On the third day of the week against national dengue fever, the epidemiological surveillance team of the Ministry of Health (SES) dedicated itself to conducting a rapid index study (Lira) Aedes aegypti, a mosquito spreading dengue fever, zika and chikungunya in the Quadra 38 of Guará II. Lira is a four-year sample survey to identify the radius of mosquito infestation.

A team of 50 people visited about 750 properties. Operations were divided into 15 houses for each agent. “For every thousand properties, we take 400 samples,” explained Hérica Cristina Bassani, director of the Guarán Epidemiological Observatory. The result of the work will be announced soon.

No mosquito larvae were found in the homes visited on the third day of the incident. Plant pots, well lids, pet containers, bottles, cans, nothing went unnoticed by epidemiological factors. “These samples help to know the amount of mosquito infestation Aedes aegypti locality, ”the director explained. “Because the method is sampling, the agent enters the house and passes four. Once this is done, it is possible to know how infected the site is. “

Insecticide spraying against mosquitoes was also part of Guarán’s QE 28 activities

The spread of the dengue mosquito is rapid. The larva grows and becomes an adult in a week. Following the survey, sites of high contamination will be mapped to determine if there is an abandoned house or other environment in the area conducive to the development of insect larvae. If the location has an alignment, it will be revisited to delete it.

Housewife Valdirene Pereira Martins was one of the people who visited the house. He said an inspection of surveillance agents was expected after the pandemic. “When I saw them arrive, I thought it was really good,” he said. The resident said he usually takes every precaution to prevent mosquitoes from breaking out in his home. “People in this area have been careless,” he said. He advocates that the lira be made every two months.

smoke

After the development of the Lira, it was time to inject smoke – a spray system that releases smoke with an insecticide to combat dengue burning – in QE 28 II. Reginaldo Braga, SES Chemical Biological Surveillance Coordinator, said the areas where dengue fever is most prevalent in DF are Sobradinho II, Samambaia and Santa Maria. He is responsible for the smoke distribution team, which consists of 35 cars.

Work in the detection areas for dengue cases always takes place in the early morning and late afternoon, when the mosquito that spreads the disease is activated.
