Question

Describe infectious and non-infectious diseases.

Answer 1

Hint: Infectious diseases are those that have high potentials of being spread through the communities. On the other hand, non-infectious diseases are just the opposite of infectious diseases. The infectious diseases are considered more contagious than noninfectious diseases. This is because they affect the population in mass numbers. For example, coronavirus is much more lethal than diabetes.

Complete step by step answer: A disease is referred to as a disability of the body to work properly. The disease is a condition that causes the human body or its parts to function abnormally or defectively.
-A diseased person is called ill. The illness is a result of a foreign infection in the body or by the body’s dysfunction. On the other hand, a person is said to be healthy if he/she has a stable physical and mental status.
-Diseases are classified into two categories based on their potential to spread from one infected or ill person to one healthy person. These categories are infectious diseases and non-infectious diseases. To understand their differences let us go through each of them in detail.
INFECTIOUS DISEASES
Infectious or communicable diseases are those that have a high risk of transfer from an infected or ill person to a healthy person. Infectious diseases are mainly caused by pathogens. Pathogens are microbes that live inside the human body making it as host and derive their nutrition from the body. These are bacteria, fungi, or viruses mainly. They spread mostly by droplets of mucus secreted by the infected person. A dreaded disease which is COVID-19 is caused by a coronavirus that spreads very rapidly through air droplets and by physical contact with infected persons and areas. Thus, infectious diseases pose more threat than non-infectious diseases.
NON-INFECTIOUS DISEASES
Non-infectious diseases are those that do not spread easily. They are also called non-communicable diseases. They are normally caused by the body’s internal dysfunction. Like diabetes, the sugar levels in the blood get imbalanced due to the dysfunction of insulin-producing cells that regulates the sugar level in the bloodstream. They do not spread by any physical contact or any infectious droplet inhalation. The only possible spread is through rare genetics.

Note: The cures for infectious diseases are not much effective when compared to their preventive measures. Thus the infected persons should take all the safety and preventive measures to resist the spread of disease.
