简要总结
Exanthematous fevers are a global public health problem. The spread of arboviruses due to various factors, including climate change, has resulted in major epidemics such as the one that occurred in Brazil in 2024, representing an extremely concerning scenario from both epidemiological and healthcare perspectives. In addition to this, the reemergence of childhood exanthematous diseases in several countries, including Brazil, is alarming and occurs due to declining vaccination coverage and increased migratory movements. These diseases present overlapping clinical symptoms, and their differential diagnosis is often challenging, which, in a context of dengue and Chikungunya epidemics like the current one, may lead to underreporting of diseases such as measles and rubella. This project aims to build a prospective registry of the occurrence of dengue, Chikungunya, measles, and rubella in various healthcare centers in Brazil, in order to better understand the epidemiological scenario, identify clinical variables associated with different diagnoses, and describe healthcare bottlenecks that may hinder proper reporting and identification of these diseases.
