The incidence of Dengue fever in Brazil, post-pandemic COVID-19: Reduction in the number of cases or increase in underreporting? An integrative review

The objective of the present study was to analyze the impact of the COVID-19 pandemic on arbovirus notifications, comparing values obtained in epidemiological bulletins from 2019 to 2022. Thus, noting a large number of possible unreported diseases of these diseases during the pandemic period. This is a quantitative study, intending to establish a relationship between the numbers obtained methodologically through searches of SCIELO articles, journals, epidemiological bulletins, and data from DATASUS and the amount of underreporting identically reported in the study period. The results obtained showed a similarity between the data analyzed in the years 2019 and 2022, however, there was a relevant discontinuity between the intervals of 2020 and 2 021. It is concluded that this fact is about underreporting of cases during the period of greatest incidence of the SARS-CoV-2 virus, influenced by the changes that the pandemic brought to the fore in the spheres of society, politics, economy, and especially the entire area of health, because during the pandemic period, it was identified that the main attention of Brazilian health was focused on solving or reducing the damage caused by a new virus and neglecting health promotion and prevention actions for endemic diseases in our territory, such as dengue.
