Swine flu has appeared among Venezuela's Yanomami Indians, one of the largest isolated indigenous groups in the Amazon, and a doctor said Wednesday that the virus is suspected in seven deaths, including six infants.

The deaths happened in forest villages near Venezuela's border with Brazil over the past 2 1/2 weeks, said Raidan Bernade, a Venezuelan doctor on a team sent to contain the outbreak and treat the ill.

Bernade told The Associated Press that doctors confirmed one of those who died had swine flu - a 35-year-old Yanomami woman who doctors believe was pregnant.

Six babies, the oldest of whom was about 1 year old, died from similar symptoms, though samples weren't taken in time to confirm it was swine flu, Bernade said by phone from La Esmeralda, a riverside town at the edge of the vast rain forest territory where the Yanomami live.

He said the victims had fever and coughing at first, and suffered complications from pneumonia.

Groups very susceptible to disease
The deaths were reported Wednesday by the London-based indigenous rights group Survival International, which warned that if not properly contained the virus could spread and cause more deaths among people who are particularly susceptible to disease due to their limited contact with the outside world.

Yamilet Mirabal, the government's deputy minister of indigenous affairs for the region, told the AP she was informed of six Yanomami deaths suspected of being due to swine flu. She said the outbreak was detected about three weeks ago and health officials have taken precautions since to prevent the illness from spreading.

Venezuelan President Hugo Chavez acknowledged Tuesday night that the virus reached some indigenous settlements, though he didn't mention the Yanomami or give details.

"Swine flu hasn't gone away... It was detected in an indigenous community," Chavez said in a televised speech. "It's under control now."
