Don't Panic

WHO on verge of declaring H1N1 flu pandemic

The World Health Organization (WHO) is on the verge of declaring the first influenza pandemic in more than 40 years, but wants to ensure countries are well prepared to prevent a panic, its top flu expert said on Tuesday.

Keiji Fukuda, acting WHO assistant director-general, voiced concern at the sustained spread of the new H1N1 strain -- including more than 1,000 cases in Australia -- following major outbreaks in North America, where it emerged in April.

Confirmed community spread in a second region beyond North America would trigger moving to phase 6 -- signifying a full-blown pandemic -- from the current phase 5 on the WHO's 6-level pandemic alert scale.

"The situation has really evolved a lot over the past several days. We are getting really very close to knowing that we are in a pandemic situation, or I think, declaring that we are in a pandemic situation," Fukuda told a teleconference.
