosquito nets, repellents ...).

Thus, during the seven days when the carrier of the disease presents a risk of transmission, he must not meet a tiger mosquito.

Surveillance and control systems are therefore regularly activated by the Ministry of Health. Sites at risk are targeted for cleaning: highway areas, tire storage, ports, airports.

Entomological surveillance campaigns are carried out in the at-risk departments where the mosquito has sometimes been seen without it being really implanted.

Patients suffering from dengue, chykungunya, zyka are immediately reported. Surveys are conducted near their homes.

Mosquito control campaigns can also be conducted, as was the case in the Hérault, for example.

Information is systematically given to travelers in endemic areas to protect themselves and others.

The genome

The genome is the set of genes of each living being. This genetic material consists of DNA (deoxyribonucleic acid), a long polymer formed of 4 types of nucleotides (symbolized by 4 letters of the alphabet) whose precise sequence in a specific order forms the genes. It was in 2000 that researchers decoded the human genome, which they identified each of the letters of this alphabet which is linked together

The genome: What is a karyotype?

A karyotype is the study of the chromosomes of an organism. For this, cells are removed and the cell division is stopped at a stage that allows to observe the chromosomes well. Modern techniques make it possible to see if genetic alterations exist and which ones. The study of chromosomes is quite often used
