The hottest time of the year, between November and April, eventually causes a natural increase in the number of insects. This also applies to the Aedes aegypti mosquito, which causes dengue fever, zika and chikungunya. As a result, local communities in the region are mobilizing to carry out actions aimed at reducing the population of this insect. The actions carried out are based on the PNCD (National Plan for the Fight against Dengue), created in 2002.
The removal of stagnant water points and the application of insecticides in urban areas are the main works carried out. To obtain the location of the points requiring the intervention of the municipalities, the inhabitants can contact the respective administrations and forward the information.
Each municipality has a team specialized in identifying places that may present risks to the health of the population: the agents of endemic diseases. Based on data sent by family health workers, endemic workers carry out inspections of residences, warehouses, vacant lots and commercial establishments to check for endemic outbreaks.
These actions are always carried out in hot weather. As Rio Grande do Sul has a cold winter, the mosquito population usually decreases in the middle of the year. The peak of insect presence generally occurs in April, at the end of the hot season.
All samples from suspected dengue fever cases are sent to LACEN, the National Health Surveillance Center, in Porto Alegre. From there, after verification, the data is transmitted to the cities, presenting the scenario that each town hall has in its municipality.
Good numbers so far
Despite the large number of suspected dengue cases in the regions of Sinos and Paranhana, which are part of the coverage of Jornal Repercussão, Igrejinha and Parobé have confirmed dengue cases.
For this reason, Igrejinha is the municipality that must take the first more intense measures. Parobé has only two confirmed cases. Taquara has the second highest number of suspects, followed by Campo Bom and Sapiranga. Rolante, Riozinho and Nova Hartz are in an extremely controlled situation, without any suspicion.
What is the incidence of possible dengue cases in each municipality
The municipality leads the campaign “All against the dengue mosquito”. The main actions target the Acácias neighborhood, in addition to the Bom Pastor and Cohab neighborhoods. Leaflets, messages in a sound car and vaccinations are distributed in neighborhoods with the application of insecticide. Municipal cemeteries are also vaccinated. There are four endemic agents in the commune, in addition to the community health agents, who sensitize the inhabitants. Of the 100 samples sent for analysis, 67 of them were positive for dengue fever, which puts the town on alert.
Two positive cases of dengue were announced today (10) by the Ministry of Health. There are 30 suspected cases and all are under surveillance. The work of the agents in the homes has intensified, with the aim of eliminating possible mosquito epidemics and collecting the larvae. 12 professionals carry out field work, such as spraying, mainly in the Planalto and 3L districts.
In Sapiranga, the first larval survey of properties was carried out in January and three more rounds of surveys are planned throughout 2022. Today there are two suspected cases and none confirmed. There are nine endemic agents and 18 community agents who carry out actions throughout the commune at the call of the population.
On the 8th, the municipality held a committee to resume prevention activities against the mosquito responsible for dengue, zika and chikungunya. The Contestado district should receive the first actions. To date, no suspected or confirmed cases of dengue fever.
Health surveillance makes visits to strategic points, such as cemeteries, rubber stores, building materials, every 15 days. Two endemic agents carry out activities in all districts. So far, there are no suspected or confirmed cases.
For the first time, larvae of the Aedes aegypti mosquito have been identified in the commune, in the Centro district. There are no suspected or confirmed cases of dengue fever. A decree has been issued by the town hall, prohibiting the use and sale of vases for flowers and decorations without holes. A subcontracted company has been hired to carry out the extermination in the central area.
There are 16 suspected cases and none confirmed, with exams sent to LACEN. In addition to the collection and monitoring actions developed by endemic agents, health agents and health professionals develop orientation and prevention measures, such as team training. The neighborhoods monitored are: Jardim do Prado, Empresa, Sagrada Família and Petrópolis.
So far there are three suspected cases, two in the 25 de Julho neighborhood and one in the Operária neighborhood. Endemic Disease Officers, eight in total, work near suspected dengue fever cases, check the house for mosquito larvae and refer residents. The town hall provides repellents for people suspected of dengue fever.
