In this Friday, Feb. 18, 2011 file photo, Indian health workers carry killed ducks to burry them at the R.K. Nagar Government Duck Farm in Agartala in the remote northeastern state of Tripura, India. An official says around 4.000 birds have been culled at a government-run duck farm in the state after some poultry tested positive for a deadly strain of bird flu that can potentially be fatal for humans.

Not again. According to the World Health Organization, avian influenza has killed 20 people in China, after two more died since the outbreak began in late March. There are 102 cases currently, 70 of which are being hospitalized. "Until the source of infection has been identified, it is expected that there will be further cases of human infection with the virus in China," WHO said in a statement.
