The Emergency Committee held its fourth meeting on 11th June 2009.
The Committee considered available information on transmission of New influenza A (H1N1) in a number of locations in countries in different regions of the World Health Organization, and concluded that the criteria for a pandemic have been met.
Following the advice from the Committee the WHO Director-General decided to raise the level of influenza pandemic alert from the current phase 5 to phase 6. At this early stage, the pandemic can be characterized globally as being moderate in severity.
As previously recommended by the Director-General, countries should not close borders or restrict international traffic and trade.
Countries should assess their specific situation and make a timely transition from focusing national efforts on containment to focusing on mitigation measures, including appropriate non-pharmaceutical interventions.
WHO remains in close dialogue with influenza vaccine manufacturers. It is understood that production of vaccines for seasonal influenza will be completed soon, and that full capacity will be available to ensure the largest possible supply of pandemic vaccine in the months to come.[an error occurred while processing this directive]
