The Computerized Management Information System (CMIS), National AIDS Control Organization’s (NACO) online data capturing system, systematically collects information on TTIs in a monthly aggregated format from blood banks across the country. This information is being captured in NACO’s annual reports, but a systematic scientific analysis and publication of the same have not been attempted so far. Hence, the objective of this study is to analyze and report TTIs among blood donors in India at three different levels—national, regional and state—from 497 consistent blood banks reporting through CMIS during 2008-2012. National level analysis shows an increasing trend in voluntary blood donation from 9.28 lakh to 19.02 lakh, and a decreasing trend in TTIs, with female donors constituting only 6% of the entire pool of donors. Of the five TTIs studied, in 2012 Hepatitis-B-surface Antigen (HBsAg) positivity was highest (0.9%), followed by Hepatitis C Virus (HCV) (0.45%), syphilis (0.23%), HIV (0.17%) and malaria (0.03%). Regional analysis indicated that voluntary donation was high in the Eastern and Western regions, with 11% of female donors in Eastern India in 2012. All the TTIs showed a declining trend, except HCV, which showed a rising trend in the Eastern and Southern regions. The level of positivity for all the five TTIs was higher than the national average in the Eastern region. Among the TTIs, HIV positivity among voluntary donors was below the national average, while in Mizoram both HBsAg and HCV of more than 1% seropositivity and VDRL of 1.7% in Arunachal Pradesh had been reported. Malaria has the lowest national positivity, with Nagaland reporting a high positivity of 0.4%. Although the national and regional trends in TTI positivity are declining, regional level variations in TTIs, especially in hepatitis, suggest the importance of advocating for pre-donation counseling and educating donors on self-exclusion.展开更多
