Overview of Tuberculosis

TM

Tuberculosis

• Caused by bacteria Mycobacterium tuberculosis

• Usually attacks the lungs, but can affect any part of

the body

• TB disease can be fatal

• Once the leading cause of death in the United States

TM

Transmission

The dots in the air

represent droplet

nuclei containing

tubercle bacilli

• When a person with infectious TB disease coughs, sneezes,

speaks, or sings, tiny particles containing M. tuberculosis

(droplet nuclei) may be expelled into the air

• If another person inhales the droplet nuclei, transmission may

occur

TM

Tuberculosis Transmission

• Expelled when person with infectious TB coughs,

sneezes, speaks, or sings

• Close contacts at highest risk of becoming infected

• Transmission occurs from person with infectious

TB disease (not latent TB infection)

Active TB Disease vs.

Latent TB Infection

Active TB Latent TB Infection

• TB germs in the body

• May be infectious (before

treatment)

• Symptoms of TB (e.g.,

cough)

• An active “case” of TB

• Treatment needed to cure

disease

• TB germs in the body, but

latent (dormant) state

• NOT infectious

• No symptoms

• Not a “case” of TB

• Treatment may be provided

to prevent transition from

TB infection to TB disease

TM

Symptoms of TB

Productive, prolonged cough

Fever

Chest pain

Hemoptysis

Chills

Night sweats

Weight loss

TM

Global TB

• One-third of the world’s population is infected

with TB

• Someone in the world is newly infected with TB

bacilli every second

• Each year, 9 million people around the world

become sick with TB

• In 2005, there were 1.6 million TB-related deaths

worldwide from this curable disease

• TB is the leading killer of people who are HIV

infected

On average an

untreated

person with

infectious TB

infects between

TB in the African-American

Community

TB in African Americans• While overall rates continue to decline in the U.S.,

TB continues to disproportionately affect racial

and ethnic minorities

• In 2005

– 82% of all reported TB cases occurred in racial

and ethnic minorities

– 45% of TB cases reported in U.S.-born persons

were among African Americans

– The TB case rate for U.S.-born blacks

(8.9/100,000) is more than 8 times higher than

the rate in U.S.-born whites (1.1/100,000)

TB/HIV Co-infection

• HIV is a significant risk factor for progression from

TB infection to TB disease

• TB disease is an AIDS defining illness

• Knowledge of HIV/TB co-infection is important for

patient management

TM

HIV Infection Among Reported TB

Cases, 2005

• All TB cases

– Estimated 9% HIV/TB co-infection

– Estimated 31% with unknown HIV status

• TB cases in blacks

– Estimated 18% HIV/TB co-infection

– Estimated 21% with unknown HIV status

*Excludes California data

TM

TB and HIV• CDC has recommended HIV counseling and

testing of all TB patients since 1989

• In September 2006, CDC released guidelines recommending HIV screening for patients in all health-care settings (including TB clinics) after being notified that testing will be performed unless the patient declines (opt-out screening)

• Knowing the HIV status of TB patients is necessary for optimal patient management for contacts, and persons with LTBI or TB disease

• CDC has TB education and training resources

available free of charge
