"Its unique sequence suggests that it has evolved independently from the other members of the family, in some animal host, for a long time," says Malik Peiris, a virologist at the University of Hong Kong. Recent investigations by researchers at the China Agricultural University in Beijing, for instance, have failed to find SARS-like coronaviruses in 732 animals from 54 wild and 11 domestic species in southern China, including palm civets. "The animals walk in and out of their houses," says Kenneth Shortridge, who led the University of Hong Kong's efforts to monitor avian viruses in southern China until his retirement last year.	./cache/cord-015009-3o90pzw7.txt	./txt/cord-015009-3o90pzw7.txt
