Two workers who were poisoned through exposure to toxic chemicals at a Suzhou factory of a main supplier to Apple, were terrified to see relapses in their diseases after they went for medical checks at a Shanghai hospital.

However, when they went back to Suzhou from Shanghai for medical treatment, the workers were turned away by a Suzhou hospital as the doctors would not approve any diagnoses done by other hospitals.

The two poisoned workers, Liu Xiaojian, 26, and Liu Ruiyong, 31, told Shanghai Daily that they came to Shanghai last Sunday, at their own expense, for a health check after they felt their conditions deteriorating.

"It gave us a terrible feeling that the old disease was coming again," said Liu Xiaojian.

Liu Xiaojian said it was only nine months since they were told that their diseases had been successfully cured.

But diagnosis reports by Shanghai Huadong Hospital showed that the two workers were suffering nerve damages to their arms and legs. The reports said that they had to be hospitalized immediately.

Liu Xiaojian said they decided to get medical treatment back in Suzhou because Huadong Hospital could not provide two vacant beds as it was full of patients.

But the Suzhou No. 5 People's Hospital refused to accept them as patients as doctors told them that the Shanghai hospital's diagnosis reports did not prove they were ill.

"I don't understand. The two hospitals have similar qualifications, so why does one deny the other's diagnosis?" asked Liu Xiaojian.

He said that they have taken further health checks at the Suzhou hospital, but the results came out as normal.

Liu Xiaojian and his colleague had to carry on working at the Wintek factory otherwise their salary would be cut due to absenteeism.

They are only two of a batch of workers who realized that the diseases caused by the toxic chemicals had not been cured.

Although the workers have been to other cities for health checks and diagnosed with diseases, Suzhou hospitals refuted the diagnoses. Taiwanese company Wintek has refused to finance their medical treatments, said another worker, Jia Jingchuan.
