TL;DR: The described arboviruses associated with acute undifferentiated febrile illness in participating clinics in four countries in South America and detailed epidemiological analysis in Iquitos, Peru are provided to provide a better understanding of the geographic range of arbaviruses in SouthAmerica.

TL;DR: A renewed effort in controlling STIs, especially among MSM groups, could significantly lessen the impact of the HIV epidemic in South America.

TL;DR: Subtype B is the most common subtype in countries lacking injecting drug use (IDU) epidemics, whereas BF recombinants are more common in countries where extensive IDU epidemics have been documented, suggesting the ontogeny of recombinant strains in particular risk groups in South America.

TL;DR: Blood samples from three different clinical groups of chronic Chagas disease patients from Bolivia were analyzed for their circulating parasites lineages using minicircle kinetoplast DNA polymorphism, finding no significant association between Tc types and clinical manifestations of disease.

TL;DR: An ecologic assessment of reservoir species associated with the human disease identified a single hantavirus antibody-positive Oligoryzomys microtis from Mineros and three hant Cavendish antibody- positive Calomys callosus from Concepcion, implicating C. callOSus as the host and Laguna Negra virus as the agent responsible for the HPS case near Concepcions.
