【Abstract】 Objective To study the source of SARS virus by investigating the condition of whether the wild, tamed and domestic anminals carry SARS virus and to compare the SARS virus infection rate in population closedly contacted with animals. Methods From May 2003 on, throat swabs, nasal swabs and fecal swabs were collected from animals in 7 provinces of Guangdong, Guangxi, Fujian and so on for cell culture, IFA and RT-PCR detection. The SARS virus carrying condition of different animals were analyzed. Results 10 animals from 200 animals were detected positive, and among them, 9 were civet cat (the positive rate was 7.96%).Among 1740 people who closedly contacted with animals, the positive rate of SARS IgG was 5.06%;people who sale wild animals had the highest positive rate of 45.45%. Conclusion The results could support the hypothesis that SARS virus were originated from animals(especially civet cat) and could infer that SARS virus might spread from animal to human.更多还原
