Dengue epidemic causes eight deaths and affects 16 municipalities in SC

Santa Catarina recorded the eighth death from dengue this year, the highest number of deaths recorded by the disease in the history of the state, surpassing in just over three months the entire year of 2021, when there were seven deaths.

According to Dive (Directorate of Epidemiological Surveillance) of the State Health Department, this number of victims could double, since there are still eight other deaths under suspicion and under investigation.

Six of the deaths from dengue were in municipalities in the West region: two in Chapecó, two in Seara, one in Romelândia and another in Itá. In addition to one death in Criciúma, in the south of the state and another in Ascurra, in the Itajaí Valley. Another three regions of concern are health agencies: Greater Florianópolis, Vale do Itajaí and Northeast.

Dive reported that 16 municipalities are experiencing a dengue epidemic, all in the West. The characterization of an epidemic occurs through the relationship between the number of confirmed cases and the number of inhabitants. The level of epidemic transmission is when the incidence rate is greater than 300 cases per 100,000 inhabitants.

The interim Secretary of State for Health, Alexandre Lencina Fagundes, reported that the secretariat is on alert. This Wednesday (06), he and a team visited Chapecó, worried about the seriousness of the situation in the region. “Health is on alert, making this dialogue and giving support to the municipalities”, he said.

Fagundes highlighted that the State will make a series of confrontations with the disease. It provides for the return of situation rooms in the municipalities, surveillance actions and people management, that is, breaking the biological cycle of the mosquito that transmits dengue (Aedes aegypti) and the appropriate clinical management in cases of contamination of patients.

“The objective is to stop the transmission of the virus. We will carry out task forces to break the biological cycle of the mosquito. We have a forecast of rain and sun for the next 40 days and this becomes an environment conducive to the proliferation of the mosquito”, said the secretary.
