The survey in the folder, coordinated by the Health Surveillance Secretariat (SVS), gathers probable cases of dengue from January 2 to May 7 registered in the Internet Notification Disease Information System (Sinan Online), where previously discarded diagnoses are excluded. .

According to doctors and scientists, dengue is characterized as a cyclical disease, which does not act together or is homogeneous throughout the country. Therefore, epidemics usually occur every three or five years. Greater movement after restriction against Covid-19 is one of the factors leading to the increase in cases.

No vaccine is available on a large scale in Brazil, since the vaccination agent can be applied only to people who already have the disease and have antibodies to minimize the risk of adverse events. In addition, doses are limited in private laboratories. In this sense, the best strategy is to eliminate stagnant water. In addition to high temperatures and rainfall, the country has found ideal breeding grounds for Aedes aegypti, mosquitoes that transmit dengue and other arboviruses, such as chikungunya and zika.

The ministry recommends checking for possible breeding sites, such as roofs, gutters, pools, bottles and hoses, and keeping trash closed to combat the disease. Water storage containers should be covered with potted plants should be sanded to prevent mosquitoes from laying eggs. The folder says that it is important to seek medical attention in case of suspicion of the disease and that there are treatments available in the Unified Health System (SUS).
