The recent resurgence of arboviruses such as Chikungunya (CHIKV), Zika (ZIKV), Yellow
Fever (YFV), and dengue (DENV), along with the emergence of SARS-CoV-2, has placed
considerable strain on healthcare systems worldwide, including in Brazil. The distribution of
these viral pathogens is shaped by a complex interplay of demographic, environmental, and
social factors, often leading to outbreaks in regions previously unaffected. Brazil, with its
diverse ecosystems and urban expansion, remains particularly vulnerable to such
re-emergences, underscoring the need for enhanced surveillance and response strategies.
Integrating genomic diagnostics with digital disease surveillance offers a powerful framework
for global pathogen monitoring. Real-time sequencing and bioinformatics, combined with
epidemiological data, provide critical insights into how viruses spread and evolve, enabling
timely and effective public health responses across regions.
