Hand foot mouth disease is characterized by a) Cause miniepidemic in school b) I.P. -3 – 10 Days c) Transmitted by virus d) C/F similar test seen in cows

**Core Concept**
Hand-foot-and-mouth disease (HFMD) is a common viral illness primarily affecting children, characterized by a distinctive rash on the hands and feet, mouth sores, and fever. It is caused by various enteroviruses, most commonly coxsackievirus A and enterovirus 71.

**Why the Correct Answer is Right**
HFMD is indeed transmitted by viruses, specifically enteroviruses, which are highly contagious and can spread rapidly in close-knit environments such as schools. The incubation period of HFMD typically ranges from 3 to 10 days, during which time the individual may be asymptomatic but still contagious. The rapid spread of HFMD in schools can lead to mini-epidemics.

**Why Each Wrong Option is Incorrect**
**Option A:** While HFMD can cause mini-epidemics in schools, this is not the most characteristic feature of the disease.
**Option B:** The typical incubation period of HFMD is indeed between 3 and 10 days, but this is not the most distinctive aspect of the disease.
**Option D:** The clinical features of HFMD are not similar to those seen in cows, which are not relevant to this disease.

**Clinical Pearl / High-Yield Fact**
HFMD is highly contagious and can be spread through direct contact with an infected person's feces, saliva, or mucus, as well as by touching contaminated surfaces and then touching one's mouth or eyes.

**Correct Answer: C**. Transmitted by virus
