Laryngitis is most commonly caused by which type of infectious agents?

• A. Parasitic
• B. Fungal
• C. Bacterial
• D. Viral

Answer: (D)

Laryngitis is most often caused by viruses that inflame the laryngeal lining after an upper respiratory infection. This viral inflammation makes the vocal cords swell and mucus-rich, leading to hoarseness or loss of voice. Bacteria can cause throat infections, but laryngitis itself is much less commonly bacterial; when bacteria are involved, it's not the typical scenario and treatment may include antibiotics if bacterial infection is suspected. Fungal and parasitic causes are rare, usually occurring in people with certain risk factors or immune suppression. So, the frequent culprit is viral infection.
