Roka commune, Cambodia - Sokha held the small bundle of paper in his trembling hands. Written on each sheet was information that no father should ever have to look upon.

He could barely bring himself to look at those papers again on Saturday.

I want the world to know what happened ... we want help.

- Sokha, Roka commune villager whose wife and three children were diagnosed with HIV

On each was the name of one of his three children: the eldest, a 14-year-old boy; his two normally giggly girls aged 6 and 11, and his 46-year-old wife.

Those papers told him that all had tested positive for HIV.

A doctor who conducted the tests also told Sokha that his newborn infant son was likely infected too.

"I want the world to know what happened," said Sokha, 49, struggling to keep his shaking hand, and inner despair, under control.

"I want the world to know my name, and we want help."

This is the poor rice farming community of Roka in northwestern Cambodia - ground zero for an unexplained mass infection of HIV that has so far seen a reported 140 people, from young children to the elderly, test positive for the deadly virus in the past month.

Unusual suspect

International health organisations, the United Nations programme on HIV/AIDS and Cambodia's Ministry of Health are baffled by the concentration of infections, and a full epidemiological investigation is being launched in this neighbourhood of some 9,000 mostly subsistence farmers.

Though the source of the infections is not yet known, many residents are blaming one man: Yem Chrin, a local medical practitioner who received healthcare training in refugee camps in the 1980s and for the past 20 years has treated a vast array of illnesses for a large number of people in this community.

Yem Chrin was trusted and liked, villagers said, particularly as he allowed the poor families here to pay him what they could, and when they could. Flexible payment made his medical services, even without formal medical training, more popular than getting treatment at state-run health centres.

One of Yem Chrin's daughters said that her father, who was called for questioning by police last week, remains in police custody. She declined to comment further.

"We suspect him because most of the people who received treatment from him are HIV positive," said Sokha, who was the only one in his family to test negative for the virus.

More tests

On Monday, Sokha, his wife, and four children will go for a second round of blood tests at a hospital in Battambang town. They are not optimistic.

"I believe our result is positive and I have very little hope that they will turn negative," said Sokha's wife as she rocked her infant son in a tiny orange hammock at their rickety home of rough wood, bamboo and tin roofing.

"I just don't know what to do," she said, surreptitiously wiping a tear from her eye. "We told the children not to worry. We will have the medicine and they will be OK."

How his children will cope in the long term remains to be seen, Sokha said, explaining that he fears they will be discriminated against, first at school and later in work.

"I don't think they understand it. But we are trying to explain to them," he said.

Strange signs

On the unpaved village path that runs through the nearby village and past Sokha's house, bright yellow signs with evangelical Christian messages in Khmer were mysteriously nailed to trees some months ago.

At the time no one knew who had put up the signs and no one paid much attention to their exhortations, until now.

"The day of God's judgement is approaching."

"The blood of Jesus cleans our sins."

Chief of Roka commune Sim Pov said she is going to take the signs down.

 "I have no idea where the signs came from."

On Saturday, the people of Roka commune received a stream of VIP guests: Cambodia's Interior Minister Sar Kheng and Minister of Health Mam Bun Heng arrived by helicopter in the morning, locals said, and gave out donations of sarongs, bread and noodles.

In the afternoon, several members of a parliamentary commission on public health arrived in cars and addressed several hundred residents, promising to facilitate access to HIV testing and life-preserving antiretroviral treatment.

Mixed messages

Cambodia's Prime Minister Hun Sen was apparently so taken aback by the reports of more than 100 HIV infections in Roka commune that he gave a speech on Thursday saying he simply did not believe it was true, while also announcing a full investigation.

And that may explain why, in a country where the prime minister's word is often considered law, government health workers are at pains to not comment on the number of possible infections - though the Pasteur Institute in Phnom Penh has reportedly confirmed, in a third round of tests, some 140 people in Rokha testing positive for HIV.

Mean Chhivun, director of Cambodia's National Centre for HIV/AIDS, Dermatology and STD, would not comment on Sunday on the number of possible infections as reported by the Pasteur Institute, saying that still further tests need to be conducted and samples are now being sent to the US and South Korea.

Some in Roka are confused by the mixed messages.

"We don't know what the government will do because [the prime minister] said he doesn't believe it," said Sokha, as two neighbours stopped by on Saturday afternoon to offer him support and to console themselves as they had tested positive for HIV earlier this month.

New normal

So, a 45-year-old mother of three, said she was the only one in her family to test positive earlier this month. And father of three, Tha, 38, was the only one infected in his family. In three months time, however, Tha's wife and children must be tested again for the virus.

I just hope that I am well enough to feed my family in the future.

There are so many people now infected with HIV in the area that Tha said it almost feels normal.

"At first I felt dispirited. But, in the few days after I was tested, more and more people found out they were infected, so I felt a little bit normal after that," he said.

 "I just hope that I am well enough to feed my family in the future."

Sokha and his neighbours, one of whom is 80 years old and tested positive for HIV along with his nearly 60-year-old wife, said they want the public to know what has happened, and they want concrete help.

"When parents are infected and fall sick they cannot work, and their children cannot get a good education," Sokha said.

"I appeal to the international community to help our children."
