Question

Higher Order Thinking Skill.

Tejas suffered from typhoid while, Sachin suffered from tuberculosis. Which disease could have caused more damage and why?

Answer in Brief

Solution

Typhoid is a food and water-borne disease which affects the intestines. There are good drugs available for its treatment. If the patient reports to the doctor on time, it can be treated safely. Typhoid vaccine is also available that can protect against further attacks.

Whereas, Tuberculosis is a very tricky disease. Though it basically infects the lungs, it can spread to other parts of the body such as bones, intestines, etc. Another complication of TB is that, once infected, the Mycobacterium remains dormant in the body even after adequate treatment. Whenever the immunity of the patient goes down, TB can resurface again. Therefore, Tuberculosis causes more damage when compared to Typhoid.
