The outcome in 2011 lira (Quick Survey Index infestation by Aedes aegypti) revealed that 48 Brazilian cities are at risk for the occurrence of an outbreak of dengue. The map, which identifies where are concentrated the breeding places of Aedes aegypti mosquito was conducted between the months of October and November this year, is conducted by the Ministry of Health, in partnership with local health departments.

Earlier on Monday (5), in presenting the results of LIRA 2011, the Health Minister, Alexandre Padilha, explained that the study is a kind of photography that allows the Ministry of Health know the dengue situation in the country . "The cities that are in an alert situation, can not let their guard down: instead, should intensify their actions. The municipalities in cases of low risk can migrate to a major epidemic, "he said.
"The Lira is an essential tool to guide the actions of dengue control, because it allows the local health managers anticipate the actions of prevention," added the minister. He said the survey data do not mean that the situation can not be reversed. "A certain municipality, which presents a risk situation, you can change that with the intensification of the measures in the areas of greatest risk," said Alexandre Padilha.
The Ministry of Health will closely monitor the evolution of dengue in the states and municipalities. The map revealed that 4.6 million people live in areas at risk of dengue epidemic. "Beyond the conventional surveillance system, we, from now, with the Observatory of Dengue, another tool that will help us in monitoring the disease through social networks," said the minister.
The new assessment also points out that 236 cities are on alert (with index between 1% and 3.9%) and 277 have satisfactory rate below 1%.
The cities at risk, including three capital - Rio Branco (AC), Porto Velho (RO), Cuiab? (MT) - are located in 16 Brazilian states: four in the North, seven in the Northeast, three in the Southeast, one in Midwest and South Region (see table below).
ALERT
Among the capitals in a state of alert, stand out Salvador, infestation rate of 3.5%, Recife (3.1), Bethlehem (2.2), San Luis (1.6%) and Aracaju (1 5%). Fortaleza and Natal, which last year were on the alert, began to situation as satisfactory, with infestation rates of 0.9 and 0.8, respectively.
This year, the lira was extended to 561 municipalities, an increase of 53% compared to 2010, when it was performed in 427 cities. The survey will be done at least three times a year. The measure aims to empower communities to know the places most critical.
The Secretary of Health Surveillance, Ministry of Health, Jarbas Barbosa, explained that the Lira municipal act allows managers to more effectively for the elimination of mosquito breeding sites identified in the most common. This action, he said, can also be performed successfully by the community.
"To remove the foci of the mosquito is no need to use technology. It takes only the adoption of simple measures that anyone can use in their homes, "said the secretary, during the presentation of the results of LIRA 2011.
Livestock and reduction of cases
The Ministry of Health is handing over $ 90 million for the qualification of prevention and control of dengue fever to 989 municipalities. The selected cities will sign a membership with a commitment to carry out epidemiological surveillance, and measures aimed at assisting patients.
This morning, the minister drew attention to the breeding of larvae of the mosquito, primarily in the Northeast and Midwest. "In the Northeast, more than 70% of outbreaks are concentrated in water reservoirs and in the Midwest more than 40%," noted the minister.
By the end of November, there were 742,364 reported suspected cases of dengue across the country. Compared with the same period last year, there was a reduction of 25%. From January to November 2010 were 985,720 registered cases of suspected disease. The South, Southeast and Midwest also observed a decrease in dengue fever: The biggest reduction - 77% - was registered in the Central West. There were 211,695 cases in 2010 from 48,524 in 2011.

VIRAL MOVEMENT
Dengue virus has four serotypes (DENV 1, DENV 2, DENV 3 and DENV 4). The virological surveillance activities in 2011, highlighting the predominance of DENV circulation in a country. It has been found, however, an important circulation of DENV types 2 and DENV 4. This scenario, coupled with environmental conditions, which enable the maintenance of the mosquito Aedes aegypti, alert to the possibility of persistent transmission of the virus at high levels in the summer of 2012.
