Objective: To reduce mortality and to control the epidemic of severe acute respiratory syndrome ( SARS ) through analyzing the epidemiological characteristics of the dead cases of SARS.
Methods: The epidemiological distribution, the conditions of primary diseases and the causes of deaths of all dead cases with SARS reported between Jan 2 and August 30 2003 in Guangdong province were investigated by uniform questionnaire.
Result: As of August 30 , accumulative total of 1512 SARS cases were reported in Guangdong province with the mortality of 3.83% (58/1512). Most of the death occurred in GuangZhou, where reported the most cases. The peak of mortality 11.1%(4/16) occurred in the first ten days of January, and no deaths occurred after May 20.The mortality increased with the aging of the patients (X2=184.2, p<0.001). The mortality was 13.5%(12/84) among the cases aged 70 years old or above, followed by the cases aged 60-69(9.91%). The mortality was the highest (15.63%, 5/32) among farmers.17 of the dead cases had severe basic diseases (29.8%). No significant difference of the mortality was observed between clustered cases (4.64%, 24/523) and the sporadic cases (3.34%,33/989)( X2=1.47,p>0.05). But the difference between community-based clustered cases (10.11%,19/188) and the hospitals-based (1.49%,5/335)( X2=20.407, p<0.001) was statistically significant. In terms of the determinants of the deaths, both the community-based clustered infection(OR=4.73,95%CI:2.50,8.95) and aging (OR=1.05,95%CI:1.03,1.06) were selected (p<0.01)
Conclusion: SARS could be cured and the mortality can be reduced after information available. In order to reduce the mortality of SARS, we should pay more attention to the community-based clustered cases, senior cases those with basic diseases.
