“At the present time, I would still propose that a pandemic is imminent because we are seeing transmission to other countries,¡É
¡ÈWe have to expect that phase 6 will be reached. We have to hope that it is not.¡É

Phase 6, the highest level in the organization¡Çs health alert system, is a pandemic. But Dr. Ryan emphasized that the word pandemic describes the geographic spread of a disease, not its severity. There can be a pandemic of a mild disease. The current level, phase 5, means that the disease is spreading in communities — not just within households or in returning travelers — in two countries in one of the World Health Organization¡Çs six regions, in this case the United States and Mexico. To move up to phase 6, community spread would have to occur in at least one other country in another region. ”

¡ÈI think this is a phenomenon we¡Çve been observing over the last few decades,¡É Dr. Ryan said. He noted that some of the major public health threats were of animal origin, including viruses that can wreak havoc when they jump from one species to another.

¡ÈWe have seen in the past that disease can spread from pigs to humans,¡É Dr. Ryan of the W.H.O. said. ¡ÈIt usually dead ends with one or two cases.¡É

But in this case, he said, the disease is now spreading from person to person, with no evidence that pigs were transmitting it to people.

Still, he said, ¡Èthe animal-human interface needs to be watched carefully.¡É
