SARS virus is mutating, fear doctors 15:55 16 April 03 NewScientist.com news service A cluster of SARS patients in Hong Kong with unusual symptoms has prompted concern that the virus causing the disease is mutating. Doctors fear the changes are making the disease more severe. Scientists in Hong Kong are now urgently sequencing key genes from recently isolated coronaviruses to reveal any changes. New Scientist has learned that the changes in symptoms mirror those already seen when animal coronaviruses have mutated. Microbiologist Yuen Kwok-yung, at the University of Hong Kong, said on Wednesday that the 300 patients from a SARS hot spot, the Amoy Gardens apartment complex, were more seriously ill than patients who acquired the infection elsewhere. The Amoy Gardens patients are three times as likely to suffer early diarrhoea, twice as likely to need intensive care and less likely to respond to a cocktail of anti-viral drugs and steroids. Even medical staff who caught the infection from Amoy Gardens patients are more seriously ill, Yuen said. newscientist.com
