Which of the following is NOT considered a major infectious disease?

Hypertension is classified as a chronic non-communicable disease rather than an infectious disease. It primarily relates to the body's inability to regulate blood pressure over time, often due to lifestyle factors, genetics, or other health conditions. In contrast, COVID-19, flu (influenza), and tuberculosis are all infectious diseases caused by pathogens such as viruses and bacteria. These diseases can be transmitted from person to person and can lead to outbreaks in populations, which is why they are classified as major infectious diseases. Understanding the distinction between infectious and non-infectious diseases is crucial in health education, as it influences prevention strategies and health policies.
