Three people are infected with a pig-borne disease in the southern region of China and one has died, a day after an epidemic in another part of the country was declared under control.

The Xinhua News Agency reports that those infected reside in four different areas in Guangdong province.

No pigs were reported sickened by Streptococcus suis, the bacteria blamed for the human cases and how the people were infected is unclear. The disease is usually passed on through contact with raw pork or sick swine.

On Sunday, China's ministries of health and agriculture said that an outbreak of the disease in Sichuan province was under control.

More than 200 people became sick, at least 38 died in the epidemic, first detected in June.

Symptoms include high fever, nausea and vomiting, followed by meningitis, hemorrhaging under the skin, toxic shock and sometimes coma. Some have also suffered organ failure.

Medical teams have been sent to investigate and help locals take protective measures.

The Guangdong departments of health and agriculture have also been mobilized "to take emergency measures and work strenuously to prevent the disease from spreading," says Xinhua.
