aproximadamente 900 personas en 22 pa\u00edses, con una tasa de letalidad del 50%.
En los \u00faltimos a\u00f1os, este virus ha infectado a especies de mam\u00edferos como gatos, perros, visones y zorros,
entre otros. Sin embargo, durante la \u00faltima semana, los medios de comunicaci\u00f3n han informado de las primeras infecciones de ganado
con esta gripe aviar altamente pat\u00f3gena A (IAAP) H5N1 en al menos 6 estados. Las vacas probablemente
contrajeron el virus de aves silvestres infectadas. Parece que s\u00f3lo causa una enfermedad leve en las vacas.<\/p>\n\n\n\n

Caso humano<\/h2>\n\n\n\n

Preocupa el caso de un trabajador de una granja lechera de Texas que dio positivo en la prueba del H5N1 tras
exposici\u00f3n a ganado presumiblemente infectado. Los s\u00edntomas fueron leves y el paciente se est\u00e1 recuperando.
La cuesti\u00f3n es si el virus ha mutado para poder infectar y propagarse entre
humanos para provocar otra pandemia. Para responder a esta pregunta, los CDC estadounidenses han examinado la
secuencias gen\u00e9ticas del virus de Texas. Hab\u00eda peque\u00f1as diferencias entre el esp\u00e9cimen humano
y los recogidos del ganado vacuno, pero ambos mantienen principalmente caracter\u00edsticas gen\u00e9ticas aviares.
En general, esta muestra carece de cambios que har\u00edan que el virus estuviera mejor adaptado para infectar mam\u00edferos.<\/p>\n\n\n\n


Resumen<\/h2>\n\n\n\n

Como resultado de estos primeros estudios, los CDC de EE.UU. consideran que la evaluaci\u00f3n del riesgo para la poblaci\u00f3n en general es insuficiente.

aves u otros animales, incluido el ganado, o a entornos contaminados por aves infectadas o
animales, corren un mayor riesgo de infecci\u00f3n. No obstante, la leche pasteurizada es segura para el consumo, aunque
debe evitarse la leche cruda.
Dada la ausencia de mutaciones u otros signos que favorezcan la transmisi\u00f3n a los humanos, la
