Tuberculosis cause

Tuberculosis cause,

people, suffering, from active pulmonary, TB, cough,

sneeze, speak, or spit, they expel, infectious, aerosol,

droplets,a single sneeze, can release, up to 40,000, drople,

Each one of these droplets, may transmit, the disease,

since the infectious, dose of TB, is very low, and inhaling

fewer, than ten bacteria, may cause, an infection.

A person with active, but untreated, TB, can infect, 10–15

other people,are at risk,

include people, in areas where TB is common,

people who inject, drugs, using unsanitary, needles,

children, exposed, to adults with TB,

Transmission, can only occur, from people, with active,

— not latent — TB.

Exposure to M.T.B. strain

the effectiveness, of ventilation, the duration, of exposure,

anthe virulence, of the M.T.B strain.

The chain, of transmission,

can, be broken by isolating, patients, with active disease, and

starting, effective, anti-tuberculous, therapy.

After two weeks of such treatment,

people with non-resistant, active TB, generally cease, to be

contagious infection.

TB Infection

If someone, does become infected,

then it will take, at least, 21 days, or three, to four weeks,

before, the newly, infected, person, can transmit, the disease,

to others.

TB, can also be transmitted, by eating meat, infected, with TB.

Mycobacterium bovis, causes, TB, in cattle.

Importantly, bacteria, are not always eliminated, within the

granuloma, but can become, dormant, resulting in a latent,

infection.

Development of Abnormal cell Death

Another, feature, of the granulomas, of human, TB, is the

development of abnormal cell death,

also called necrosis,

in the center, of tubercles,

to the naked eye,

this has the texture,of soft, white, cheese, and was termed,

caseous necrosis.

If TB, bacteria, gain entry, to the bloodstream,

body, and set up, many foci, of infection,

all appearing, as tiny white tubercles ,in the tissues.

This severe, form, of TB disease,

common, in infants, the elderly, and is called,

miliary tuberculosis.

Patients, with this disseminated, TB, have a fatality, rate,

near100%, if untreated.

If treated, early, the fatality, rate,

is reduced to near10%
