Seroprevalence of arboviruses in Ecuador: Implications for improved surveillance.

Introduction: Arthropod-borne viruses (arboviruses) cause morbidity and mortality in humans and domestic animals worldwide. The percentage of population immunity or susceptibility to these viruses in Ecuador is unknown.

Objectives: To investigate the proportion of Ecuadorian populations with IgG antibodies (Abs) (past exposure/immunity) and IgM Abs (current exposure) against flaviviruses and alphaviruses and to study the activity of these viruses in Ecuador.

[Genetic analysis of the mutations in HIV-1 infected population in Ecuador].

Background The international recommendations of antiretroviral treatment include resistance tests to guide the treatment regimen in each patient, which is not available on a regular basis in Ecuador. Aim To describe mutations that confer resistance to antiretrovirals in a population of Ecuadorian patients. Methods Plasma samples from 101 HIV-1 patients with failure to antiretroviral therapy, divided into 15 children and 86 adults, were studied with the GS Junior (Roche) and the sequences were analyzed with the DeepChek program.
