The U.N. health agency on Monday raised to 107 the confirmed number of people who have died from the H5N1 strain of bird flu, adding two Egyptian women who died last month.

The World Health Organization said the total number of confirmed human infections since the current outbreak began in 2003 has reached 190. Virtually all the individuals were exposed to the disease in poultry.

WHO said four people previously announced by the Egyptian Health Ministry as H5N1 positive all were confirmed to have had bird flu at a WHO laboratory in Britain.

Two women in their 30s died; the other two patients have been discharged from hospital, WHO said. The agency said it is still awaiting results on samples from at least three more Egyptians to have tested positive for bird flu in local laboratories.
