The Ministry of Health announced Wednesday that it had detected the Kingdom's first case of swine flu, found in a Filipina nurse working at King Faisal Specialist Hospital and Research Center in Riyadh. The nurse had been on vacation in the Philippines and returned to the Kingdom on Friday on board a Gulf Air flight, the Saudi Press Agency (SPA) quoted Minister of Health Dr. Abdullah Bin Abdul Aziz Al-Rabeah as saying. Al-Rabeah added that the woman showed no sings of symptoms of the virus upon her arrival. “She started showing symptoms on Monday and was admitted to King Faisal Specialist Hospital where preliminary tests showed that she was swine flu positive.” According to World Health Organization protocol the test was repeated at the Ministry's Central Laboratory and results on Monday confirmed that the nurse was suffering from H1N1/A. Al-Rabeah said the ministry's Preventive Medical Agency and King Faisal Specialist Hospital had put into effect procedures defined in the Anti-SF National Plan which include the quarantining of the nurse and provision of treatment as well as the scanning of all persons with whom she has come into contact. The Ministry of Health has appealed to all passengers who flew from Bahrain to Riyadh last Friday on board Gulf Air flight 163 to contact the Preventive Medicine Agency at the Ministry of Health in Riyadh for tests to ensure they are not carrying the swine flu virus.
