Which virus is responsible for causing common cold?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Rhinovirus.
The virus most commonly responsible for causing the common cold is: Rhinovirus.
Rhinoviruses are the leading cause of upper respiratory tract infections, especially the common cold. They belong to the Picornaviridae family and are highly contagious, spreading through airborne droplets, direct contact, or contaminated surfaces. These viruses primarily infect the nose and throat, leading to symptoms like sneezing, sore throat, runny nose, and mild fever. While over 200 viruses can cause cold-like symptoms, rhinoviruses account for 30–50% of all cases.
Other Options :
- Influenza: Causes the flu, a more severe respiratory illness with high fever, body aches, and fatigue.
- Coronavirus: Some strains (like OC43, 229E) can cause cold symptoms, but they are less common than rhinoviruses.
- Hepatitis A: Affects the liver and is transmitted through contaminated food or water, not linked to respiratory infections.
