The fifth national dengue epidemic that affects Argentina caused the death of 280 people. Never before since the re-emergence of the virus that causes the infection have so many confirmed cases and so many deaths been recorded in one season.
According to the latest epidemiological bulletin of the National Ministry of Health , the maximum peak of the epidemic was recorded during the week of March 17, with 55,476 cases reported .
Since then, slowly, cases are decreasing in 16 of the 19 jurisdictions in the country that were affected by the epidemic. On the other hand, there are 3 jurisdictions that still have an increase in cases of dengue , the infection transmitted by the bites of female Aedes aegypti mosquitoes .
Epidemiologists from the Health Ministry have reported that the accumulated cases of people with dengue between the last week of July of last year and the week of April 14 represent 3.25 times more than what was registered in the same period of the season. previous (2022/2023) . The cases of this epidemic are also 9.24 times more than what was recorded in the same period of 2019/2020.
After the peak of infections nationwide, in the following weeks differences were recorded that would mark the beginning of a decline in the epidemic. It was found that the following two weeks there were differences of 8% and 6% fewer weekly cases.
What happened with dengue in each region
In the previous season (2022/2023), only 65 deaths from dengue had been recorded in Argentina. In the current season there are already 280 (Getty Images)
The Northeast region is made up of the provinces of Misiones, Formosa, Corrientes and Chaco , in the surveillance system of the Ministry of Health. There were more than 60,883 cases of dengue and 48 deaths this season.
That region of the country was the one that reported dengue cases even in winter for the first time last year. That is, there was a persistent circulation of the virus in the territory. In the fourth week of January there was a peak in cases in the Northeast. Since then Chaco, Misiones and Formosa presented a sustained downward trend.
But in Corrientes a leveling off has been observed since the first week of February, with a slight increase in the last two weeks compared to the previous ones.

In the Central region, which includes the City of Buenos Aires, province of Buenos Aires, Entre Ríos, Santa Fe and Córdoba, a general trend of decreasing the number of cases is observed . Almost all of these provinces have the same pattern.
In this region, 243,968 cases and 171 deaths were recorded from the end of last July to April of this year . The peak of cases occurred in the third week of March, and then there was a decline. “This pattern is similar to that of the provinces of Buenos Aires and Entre Ríos, while in CABA there are two weeks with a lower number of cases than the peak, Córdoba one and Santa Fe presents a pattern of high plateauing,” it was reported in the bulletin.
“In the City of Buenos Aires, dengue cases are decreasing. But there are still people who acquire the infection. Therefore, it is recommended to continue alerting compatible symptoms and taking actions so that mosquito breeding sites are not generated in homes,” said Gabriel Battistella, undersecretary of Primary Care of the Buenos Aires Ministry of Health, in dialogue with Infobae .

In the Northwest region ( Jujuy, Salta, Tucumán, Santiago del Estero, La Rioja, Catamarca ), there was a peak in cases in the week of March 17. In the following three weeks, a high number of cases between 10,300 and 11,700 continued to be recorded.
Catamarca, La Rioja, Santiago del Estero and Tucumán have been at least three weeks below the peak. On the other hand, Salta presented oscillations in the notification of the three weeks following the peak. Jujuy registered an upward trend .
“In Jujuy, last week we exceeded 10,000 weekly cases. You have to take into account the weather conditions from a couple of weeks ago or more. How long does it take for a mosquito to become infectious, for the disease to incubate and for people to attend and for the epidemiological report to be prepared. We are waiting to see what happened with the drop in temperature,” said the doctor in Biology and specialist Mario Linares , from the Institute of Altitude Biology of the National University of Jujuy, to Infobae .

To avoid dengue infections, unused objects that accumulate water should be removed. There may be mosquito eggs and larvae in autumn and winter (Télam)
Days ago, Conicet researcher María Sol De Majo and member of the Mosquito Study Group of the Faculty of Exact and Natural Sciences of the University of Buenos Aires (UBA) recommended these actions to prevent dengue in autumn and winter:
- Clean the walls of containers that may accumulate water with a brush
- Throw boiling water in hard-to-reach places (such as patio grates and balconies)
- Throw away unused containers
- Keep unused containers upside down
- Trying to puncture the tires or throw them away
