Objective: To describe the impact of the new intervention model implemented by Paraguay across five districts of the Central Region in the last quarter of 2023, consisting of an integrated health services-based strategy to recover coverage with the tracer vaccine (pentavalent until April 2023, hexavalent thereafter) in children under 1 year of age; and the measles, mumps, and rubella (MMR) vaccine for the 1-year-old population.
Methods: Descriptive, cross-sectional study with comparative analysis before (epidemiological weeks [EW] 1 and 34 of 2023) and after (EW35 and EW52 of 2023) the intervention. Three indicators were assessed: a) coverage with all three doses of pentavalent or hexavalent vaccine and first and second doses of MMR; b) productivity, represented by third doses of pentavalent or hexavalent vaccine administered; and c) dropout rates for the pentavalent or hexavalent and MMR vaccines.
Background: COVID-19, caused by the severe acute respiratory syndrome virus type-2 (SARS-CoV-2), was declared a pandemic in March 2020. Seroprevalence studies are useful to estimate the proportion of the population previously infected, quantify the magnitude of transmission, estimate the fatality rate, evaluate the effect of interventions, and estimate the degree of immunity of the population.
Aim: To determine the extension of the infection and the cumulative incidence of age-specific infection, determined by seropositivity in the population of the sanitary regions of Asunción and the Central Department of Paraguay.
In Paraguay, pesticides are the causative agent in 13.7% of poisonings, especially organophosphorus compounds. Such poisoning produces the inhibition of acetylcholinesterase generating three possible clinical conditions: acute poisoning, intermediate syndrome or late neurotoxicity.

It is acquired through contact with major reservoirs like rodents, pets, or the environment contaminated by their urine. In Paraguay, there are no published reports on the seroprevalence of leptospirosis related to work activity.

Objective: To establish the seroprevalence of infection by the dengue virus in a district of the Paraguayan Chaco.
Material And Methods: Cross-sectional study in 418 inhabitants of three villages in the district of Villa Hayes, Paraguay, using a probabilistic household sampling, a questionnaire and blood sampling.
Objective: Report preliminary results of the application of the BONIS system in community tele-epidemiological surveillance in Paraguay.
Methods: A study of viability and implementation carried out in the Family Health Unit located in Bañado Sur in the city of Asunción by the Paraguay River. The system automatically records personal data and symptoms of individuals who make telephone reports, and suspected cases of dengue are classified and prioritized.
