Question

Acute Hemorrhagic Conjunctivitis is caused by which of enterovirus type ?

• A. 69
• B. 68
• C. 70
• D. 71

Answer 1

The Correct Option is C

Step 1: Picture the disease - a sudden red, swollen, bleeding-looking conjunctiva spreading fast through a community. That clinical entity is acute hemorrhagic conjunctivitis.
Step 2: Its viral causes are Coxsackievirus A24 variant and Enterovirus 70. Since A24 is not in the list, the answer must be the enterovirus serotype, $EV70$.
Step 3: EV70 is famous for epidemic eye outbreaks and an uncommon delayed lumbosacral radiculomyelitis, both useful clues linking the number 70 to the eye.
Step 4: Rule out the neighbours - 68 is a respiratory virus tied to acute flaccid myelitis, 71 drives hand-foot-and-mouth disease and CNS disease, and 69 is not the conjunctivitis agent.
\[\boxed{70}\]
