While the illness, Primary Complex, may not seem injurious upon analysis, it may develop into tuberculosis (TB) when your child’s immune system is down.
What is Primary Complex?
Children uncovered to Mycobacterium tuberculosis may sometimes expand a tuberculosis (TB) infection called Primary Complex. The most common route of illness is through breathing. A person with active TB coughs up the germ and it is inhaled by a healthy child. The TB then travels to the lungs. The immune system kicks in and “quarantines” the germ at the local site and at the neighboring lymph nodes.The child remains healthy and usually has no symptoms. They may remain symptom free until their immune system declines and the disease becomes active.
How do you diagnose Primary Complex?
As most patients have no warning sign, they only find out they have Primary Complex through a tuberculin skin test (also called a Mantoux test or PPD test). A little amount of purified protein derived (a.k.a. PPD) of the TB germ is injected superficially into the forearm. An itchy, raised, red reaction past a certain size (these changes is considered positive. In 20% of cases, a PPD test will be negative in patients with TB infection. Other times, children will have a falsely positive PPD test because they had the BCG BCG (Bacillus Calmette-Guerin) vaccine.
