H7N9 sickens three more in China

Two of China's provinces—Anhui and Guangdong—reported a total of three new H7N9 avian influenza cases today, according to separate health department reports.

Anhui province reported two of the case-patients, a 48-year-old man from Ma'anshan and a 75-year-old man from Wuhu, according to a provincial report translated and posted by FluTrackers, an infectious disease news message board. Both are in critical condition and had been exposed to live poultry before they got sick.

The two infections are Anhui province's first H7N9 cases in the third wave of illnesses that started in October.

Guangdong province's patient is a 58-year-old man from Zhaoqing who is hospitalized in critical condition, according to FluTrackers' translation of an official provincial report.

The three new cases lift the global H7N9 total to 611, according to a case list maintained by FluTrackers.

H3N2 dominates global flu picture, but H1N1 and B make headway

Flu activity is rising in many parts of the world, including Europe, Mongolia, South Korea, and parts of tropical Asia such as southern China and India, the WHO said yesterday in an update.

Though H3N2 is still the dominant strain globally, the 2009 H1N1 virus has been responsible for a sharp increase in activity in India and has been increasing in other countries such as Jordan, Morocco, and Tunisia, as well as in southwestern Europe, the WHO said. Infections from influenza B are increasing in some parts of the world, such as the United States and Europe.

In North America, flu activity seems to have peaked in the United States and Canada, but flu detections are increasing in Mexico. The WHO said flu activity also appears to have peaked in parts of eastern Asia, including northern China and Japan.

In Europe, many countries are reporting high flu activity, with a higher mortality in people age 65 and older than seen in the previous four flu seasons. Southern China's flu activity, and that of Hong Kong, is also increasing, with a mix of H3N2 and influenza B responsible for most of the activity in that part of China and Hong Kong seeing H3N2 dominate.

Flu detections in Africa remained low, but some areas are reporting some influenza B activity.

In Southern Hemisphere countries, flu activity is at interseasonal levels, the WHO said.

Globally, 81% of flu detections are influenza A, with 87.5% of the subtyped "A" strains being the H3N2 virus. Of the influenza B strains, 97.3% belonged to the Yamagata lineage.
