Medical experts consulted by iG are alert to ineffective measures and recommend actions to ward off mosquitoes
Aedes aegypti is responsible for the transmission of dengue, the zika virus and chikungunya fever
Skip repellent, wear long clothes, do not let accumulated water. After all, what it is most important when it comes to combat the mosquito Aedes aegypti? There are many questions about which method of prevention is the most effective to get away from that transmits dengue, the zika virus and chikungunya fever.
IG spoke with dermatologist Lilia Guadanhim, member of the Brazilian Society of Dermatology and the infectious disease Jesse Reis Alves, Medical Clinic coordinator Traveler's Emilio Ribas Institute, to address these issues and know what precautions we should have regarding the mosquito.
Repellent
Repellents, according to experts, are very effective in protecting against Aedes aegypti. However, there are shown three types - those that have the IR3535 substances, diethyltoluamide (DEET) or icaridine. "These are the most recommended because there is scientific evidence that they work," says Lilia. However, each has a different concentration, and a specific time duration.
For children ages 6 months and 2 years, it is only indicated the use of IR3535, weaker substance, duration of 4 hours and should be used only once a day. Already repellents with DEET - the most commonly found on the market - last according to the concentration, according to dermatologist ranges from 6% to 15%. "The higher, the greater the length of time," he says. Products with icaridine, for example, have further advantages: they last up to 10 hours in the skin and compared in research efficacy against Aedes aegypti DEET to those with have a better response.
The doctor also warns that the repellent should be passed up to three times a day. "The hotter the time is, the shorter the duration of the product. The indicated is when you pass away, "warns the doctor.
There are three types of repellents that are best known in the market: IR3535, DEET or icaridine
Bracelet citronella
Natural repellents such as citronella and oil andiroba, should not be regarded as a single measure of prevention against mosquito. According to Lilia, they help, but should be used as a supplement. "We do not know, in fact, their duration, but can be 20 minutes to two hours, which is little. In Aedes the proliferation of times you can not rely too much, "he advises.
Fogging and larvicide
The misting larvicide and fogging technique - insecticide spraying - are methods that also have an effect. "These strategies prevent the larvae from becoming adult mosquitoes, which reduces the number of population," explains infectious disease Jesse Reis Alves. It is a measure of control that depends more on the government, but that should be made with individual care of Brazilians.
mosquito nets
For babies, the nets are ideal for protection, and then you do not need the use of a chemical as repellent. Another tip are those that come with insecticide tissues. According to Alves, it is an additional option for those who want to leave the well-protected child.
However, the infectious disease is the warning that for pregnant women - public in which care should be more intense because of zika virus, which is associated with cases of microcephaly - in adults the measure does not have much effect, since it is impossible to stay under a mosquito net during the day, during which the Aedes aegypti bites more.
canvas
The windows on screens should also be used as a care in the most protection against mosquito. They decrease the chance of the bite, but can not be seen as the only preventive measure, since not all cities with networks.
Electric racket
it is misleading to think that electric racket can help fight transmitter of arboviruses. "There is no proven study on this item," emphasizes Alves. The object would be more appropriate to kill in case flies. "The mosquito is much smarter. He sees the movement before, making it harder to capture. "
Use clear and long clothes
Aedes aegypti has photophobia, or aversion to light. So, wear white clothes help but to push it from the body. Moreover, pants and long, baggy blouses are also indicated, as they can cover as much skin.
Avoid water accumulated in plants and potted tire
This is the most effective measure, no doubt. Both infectious disease as a dermatologist warn that despite the use of repellents and other care, do not leave standing water and prevent the proliferation of Aedes aegypti is the ideal way to escape from dengue, the zika virus and chikungunya fever. "Think of eradicating the mosquito is far away, but we need to reduce as much as possible," warns Ahmed.
