Objective:To determine the epidemiological characteristics and incidence trends of sexually transmitted diseases (STD) in Mengla County of Yunnan Province, and provide evidence for future prevention and control of STD. Methods:STD case information from 2005 to 2017 was extracted from the National Notifiable Infectious Disease Report Information System. Data were collected by year and disease type,and the incidence rate, epidemic characteristics and suspicious contact history of STD were statistically analyzed. Results:A total of 1 251 STD cases were reported in Mengla county from 2005 to 2017, including 490 gonorrhea, 483 syphilis, 216 condyloma acuminatum, 16 genital chlamydial infection and 46 genital herpes. The average annual incidence of STD was 35.57/100 000. The majority of STD cases were 20-29 years old (n=541,43.25%), married (n=603,48.20%), Han people (n=638,50.10%), with education of middle school (n=536,42.85%), and occupation of farmers (n=702, 56.12%). The 42.61% of STD cases had non-marital sexual contact history, in which the proportion was significantly higher among male (55.05%) than female (28.98%). In addition, the proportion of non-marital sex among STD cases increased gradually by year and significantly differed. Conclusion:The epidemic status of STD in Mengla county is relatively low. However, STD incidence increased gradually by year, which warrants more and specific measures on the STD control and prevention.

Objective To evaluate the methods in early warning of schistosomiasis and elimination of snails in an ecological public forest in Yexie Town of Songjiang District, and provide the basis for monitoring and controlling snails in forest land in the future. Methods The monitoring data of snails, schistosomiasis and snail elimination in the public forest were collected to evaluate the effect of controlling snails. Results The area with existence of snails was found to be 10.47 hm2, and it was decreased by 98.28% after three times of snail elimination.A total of 1 904 serological tests was performed (test rate of 88.76%) with the positive rate of 0.16%.Pathogenic test result was negative in 3 subjects examined.Serological samples of 11 dogs and 1 sheep were all negative for the test.None of the 1 480 live snails tested was found to be positive in infection.The awareness rate of schistosomiasis control knowledge and behavior formation in 275 students were 98.2% and 95.3%, respectively. Conclusion The snails in the public forest in Yexie Town have been effectively controlled, but there are still scattered living snails.The measures in eliminating and monitoring of snails should be continued and strengthened.
