Monitoreo ambiental de concentración de aire saturado y partículas PM2.5 para la prevención de la Salud Ocupacional en la Ciudad de Potosí a 4000m.s.n.m.

Densely concentrated or saturated air clouds significantly increase the risk of SARS-CoV-2 transmission, particularly in high-altitude urban environments like Potosí (4000m.a.s.l.). Research indicates that such conditions, exceeding climate comfort levels (45% to 70%), elevate the likelihood of COVID-19 contagion through aerosolized particles. The study highlights that symptomatic individuals, as well as those presymptomatic or asymptomatic, can spread the virus via air clouds adhering to clothing or biological systems. Environmental monitoring of saturated air and PM2.5 particles in health facilities—especially dental and emergency settings—revealed critical gaps in ventilation, exacerbating transmission risks during peak occupancy. The findings underscore the need for improved ventilation mechanisms to mitigate aerosol-based transmission in densely populated or poorly ventilated spaces.
