La enfermedad producida por el nuevo virus de influenza A (H1N1) continúa extendiéndose en el interior de los países afectados y hacia otros países y el número de casos se ha elevado significativamente. El Dr. Fukuda (OMS) estima que la pandemia afectará el 30 % de la población mundial. El aumento de la capacidad de diagnóstico viral de los países con los nuevos kits diagnósticos de PCR en tiempo real, ha permitido confirmar un mayor númeo de casos. Esta noche se conoció la confirmación del primer caso en la Argentina, en una persona que regresó de México. Brasil por su parte, confirmó sus primeros 4 casos. De esta manera 26 países han confirmado casos y muchos otros tienen casos sospechosos, que se mantienen hospitalizados bajo medidas de aislamiento, entre ellos Venezuela.
