**Question:** The distance from airpo or seapo which has to be free from mosquitoes is -

A. 0 meters
B. 1 meter
C. 2 meters
D. 3 meters

**Correct Answer:**

**Core Concept:** Mosquitoes are primarily attracted to humans for blood feeding during the nighttime, and their breeding sites are usually close to stagnant water sources.

**Why the Correct Answer is Right:** The correct answer is **D. 3 meters** because it considers the typical behavior of mosquitoes to come in search of humans from a certain distance, typically within 10 meters. Mosquito breeding sites are often found within close proximity to human habitats, usually within 3 meters.

**Why Each Wrong Option is Incorrect:**

A. 0 meters: Mosquitoes can fly up to a maximum distance of around 100 meters, so 0 meters is incorrect as it assumes mosquitoes cannot fly and is too short a distance.

B. 1 meter: While mosquitoes can be attracted to humans within a meter, this is too short a distance considering their flying range and the possibility of breeding sites being within this range.

C. 2 meters: Similar to option B, 2 meters is too short a distance, considering mosquitoes' flying range and potential breeding sites.

**Why is it important to keep a distance from mosquito breeding sites and mosquitoes:** Mosquitoes are vectors for various diseases like malaria, dengue, and Zika virus, to name a few. By keeping a distance from mosquito breeding sites (e.g., stagnant water bodies near human habitats) and maintaining a safe distance from mosquitoes (within 10 meters), we can minimize the risk of mosquito-borne diseases and their associated complications.

**Clinical Pearl:** The World Health Organization (WHO) recommends a minimum distance of **10 meters** from potential mosquito breeding sites to avoid exposure to mosquitoes and their associated diseases. This helps in maintaining personal hygiene and public health measures.
