The World Health Organization has been urging thousands of labs in 18 countries which 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 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.
