This is asymptomatic and not infectious, so it cannot be passed on
however, there is a 10% lifetime chance that the bacteria can reactivate and cause
TB disease.
Activated LTBI is most likely to occur in the first two years of infection,
or
in patients who are immunocompromised by other illness or old age (Williams, 2008).
If the immune system is unable to kill or contain the bacteria, they can continue to
grow and multiply, causing sickness.
This is called active TB disease
