by The mosquito invasion that affects the AMBA is currently carried out by the one that transmits Western Equine Encephalitis (WEE)although there is also a presence in the area of the mosquito that produces dengueso much so that the first ones have already been registered seven indigenous cases in five communes of the City of Buenos Aires.
The mosquito that transmits WEE is the Aedes albifasciatus, which proliferates due to flooding resulting from the intense rains characteristic of this summer. Its habitat is large expanses of green spaces.
The mosquito that transmits dengue is unfortunately better known. he Aedes aegypti and it reproduces in home environments, generally when there is stagnant water in containers. Unlike the “flood mosquito”, prevention through debris removal in this case is key.
Another difference between one mosquito and another is behavior, which includes the way they sting, that is, the impact and the mark they leave when they go in search of blood. The albifasciatus bite is much stronger than that of the aegypti, which is usually more subtle in his work. This can result in the former’s wheal being more prominent.
Why does this difference occur in the way they sting? The mosquito that transmits WEE is wild and its adaptation has been developed based on its main targets and power supplies: birds and hard-skinned mammals, such as horses. For this reason, experts explain, when they attack people they leave a more recognizable mark because of the intensity. And it is more likely that as a result of that force they will be able to bite through clothing.
The dengue mosquito, on the other hand, is domestic. As he is used to stinging Humanshas developed much more behavior “civilized” and stealthy than the other species, in terms of flight characteristics on approach, also taking into account that the body they carry is somewhat larger than that of the field ones. At the same time, they bite with less power because they have not needed to develop that skill to survive.
The physical characteristics of mosquitoes are recognizable: the flood mosquito has a color. brown uniform and the urban one has a black body with white stripes. But since the vast majority of the time it is impossible to catch the mosquito red-handed, a good way to identify the author’s first and last name is the impact it leaves on the skin.
The result is usually more reddish and hive-like when the wild mosquito bites, although sometimes it may depend on the characteristics and physical reaction of each person. That is, if she is allergic or if she has already contaminated the “crime” scene with her nails through the scratching.
Then, the eventual infectious consequences They are obviously another test to identify the mosquito from the bite, since each species mentioned here is responsible for transmitting a different virus. But of course, statistically the vast majority of people who are bitten are not infected.
In urban areas, furthermore, it is least likely that the Aedes albifasciatus mosquito transmits WEE because the source of the infection is rural animals. In fact, according to the latest National Epidemiological Bulletin, in the last week there were a confirmed case in the City of Buenos Aires but with a history associated with rurality in an area of Buenos Aires where infections are being identified.
In total, throughout the country the number of cases of WEE in humans has increased in the last week from 12 to 21 confirmedof a total of 91 suspects in 11 provinces.
Regarding dengue, from week 47 (mid-November) to date there have already been 10 deaths. And since the beginning of December they add 4,703 casesof which 96 percent have been native.
