Article Synopsis
- * A cross-sectional approach was used, enrolling 1,138 individuals over nearly two years, with tests revealing a 20% prevalence of IgM antibodies and a remarkable 97.5% for IgG antibodies against HSV-1.
- * The presence of HSV-1 DNA was confirmed in over a quarter of individuals with positive IgM results, indicating a significant silent prevalence of the virus within this community, particularly in individuals with certain urinary and genital symptoms.

Article Synopsis
- * Females exhibited a higher prevalence of HSV-2 antibodies (59.5%) compared to males (49%), with significant associations found between antibody presence and various health issues like urinary problems and genital wounds.
- * The seroprevalence of HSV-2 in this community was significantly higher than in the general adult Brazilian population, suggesting a need for targeted health interventions to address contributing factors and improve public health policies.

Background: Herpesvirus transmission between humans and non-human primate (NHP) can occur through contact scratches with lesions, infected saliva, and mainly through contaminated food. Therefore, cross-infection can lead to severe illness or even death for both the animal and human. In 2017, during the yellow fever (YF) outbreak in Brazil, species of the New World Primates (NWP) from Rio de Janeiro state, tested negative for yellow fever virus (YFV) detection.

To determine the time-lag effect of meteorological factors on the relative risk (RR) of dengue incidence in Coronel Fabriciano city, Brazil, we applied a distributed lag nonlinear model, a modeling framework that can simultaneously represent nonlinear exposure-response dependencies and delayed effects, to establish the association between dengue incidence and weather predictors. The weekly number of notified dengue cases during the period 2004-2010 was used for analysis. When considering the rainfall, the highest RR (1.
