The purpose of this study was to find out whether
the prevalence of infection in young children might be used as an
index of the tuberculosis problem in a population. Tuberculin testing
was done in a random sample of 2,883 children (0-4 years) in Bangalore
city, of those 2,589 (89.8%) actually completed testing. A total
of 4340 children were registered in 59 villages and of these 4090
(94.2%) were tuberculin tested. The villages were from Bangalore,
Kolar and Mandya as these districts were within 100 miles from Bangalore
city. The team went from house to house and made a complete registration
of the children 0-4 years in the selected houses. Information on
socio-economic status, density of population etc., was also collected
before giving tuberculin 1 TU RT 23 with Tween 80.
The results of the study showed that prevalence
of infection in 0-4 years age group of cantonment area was 1.6%
and in the crowded city area 4.1% at 14mm induration level. In the
rural population, the prevalence of tuberculosis infection was 2%.
In the city, a positive correlation between tuberculosis infection
and socio-economic condition was obtained while it was not seen
in rural areas. It was not possible to establish any correlation
between tuberculosis disease and infection either in rural or urban
areas, as the population was not examined for the prevalence of

The objective was to establish the prevalence rates
for tuberculosis infection, radiologically active pulmonary tuberculosis
and bacteriologically confirmed diseases for different age and sex
groups. Tumkur District in Mysore State consisting of 2,392 villages,
10 towns of was selected for the study. The district headquarter
town Tumkur was excluded from the survey. Random sample of 62 villages
and 4 town blocks having a population of 34,746 persons constituted
the study population. All the individuals available in the registered
population were given a Mantoux test with 1 TU RT 23 with Tween
80. Longitudinal diameter of induration was read 3-4 days after
the test. At the time of tuberculin test, all persons aged 10 years
and above were offered a single 70mm photofluorogram. For each picture
read as abnormal, a spot specimen of sputum of the individual concerned
was collected at the time of reading the tuberculin test. Age and
sex distribution of infection and disease were studied.
Various parameters concerning the prevalence of
infection and disease in the community were reported. Prevalence
rate of infection in all ages and both sexes of the population was
found to be 38.3%, radiologically active tuberculosis 1.86% and
0.41% sputum positive disease. The infection and disease increased
with age; of the total diseased, half were in age group 40 years
and more and about 2/3 among males.

|REPORT ON THE FIRST AND SECOND PASSIVE FOLLOW-UPS
OF CHILD POPULATION IN 0-14 YEARS AGE GROUP IN A SLUM AREA OF BANGALORE

Newsletter 1977, 14, 97-104.
The findings of the two follow-ups conducted passively,
in a slum area of Bangalore city, each at an interval of one year,
are presented here. The objectives of the follow-ups were to study
the migration, episodes of sickness and health status of sick people
of initial survey over a period of time in the pediatric age group.
The information was collected by two ways: (1) by visiting each
house to collect information on sickness among them during the preceding
year as per the questionnaire. (2) Going through the records of
the Area Health Centre about various morbidities among the residents
of the area pertaining to symptoms, diagnosis and treatment during
any year noted.
Migration had occurred upto 7% in 0-9 year age
group within first year and no migration during second year in 0-4
year age group. Out of 400 children belonging to 0-14 years, had
symptoms related to respiratory system. In all, 5 children were
diagnosed as case of active primary tuberculosis, non-e died in
two years and one had persistent respiratory symptoms. Hospital
records showed that only 1 out of 5 had attended any health facility
with respiratory symptoms. The usefulness of passive follow-up without
clinical investigations as a tool, needs to be reviewed. Most of
the symptomatics do not go to hospital. Diagnosis cannot be arrived
at by passive follow-up. It may be necessary to decrease the interval
of follow-ups if it is desired to get precise idea on frequency
of episodes of sickness, as most of the sicknesses are forgotten
by the population with passage of time.
