A middle-aged A/H1N1 patient died in Jerusalem on Thursday night, marking the fifth death case of the global pandemic in Israel, local news service Ynet reported Friday. The victim, in his 50s, who also suffered from other illnesses, died from complications caused by A/H1N1 flu, the report quoted the Health Ministry as saying, adding that he had been hospitalized in Jerusalem for about a week. On Thursday, the Health Ministry changed its policy for counting the victims of the A/H1N1 virus, adding the cases in which the virus cannot be completely ruled out as the cause of death, reported local daily The Jerusalem Post. As a result, the death of a 44-year-old male A/H1N1 flu patient last week in Tel Aviv was added to the list, which already included a 24-year-old woman, a 35 -year-old man and a 12-year-old girl, said the report. Israeli health experts have warned that some one quarter of the Israeli population would contract the virus during a possible outbreak this winter, among whom around 700 would die. The Israeli government pledged to purchase a large amount of vaccines for precaution.
