El desarrollo de inmunidad a un patógeno por infección natural es un proceso de varias etapas que suele producirse a lo largo de una o dos semanas. El organismo responde a una infección vírica de forma inmediata a través de una respuesta innata no específ...ica, en la que los macrófagos, los neutrófilos y las células dendríticas frenan el avance del virus y pueden incluso evitar que este provoque síntomas. A esta respuesta no específica le sigue una respuesta adaptativa en la que el organismo genera anticuerpos que se unen específicamente al virus. Estos anticuerpos son las proteínas denominadas inmunoglobulinas. El organismo también genera linfocitos T que reconocen y eliminan las células infectadas por el virus: es lo que se conoce como inmunidad celular. Esta respuesta adaptativa combinada puede eliminar el virus del organismo y, si la respuesta es suficientemente intensa, puede evitar el agravamiento de la enfermedad o la reinfección por el mismo virus. Este proceso se mide a menudo a través de la presencia de anticuerpos en la sangre.

Improvements in water sanitation and hygiene (WASH) and wastewater management in all sectors are critical elements of preventing infections and reducing the spread of antimicrobial resistance (AMR) as identified in the Global Action Plan to combat AMR. Yet, at present, WASH and wastewater management... actors and improvement actions are under-represented in AMR multi-stakeholder platforms and national action plans (NAPs). This WHO/FAO/OIE technical brief on WASH and wastewater management to reduce the spread of AMR provides a summary of evidence and rationale for WASH and wastewater actions within AMR NAPs and sector specific policy to combat AMR. Evidence and actions are presented in the domains of; coordination and leadership, households and communities, health care facilities, animal and plant production, manufacturing of antimicrobials, and surveillance and research.
