DOTS stands for Directly Observed Treatment, Short-course. It is a treatment strategy for patients suffering from tuberculosis (TB). DOTS is an effective and standardized approach recommended by the World Health Organization (WHO) to ensure proper treatment adherence and improve TB outcomes.
Option 1: Polio is a viral infection that affects the nervous system and can cause paralysis, but DOTS is not a treatment for polio.
Option 2: AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV). DOTS is not used in the treatment of HIV/AIDS.
Option 3: Hepatitis refers to inflammation of the liver, and DOTS is not used in the treatment of hepatitis.
Therefore, the correct answer is option 4 as DOTS is a treatment given to patients suffering from tuberculosis.
