Article Synopsis
- Chikungunya virus (CHIKV) has been spreading variably across Brazil, and its impact in São José do Rio Preto (SJdRP) is studied to understand the low incidence of reported cases, despite the potential for underdiagnosis due to overlapping symptoms with other viruses like dengue.
- A study involving 341 asymptomatic individuals over four years showed an increase in anti-CHIKV IgG seroconversion from 0.35% to 2.3%, and 4.4% of dengue-suspected individuals tested positive for anti-CHIKV IgM during a 2019 outbreak.
- Genomic analysis confirmed the presence of the ECSA genotype of CHIKV in SJd
Enterovirus (EV) is commonly associated with central nervous system (CNS) syndromes. Recently, gastroenteric viruses, including rotavirus (RVA), human astrovirus (HAstV), and norovirus (NoV), have also been associated with CNS neurological disorders. The aim of the present study was to investigate the presence of EV, RVA, HAst, and NoV associated to CNS infections with undiagnosed etiology in Northwest region of São Paulo State, Brazil, and to conduct the molecular characterization of the positive samples detected.
