BEIJING - The World Health Organization urged China on Friday to conduct more tests on a pig-borne disease that has killed 38 people in the country’s southwest, the worst outbreak in the region in recent years. Roy Wadia, a WHO spokesman in Beijing, said China had been giving the organization updates from Sichuan province on the disease blamed on the Streptococcus suis bacteria. But more tests were needed to “eliminate other possible scenarios,” he said."Doing tests of different sorts is something we would recommend ... in any outbreak situation, especially in one of this scale,” Wadia said.
