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
Oropouche virus (OROV) is an emerging vector-borne arbovirus found in South America that causes Oropouche fever, a febrile infection similar to dengue fever. It has a high epidemic potential, causing illness in over 500,000 cases diagnosed since the virus was first discovered in 1955. Currently, the prevention of human viral infection depends on vaccination, but availability for many viruses is limited, and they are classified as neglected viruses.

Hundreds of millions of people worldwide live under the risk of infections caused by viruses like chikungunya virus (CHIKV, genus Alphavirus), dengue virus (DENV, genus Flavivirus), and zika virus (ZIKV, genus Flavivirus). So far, neither any drug exists against the infection by a single virus, nor against co-infection.
