No cause for alarm, says WHO

People should not be alarmed following confirmation of the first domestic transmission of A(H1N1) influenza in the Chinese mainland, the World Health Organization (WHO) said on Friday.

"The situation is evolving. We must be mindful as we still do not understand how this will unfold," said Hans Troedsson, WHO's representative in China.

"At the moment, most of the confirmed cases in China are linked to travel. We don't have any evidence of sustained community transmission."
