The infectologist Eduardo Lopez He stated this Thursday that “there are many fewer cases” of dengue than those detected in 2024 at this same time of year. The specialist pointed out that in principle they are focused on the northeast of the country, “especially in Formosa and Chaco,” as he detailed.
“In the area that covers the City of Buenos Aires and in general the entire province there are many fewer cases,” said López, although he warned that we must wait for the evolution of infections because “December was not a month of real heat” which did not facilitate the reproduction of the mosquito that is the vector of the disease.
There are fewer cases of dengue than a year ago
The infectious disease specialist told Radio Rivadavia that The delay in high temperatures benefited the low number of cases since “the female Aedes aegypti mosquito below 12 degrees has much lower viability and does not have as much biting capacity.”
“We have to wait to see what is going to happen, especially in February and March which are the months with the highest increase in infections. However, we have fewer cases and this is encouraging news,” he warned. Regarding vaccination, he expressed concern because “adolescents are not being vaccinated as hard as they should,” but indicated that “it is a safe vaccine and with “high protection” to avoid hospitalization and serious cases.
For her part, the infectious disease specialist and Conicet specialist Victoria Micieli He said that “temperatures have not been very favorable until now” for the reproduction of Aedes aegypti, but warned that starting in January “the hottest and rainy seasons begin that favor the procreation of the vector.”
“February and March are always the period of mosquito abundance where we have to be more attentive, taking care of ourselves and using the means of protection we have,” Micieli said in statements to Radio Splendid. For the specialist, “the vaccine is the most recommended tool for prevention” and she pointed out that, if a person had a first case of dengue, “It is recommended that you get vaccinated and, if you have not had it, you should consult.
Finally, regarding the effectiveness of repellents and the mosquito’s resistance to them, he stated that “it is not scientifically proven that there is resistance to repellents”and stated that “all the approved formulas are different and they all prove to be effective.”
“The resistance that is being studied is not to repellents but to the insecticides that are used (against mosquitoes), which are pyrethroids, with which they are commonly fumigated. In laboratory studies we have detected, starting in 2018, resistance to insecticides but not repellents,” he emphasized.
