>>Mainland China researcher Zhong Nanshan, who's working with the researcher, said genetic sequencing of the animal SARS viruses appeared more "human-like" - meaning they may be more infectious to humans than the strain involved in the previous outbreak.<< Does this mean animal isolates or the latest human isolate has the 29 nt deletion? Do they have some of the 19 point mutations that last season was only seen in human isolates? Last season SZ3 had 4 additional mutations that were seen in all human isolates, but not other civets or the raccoon dog. Have these mutations begun to appear in more civets and more animals? If so, a new variant not easily verified with existing tests combined with mutations from last season, such as the 29 nt deletion or the 4 dozen point mutations seen in almost all human isolates, could pose problems. Latest China SARS Patient Infected By New Strain Of Virus DOW JONES NEWSWIRES HONG KONG (AP)--A new SARS patient in China was infected by a new strain of the virus that caused last year's worldwide outbreak - and may spread more easily from animals to humans - researchers in Hong Kong said Monday. The 32-year-old man in China's Guangdong province has a strain of the virus that is "different from the animal or human SARS coronaviruses found last year," said researcher Yuen Kwok-yung, head of the microbiology department at Hong Kong University.
