Objective: To understand the epidemiological characteristics of family-clustered SARS cases in Guangdong Province, and to reveal the determinants on the disease transmission.
Methods: The epidemiological characteristics of the family-clustered SARS cases in Guangdong province were investigated by uniform questionnaires.
Results: A total of 191 family-clustered SARS cases with 60 families involved, accounting for 12.6% of all SARS cases, were reported. About 90.6%(173/191) of the cases occurred from January to March 2003. The mortality(9.9%) of them was higher than the general SARS specific mortality (3.7%,P<0.01).About 52.9%(101/191) of the cases aged 30-49 and 13.6%(26/191) of the cases were health care workers, followed by food preparing staffs, accounting for 12.6%(24/191).The first cases from 41.7% of the involved families had apparent or suspect exposure.91 secondary cases from 42 families may be infected during patient accompanying or visiting , accounting for 71.3%.The median of the time interval between the first case and the secondary cases was 7 days.
Conclusion: Family-clustered cases had the comparatively higher fatality, and family-based infection was mainly obtained in hospital.
