Ministry of Health warns of rising dengue cases in SC

Santa Catarina already registers more than 500 cases of dengue fever in 2022. The figure sheds light on an alert on care and prevention against the disease. According to the State Department of Health, through the Directorate of Epidemiological Surveillance (DIVE/SC), the highest incidence is in the Western region, which concentrates approximately 87% of cases. natives across the state.

A total of 119 municipalities in Santa Catarina are infested by the Aedes aegypti mosquito, which transmits three diseases: dengue fever, the zika virus and chikungunya. This data represents an increase of 10.2% compared to the same period in 2021, which recorded 108 municipalities in this state.

Another worrying fact: 26 municipalities record the transmission of dengue fever in 2022, four of which are in an epidemic situation, that is to say they record an incidence rate of more than 300 cases of the disease per 100,000 inhabitants. . They are: Seara, Belmonte, Romelândia and Itá.

“To know the risk of transmission of dengue fever, we look at the number of infested municipalities. This tells us where the mosquito is and currently it is spreading across the state. It does not come from outside. Thus, basic preventive care must be constant throughout the year and reinforced especially in this period of transmission of the disease”, warns João Augusto Brancher Fuck, director of DIVE/SC.


Dengue prevention depends on joint action between the government and the population.

“Maintaining basic care, ie eliminating places where water can accumulate, remains the best way to prevent diseases transmitted by Aedes aegypti. Properly disposing of waste, keeping swimming pools and gutters clean, not accumulating rubble, are attitudes that must become routine. Also, don’t forget larger objects, such as water tanks, which need to be covered,” recalls Ivânia Folster, Zoonoses Manager at DIVE/SC.

The State is mobilizing and supporting the municipalities in monitoring and controlling dengue fever. “A DIVE/SC team has been in the West region for two weeks and should stay there for a few more days. The State Department of Health provides technical support to municipalities, helping to identify areas of transmission and with task forces to eliminate mosquito breeding sites, including the application of insecticides, if necessary” , reinforces João Fuck.

Next Wednesday, 23, representatives of SES will be in Chapecó to hold a meeting with the municipal health secretaries and with the technicians of epidemiological and environmental surveillance of the municipalities of the Alto Uruguai Catarinense, Extremo Oeste, Oeste and Xanxerê regions with the aim analyze the epidemiological scenario and list the actions to be taken to prevent the disease.

Dengue fever

Usually, the first manifestation of dengue is a high fever (39° to 40°C) of sudden onset, which lasts from two to seven days, associated with headaches, weakness, pain in the body, joints and eyes. . Body spots are present in 50% of cases, and can affect the face, trunk, arms and legs. Loss of appetite, nausea and vomiting may also be present.

“People who show symptoms of the disease must seek treatment at a health service. Similarly, the healthcare network must be vigilant in identifying these suspicions, by carrying out the clinical management as indicated in the risk classification and the patient management flowchart. The punctual management of suspected cases makes it possible to avoid the aggravation of the situation and even the evolution towards death”, underlines the director.

weekly newsletters

Starting this week, bulletins on Aedes aegypti entomological surveillance situation and epidemiological situation of dengue, chikungunya and zika virus in the state will be issued weekly.

“It is important to highlight that other areas of Santa Catarina have also registered cases of the disease, as well as other municipalities expected to enter an epidemic situation in the coming days. Care must be extended to the whole of the State, and the weekly monitoring of the epidemiological scenario allows the situation to be monitored and helps to guide the measures to be intensified”, emphasizes João Fuck.
