TB is the leading cause of death among people who are HIV positive. TB would be serious health problem where there is poor sanitation, poverty and illiteracy. In this paper an attempt is made to know 1.Prevalence of TB in four southern states, 2. Risk factors associated with the infection (TB) and 3.Health seeking behavior among the infected person with TB. Data were collected from NFHS-3 for the four selected states viz: Andhra Pradesh, Karnataka, Kerala and Tamil Nadu analyzes and discussed.

2. Estimated number of new TB cases,2007(WHO)

3. Estimated TB Incidence rate,2007(WHO)

4. Estimated HIV prevalence in New TB cases 2007(WHO)

5. The main Target of global TB control are
• The incidence of TB should be falling by 2015
(MDG Target 6.c)
• TB prevalence and death rates should be
halved by 2015 compared with their level in
1990
• At least 70% of incident smear positive cases
should be detected and treated in DOTS
programs

6. Tuberculosis in India
• Estimated incidence
– 1.8 million new cases annually
– 0.8 million new smear positive cases annually
– 75 new smear positive PTB cases/1lakh population per
year
• Estimated mortality
– 370,000 deaths due to TB each year
– Over 1000 deaths a day
– 2 deaths every 3 minutes

7. Objectives:
• To know Prevalence of TB in four Southern
states
• To assess the Risk factors associated with the
infection (TB) and
• To know the Health seeking behavior among
the infected person with TB in the selected
states in India.

8. Data
• NFHS-3
• “Does any usual resident of your household

member identified as suffering from TB.
• “Has the person suffer from TB received
medical treatment for the TB?.
• For the present study information from the
selected four states viz: Andhra Pradesh
