Swine flu with 'pandemic potential'


from Associated Press by MARK STEVENSON

The World Health Organization's director-general, Margaret Chan, said the outbreak of the never-before-seen virus is a very serious situation and has "pandemic potential." But she said it is still too early to tell if it would become a pandemic.

"The situation is evolving quickly," Chan said in a telephone news conference in Geneva. "A new disease is by definition poorly understood."

This virus is a mix of human, pig and bird strains that prompted WHO to meet Saturday to consider declaring an international public health emergency — a step that could lead to travel advisories, trade restrictions and border closures. Spokesman Gregory Hartl said a decision would not be made Saturday.

This swine flu and regular flu can have similar symptoms — mostly fever, cough and sore throat, though some of the U.S. victims who recovered also experienced vomiting and diarrhea. But unlike with regular flu, humans don't have natural immunity to a virus that includes animal genes — and new vaccines can take months to bring into use.

But experts at the WHO and the U.S. Centers for Disease Control and Prevention say the nature of this outbreak may make containment impossible. Already, more than 1,000 people have been infected in as many as 14 of Mexico's 32 states, according to daily newspaper El Universal. Tests show 20 people have died of the swine flu, and 48 other deaths were probably due to the same strain.
