3. Introduction
ďą Tuberculosis is a chronic infectious disease
caused by Mycobacterium tuberculosis
which was discovered by Robert Koch
ďą Also known as âKochâs Bacillusâ
ďąThe most common organ involved is
lung(>80%) but it can involve any organ of
the human body (except hair and nails)
ďąIt usually affects human in the age group of
15 to 59 yrs

4. Classification of TB
TB
Pulmonary (85-90%) Extra-pulmonary (10-15%)
Sputum
Positive TB
(Those who
have
bacteria in
sputum)
Sputum
Negative TB
(Those who
do not have
bacteria in
sputum)
ďźLymph Nodes
ďźJoints
ďźGenitourinary
tract
ďźSpinal tract
ďźIntestines
5. Symptoms of TB
Most common symptom of TB
⢠Cough for 2 weeks or more
Other symptoms of TB are:
⢠Fever, especially evening rise
⢠Pain in the chest
⢠Loss of weight
⢠Loss of appetite
⢠Coughing up blood-stained sputum
⢠Shortness of breath,
⢠Tiredness
6. How TB Spreads ?
⢠Those who have Tuberculosis of the lungs are the ones
who can spread the disease to others
⢠When these infectious people cough, sneeze, talk or
spit, they can spread TB bacteria into the air in the form
of tiny droplets
⢠When these droplets are inhaled by a healthy person
he/she can get infected with tuberculosis
A sputum positive TB patient can infect 10-15 persons in a
year
7. When to Suspect TB
TB should be suspected in anyone with cough for 2
weeks or more
These persons should have sputum examination in the
nearest Microscopy Centre at the earliest
8. TB-HIV co-infection
ďąTB is the most common opportunistic infection
amongst HIV infected individuals
ďąAn HIV infected person newly infected with TB has
10-30 times higher chances of developing TB than
those without HIV
ďąIn India, 55-60% of AIDS cases reported had TB and
TB is one of the leading causes of death in âPeople
Living with HIV AIDSâ (PLHA)
Every TB patient should be referred to ICTC for HIV
status and vice versa
9. Risk of infection
ďą About two persons infected in every 3 seconds
ďą About 50% are sputum smear positive and are infectious
ďą TB infected person will have a 10% lifetime risk of
developing tuberculosis
ďą Infection of TB is 60 times more common in HIV +ve
people than Non-HIV +ve
ďą Diabetes, malignancy, smoking tobacco, malnutrition and
alcohol abuse also increase the risk of progression from
infection to disease
ďą 2 out of every 5 Indians are infected with TB bacillus
10. BURDEN OF DISEASE
WORLD:
ďąTB continues to be one of the most important public
health problems worldwide
ďą In 2014, an estimated 9.6 million people developed TB
and 1.5 million died from the disease, 400,000 of whom
were HIV positive
ďą Worldwide the proportion of new cases with MDR-TB
was 3.3% in 2014, whereas those for previously treated
cases was 20.0%
11. ďąOf the estimated 9.6 million people who developed
TB in 2014, more than half (58%) were in South-East
Asia and Western Pacific regions and a further one
quarter (28%) were in African region
ďąIndia, China and Indonesia alone accounted for 23%,
10% and 10% of total cases respectively
ďąIn 2014, an estimated 3.2 million cases were women
12. ďąAn estimated 510,000 women died as a result of TB,
more than 1/3rd of whom were HIV positive
ďąGlobally, about 1.1 million new cases and 130,000
deaths occur annually due to TB among children
(Global TB report 2015)
13. INDIA
ď§ Accounts for nearly 1/4th of the global burden of TB
ď§ Around 2.2 million develop TB in 2013-14. During the
same period, 0.27 million people died due to TB
ď§ Everyday about 20,000 people become infected, 5000
develop TB and more than 1000 die due to the disease
ď§ In simple terms, 2 persons become sputum +ve for TB and
almost 1 person is killed every minute due to the disease (
WHO 2007)
ď§ The proportion of new cases with MDR-TB was 2.2% in
2014, whereas those for previously treated cases was 15.0%
14. Brief History of Tuberculosis (TB)

confirmed that TB is contagious
- Robert Koch:
- 1882: Isolated and cultured M.
Tuberculosis(24th March)
- 1890: Announced the discovery of
tuberculin
- Developed staining methods used to
identify the bacteria
- 1905: Received Nobel Prize
Visualization of M. tuberculosis
using the Ziehl-Neelsen stain
15. ⢠Bacteriologist Paul Ehrlich developed Ziehl-Neelsen
staining
⢠Before 1940
â Sanatorium approach, good food, rest & fresh air
⢠1948
â Introduction of BCG vaccination
⢠1950s-60s:
â Antibiotics available
16. Background History of RNTCP
â 1906- First open air TB sanatorium founded in
India
â 1939- TB association of India
- expert advice on the development of
standard methods to deal with the disease;
- setting up model institutions for training TB
workers;
- education of the public regarding preventive
measures;
- conceived the idea of domiciliary Rx of TB
in 1940
17. ⢠1946- Bhore Committee recommended to the GOI, setting
up TB clinics in the districts and mobile TB clinics in rural
areas.
⢠1947- GOI established a TB division under DGHS in the
MoH, Planning and execution of anti-TB activities were
greatly facilitated by this Division.
⢠1951- Mass BCG vaccination campaign covering 65 million
children in collaboration with IUAT
⢠165 million tuberculin tests were administered to find the
prevalence of TB in India
18. ⢠1955-58 - National Sample Survey conducted under
ICMR to find the magnitude of TB problem in India
⢠1956- TRC established in Chennai
- Proved the efficacy of domiciliary Rx for
TB with chemotherapy
⢠1959- National TB Institute (NTI) established in
Bangalore by GoI, with the active cooperation of the
WHO, to develop a TB control programme
19. ⢠1962- National TB Control Program(NTCP) started
ď˛Managerial weakness, lack of supervision
ď˛Poor quality of sputum microscopy
ď˛Multiplicity of treatment regimens
ď˛Poor organizational set-up
ď˛Inadequate funding

23. Revised National Tuberculosis Control
Programme
o The National TB Programme (NTP) was started in 1962
for TB control in India. This programme was not able to
give expected results in India
o The NTP was reviewed in 1992
o As a result of the review and pilot studies in 1993, the
DOTS strategy was adopted in India under the Revised
National TB control Programme - RNTCP
o The programme was implemented in a phase manner
and by 24th March 2006, the entire country was covered
under the programme
24. Goal
The goal of RNTCP is to decrease the mortality and
morbidity due to tuberculosis and cut down the chain of
transmission of infection until TB ceases to be a public health
problem
Objectives
To achieve and maintain:
o Cure rate of at least 90% among newly detected smear
positive (infectious) pulmonary TB cases and
o Case detection of at least 85% of the expected new smear
positive PTB cases in the community

Assessment
ďąOperational research to inform TB Control policy and
practice
30. Strategies
1. Case finding and Diagnostics:
ďą Early identification of all infectious TB cases
ďą Improved integration with the general health system and
leverage field staff for home-based case finding
ďą Improve communication and outreach
ďą Screening clinically & socially vulnerable risk groups for
TB
ďą Develop improved sputum collection and transportation
systems

decentralized DST services
ďą Catch patients already diagnosed through notification
from all sources
ďąImproved referral for treatment mechanisms, and
deployment of Laboratory & Private Provider
notification
32. Strategies
2. Patient friendly treatment services: DOTS strategy
ďą Promptly and appropriately treating TB, increasingly
guided by DST
ďąMaking DOTS more patient friendly through â
communitization of DOT
ďąpilot incentives/offsets for patient costs to help patients
complete treatment and better monitoring through IT
ďą Improving partnerships between public and private
sector
33. Strategies
3. Scale-up of Programmatic Management of Drug
Resistance âTB (PMDT):
ďąDeveloping network of C&DST Laboratories &
Strengthening of Reference Laboratories
ďąDecentralized DST at district level for early MDR
detection
ďą Improved information system for PMDT
34. Implementation
⢠Case finding- by passive surveillance on patient with
symptoms of
i) Persistent cough for 2weeks or more.
ii) Haemoptysis
iii) Night sweats
iv) Evening rise of temperature
v) Chest pain
In lab.-
i) Sputum collection for diagnosis
ii) Radiography
iii) Tuberculin test
35. ⢠Diagnosis of TB
Sputum examination is the best method to diagnose TB
⢠Pulmonary TB diagnosis can be confirmed by sputum
examination. Two sputum samples are collected over
one/two consecutive days
⢠If the health facility is a DMC, spot sample is collected
immediately and the patient is given a sputum container
to collect early morning sample & brought to the lab
36. ⢠Alternatively the patient can be asked to collect a
morning sample and go to a DMC where a spot sample
can be taken
⢠In case the patient is not able to reach a DMC, both
samples - morning and spot, can be collected and
transported
37. ⢠The sputum samples are subjected to microscopy
examination as early as possible
⢠A patient is diagnosed positive if one or both the
samples is positive for bacteria
⢠If the bacteria are not visible in any sputum
sample, the patient is negative and should be
referred to a medical officer for further evaluation
⢠TB of other organs is diagnosed by a medical
officer
38. RNTCP revised diagnostic algorithm (2009)
Note: RNTCP has
separate diagnostic
algorithm for
pediatric pulmonary
TB and common
forms of extra-
pulmonary TB
40. Directly
observed
treatment
(DOT) is one
element of
the DOTS
strategy
An observer
watches and
helps the
patient
swallow the
tablets
Direct observation
ensures treatment
for the entire
course
⢠with the right
drugs
⢠in the right doses
⢠at the right
Directly Observed Treatment
41. Components of DOTS
DOTS is a systemic strategy to control TB diseases. It has
the following 5 components -
1. Political and administrative commitment
2. Good quality diagnosis, primarily by sputum smear
microscopy
3. Uninterrupted supply of quality drugs
4. Directly observed treatment (DOT)
5. Systemic monitoring and accountability
42. DOTS
1- Intensive Phase(IP):-
ď§ Intensive phase is of 2 to 3 months duration
ď§ Patient swallow medicine under the observation of
a health worker during IP
ď§ Medicines are taken 3 times a week on alternate
days
ď§ If the sputum is negative for bacteria after IP,
continuation phase is started
Directly Observed Treatment Short Course
There are two phases in DOTS treatment
43. DOTS
2. Continuation Phase
⢠This phase is of 4 or 5 months duration
⢠The patient is provided with a weekly blister pack to take
home
⢠The medicines from the blister pack are taken on
alternate days, three times a week and in the remaining
days, Vitamin tablets are taken

54. WHO definitions of TB cases recommended
for use since March 2013
⢠Bacteriologically confirmed case of TB: A patient from
whom a biological specimen is positive by smear
microscopy, culture or WHO-approved rapid diagnostic test
(such as Xpert MTB/RIF)
⢠Clinically diagnosed case of TB: A patient who does not
fulfil the criteria for bacteriologically confirmed TB but has
been diagnosed with active TB by a clinician or other
medical practitioner who has decided to give the patient a
full course of TB treatment
55. ⢠Case of pulmonary TB: Any bacteriologically confirmed
or clinically diagnosed case of TB involving the lung
parenchyma or the tracheobronchial tree. Miliary TB is
classified as pulmonary TB because there are lesions in the
lungs. Tuberculous intra-thoracic lymphadenopathy
(mediastinal and/or hilar) or tuberculous pleural effusion,
without radiographic abnormalities in the lungs, constitute a
case of extrapulmonary TB. A patient with both pulmonary
and extrapulmonary TB should be classified as a case of
pulmonary TB.
56. ⢠Case of extrapulmonary TB: Any bacteriologically
confirmed or clinically diagnosed case of TB involving
organs other than the lungs, e.g. abdomen, genitourinary
tract, joints and bones, lymph nodes, meninges, pleura,
skin
⢠New case of TB: A patient who has never been treated for
TB or has taken anti-TB drugs for less than one month
⢠Retreatment case of TB: A patient who has been treated
for one month or more with anti-TB drugs in the past.
Retreatment cases are further classified by the outcome of
their most recent course of treatment into four categories.
57. 1. Relapse patients have previously been treated for
TB, were declared cured or treatment completed at
the end of their most recent course of treatment, and
are now diagnosed with a recurrent episode of TB
(either a true relapse or a new episode of TB caused
by reinfection)
2. Treatment after failure patients have previously
been treated for TB and their most recent course of
treatment failed i.e. they had a positive sputum smear
or culture result at month 5 or later during treatment
58. 3. Treatment after loss to follow-up patients have
previously been treated for TB and were declared
âlost to follow-upâ at the end of their most recent
course of treatment
4. Other previously treated patients are those who
have previously been treated for TB but whose
outcome after their most recent course of treatment is
unknown or undocumented
