Fungi

Parasites

Ans.3) Infectious Disease : Infectious diseases are caused by pathogenic micro-organisms such as bacteria, viruses, fungi or parasites. These micro-organisms are contagious, meaning they can be transmitted from one person to another.

Examples of infectious diseases include the common cold, COVID-19, SARS and tuberculosis.

Non-infectious Diseases : Non-infectious diseases are not caused by pathogens and therefore cannot be spread from one person to another. Instead, non-infectious diseases are caused by factors such as GENETICS, malnutrition, environment and LIFESTYLE.

Examples of non-infectious diseases include cancer, Alzheimer’s disease and epilepsy.
