Which one of the following is not a viral disease? (a) Dengue (b) AIDS (c) Typhoid (d) Influenza

Answer: c) Typhoid

Explanation: Typhoid is a bacterial infection that is spread primarily through contaminated food or water. Poor hygiene conditions can also spread it. High fever, loss of appetite, and diarrhoea are the most common symptoms of this illness. The bacterium that causes this sickness is Salmonella typhi and humans are the only ones who can get it. In the early 1900s, the first case of typhoid fever was documented in the United States.

Bacteria enter the human body through contaminated meals and water, where they subsequently enter the human body’s intestinal cells. It then spreads throughout the body after passing through the bloodstream and destroying the lymphatic system. The white blood cells in the liver and the bone marrow are the principal carriers of this bacterium.
