Tuberculosis: a consuming disease
Now that we have talked about the different types of tuberculosis, their source and symptoms, let's have a glance at how TB can be prevented, distinguished and treated.
It is important to know that 8 million people are added to the long list of the "TB affected" anually. It is estimated that about 10-15 million people are suffering TB just in the U.S. The only way this disease can be passed on is via air particle transmition. Of course there are a few factors that can increase the vulnerability of a person in regards with TB. Some of these factors may include alcohol and drug intake, poor immune system, diabetics, those with AIDS, and also some races. Unlike AIDS which is transmitted via contact, TB is transmitted only if infected air particles are inhaled. And because noone is aware of the clinical situation of all the surounding people and noone can detect if the atmosphere is TB infected or not, anyone can fall in the footpath of TB.
But the search for vaccines had started as early as the early 19th century and even untill now, many countries use the BCG vaccination programme when a child is born. The BCG aids the body very weakly in terms of TB and although it can prevent minor damage, it is not a reliable programme. But studies are taking place and new and much more effective vaccines are on the verge of flowing through the body of the public; such as the MVA85A.
