being a carrier means you have diesease but it's not affecting you. and it also means you may pass it on to your son/daughter. and being infected is actually having the diesease and it having an affect on you. but if your just a carrier your ok, but your kids may not be.

some are known to just have the disease..and they would never have any of the symptoms..... and they are carrier...they can not spread it.... while the contagious one ,would not only have the disease but be able to spread it to others...

A carrier is somebody that has contrcted TB at some point in their lives, but it is not active and is not spread by the person. A contagious person usually shows other signs of TB and can spread the disease through the air by coughing. If you are a carrier, it just means that you can't donate blood anymore.

When you are a carrier of tb it means that the disease is laying dormant in your body. When you are suffering from symptoms of the disease, then you are contagious.

i think it means the same thing... if you are diagnosed with tuberculosis -- you are both a carrier and you are also contagious.

Basically a carrier has the bacterium in his body, but cannot current spread it (and generally has no overt symptoms), while someone who is contagious can spread it (and is generally symptomatic). Tuberculosis is one of the diseases that can remain dormant in the body for a long time, but reactivate if the immune system gets weakened. It is caused by a bacterium, Mycobacterium tuberculosis, that gets into the lungs and is attacked by immune system cells called macrophages. The macrophages are supposed to destroy the bacterium (as they do many other bacteria), but (through an unknown mechanism) the bacterium is able to prevent the macrophage's bacterium-killing machinery (called an endosome) from acidifying and destroying the bacterium. However, the macrophages (along with antibodies) are able to wall the infection off in a tubercle-- a hard ball within the lung-- where the infection cannot do active harm. However, if the immune system is weakened, the tubercle can break down, the infection spread, and the person become sick and contagious again
