Twelve Zamalek swimmers have been diagnosed with Swine flu along with their coach, club's spokesman Sabri Serag said. The swimmers were infected right after their participation in the Cairo Championship, which took place at Ahli. "There were more than one thousand swimmers at same area, and that's why some people went down with swine flu," Serag told Ahli's space channel. Swine flu, an airborne virus that could be lethal in rare cases, has been spreading around the globe over the past few months.
