The objective of this study was to identify the presence of pathogenic microorganisms in water supply systems for consumption in human settlements in the city of Pucallpa, Ucayali region. For data collection, the "Protocol of procedures for sampling, preservation, conservation, transport, storage and reception of water samples for human consumption" was used, within the framework of the Quality Management System -NTP ISO/ IEC 17025. Samples from 12 water supply systems were analyzed, with 3 replications per water system. As a result, fecal coliform bacteria were identified in 66% of the systems in ranges from 2 CFU/100 ml to 31 CFU/100 ml, Thermo-tolerant coliforms in 25% of the systems in ranges from 2 CFU/100 ml to 5 CFU. /100 ml, E.coli in 25% of the systems in ranges from 1 CFU/100 ml to 2 CFU/100 ml, Salmonella spp. in 8.3% of the systems in ranges of 1 CFU/100 ml. However, the presence of Legionella spp., Pseudomonas aureginosa and Vibrio Cholerae was not identified in the systems. In 100% of the systems, the presence of Protozoa and Helminths was not identified. It is concluded that 66.6% of the water supply systems evaluated, present pathogenic microorganisms in the water destined for the consumption and use of the population to serve human settlements, therefore, they do not comply with the Maximum Permissible Limits established in the DS.031-2010-DIGESA "Regulation of the quality of water for human consumption".
El año 2020 fue el inicio de la Pandemia del Covid-19, esta fue generado por un virus de la familia de los Corona-V, los primeros brotes masivos se dieron en el país Chino, en el distrito de Wuhan notificado por primera vez como alerta de virus pandémico el 31 de diciembre del 2019. La enfermedad por coronavirus (COVID‑19) es una enfermedad infecciosa provocada por el virus SARS-CoV-2. Esta pandemia tuvo un saldo mortal de 5.78 millones de fallecidos y más de 403 millones casos confirmados. La mayoría de las personas que padecen COVID‑19 sufren síntomas de intensidad leve a moderada y se recuperan sin necesidad de tratamientos especiales. Sin embargo, algunas personas desarrollan casos graves y necesitan atención médica. El virus puede propagarse desde la boca o la nariz de una persona infectada en forma de pequeñas partículas líquidas que expulsa cuando tose, estornuda, habla, canta o respira. Estas partículas pueden ser desde pequeños aerosoles hasta gotitas respiratorias más grandes. Puedes contagiarte de COVID‑19 si respiras cerca de una persona infectada o si tocas una superficie contaminada y, seguidamente, te tocas los ojos, la nariz o la boca. El virus se propaga más fácilmente en espacios interiores o en aglomeraciones de personas.
