Transmission of SARS-Cov-2 in the current pandemic is assumed to be through small heavy droplets that quickly fall to the ground, do not stray far from the emitter, however episodes of super- spreading in closed environments, and current studies that they show that when speaking, a patient can produce a large number of small drops that are suspended for up to a quarter of an hour, which would make air transmission possible, should be taken into account when restarting activities , improving ventilation and avoiding crowds in closed spaces.

Conociendo que la transmisión del cólera es por la vía fecal-oral, para su control, es necesaria la interrupción de este ciclo, mediante la eliminación adecuada de las heces, evitando de este modo contaminar el agua y los alimentos que ingerimos. Además actualmente se estudia el uso de vacunas.

INTRODUCCIÓN: La infección causada por F. hepática es endémica en el Perú con un creciente numero de áreas endémicas, el reporte de estas es esencial para conocer el impacto de la infección en la población. OBJETIVO: Reportar la tasa de prevalencia de fasciolosis en zonas donde previamente no se habían detectado casos humanos. MATERIAL Y MÉTODOS: Se estudiaron 3 distritos alrededor de la ciudad de Lima: La Chaqui, provincia de Canta; San Lorenzo de Quinti y San Miguel de Sangallaya, provincia de Huarochirí, pertenecientes al departamento de Lima. Se incluyó a niños y adultos jóvenes (menores de 25 años). Cada muestra de heces se analizó mediante la Técnica de Sedimentación Rápida de Lumbreras. RESULTADOS: La prevalencia global por métodos coprológicos en los tres distritos fue 8.6% (n=291); 3.9% (n=102) en La Chaqui, 26.9% (n=27) en San Miguel de Sangallaya, y 8.6% ...

Introduction: enlargement of superficial lymph nodes is a frequent clinical finding which may be among the first evidences of a significant illness or of a specific clinical syndrome.Objective: exploring clinico-pathological relationships in patients consulting for the first time with a clinically detectable lymphadenopathy and no defined diagnosis.Materials and Methods: cross sectional prospective study including patients with clinically detectable lymphadenopathy (nodes over 1 cm in diameter) and often also suspicion of tuberculosis. Lymph node biopsies, fine needle aspirations, and other contributing diagnostic tests were performed. A histopathological classification was structured to arrange the information on the patients and to correlate laboratory findings with clinical ones.Results: patients recruited were 154; 55 (45.5%) out of 70 patients who had a tentative diag...
