Managers of the selected projects were contacted and screening
camps were conducted on fi xed days from 9 am to 2 pm at the
project sites without affecting the work. In case there is more than
one work site under one project the workers were transported to the
main camp sites. Since the workers camp sites were near the project
sites and free medicines were distributed, maximum participation
was ensured and those with sickness absenteeism also attended the
screening thus enabling us to elicit maximum morbidity.
