“As regards seasonal influenza, Dr Tsang remarked that
the peak season is about to arrive in Hong Kong. “According to historical trend, the peak season for influenza is expected to come in February or March. People at high risk and have not received influenza vaccination should get vaccinated as soon as possible.” He said that more than 240 000 people have already been covered by the government’s influenza vaccination programme, compared with 200 000 people in 2004. This represents an increase of about 20% over 2004. http://www.info.gov.hk/dh/new/2006/Jan/060124e.htm -------- 01/27/2006 The Asahi Shimbun The flu bug that is causing misery this winter increasingly seems to be resistant to standard treatment authorized by doctors, researchers say. Three drugs are normally used to treat flu, but one, Amantadine, which is prescribed as Symmetrel, has had little or no effect, they said.

A team of researchers led by Norio Sugaya, director of tche pediatrics department of Keiyu Hospital in Yokohama, found 21 cases in which virus samples were resistant to Amantadine. In total, the team examined 24 people who displayed type A influenza and sought treatment at medical institutions in Yokohama from December to January. Of the 24, 18 were infected with type A Hong Kong flu and six with type A Soviet flu. Virus samples from 16 of the Hong Kong flu patients were found to be resistant to Amantadine. Those taken from five Soviet flu patients had the same result. Researchers said, however, that none of the total of 21 patients had been prescribed Amantadine by doctors. On Jan. 14, the U.S. Centers for Disease Control and Prevention warned that Amantadine and the drug Rimantadine should not be used for flu treatment this winter season.(IHT/Asahi: January 27,2006) http://www.asahi.com/english/Herald-asahi/TKY200601270162.ht ml Delete.
