    01/11/2020 - 21:48 Santiago

    The head of epidemiological surveillance of the Ministry of Public Health of Missions, José Gutiérrez, confirmed that there have been cases of dengue in three locations in the province, "all are of the DEN 1 serotype," he said.

    In this way, it was confirmed that the disease is already present in northern Argentina. In addition, the places are tourist, so they recommend caution to Santiago residents who are heading to that area.

    "We have three locations where the positives are confirmed, which are of type DEN 1, which are in Andresito, Puerto Iguazú and in the capital department," Gutierrez said.

    Currently, "we are in a containment and not a mitigation stage," he said, which means that "all patients are going to be admitted, notified and made the corresponding laboratory," he said.

    "We are a tourist province and we ask people to come, but we ask for responsibility, that they take care of themselves, that they see the schedules that are dangerous, that they are placed repellent and that when they return they do not self-medicate, that they make a consultation," concluded the chief of Epidemiological Surveillance.

    Dengue: cases have already been registered in 15 provinces of the country and in the Federal Capital there are 165 infected
    In the province of Buenos Aires, meanwhile, 152 infected were reported so far this year. Buenos Aires Health Minister Daniel Gollan said the virus "is here to stay"
    February 29, 2020

    While the world is in turmoil for the expansion of the coronavirus, in Argentina health authorities fight another epidemiological emergency: a new outbreak of dengue that has already claimed two lives in the province of Buenos Aires.

    According to the latest report of the Ministry of Health of the Nation, the virus transmitted by the mosquito aedes aegypti already circulates in 15 provinces of the country between native and imported cases.

    The official survey covers the period from week 31 of 2019 until February 17. During that period, "4089 cases with suspected dengue or other arboviruses were notified to the National Health Surveillance System, of which 748 were confirmed and probable," as detailed.

    Of those 748, 474 imported cases were counted (people who have traveled to areas with viral circulation or under investigation), between confirmed and probable, in 15 Argentine provinces. While the remaining 274 cases correspond to patients with no travel history. So far, dengue was registered in areas with native viral circulation in 11 provinces (Buenos Aires, Córdoba, Santa Fe, Entre Ríos, Chaco, Corrientes, Formosa, Misiones, Salta, Jujuy and La Rioja).

    In total, in the province of Buenos Aires 152 cases have been confirmed so far this year, of which 77% correspond to people who had traveled to Bolivia, Colombia, Misiones, Formosa and Salta before starting with the symptoms.

    The latest newsletter issued by the provincial Ministry of Health reported that the outbreak expanded to 12 of the 135 Buenos Aires municipalities: La Matanza, Tres de Febrero, Quilmes, General San Martin, Lomas de Zamora, Vicente López, Lanús, Malvinas Argentinas, Avellaneda , La Plata, San Miguel and Merlo.

    The head of the health portfolio, Daniel Gollan, said that dengue "is here to stay" and that "the mosquito is everywhere and not only in the most peripheral neighborhoods of cities." "Everything is being done so that the coronavirus does not enter, but dengue is in Argentina," said the minister in statements to the TN channel. He added: “The less breeding sites, the less dengue we are going to have. It is not that we are going to eliminate it, dengue is already to stay in the Americas and in the southern part of the continent. ”

    On February 17, the first case of a person who died as a result of the virus was known. It was a 73-year-old man, a native of the Buenos Aires Avellaneda party who died at the Italian Hospital in the city of Buenos Aires. According to the sources to which Infobae had access, the subject presented a very weak health condition at the time of infection.

    The other fatal victim is a 69-year-old woman who lost her life last Thursday at Penna Hospital. A native of the town of Temperley, in the city of Lomas de Zamora, she had arrived from Paraguay on February 21, with fever and abdominal pain.

        More than 14 thousand cases of dengue were registered in the country
        According to the Epidemiological Bulletin, 39,573 cases with suspicion of this disease or other arboviruses were reported in Argentine territory, of which the amount cited was confirmed or probable for Aedes aegypti.

        The Ministry of Health of the Nation reported this Thursday that between August 2019 and the second week of April, 14,237 cases of dengue were confirmed and revealed that in the last month the most affected localities were the city and the province of Buenos Aires, Santa Fe , Salta, Jujuy and Chaco.

        According to the Epidemiological Bulletin, 39,573 cases with suspected dengue or other arboviruses were reported in Argentina, of which 14,237 were confirmed or probable for dengue.

        The cumulative number of notifications so far for that 2019/2020 season "is between 7 and 8 times higher than that reported in the 2018/2019 and 2017/2018 seasons, respectively, for the same period," the last Bulletin highlighted on this day. Epidemiological published by the Ministry of Health.

        Of the 14,237 confirmed cases, 11,297 did not present a travel history record in 17 provinces, while 2,945 cases had been traveling in areas with viral circulation outside the jurisdiction of residence, the Epidemiological Bulletin noted.

        In addition, it was reported that the presence of 3 serotypes was registered in different places in the country: 62% corresponded to DEN-1, 36% to DEN-4 and 2% DEN-2.

        According to the document, the curve of cases shows an increase from the first week of January of this year and in particular from February at the expense of all the provinces in outbreak, with the exception of Misiones that registered an outbreak since November 2019.

        In the last three epidemiological weeks, the jurisdictions that reported the highest number of cases were the City of Buenos Aires, with 3,449 and 37 cases under investigation; the provinces of Buenos Aires, with 2,565 cases and 385 under investigation; Santa Fe, 1580 cases with 114 under investigation; Salta, with 744 and 164 under investigation; Jujuy with 1077 cases and 100 under investigation, in Catarmarca there are 279, Chaco with 761 and 19 under investigation, and Tucumán 670 and three deaths.

        The Bulletin indicated that 319 localities were affected by dengue outbreaks, a number that includes several Buenos Aires communes.

        In the current season, according to the document, 25 people died with suspected dengue were registered until April 4, 2020.

          Scientists warn that the dengue mosquito adapted to survive the cold

          Saturday, April 25, 2020

          It is a mechanism called "diapause" that, until now, has never been described in this species.

          "In other mosquito species, the environmental signal that determines whether the eggs will want to hatch or not is the photoperiod - the number of hours of light experienced by the mothers of the eggs - as it is a much more reliable indicator than the temperature, which is fluctuating and could confuse bugs, " Dr. Sylvia Fischer, a CONICET researcher and member of the study , told the CTyS-UNLaM Agency.

          In warm and tropical regions, habitats of the Aedes aegypti par excellence, the temperature seems to be a sufficient indicator for the mosquito's eggs to become larvae and follow the cycle until they become adults. However, in Buenos Aires and other regions of the country, this observation does not always seem to be true.

          For example, if you live several days in a row with more than 12ºC in the winter, this context could incite the hatching of the eggs, but if the temperature then drops, the larvae would die after hours, losing a large number of futures adults in that "miscalculation".

          Apparently, the females of Aedes aegypti found, at least locally, a strategy that this species did not develop anywhere else in the world -the diapause-and that when it was disclosed to the international scientific community, it caused the astonishment of many, and some resistance as well.

          "A very large scientific bibliography maintains that Aedes aegypti does not have a diapause, and this allowed us to assert that the mosquito was not going to be able to cross certain climatic limits," said Fischer, adding that, however, "in Argentina, the vector is progressing in its distribution and it has been found both in downtown Buenos Aires and in La Pampa, Mendoza, San Juan, Neuquén and Río Negro. "

          Although the Aedes seems to have found new strategies against the cold of the Argentine territory, the greatest challenge faces it when the neighbors organize and eliminate the hatcheries from their houses
          . Faced with that, they assured, there is no adaptation that is worth it. (Source: CTYS Agency) ./ Telefé Noticias

            Thursday, May 7th 2020 - 10:42 UTC
            In Argentina since August last year until April 2020 the notifications system has reported 52,594 suspected cases of dengue, Zica, Chicungunya and Yellow fever.

            Argentina officially has 5.208 COVID 19 confirmed cases with a death toll of 273 since the pandemic broke out. However the country is suffering from even more acute disease infection, the mosquito-transmitted dengue, with some 25.000 confirmed cases, and of which 5.601 in the last three weeks.

            According to the latest Epidemiology report from the Health ministry, “the average notifications in the last three weeks was 5.601, which is almost ten times the average of the same three weeks in the 2018/19 season”. The report adds that the number of suspected cases is similar to that of the previous season, but since week 12 of 2020, at the end of March, the peak soared.

            In other words, the accumulated number of notifications between week 31 of 2019 and week 16 of 2020 is six to eight times greater than in the 2018/19 and 2017/18 seasons respectively for the same period of time.

            In Argentina since August last year until April 2020 the notifications system has reported 52,594 suspected cases of dengue, Zica, Chicungunya and Yellow fever....

              Dengue: there are already 32,223 cases and 24 deaths in Argentina
              According to figures from the last report of the Ministry of Health, of the 24 deceased, 8 were women, 16 men, with ages between 14 and 87 years and a median age of 48. Regarding the previous report, just 10 days ago, 6,459 were added. cases

              With all the efforts made by the health authorities to contain the situation due to the COVID-19 coronavirus, the dengue outbreak in Argentina is increasingly concerned. The figures are overwhelming: a total of 32,223 cases were recorded from the end of July 2019 until last May 2, according to what was reported in the last Epidemiological Bulletin of the Ministry of Health. 1,764 cases are still under investigation. The latest report on May 5 had yielded 25,764 confirmed, representing an increase of 6,459 cases in the last 10 days.

              Three serotypes of the virus circulate that, during that period, killed 24 people.

              The National Health Surveillance System studies the health situation in relation to seasonal dengue. The new season of analysis of the information for the epidemiological characterization began on July 28 of last year, therefore the official data published this Friday extends from that date to May 2 last. 420 localities throughout the country were affected by dengue outbreaks so far.

              In relation to the 24 people who died from dengue in this period, the Epidemiological Bulletin specified that there are 11 other deaths that are under investigation by suspects. The deaths were of eight women and 16 men, with ages between 14 and 87 years and a median of 48 years.

              In the city of Buenos Aires (CABA) the cases amount to 6,896, since the beginning of this year, but they assure that the seasonal trend in decline continues, as in the last four weeks, as reported this Saturday by the Buenos Aires Ministry of Health .

              The national bulletin detailed that Jujuy registers the highest accumulated incidence of the period with 366.3 cases per 100,000 inhabitants, followed by Misiones, Salta and La Rioja with rates of 283.9; 216.2 and 204, respectively.

              "However, the greatest contribution of cases is concentrated in the Central Region with 14,704 autochthonous cases followed by the NOA Region with 11,303," the health report specified.

              Likewise, it is noted that the highest number of cases of the season was registered between weeks 10 and 16 (March and April 2020) at the expense of the Central region.

              "In recent weeks, NEA's contribution to the total number of cases in the country is minimal," said the official survey.

              In this region of the country, the first notifications began the first week of September 2019, with increases and peaks in January and March, especially due to infections in Misiones "where a gradual decline is seen."

              The same situation occurred in another of the northeast provinces, since Corrientes shows decreases in cases and neighboring Chaco reported "similar values" between March and April.

              Meanwhile, in the NOA "an increase was observed" from the last week of January "sustained over time" until mid-March, registering the largest number of cases between April 12 and 18, a situation that "is decreasing".

              The document details that since the beginning of April, "Jujuy, Salta and Tucumán are already the provinces that contribute the greatest number of cases to the total for the region."

              In the Center region, the increase was evident in January with two maximum peaks in March "coinciding with the highest number of cases registered for the City and the province of Buenos Aires."

              Córdoba showed a sustained number in March and April, while Santa Fe recorded two peaks in the same period and in Entre Ríos it occurred in March.

              Dengue is a viral infection transmitted by the bite of infected females of mosquitoes of the genus Aedes aegypti and there are four serotypes of the virus. Three circulate in Argentina: 69% of the cases corresponded to DEN-1; 29% to DEN-4 and 2% to DEN-2.

              This disease is not transmitted from person to person, or through objects or breast milk. The symptoms, according to the World Health Organization (WHO), are high fever (40 ºC), accompanied by two of the following symptoms: very severe headache, pain behind the eyeballs, muscle and joint pain, nausea, vomiting, enlarged lymph nodes, or rash.

              "As much as the pandemic occupies our head at the moment, dengue is a very serious issue and we do not have to neglect it. In Argentina we are in times, therefore, we must insist on care, on waste, on fumigating , in mowing the grass. No one can say that this is a choice of one disease over another. In fact, there have been cases in which both diseases have been added, "said doctor Lautaro de Vedia, an infectious medicine doctor, in dialogue with Infobae (MN 70.640), former president of the Argentine Society of Infectious Diseases.

              For her part, the infectious medicine doctor Gabriela Piovano (MN 85,555), considered that “the situation has exploded in recent years as a result of two situations that occurred almost simultaneously: on the one hand, climate change, which was occurring with the arrival of high temperatures of more than 30 degrees for longer periods of time than 10 years ago, which caused that the larvae could breed in our environment and this gave rise to autochthonous cases ”.

              On the other hand, according to the specialist, "this worsened after the environmental control and mosquito-borne diseases program was deactivated in the previous government." "There were personnel assigned to work in the outbreak places that were no longer there and both issues led to the situation being quite complicated today."
