Bird flu cases have been "picking up again" in the last few weeks, warns Margaret Chan, the new WHO chief and person responsible for handling the
2003 SARS outbreak in China. "We must not let our guard down. We must maintain our vigilance," cautions Chan.
New WHO chief issues bird flu warning
The new boss of the World Health Organisation has renewed the agency’s warning that the world must keep up its guard against bird flu.
Dr Margaret Chan holds the most prominent United Nations post ever filled by a Chinese national.
Chan said there had been a lull in bird flu infections in recent months, but that cases had begun picking up again in the last few weeks.
After a flurry of reports over Christmas holidays, and yesterday's unconfirmed Hong Kong alert - we haven't seen much about bird flu.
So what does she mean about 'Bird flu cases "picking up again" in the last few weeks'? Is there something going on that we're not being told?
Or is this just responsible caution, recognizing that we're heading into peak flu season?
