Salud pública y agua segura en Latinoamérica: Soluciones sostenibles frente al cambio climático
AI summary Read the abstract
Researchers reviewed the intersection of public health and water quality in Latin America, highlighting how anthropogenic contamination with microplastics, heavy metals, pesticides, and pathogens worsens the regional water crisis and increases gastrointestinal disease burden, emphasizing the need for sustainable purification technologies and equitable access to safe drinking water.
La creciente demanda poblacional y la contaminación antropogénica, que introduce microplásticos, metales pesados, pesticidas y patógenos bacterianos en cuerpos de agua, exacerban la crisis hídrica, reduciendo la disponibilidad y calidad del agua potable. Este escenario incrementa la incidencia de enfermedades gastrointestinales, como hepatitis, cólera y diarrea, responsables de millones de muertes anuales. En América Latina, y particularmente en Ecuador, la problemática se agudiza por sequías prolongadas y la falta de datos actualizados sobre la relación entre salud pública y acceso a agua segura, dificultando la formulación de políticas eficaces. El objetivo de este artículo es presentar un estudio sobre la salud pública y el agua segura en América Latina. Helicobacter pylori, bacteria gramnegativa asociada a patologías gástricas graves, afecta hasta el 70% de la población ecuatoriana, reflejando la alta vulnerabilidad de la región. Este estudio plantea que la baja calidad del agua de consumo humano incrementa significativamente la prevalencia de enfermedades transmitidas por el agua. Por ende, se enfatiza la necesidad de desarrollar e implementar tecnologías sostenibles de purificación, junto con políticas integrales que aseguren un acceso equitativo y continuo a agua potable segura.

AI summary Read the abstract
Researchers assessed the bacteriological water and sand quality of eight recreational beaches along the southern Río de la Plata estuary in Argentina over several years, finding that most beaches exceeded fecal indicator thresholds—with Salmonella and Shigella detected at the most contaminated site—and demonstrating that microplastics in intertidal sediments serve as substrates supporting survival of fecal indicator bacteria.
