Health experts have destroyed two-thirds of the specimens of a killer influenza virus sent as part of routine test kits around the world, the U.N. health agency said Friday. It said it still was trying to trace two shipments that were supposed to go to Mexico and Lebanon. The World Health Organization has been urging thousands of labs in 18 countries which had received vials of the nearly 50-year-old H2N2 virus to destroy the samples amid fears of a global pandemic should the virus be released. WHO's influenza chief Klaus Stohr said 10 of the countries which had received samples had confirmed their labs had destroyed the virus. Labs in Lebanon and Mexico, however, "never received the specimen even though they were on the distribution list," Stohr said. He said it was possible the shipments had never been sent out at all, but that he could not be sure. WHO has requested an investigation into the missing kits, he said.
