This document summarizes the global burden of tuberculosis (TB) in 2011. Some key points: - There were an estimated 8.7 million new TB cases and 1.4 million TB deaths in 2011. The majority of cases and deaths occurred in Asia and Africa. - TB is a leading cause of death among people living with HIV, with 1.1 million new HIV-associated TB cases in 2011. 80% of the global TB/HIV burden is in Africa. - There were an estimated 630,000 multi-drug resistant TB cases in 2011, with over 60% occurring in China, India, Russia and other countries. - Women and children also face a large burden,

…El Cardenal tiene una salud frágil, consecuencia de una tuberculosis
que lo atacó cuando era un niño y le dejó secuelas: le falta la parte
superior alveolar del pulmón derecho… Sin embargo, físicamente es
fuerte. El mismo se esfuerza para no ser menos que los demás y practica
natación…

13. What
are
the
challenges
in
2013
if
we
target
beher
care,
control
and
ulEmately
“eliminaEon"?
1. Funding
not
secure
at
system
and
individual
level:
TB
is
a
catastrophic
expenditure
for
the
poor
2. TB/HIV
major
impact
in
Africa,
especially
in
women
and
children
3. Weak
health
policies,
systems
and
services
4. Links
with
maternal
and
children
services
not
yet
a
rouEne
5. Un-­‐engaged
non-­‐state
pracEEoners,
NGOs,
FBOs
and
communiEes
6. MDR-­‐TB
care
and
cure
inadequate,
especially
among
PLHIV
7. Social
and
economic
determinants
maintaining
TB
8. Research
awakening
needed
for
new
diagnosEcs,
drugs
and
vaccines

14. Challenge:
TB
as
a
cause
of
maternal
and
child
morbidity
and
mortality
ü TB
causes
1-­‐16%
of
all
inferElity
and
15-­‐40%
of
tubal
inferElity
ü Facility
based
studies:
12-­‐14%
of
all
TB
cases
are
in
children
ü TB
prevenEon
for
child
contacts
not
pracEced
ü Studies
from
SS
Africa
and
India
showed:
– TB
as
a
cause
of
all
maternal
mortality:
6-­‐15%
– TB
as
a
cause
of
indirect
maternal
mortality:
15-­‐34%
