Arboviral diseases in pediatrics

Objectives: To present the currently available evidence on transmission, clinical, diagnostic methods, treatment, and prevention methods of major arboviruses that occur in childhood. Source of data: Non-systematic review carried out in MEDLINE (PubMed), LILACS (VHL), Scopus, Web of Science, Cochrane, CAPES Portal, and Google Scholar databases for the past five years using the search terms arboviruses, dengue, chikungunya, Zika. Mayaro, and West Nile fever, as well as child, newborn, and adolescent. Synthesis of data: The main characteristic of arboviruses is the fact that part of their replication cycle occurs inside insect vectors, thus being classically transmitted to humans through the bite of mosquitoes (hematophagous arthropods), although non-vector transmission of these viruses is also possible in specific situations. These diseases remain a major public health challenge, due to the lack of specific antiviral treatment, the co-circulation of different arboviruses in endemic/epidemic regions, the lack of effective and safe immunizations for the vast majority of these viruses, and the great difficulty in vector control, especially in large urban centers. Conclusions: Children are especially vulnerable to this group of diseases due to characteristics that facilitate the development of the most severe forms. More detailed knowledge of this group of diseases allows the pediatrician to diagnose them earlier, implement the correct treatment, monitor warning signs for the most severe forms, and establish effective preventive measures.
