| | ¿Qué cambios se deben producir para que el H5N1 u otro virus de influenza aviar causen una pandemia?Tim Uyeki
Medical Epidemiologist
Centros para el Control y la Prevención de Enfermedades …there’s no evidence that these viruses have acquired the ability for sustained human to human transmission. That means they have not been able to go from person to person to person to person, continuing on in a sustained manner. There has been transmission from birds to people and, in very rare circumstances, probably limited person to person transmission but then dead-end transmission. So the virus does not have the ability to go further. But there is a possibility that this virus could acquire the properties in the future to allow it to spread much more easily among people and then in a sustained manner from person to person. And that’s what we’re really worried about.
