Santa Catarina recorded Eighth death from dengue fever this yearwhich is the largest number of deaths recorded by the disease in the history of the state, as it exceeded in just over three months the whole of 2021, when there were seven deaths.
According to Dive (Directorate of Epidemiological Surveillance) of the state Department of Health, this number of casualties could double, as eight more deaths are still suspected and under investigation.
Six dengue deaths occurred in municipalities of the Western Region: two in Chapeco, two in Ceará, one in Rumlandia, and one in Eta. Plus one death in Criciúma in the south of the state and another death in Ascurra in the Itajaí Valley. Three other areas of concern are health agencies: Greater Florianópolis, Valle de Itajay and the Northeast.
Dive reports that 16 municipalities have a dengue epidemic, all in the West. The characterization of an epidemic occurs through the relationship between the number of confirmed cases and the population. The level of transmission of an epidemic is when the infection rate is greater than 300 cases per 100,000 population.
The Interim Minister of State for Health, Alexandre Linsina Fagundes, reported that the secretariat is on alert. On Wednesday (06), he and a team visited Chapeco, concerned about the seriousness of the situation in the area. “Health is on alert, this dialogue and support for the municipalities,” he said.
Vagondis confirmed that the state will conduct a series of confrontations with the disease. It provides for the reinstatement of municipal case rooms, monitoring and personnel management procedures, ie breaking the biological cycle of the mosquitoes that transmit dengue (Aedes aegypti) and appropriate clinical management in cases of contamination of patients.
The goal is to stop the transmission of the virus. We will implement task forces to break the biological cycle of mosquitoes. “We have forecasts of rain and sun for the next 40 days, and this will become a favorable environment for the spread of mosquitoes,” the minister said.
