Vol. 31, ACS-1, 1 February 2005

On page 4, under Infanrix™-IPV/Hib [GlaxoSmithKline (GSK) Inc.] section, it incorrectly states:

The poliovirus strains, as in Pentacel™, propageted in human diploid cells and inactivated.

Instead it should read:

The poliovirus strains, as in Pediacel™, are grown in Vero monkey kidney cell lines.

International Notes

Influenza in the world
September 2005 - January 2006

Between September 2005 and January 2006, influenza activity was generally mild and was low compared with the same period in recent years. In North America and Asia, influenza activity began in October and increased in December in some countries, while in Europe, activity remained low throughout this period.

Influenze A(H1N1) circulated at low level in many countries. Most A(H1N1) isolates were closely related to A/New Caledonia/20/99. No A(H1N2) detection was reported. Influenza A(H3N2) viruses were associated with outbreaks in several countries. Whereas the majority of A(H3N2) viruses were closely related to A/California/7/2004, the current varrine reference virus, an increasing proportion of recent viruses were more closely related to A/Wisconsin/67/2005. Influenza B viruses were isolated from sporadic cases in many countries. The majority of recent virus isolates were antigenically similar to B/Malaysia/2506/2004, the vaccine reference virus.

A total of 50 countries/areas, including five from Africa, 10 from the Americas, 11 from Asia, 21 from Europe and three from Oceania, reported influenza activity between September 2005 and January 2006. Of the 50 countries/area, four reported regional/widespread outbreaks associated with influenza A(H1) and A(H3N2) viruses.

One influenza A(H1) outbreak was reported in Tunisia.

Outbreaks associated with A(H3N2) viruses were reported in Canada, Japan and the United States.

Influenza B outbreaks were not reported.

Between September 2005 and January 2006, 61 human cases of influenza A(H5N1) were associated with outbreaks of highly pathogenic avian influenza A(H5N1) in poultry in China, Indonesia, Iraq, Thailand, Turkey and Viet Nam. Since December 2003, a total number of 173 human cases have been confirmed from seven countries. The World Health Organization (WHO) influenza pandemic preparedness level remains unchanged at Phase 3.
