The World Organisation for Animal Health (OIE) received this information
from the veterinary bureau of the Chinese ministry of agriculture.
Since the end of June, pigs have died of a disease characterised by rising body temperature, redness of the skin and rapid breathing in some parts of six provinces of China, namely Hunan, Jiangxi, Anhui, Jiangsu, Zhejiang and Hubei.
A similar swine disease was also found in some southern provinces of China in hot summers during the last few years.
Chinese authorities said they are arranging for a microbiologist to conduct further research.
