The plight of an eight-year-old Chinese boy with HIV, reportedly ordered to leave his village by 200 petitioners, sparked intense online soul-searching Thursday in a country where discrimination against sufferers remains rife.

The boy's guardian, his grandfather, was among those in southwestern Sichuan province who signed an agreement to expel the child to "protect villagers' health", the Global Times reported.

The newspaper, which has close ties to the ruling Communist Party, said the boy contracted the virus from his mother.

The case has highlighted the stigma attached to the disease in China, where many sufferers face widespread discrimination.

Previous reports said the boy -- who was given the pseudonym Kunkun by Chinese media -- was refused admission to local schools and villagers would avoid contact with him.

"Nobody plays (with me), I play alone," Kunkun said, according to a report Wednesday on the website of the People's Daily newspaper.

The website also said Kunkun was referred to as a "time bomb" in the petition.

"The villagers sympathise with him, he is innocent, and only a small child. But his AIDS is too scary for us," Wang Yishu, party chief of Shufangya village, told the website.

The Global Times said the boy's mother left the family in 2006, while his father "lost contact" after Kunkun's condition was diagnosed.

Kunkun sneaked into a specially-convened meeting held earlier this month by villagers to discuss how they would banish him, the report added.

- 'Ignorance and panic' -

High ranking officials from the township government said "legally speaking" the boy could not be expelled, and that he has the same rights as other villagers, the newspaper said.

"Officials plan to visit the village and speak with the villagers", it added, while the People's Daily website said "ideological work" would be carried out in the village. It was unclear late Thursday whether Kunkun was still in his village.

The case has sparked much debate on China's Twitter-like Sina Weibo, where it was the most widely-discussed topic early Thursday, with many asking how people could be so cold-hearted towards the child.

"Why was he ruthlessly neglected, it is so unfair to him," said a post by one user.

"This is because the Chinese population cannot get enough education, causing ignorance and panic," said another.

Figures released earlier this month by China's National Health and Family Planning Commission showed that a total of 497,000 people in China have been diagnosed with HIV/AIDS since the country's first case in 1985. China has a population of 1.36 billion.

Discrimination against those with the virus remains an issue at schools, hospitals, workplaces and other establishments across the country, a factor that experts say hampers efforts to diagnose and treat it.

Knowledge of HIV/AIDS in worse in poor, rural areas, such as the community Kunkun is from, experts say.

Attempts by authorities to educate these populations about discrimination often fail, a campaigner who would only give his surname as Tang told AFP.

"The publicity campaign is not strong enough to reach the rural areas and villages and that’s why there is more discrimination there," said Tang, a community coordinator at the Kunming office of AIDS advocacy group Aizhixing.

"Personally I don’t think such situations would exist in cities," Tang added. "People in rural areas know little about civil rights and they have a poor sense of the disease.

"We will continue using our network to speak out, meanwhile we hope the government could do more as well."
