A cross-sectional study was conducted in 7 selected holy water sites found in North Gondar zone: two holy water sites in Gondar town, two in Chilga district, two in Dembia woreda and one in Tikele Dingay. North Gondar zone is located 739 km away from the capital city, Addis Ababa towards the Northwest part of Ethiopia. Selected holy water sites are among popularly believed sites for holy water treatment which can accommodate large numbers of people and the high number of holy water users that travel to these sites every year. Northwest part of the country contains many holy water sites and high proportion of holy water users. In North Gondar zone, northwest part of Ethiopia, 95% of the population practice Ethiopian Orthodox Christianity which widely practice a faith based therapy with holy water [19 ].
The study was conducted from February 01, 2015 to March 30, 2015. The minimum sample size (n) was determined by using single population proportion formula [n = (Z α/2) 2 P (1-P) /d2], where Zα/2 = the value under standard normal table at 95% level of confidence which is 1.96, expected prevalence P, set at 50% to yield maximum sample size, d = precision which was set at 5%. Including 10% non response rate, the final sample size was 422 PTB suspects. However, a total of 382 PTB suspects participated in the study.
