Objective To probe the risk factor and routes of transmission of SARS in Guangzhou.
Methods 236 SARS IgG positive cases and 206 negative cases in Guangzhou were selected and the logistic regression was adopted to analyse the related factors.
Results Healthcare workers and multiple persons clustered in the same office or worksplace were apt to infected the SARS virus OR=9.63, 95% CI (3.67-25.26)and OR=4.05, 95% CI (1.34-12.20), respectively; Having not went to hospital during the epidemic period and non-associated with animal were less likely to infect the SARS virus, OR=0.39, 95% CI (0.18-0.83)and OR=0.29, 95% CI (0.14-0.61), respectively; Having not injected the bacterin of measles and flu and the smokers were impressionable to the SARS virsus, though the possibility was not significant, OR=2.03, 95% CI (0.93-4.41) and OR=2.43.95% CI (0.79-7.44), respectively.
Conclusion Persons clustered in the same office or worksplace and badness aeration were the risk factors of infected SARS besides the closely contact with SARS patients. The history of animal contact was significantly correlated to the SARSIgG, which suggested that the SARS virus likely originated from the animals.
