Hymenolepis nana (HN), llamada tenia enana, es una infección intestinal frecuente en niños de todo el mundo. Los humanos adquieren la enfermedad por transmisión fecal-oral al ingerir alimentos o agua con huevos infecciosos presentes en las heces de roedores infectados. Es importante determinar los factores que facilitan la persistencia de HN, para incorporarlos en las decisiones de prevención y control. El presente trabajo es de tipo transversal analítico y tuvo como objetivo evaluar la infección y factores de riesgo en 14761 niños de 2 a 15 años durante un estudio de investigación a gran escala en el norte de Perú. Examinamos muestras de heces usando la técnica de sedimentación en tubo para el diagnóstico coprológico de HN. Encontramos que 1124 de 14761 niños (7,61 %) tenían infección por HN. Pudimos evidenciar una asociación entre la infección por HN y el abastecimie...

Peru had the second-highest number of COVID-19 cases in Latin America. After the first wave, Peru registered more than 900,000 cases of COVID-19 and more than 36,000 confirmed deaths from the disease. Tumbes, a border area with poor sanitation and not enough water, had the fifth highest death rate. The cross-sectional analytic study aimed: a) to assess seroprevalence of COVID-19 after the first wave; b) to assess sociodemographic determinants and symptoms associated with a positive COVID-19 antibody lateral flow test.

During the first wave, COVID-19 had devastating effects on developing countries like Peru, which reported more than 900,000 cases of the disease and more than 36,000 confirmed deaths from it. The informal settlements are counted in COVID-19 regional statistics, but they are very different from the rest of the region in terms of sanitation, access to water and sewage, housing conditions, and others. To make good decisions about public health, it is important to understand how the disease is spread in informal settlements. We did an observational, cross-sectional study in Puerto Pizarro, a remote port village in Tumbes, from November 11, 2020, to November 30, 2020, to assess the seroprevalence of COVID-19 after the first wave, as well as the sociodemographic factors and symptoms linked to a positive COVID-19 antibody lateral flow test. 1391 people older than 2 years old were given census a...
