Airborne: TB is spread
from person to person
through the air. When
people with lung TB
cough, sneeze or spit, they
propel the TB germs into
the air. A person needs to
inhale only a few of these
germs to become infected.

• A total of 1.5 million people died from TB in 2018 (including 251
000 people with HIV). Worldwide.
• TB is one of the top 10 causes of death and the leading cause from a
single infectious agent (above HIV/AIDS).
• In 2018, an estimated 10 million people fell ill with
tuberculosis(TB) worldwide. 5.7 million men, 3.2 million women
and 1.1 million children. There were cases in all countries and age
groups.
• In 2018, 1.1 million children fell ill with TB globally, and there were
205 000 child deaths due to TB.
• In 2018, the 30 high TB burden countries accounted for 87% of new
TB cases. Eight countries account for two thirds of the total, with
India leading the count, followed by, China, Indonesia, the
Philippines, Pakistan, Nigeria, Bangladesh and South Africa.

10. • Globally, TB incidence is falling at about 2%
per year. This needs to accelerate to a 4–5%
annual decline to reach the 2020 milestones of
the End TB Strategy.
• An estimated 58 million lives were saved
through TB diagnosis and treatment between
2000 and 2018.
• Ending the TB epidemic by 2030 is among the
health targets of the Sustainable Development
Goals.

11. Who is most at risk
Tuberculosis mostly affects adults in their most
productive years. However, all age groups are at risk.
Over 95% of cases and death are in developing country .
.
1. People who are infected with HIV
2. Low immune system.
3. People with under nutrition are 3 times more at risk.

12. History of World TB Day
On March 24, 1882, Dr. Robert
Koch announced the discovery
of Mycobacterium tuberculosis, the
bacteria that causes tuberculosis
(TB). During this time, TB killed
one out of every seven people
living in the United States and
Europe.
A century later, March 24 was
designated World TB Day: a day to
educate the public about the impact
of TB around the world.

“tabes” in ancient Rome, and
“schachepheth” in ancient Hebrew.
In the 1700s, TB was called “the
white plague” due to the paleness of
the patients.

14. How is TB diagnosed?
• tuberculin skin test (TST)
• or a blood test called an interferon gamma
release assay (IGRA).
• The TB skin test is also called a Mantoux test
• chest x-ray.
• sputum test

16. In Nepal
• Tuberculosis (TB) is a public health problem in
Nepal that affects thousands of people each year
and is one of the leading cause of death in the
country.
• WHO estimates that around 45,000 people
develop active TB every year in Nepal. Nearly
fifty percentage of them are estimated to have
infectious pulmonary disease and can spread the
disease to others.

17. Vision, goal, objectives of the National
TB Programme
• Vision: TB Free Nepal
• Goal
• To reduce the TB incidence by 20% by the year
2021 compared to 2015 and increase case
notifications by a cumulative total of 20,000
from July 2016 to July 2021, compared to the
year 2015.
17SNC
18. Objective
• 1:Increase case notification through improved
health facility-based diagnosis; increase
diagnosis among children
2: Maintain the treatment success rate at 90% of
patients (all forms of TB) through to 2021.
4: Further expand case finding by engaging
providers.
18SNC
19. 5:Strengthen community systems for
management, advocacy, support and rights.
6: Contribute to health system strengthening
through HR management and capacity.
7: Develop a comprehensive TB Surveillance,
Monitoring, and Evaluation system.
• 8: To develop a plan for continuation of NTP
services in the event of natural disaster or public
health emergency

20. The End TB Strategy
• VISION: A world free of TB
Zero deaths, disease and suffering due to TB
• GOAL: End the Global TB Epidemic
• MILESTONES FOR 2025:

2. 50% reduction in TB incidence rate (less than 55 TB
cases per 100,000 population)
3. No affected families facing catastrophic costs due to TB
• TARGETS FOR 2035:
1. 95% reduction in TB deaths (compared with 2015)
2. 90% reduction in TB incidence rate (less than 10 TB
cases per 100,000 population)
