ABSTRACT
Objective To analyze the epidemic characterization of syphilis infection among non-remunerated blood donors based on data of Huainan area from 2011 to 2016,and thus to provide scientific evidence for recruitment and reserve of blood donors in the future.Methods All serum samples were tested for syphilis by screening with ELISA to make definite diagnosis for the samples with positive results.Data of syphilis infection were collected and analyzed for epidemic characterization and trend.Results There were 139 078 serum samples of blood donors,the samples were tested for syphilis and confirmed 847 samples with positive result,the positive rate of syphilis infection was 0.61%.The positive rate of syphilis infection showed a downward trend from 2011 to 2016.Females were more than males and the sex ratio was 1:1.2 among all positive samples.The positive rate of people with 45-55 years old was the highest,and the lowest positive rate came from people with 18-24 years old.The positive rate of syphilis infection increased with the decrease of levels of education,among them,the primary school and below was the highest 1.36%,bachelor degree or above was the minimum 0.29%.Repeated and units-organized blood donors were the most ideal blood donors,and the infection rate of syphilis was much lower than the other donors.Conclusion The positive rate of syphilis infection among non-remunerated blood donors in Huainan area showed a downward trend.Syphilis still remains high threat to the safety of blood.We should strengthen the work of recruitment for the low-risk blood donors,and provide targeted health education propaganda for different blood donors.
ABSTRACT
Objective To control IDS virus (HIV)transmission through blood, provide low -risk blood donors to donate regularly, and ensure blood safety and reduce the risk of blood transfusion. Methods By analyzing HIV antibody(anti-HIV) test results, HIV infection and prevalence of blood donors from 2000 to 2009, susceptible people were identified,prevented,educated,in order to prevent the spread of HIV. Results A total of 10 years in Huainan region 361 cases of anti-HIV positive were screened out. Anti-HIV-positive of voltmtary blood donors were recognized anti-HIV positive in 4 cases ,accounting for 0.209/10 000 of the total voluntary blood donation. Epidemiological analysis in 4 cases of anti-HIV confirmed positive results: the education level of all was less than high school,75% were the local household registration ;25% were mobile population, and all were young adults, aged from 23 to 38 years;75% were workers,and 25% were temporary workers and the service sector. Conclusion By strictly blood screening to blood donation, strengthening the management, intensify propaganda against AIDS in efforts, raising people 's awareness of prevention,the spread of AIDS could be prevented and controlled.
