Syphilis is a sexually transmitted disease and its actual prevalence among Pakistani blood
donors is currently unknown. A cross sectional study was conducted at different district
healthcare hospitals of Punjab, Pakistan with an aim to evaluate the prevalence and risk
factors associated with syphilis in blood donors using immunochromatographic test (ICT)
and enzyme linked immunosorbent assay (ELISA). A total (n=1200) blood samples were
collected from donors aged 18–65 years. All the information regarding personal data,
demographic data and risk factors was collected via structured questionnaire. On the basis
of ICT and ELISA, the overall prevalence of syphilis was 3.91% among blood donors. The
demographic factors positively linked with syphilis were age (P= 0.000; Odds ratio, OR= 7.18;
95% confidence interval CI= 2.816–18.295) and education status (P= 0.000; Odds ratio, OR=
12.33; 95% confidence interval CI= 3.469–43.849) of donors. Similarly among the risk factors
analyzed, marital status (P= 0.012; Odds ratio OR= 2.251; 95% confidence interval CI= 1.206-
4.202) and blood transfusion history (P= 0.030; Odds ratio OR= 1.981; 95% confidence interval
CI= 1.083-3.623) were also strongly associated with syphilis. We emphasized the importance
of promoting preventive measures for syphilis. The syphilis diagnosis should not be based
on a single test. The present study indicates that higher prevalence is alarming for blood
donors in Pakistan. Stringent donor screening is highly recommended to ensure maximum
safe blood transfusion.

Human brucellosis is a neglected zoonotic problem worldwide with a high degree of morbidity in humans and is mostly overlooked due to other febrile conditions. The aim of this study was to evaluate the sero-prevalence and risk factors of human brucellosis among subjects living in Punjab, Pakistan. In this cross-sectional study, human blood samples were collected from seven districts of Punjab, Pakistan. Information regarding personal data, demographic data and potential risk factors was collected through a structured questionnaire. Detection of anti-Brucella antibodies was done through Rose Bengal Plate Test (RBPT) and Enzyme Linked Immunosorbent Assay (ELISA). Descriptive analysis, Chi square test and Odds ratio was applied using STATA software version 12. The sero-prevalence of human brucellosis was 13.13% with significantly higher percentage in males 17.23% and age group 25-40 years 16.50% (P=< 0.001). The demographic factors positively associated with human brucellosis were lack of education (P = 0.003; OR = 1.85) and farming as an occupation (P =<0.001; OR = 2.50) Similarly, among the risk factors studied, keeping animals at home (P =<0.001; OR = 2.03), slaughtering of animals (P =<0.001; OR = 15.87) and consuming raw milk (P =<0.001; OR = 5.42) were the factors strongly connected with human brucellosis. A massive awareness should be given to livestock farmers and individuals directly linked to animals regarding risk factors and transmission of brucellosis. Consumption of unpasteurized milk and its products should be condemned to curtail this neglected disease.
