A larger number of microbes increases the risk that you will be infected. Your immune system may be able to fight off a smaller number, but a large number may overwhelm your defenses.
The weakening of the immune system increases the possibility of acquiring an infectious disease.
The two main categories of disease that microbes can deliver are infectious diseases, caused by pathogens such as bacteria, viruses, and parasites, and non-infectious diseases, caused by factors such as toxins produced by microbes or the body's immune response to the microbe.
