En los últimos 200 años varios brotes epidémicos han causado millones de muertos en el mundo, pero, pese a los daños producidos y la alarma generada, no todas las epidemias pueden ser calificadas de pandemias, sino que la OMS reserva esta denominación para las situaciones en que “hay transmisiones de humano a humano en múltiples países de múltiples regiones”.
Las pandemias en el mundo desde el siglo XIX, según datos de la OMS, son las siguientes:
1817- Cólera- La primera “epidemia global” documentada de cólera se extendió del sureste asiático al resto del mundo y, desde entonces, la OMS ha contabilizado siete pandemias.
Hasta 1860 hubo 15 millones de muertos en la India y dos millones en Rusia. La quinta pandemia causó 120.000 fallecidos en España en 1885 y, en la sexta (1899-1923), perdieron la vida 500.000 rusos, 800.000 indios y 200.000 filipinos. La última comenzó en Indonesia en 1961 y se extendió por Asia, Europa y África. Resurgió en Latinoamérica en 1991, con 4.000 muertos.
1824-1840- Viruela- La enfermedad causada por el virus “variola” resurgió en 1824 y se extendió por casi toda Europa, tras causar 827.000 muertos en Rusia entre 1804 y 1810. Un nuevo repunte se registró durante la Guerra Franco-Prusiana (1870-1871), provocando más de medio millón de fallecidos. Sucesivas campañas de vacunación permitieron su erradicación total en 1979.
1855- Peste- Surge en China la tercera pandemia de peste, causada por la bacteria “Yersinia pestis” y transmitida por roedores. Se extendió por el mundo y sólo en la India mató a diez millones de personas hasta fin de siglo. En 1900 resurgió en San Francisco (EEUU) y causó 113 muertos.
Entre los siglos XIV y XVII, la segunda pandemia de peste había diezmado a más del 30% de la población europea (25 millones de muertos). La primera pandemia conocida de la enfermedad fue la “peste Justiniana”, que mató a millones de personas en el Imperio bizantino, entre los siglos VI y VIII.
1918-1919- Gripe Española- Causada por una cepa denominada H1N1, subtipo del virus de la Influenza A. La aglomeración de tropas en la I Guerra Mundial facilitó su expansión. Algunos países, como el Reino Unido, sufrieron nuevas oleadas infecciosas hasta 1920. El total de muertos se estima entre 40 y 50 millones, de ellos 17 millones en la India, 600.000 en EEUU y 200.000 en el Reino Unido.
Se la conoce como “gripe española” porque sólo la prensa de España publicaba noticias al respecto.
1957-1958- Gripe Asiática- Esa cepa de gripe aviar, denominada H2N2, apareció en China en febrero de 1957. Seis meses después se había extendido a todos los continentes. Una segunda oleada de la infección surgió en 1958. Más de un millón de personas murieron.
1968-1969- Gripe de Hong Kong- La cepa del subtipo H3N2 surgió en China en julio de 1968 y pasó a Hong Kong, para después llegar a EEUU, Europa, Sureste Asiático, Japón, Sudamérica y África. Fallecieron entre uno y tres millones de personas, de ellas 30.000 en el Reino Unido.
1982- Sida– Se detectó en San Francisco (EEUU) el primer caso. El VIH ha causado desde entonces 32 millones de muertos y se estima en más de 33 millones las personas infectadas en todo el mundo, principalmente en África subsahariana.
Quedan al margen del término pandemia la enfermedad de Creutzfeldt-Jakob o de las “vacas locas” -diagnosticada por primera vez en Reino Unido en 1985 y cuyo origen fueron piensos contaminados utilizados como alimento del ganado vacuno- y la gripe aviar, enfermedad infecciosa de las aves cuyos primeros casos en humanos se detectaron en 1997. Tampoco fue pandemia el Síndrome Agudo Respiratorio Severo (SARS, neumonía asiática), por el que la OMS declaró la alerta mundial en 2003, tras ser detectado el principal foco en Hong Kong.
