H5N8 spreads to Kuwait as H5N1 returns to Bangladesh

Kuwait has become the latest country to report its first highly pathogenic H5N8 avian influenza outbreak, as it and other avian flu viruses spread to more parts of Europe, with Bangladesh reporting its first H5N1 detections in about a year.

World Health Organization (WHO) Director-General Margaret Chan, MD, MPH, said that, since November, nearly 40 countries have reported fresh outbreaks of highly pathogenic avian flu in wild birds our poultry, adding that rapid expansion and number of cocirculating strains have the WHO on high alert. "I am asking countries to keep a close watch over outbreaks of avian influenza in birds and related human cases," she said. (See related story today.)
