The feasibility of carrying out tuberculin testing of children in the community and reliability of data collected, by general health workers are essential pre -requisites for the development of a surveillance methodology based on the study of infection rates. These aspects were investigated in two districts of South India, following their acceptance of the responsibility to carry out the field work. Around 97% of the eligible children in 0-9 years age group could he tuberculin tested. Thus, the community response to the activity was good. There was a high level of agreement between the standard tuberculin reader of the NTI and the trainee readers belonging to the general health services, in measuring tuberculin induration sizes of over 10 mm, especially over 14 mm (99%). Also, in estimating the prevalence rates of infection on the basis of the two kinds of readings. It could be concluded that there are no technical or operational obstacles in implementing tuberculin testing through general health services for starting surveillance activity.
