Fever, joint pain, nausea. The symptoms of eight Columbus players interrupted the alarm in the club sabalero before the suspicion that they could have entered dengue. Finally, the analysis of the players was negative, but the virus transmitted by Aedes aegypti mosquito circulates in Santa Fe, where the team belongs, and there are also cases in Misiones, Formosa, Salta and the city of Buenos Aires, according to an epidemiological warning issued by The National Health Secretary, who warns that positive cases in the first weeks of the year have been recorded "in a sustainable manner" for what it calls for to intensify monitoring. He also notes that the situation of yellow fever in Brazil increases the risk in border areas and for travelers who are not vaccinated.
The newsletter counts 35 positive cases of dengue so far this year: 28 without travel history and 7 similar to people who had moved to other areas before the symptoms began.
Local transmission takes place in three areas: Oran and Tartagal (in Salta) and Santa Fe. There were also isolated cases in Puerto Iguazú (Misiones), Ingeniero Juárez (Formosa) and the City of Buenos Aires. In the capital, according to the last epidemiological bulletin in Buenos Aires, four people came along with the disease: three members of a family having holiday in Brazil and a boy of 15 years without a travel background who presented good development.

"Because of the movement of people, cases can be imported every year. Knowing them is valuable because they are potentially sources of infection to our mosquitoes. What worries us most is when we have original casesbecause with localized transmission that may occur until May, the outbreak begins, "he explains. bugle Tomás Orduna, head of tropical medicine and travelers of Muñiz Hospital.
Viral turnover this year began late compared to the 2016 epidemic, which left 11 dead. On that occasion, at the end of the previous year, there was an important and sustained transmission in Misiones and Formosa. The specialist confirms that the delay in the beginning is not a reason to "sing victory". Ten years ago, another important outbreak began only for this time. "Derg are not possible predictions, except that the extent of outbreaks is strongly linked to the lack of mosquito control. The more there is, the more people will present a clinical picture, "he emphasizes.
In addition to dengue, health authorities urge to "intensify the epidemiological surveillance of cases and increase clinical suspicion" of other arboviruses, including yellow fever in people who have been at risk. That is it Brazil goes through the biggest transfer period: There have already been 12 cases, including six deathsIn the state of San Pablo. And a case was confirmed in Antonina, on the coast of the state of Paraná, where dead monkeys were also found. In the period 2016-2017, 778 cases with 262 deaths were registered in the neighboring country, figures rising in 2017-2018 to 1,376 and 483 deaths.
The situation "marks the beginning of what could be a third wave and the spread of the outbreak to the south-east and south of the country" which configures a increased risk for border regions in Argentina (mainly missions and flows) and for travelers who are not vaccinated, warns the Ministry of Health's report.
Argentina does not have autochthonous cases of yellow fever since 2008. Last year, seven unvaccinated tourists contracted the disease and three of them died. "In the Northeast, the pressure is strong for Brazil, and we need to see what we have done. The vaccine for areas where it is recommended is important," said Orduna. It must be used by Argentinian residents in risk areas; and those who travel to areas with the circulation of the virus – recommended prior medical consultation – preferably 10 days before departure.
Debt in prevention
"We found Aedes aegypti everywhere," says Nicolás Schweigmann, head of the Myquistos Study Group (GEM) of the Faculty of Science at the University of Buenos Aires, whose team conducts observational studies to evaluate the abundance variations of mosquitoes in the city. "In terms of prevention, we are worse than 20 years ago"sorry "I was in March in the northwest region. I found out that the level of containers and hatches is 50% more than in 1998, when it was the first dengue epidemic in the same area, in Tartagal. Something similar is seen in the northeast, in And here in the city of Buenos Aires, the same. "
Schweigmann, who is also a researcher at Conicet, reads the ink on the state's responsibility in the public's consciousness that the elimination of containers and possible breeding grounds of the mosquito reporter is the way to avoid the circulation of the virus; but also through the example of actions of descacharrado in institutions and public properties. "Government after government, it should have been executed a sustained program of cleanliness and environmental management They should have been permanent. Today it does not happen and we are exposed when there is a virus when it comes in now, there is high transmission, "he says.
Orduna is also aimed at active communities and individuals. "If I have potential hatcheries in the patio, my house or terrace will not take them out if it is not me. The state must guide, generate the stimulus to do so," say and exemplify with D-day Brazil, days where descacharrado promoted at domiciliary, neighborhood and state level.
Tips for avoiding reproduction of Aedes aegypti
✔ Avoid stopping containers or waste in places such as terraces, terraces, streets and vacant places where water can accumulate.
✔️Hand patches and gardens wiped out and cover rainfall from roofs.
✔ Remove water from wood holes, rocks, walls, wells, abandoned latrines and fill holes in walls and walls where rainwater can collect.
