The government of the state of Paraná has announced that it is in a situation of dengue epidemic thanks to the increase in the number of cases of the disease. More than 80,000 notifications and five deaths have been recorded since August 2021. The bulletin published this Tuesday (19) recorded 14,964 new notifications compared to the previous week. The document also informs that 365 municipalities have reported cases, of which 287 have had confirmations. In one week, there was a 39.86% increase in confirmed cases, from 16,560 to 23,161. The West and North Macroregions concentrate the greatest number of cases. The situation is critical despite the fact that Paraná has a sustainable biotechnology, developed in the state, which has been able to eradicate the disease in the city of Ortigueira.
The Natural Vector Control project developed by Forrest Brasil Tecnologia, with the work of Brazilian and Israeli scientists, has been carried out in the municipality in collaboration with the Klabin company, since November 2020. In one year, the number of larvae has been reduced by 90 %. the vital ones found in the field. In this epidemiological year there were no cases of dengue in the municipality, while the neighboring municipalities, such as Tibagi, are experiencing an epidemic.
The method is based on TIE technology – use of Sterile Insect – in which mosquitoes are released massively. Sterile males mate with wild females, which stop reproducing, causing an immediate reduction in mosquito infestation and the spread of diseases such as Dengue, Chikungunya, Zika and Yellow Fever. The study is recognized by the international scientific community, being published in the Journal of Infectious Diseases, a peer-reviewed medical journal, published by Oxford University Press on behalf of the Infectious Diseases Society of America, the main reference in the area. The Paraná Department of Health also recognizes and approves the technology, with willingness to be applied in different regions of the state.
During the rainy season, the multiplication danger of Aedes aegypti is enormous. This is because, after about 15 hours of laying, mosquito eggs are able to withstand long periods of low humidity, and can stay dry for up to 450 days. “Vector control tools that use technology and innovation are fundamental, since the conventional tools used have not been effective and without control diseases are spreading more and more” – explains the technical director of Forrest, Lisiane Poncio.
