The new rapid index survey of Aedes aegypti (Liraa), carried out this week – between 7 and 11 March – has brought yet another alert to the population of Umuarama: the number of properties with larvae of the mosquito which transmits the Dengue has increased 300% from January this year, from 0.7% to 2.8% according to the Environmental Health Surveillance Service.
2,161 properties were visited and in 60 the inspectors found larvae.
The acceptable, according to health authorities, is up to 1%. A building infestation between 1% and 3.9% – the case of Umuarama, today – is considered medium risk for dengue fever incidence and above 4% is high risk. No hoppers were found in the properties visited in only four of the 18 regions that have health units in the urban area. The index is not calculated in the districts.
The most serious situation is that of Jardim São Cristóvão, where an infestation was detected in 9.2% of the properties, followed by Guarani/Anchieta (7.4%) and Conjunto Sonho Meu (6.5%). In 11 other health facilities, the presence of mosquito larvae varied between 0.4% and 4.3% of properties visited by endemic agents from the Municipal Health Department.
By location, the most critical condition is in the São Paulo Church area, where the building infestation rate has reached 16%. Praça dos Xetá was close to that (15%), followed by Parque San Marino (12%), Jardim Império do Sol (11%), Jardim Nova América and Escola Paulo Freire (10% each) and Zone 2 (9.1% infestation).
In ten other localities, the index was also well above the acceptable level (between 5.5% and 7.7%) and in 15 districts of the city, it varied between 1.3% and 4%. In 29 other locations, no dengue mosquito outbreaks were found.
With the incidence of heat and rain showers in recent days, even isolated, it is time to intensify care. It is necessary for the population to carry out routine inspections in the yard, in order to eliminate all containers that can accumulate standing water, such as buckets, bins, tires, cans, potted plants, old toys and recyclable materials.
“Everything must be tidy and protected from the rain so that the mosquito has trouble breeding. Dengue cases are increasing in Umuarama. This week alone, 36 more people have been registered with dengue,” warned environmental surveillance coordinator Renata Luzia Ferreira.
