Health is a state of complete wellbeing free from any discomfort and pain. Despite remarkable world-wide progress in the field of diagnostic, curative and preventive medicine, still there are large populations of people living in isolation in natural and unpolluted surroundings far away from civilisation, maintaining their traditional values, customs, beliefs and myths. India has the second largest tribal population of the world next to the African countries. About half of the world’s autochthonous people live in India, thus making India home to many tribes which have an interesting and varied history of origins, customs and social practices. Indian Tribal communities are experiencing latent phase that is potentially a precursor for infectious diseases like Hepatitis. This study was contemplated to analyse the prevalence of infections caused by Hepatitis B, and to analyse the risk factors for HBsAg transmission among the Malayali tribes India.
Materials and Methods
Serum samples were collected from 150 participants of Malayali tribes and were tested for serological markers of HBV (HBsAg). The data was analyzed using SPSS 21 and Chi square test to determine the risk factors of Hepatitis B virus among Malayali tribes.
In the study, HBsAg positivity was observed in higher percentage in males 13 (8.6 %) than females 12 (8 %) and their all age groups indicate the high prevalence of HBV infection. Analysis of risk factors showed that jaundice in family, tattooing, series of injection, sexual promiscuity and surgery with blood transfusion plays a major role in transmission in spread of Hepatitis B virus.
Hepatitis B is a major health problem in Malayali tribes and need to design intervention strategies among this tribal population.
