GENEVA - Some cases of swine flu have been reported among people displaced by conflict and flooding in southern Philippines' Mindanao island, the World Health Organization said Friday.

"We're... seeing reported cases of H1N1 among the IDP communities there," said Paul Garwood, spokesman for the WHO.

Garwood could not specify the number of A(H1N1) infections among the 400,000 displaced people in the region, but said there were "several."

The WHO said recent flooding had exacerbated the situation of people who had been displaced by conflict which broke out in August 2008 between government troops and separatists.

"Health services in the camps are now being provided by understaffed and poorly supplied mobile teams," said the WHO.

The UN health agency was seeking 914,176 dollars to fund the setting up of a local office in Mindanao, the supply of medication as well as the recruitment of new health staff.

The Moro Islamic Liberation Front has been engaged in a separatist campaign in the southern Philippines since 1978. Five years ago it signed a cease-fire but talks collapsed in August 2008. Both sides have recently taken steps to resume the talks.
