No 'sustained' human-to-human transmission of bird flu: WHO
SHANGHAI (AFP) - A World Health Organisation official reiterated Monday there is still no evidence that a new strain of deadly bird flu is passing in a "sustained" fashion from person to person, despite fears some family members may have infected one another.
"Right now we do not see evidence of sustained human-to-human transmission," Mr Keiji Fukuda, the WHO's assistant director-general for health security and environment, said at a press conference.
He added, however, that officials "are always worried whether there could be person-to-person transmission".
Chinese health officials have acknowledged so-called "family clusters", where members of a single family have become infected, but have so far declined to put it down to human-to-human transmission.
