Data from the Ministry of Health indicate that 12 cities in the Paraíba Valley and Brindisi region are "in a state of alert" against dengue, zika and chikungunya. The badessment is based on the new rapid survey of Aedes aegypti infestation rates (LIRAa) of 2018.
According to the Ministry of Health, cities whose index indicates between 1 and 3.9 are on alert in case of outbreak of diseases caused by the mosquito. This means that for every 100 homes surveyed, 3 had larval infestations.
The cities in alert for infestation levels are:
Taubaté, the largest city in the region on this list, had an index of 2. The city recorded 57 cases of dengue fever in November of this year, compared to 63 at the same time last year. Seven people have had chikungunya this year and six in 2017. The city has had no cases of zika.
The Taubaté Town Hall said that it acted in homes, condominiums and schools. In addition, he has planned a mosquito trawler in the Continental area next week.
In the valley and Bragantna region, Lhabela and Vargem recorded the highest statistical degradation rates (3.4%).
In the state of São Paulo, 208 municipalities are on alert and 42 are at risk of epidemics. Another 388 are in satisfactory condition and five other municipalities have used a trap, which is used when mosquito infestation is very low or non-existent – the case of Campos do Jordão.
Across the country, 5,358 municipalities, or 96.2% of the cities, carried out some sort of surveillance of the mosquito transmitting these diseases, ie 5,013 per infestation survey (LIRAa / LIA) and 345 by trap.
The Ministry of Health recommends that municipalities implement LIRAa at least four times a year. In January 2017, the case file made the survey by the municipalities regarding the entomological investigation into the Aedes aegypti infestation and the sending of information to the state secretaries to the health, as well as the Ministry of Health.
