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.

Since the last situation report on the multi-country outbreak of cholera was published on 1 June 2023 (covering data reported until 15 of May), no new country reported a cholera outbreak. In total, 24 countries have reported cases since the beginning of 2023. The WHO African Region remains the most ...affected region with 14 countries reporting cholera cases since the beginning of the year. The overall capacity to respond to the multiple and simultaneous outbreaks continues to be strained due to the global lack of resources, including shortages of the Oral Cholera Vaccine (OCV) and cholera supplies, as well as overstretched public health and medical personnel, who are dealing with multiple parallel disease outbreaks and other health emergencies. Based on the large number of outbreaks and their geographic expansion, as well as a lack of vaccines and other resources, WHO continues to assess the risk at global level as very high.
