RESEARCH significance was obtained (p 0.199 to 0.854) to all vari- ables, except for the variable about visiting the Amoy Gardens (p < 0.05). One particular strength of the study in its evaluation of the three public health measures is that transmissions due to various known sources of infection had been removed as much as possible. In conclusion, the study shows that pub- lic health measures may have contributed substantially to the control of SARS epidemic in Hong Kong. This study was solely funded by the Chinese University of Hong Kong. Dr. Lau is the director of the Center for Epidemiology and Biostatistics of the School of Public Health of the Chinese University of Hong Kong. His research interests include commu- nity research on behavioral aspects of infectious disease, such as HIV prevention studies. References 1. World Health Organization.
