He dengue outbreak continues to rise in the country, as confirmed on Friday night by the Ministry of Health of the Nation, a situation that concerns health authorities. According to the National Epidemiological Bulletin released by the health department weekly, until the epidemiological week 13 of 2023 (that is, until 01/04) 28,235 cases were reported in the country in dengueof which 25,419 acquired the infection in Argentina.
It also reported that there are 14 affected jurisdictions, divided into three regions:
-Central Region (Buenos Aires; Autonomous City of Buenos Aires; Córdoba; Entre Ríos; Santa Fe).
– NEA region (Currents; Formosa; Chaco, Misiones).
– northwest region (Catamarca; Jujuy; La Rioja; Salta; Santiago del Estero and Tucumán).
With regard to the Central region, Santa Fe appears as the most complicated province, with 7,420 cases confirmed and 9780 suspected. Then followed by the Autonomous City of Buenos Aires (CABA) with 3,408 positives and 8,118 suspects. Meanwhile, Córdoba registers 1,390 infected and 2,824 suspects.
In the NOA region, Tucumán stands out, which has 5,132 cases according to the National Ministry of Health, although the local health portfolio already represents twice as many confirmed cases.. Salta follows with 3,820 cases and 7,543 suspects, and Jujuy with 1,932 infected and 3,072 under study.
Lastly, in the NEA region, Chaco is the province with the most cases, which add up to 124 and there are 450 suspects. And it is followed by Corrientes and Formosa with 107 and 106 cases, respectively.
But it’s Information issued by the Ministry of Health of the Nation, through the National Epidemiological Bulletinit is often not updated. By case, recently, the Ministry of Public Health of Chaco reported that, from January 1, 2023 to date, 702 suspected cases of dengue were reported in the province, of which 241 were negative, 396 positive and 118 are under study. . That is, of the 124 cases reported by the Nation, 245 must be added to reach the 396 reported by the provincial health ministry.
The concern of the province of Chaco is that there are 3 dengue serotypes in circulation. Den1 and Den4 joined Den2. This is a risk, as a person bitten by a mosquito with a serotype can develop severe dengue if they are bitten again by another infected with a different serotype. Although the probability is low, possibilities for complications exist: a serious illness can develop and, in some circumstances, cause death from dengue hemorrhagic fever.
“Infection with one of them does not protect against the other serotypes”, recalled the Minister of Health carolina rye this Wednesday in an analysis of the epidemiological situation. “This allows us to suspect that if there is a different one than usual, the risk of re-contagion and complications is greater than what we have been having”, said the minister.
In the same sense, more than 10,000 cases of dengue and seven deaths from the disease transmitted by the mosquito aedes aegypti were recorded in the province of Tucumán since last February, according to the local Ministry of Public Health. These data modify the recent information issued by the Ministry of National Health, which had reported 3 deaths in this province.
“We have already surpassed 10,000 cases of dengue, however, it is likely that this number will increase because there are possibilities of contagion, since there may be patients who have been bitten and the symptoms appear two or three days later”, said the minister. of Health of Tucuman, Luis Medina Ruiz.
The ministry reported the death of two patients diagnosed with dengue, bringing the number of deaths to seven since February, when the first case was confirmed. Medina Ruiz indicated that there are “many consultations, but they are under control”.
Santa Fe officials expressed concern about the dengue outbreak that adds up to 7,661 positives, according to data from the local Ministry of Health. “It’s a disease that’s here to stay,” he said. Jorge Prieto, Secretary of Health of the province. In this sense, he indicated that he expects the curve to continue rising in the coming weeks and expressed concern about the number of hospitalized people, especially children.
So far there are 14 patients hospitalized, including five minors. Four are admitted to the “Orlando Alassia” hospital in the city of Santa Fe and the rest in Rafaela, 120 km west of the provincial capital. “The most serious case we have is that of a six-month-old baby who is in intensive care, with respiratory assistance and a reserved state,” she said. omg the hospital director Osvaldo González Carrillo. And he added: “he developed sepsis as a result of the infection and led to multi-organ failure.”
In Salta, it is estimated that around 10% of the inhabitants of the municipality of General Güemes contracted dengue since the first case was confirmed about two months ago. In this way, it can be seen that between 3,500 and 4,000 people were infected with the disease during the outbreak that affected the province of Salta. For its part, the provincial government reported a few days ago that “7 deaths from this disease have been registered, reported in the departments of General Güemes (3); Saint Martin (1); Oran (2) and Rivadavia (1)”. In this sense, deaths have increased since the publication of the Epidemiological Bulletin of the Ministry of National Health, which recorded 4 deaths in Salta.
“Fortunately, we see that cases are decreasing. We can’t say that the problem is over, but at least we had a week a little calmer than the previous ones, where everything was saturated. Another favorable point that we can rescue is that the serious cases were few, we recorded only three deaths, there are other possible cases, but they could not be determined with certainty”, said Dr. Leandro Abaroa, head of Epidemiology at the Joaquín Castellanos hospital.
Jujuy surpassed 1,400 cases of dengue and there was a drop in hospitalized people. The Provincial Directorate of Health confirmed that they are 331 new cases of dengue in Jujuy. While, 26 people remain hospitalized in public and private health services, in all cases with a favorable prognosis.
He Cordoba’s Ministry of Health reported that another 906 cases of dengue were reported in the last week, bringing the total to 1,781. so far this season, so they urge you to take extreme preventive measures, as well as go to the doctor immediately when symptoms appear. Laura López, director of Epidemiology, said: “In week 12 of this season, a peak of 705 cases was recorded, which surpassed the peak of the dengue epidemic in 2020. That is, in fewer weeks, the number of cases registered for the same time we had in the worst dengue epidemic in the country”.
“It is recalled that, on April 3, it was confirmed the first case of death by dengue in the Province”, they added from the Córdoba health portfolio.
Dengue is a viral disease transmitted by the bite of the mosquito of the genus Aedes, mainly Aedes aegypti. When the mosquito feeds on the blood of a person infected with the dengue virus, it acquires it and after 8 to 12 days is able to transmit it to a healthy person through its bite.
In the case of dengue, the symptoms are fever accompanied by one or more of the following symptoms: pain behind the eyes; Of Head; muscles and joints; nausea and vomiting; intense tiredness; appearance of spots on the skin and itching; bleeding nose and gums.
Before a diagnosis of dengue, it is necessary to follow the instructions of the health personnel and attend follow-up and control appointments. If, at the time the fever subsides or in the following days, any of the symptoms worsen, reappear or new symptoms are detected (breathing difficulty, severe abdominal pain, profuse bleeding from the mucous membranes, irritability due to drowsiness, recurrent vomiting), it is pertinent to make an appointment immediate medical.
Measures to prevent dengue and chikungunya
The main form of transmission of these diseases is through the bite of infected mosquitoes. Therefore, the most important measure to prevent dengue and chikungunya is the elimination of all mosquito breeding sites, that is, all containers that contain water, both inside and around the residences (buckets; basins; drums; pot holders ; drinking fountains; returnable bottles, etc. ).
If the containers cannot be removed because they are used frequently, mosquitoes must be prevented from accessing their interior (cover tanks, cisterns and/or cisterns, for example) or ensure that they do not accumulate water by turning them over; emptying and brushing them frequently or putting them under shelter. It is also advisable to place mosquito nets on the drain grates.
It is worth mentioning that the mosquito adheres its eggs to the walls of the containers, so it is also reinforced that it is fundamental that, in addition to changing the water frequently if the containers that contain it cannot be removed, it is necessary to brush the inside of the walls to remove them.
To avoid mosquito bites, it is recommended to use repellent, always following the package instructions. Likewise, it is suggested to wear clothes with long sleeves and light colors. To protect babies (who cannot use repellent), nets or tulle should be placed over cribs and strollers. Regarding the home, it is important to have mosquito nets on the doors and windows and to use environmental repellents such as tablets, aerosols (interior) or spirals (exterior).
The application of insecticide by fumigation only serves to eliminate adult mosquitoes as long as they come into contact with the insecticide at the time of application, as it has no residual power and does not eliminate immature forms of the mosquito (eggs, larvae and pupae); Therefore, controlling these diseases is not enough if the breeding grounds for new mosquitoes are not eradicated.
Furthermore, fumigation is indicated only in an outbreak situation and under the methodological indications of current national regulations.
