Many people have lost loved ones due to awful diseases such as silicosis and tuberculosis. Silicosis is a lung disease that is incurable. It is caused by inhaling silica dust from gold-bearing rocks over a prolonged period. It causes shortness of breath, coughing, fever and chest pains. People often confuse silicosis with tuberculosis (TB). Tuberculosis is an infectious disease caused by bacteria. Like silicosis it also affects the lungs but can affect other parts of the body as well.
