Aedes, Polypatogenic Transmitter And Diseases

Aedes, polypatogenic transmitter and diseases

Extensive regions of the world, including the American continent, are in front of a major health problem due.

We refer to the action displayed by Aedes Aegypti, which carries the ethiopathogenic viruses of diseases such as dengue, Zika fever, chikungunya fever, and yellow fever, among other pathologies.

Aedes Aegypti and eventually Aedes Albopictus, is a culícid member of the Stegomyia subgenre within the Aedes genre. It can be recognized by its distinctive white brands in torso and legs;With the exception of what is indicated, its morphological differences with other mosquitoes are light. Originally from Africa, in America, it is presented from the southern USA.UU. even Argentina. Share habitat with Aedes Albopictus, which is moving it in certain areas. Aedes Aegypti activity decreases with a temperature lower than 17 ° C, and below 12 ° C this activity disappears. According to WHO, it is estimated that this kind of mosquito causes 50 million infections and 25,000 deaths per year.

Although Aedes Aegypti can feed at any time, it usually chops more frequently at dawn and sunset. The sites where it can best reproduce are those where there is preferably clean water: containers discovered and abandoned, water sink water or in courtyards, etc.

They are different are the facilitating factors for the multiplication and dispersion of the Aedes spatially. We have indicated very briefly the conducive environment, but there are other elements to take into account, particularly climate change and global facilitator warming so that the weather is tropicalized, even in historically places of temperate or cold climate, facilitating the multiplication of vectors.

And this occurs without other need for ovipositor females that bite man to take blood and thus provide protein to his offspring. The eggs deposited in adequate places for their development until the adult stage will need adequate temperature- which possesses it- and sufficient "tranquility" to fulfill its evolutionary cycle. The adult female will be able to renew the Aedes squad to continue with her spatial invasion. The infestation achieved may be transmitted to its vector offspring, which significantly increases the sanitary problem.

The Aedes aegypti life cycle lasts in total between 7 and 8 days. His life as an adult is up to two months. If in its relatively short flight journe. In this way, despite the short flight of the mosquito, it is displaced in all directions and establishing new spotlights successively, helped by human displacement, which has no limits, determining new epidemic outbreaks or an epidemic for its magnitude.

This species constitutes the main link of the transmission chain. Another constitutes man, because the Aedes female needs for her reproduction of the blood that she obtains through the bite of the human being. If the man is in a viremic phase, the Aedes once it stung, will become the transmitting agent of any of the pathologies recorded. There is no interhuman transmission, except for suspicious cases in Zika virus fever that are being investigated: the transmission of the mother to the son and her relationship with cases of microcephaly, the neurological with Guillain Barré syndrome, the sexual for having isolated virus in semen in semenAs a man, in addition to blood, saliva and urine findings of human beings.

Aedes mosquito pollution, viral circulation- located by traveler transfers- and poor socio-environmental conditions, prevention and eventual control of these pathologies are problematic. It is currently in more than 100 countries, transmitting dengue daily among millions of people and at the same time keeps more than 200 million human beings worldwide around the world.

Strategic failure in prevention and struggle is based on several conditions. While some of them, such as global climate change that is anthropogenic, are difficult but not impossible control, others should be foreseen with the help of a geographic information system. In addition to this, the lack of permanent health education of communities from childhood, creating personal and environmental hygiene habits of the housing environment, taking into account that it is a house and peridomiciliary mosquito.

Another factor of superlative priority is the reinforcement of the peripheral assistance units or in places of border traffic and, subsequently hospitable, for the rapid detection of clinical symptoms by more overlapping than they were.

In summary, prevent and fight dengue, chikungunya fever, zika fever, yellow fever and others, demand a joint and sustained action in the time of the entire community. Once such a pathology penetrates a region, it will take many years to be eradicated. It is not an distressing and transient struggle. It is an adequately scheduled and sustained fight for years to have effective results. Otherwise, even counting today with new vaccines, the results will be painful.
