China's ministry of health says 34 people have died from a disease, caused by streptococcus suis bacteria, carried by pigs.

On Saturday, the ministry released new figures saying 174 cases of the illness, commonly called swine flu, have been identified. That is an increase of 22 over Friday's figure. There were three additional deaths in the same period.

China's official news agency Xinhua reports that one of the new cases came from Guangdong province near Hong Kong. That would be the first case outside Sichuan province, where the outbreak began. Xinhua says a slaughterhouse worker in Guangdong was treated and released from the hospital.

Those infected have handled infected pigs or infected pork. China says there has been no human-to-human transmission of the disease.
