LONDON (AP) -- Health experts say evidence from countries which have tried, shows even the strictest containment efforts aren't stopping swine flu.
Even China, which initially claimed success with strict quarantines where entire planeloads of passengers were isolated, now acknowledges swine flu is more widespread that officially reported.
Other nations that have carried out draconian swine flu policies indicate they have little effect.
Ukraine closed all schools and universities, and advised people not to travel and to stay away from public places. Mongolia suspended all bus travel and banned gatherings of more than 40 people. Still, both countries are now facing major swine flu outbreaks.
Argentina, Singapore, Malaysia and Egypt have also enacted radical swine flu prevention measures - and all have been gripped by widespread outbreaks.
