Question

Which of the following Climatic Zones (as per WHO Criteria) refers to “hot and humid climate”?

• A. Zone I
• B. Zone II
• C. Zone III
• D. Zone IV

Answer 1

The Correct Option is D

In the context of pharmaceutical management, understanding climatic zones is crucial for determining the storage and stability conditions of pharmaceuticals. The World Health Organization (WHO) classifies regions into different climatic zones to address this issue. These zones are based on temperature and humidity conditions, as they significantly affect the shelf life and efficacy of medicines.

The WHO climatic zones are as follows:

1. Zone I: Temperate climate.
2. Zone II: Subtropical and Mediterranean climate.
3. Zone III: Hot and dry climate.
4. Zone IV: Hot and humid climate.

The question asks for the climatic zone that refers to a "hot and humid climate." According to the WHO classification:

• Zone IV is specified for regions characterized by high temperatures and high humidity.

Therefore, the correct answer is Zone IV, as it corresponds to areas with a hot and humid climate. Such classification is crucial for pharmaceutical products to ensure stability and efficacy while being stored and transported under appropriate conditions.

This classification helps pharmaceutical companies to design suitable packaging, storage, and distribution strategies to maintain the integrity and safety of the medicines across different climates worldwide.
