Question

Which of the following is a pair of viral diseases?

• A. common cold, AIDS
• B. dysentery, common cold
• C. typhoid, tuberculosis
• D. ringworm, AIDS

Answer 1

The Correct Option is A

In this question, we need to determine which pair of diseases are both viral in nature. Let us evaluate each option:

1. Option 1: Common cold, AIDS
   • The common cold is caused by viruses such as rhinoviruses.
   • AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV).
   • Both diseases in this option are indeed viral.
2. Option 2: Dysentery, Common cold
   • Dysentery is primarily caused by bacterial infections (like Shigella) or amoebic infections (like Entamoeba histolytica), not viruses.
   • Therefore, this option is a mix of bacterial or protozoal and viral diseases.
3. Option 3: Typhoid, Tuberculosis
   • Typhoid is caused by the bacterium Salmonella typhi.
   • Tuberculosis is caused by the bacterium Mycobacterium tuberculosis.
   • Both diseases in this option are bacterial, not viral.
4. Option 4: Ringworm, AIDS
   • Ringworm is a fungal infection, not a viral one.
   • Although AIDS is viral, the pairing with a fungal infection makes this option incorrect.

Based on the analysis above, the correct answer is Option 1: Common cold, AIDS. Both are caused by viruses, fulfilling the requirement of the question.
