Explanation:

The severity of the disease manifestation depends on various factors such as the number of microbes causing the disease, the nutrition we have, the organ infected/affected, the strength of the infectious agent, etc. However, among these factors, the number of microbes causing the disease plays a major role.

Number of Microbes Causing the Disease:

The severity of the disease manifestation is directly proportional to the number of microbes causing the disease. The higher the number of microbes, the more severe the disease manifestation will be. The number of microbes required to cause the disease varies depending on the type of microbe and the host's immune system's strength. For example, a few bacteria may be enough to cause a severe infection in a person with a weakened immune system, while a healthy person may require a higher number of bacteria to cause the same infection.

Other Factors:

Although the number of microbes causing the disease is the most crucial factor that determines the severity of the disease manifestation, other factors also play a significant role. These factors include:

- Nutrition: Proper nutrition is essential for maintaining a healthy immune system. A person with a healthy immune system can fight off infections better than a person with a weakened immune system due to poor nutrition.

- Organ Infected/Affected: The severity of the disease manifestation also depends on the organ infected/affected. For example, a bacterial infection in the lungs can cause severe respiratory problems, while the same infection in the skin may not be as severe.

- Strength of the Infectious Agent: The strength of the infectious agent also plays a role in determining the severity of the disease manifestation. Some infectious agents are more potent than others and can cause severe infections even in healthy individuals.

In conclusion, while the severity of the disease manifestation depends on various factors, the number of microbes causing the disease is the most crucial factor. Proper nutrition, the organ infected/affected, and the strength of the infectious agent also play a significant role in determining the severity of the disease manifestation.

Because the number of microbes in our body are smaller therefore the symptoms of a disease are lesser in amount ..
