Background: The introduction of Zika and chikungunya to dengue hyperendemic regions increased interest in better understanding characteristics of these infections. We conducted a cohort study in Mexico to evaluate the natural history of Zika infection. We describe here the frequency of Zika, chikungunya and dengue virus infections immediately after Zika introduction in Mexico, and baseline characteristics of participants for each type of infection.

- This study investigated the prevalence of Human Pegivirus (HPgV) in Mexico among blood donors and HIV-infected individuals, revealing that 2.98% of blood donors and 33% of HIV patients tested positive for HPgV.
- Researchers analyzed nearly 8,000 serum samples using advanced PCR methods and found two prevalent HPgV genotypes, with viral loads showing distinct low and high patterns that affected HIV progression.
- The study concluded that high HPgV viremia may offer a beneficial effect on HIV infection markers, indicating the need for further exploration of the underlying mechanisms driving different HPgV replication patterns.
