Which of the following is a non-infectious disease ?

Question

Accepted Answer

Cancer is classified as a non-infectious disease, which is why Option 2 is the correct answer. Non-infectious diseases are not caused by pathogens and cannot be transmitted from one person to another. Instead, they may result from genetic factors, lifestyle choices, environmental exposures, or a combination of these. Cancer fits this description as it involves the uncontrolled growth and spread of abnormal cells in the body, which can be influenced by genetic predispositions, lifestyle factors such as smoking and diet, and environmental exposures like radiation or carcinogenic chemicals.

Now, let's examine why the other options are incorrect:

1. **AIDS**: Acquired Immunodeficiency Syndrome (AIDS) is an infectious disease caused by the Human Immunodeficiency Virus (HIV). It is transmitted through bodily fluids, making it an infectious disease.

3. **Corona**: Referring to the coronavirus, specifically COVID-19, this is an infectious disease caused by the SARS-CoV-2 virus. It spreads from person to person through respiratory droplets, making it infectious.

4. **Common cold**: The common cold is an infectious disease caused by various viruses, most commonly rhinoviruses. It spreads easily from person to person through respiratory droplets, making it an infectious disease.

In summary, Cancer is the only option among the given choices that is a non-infectious disease, as it is not caused by a pathogen and cannot be transmitted between individuals.
