This document discusses microorganisms and their impact on health. It describes how microorganisms can cause illnesses like infectious diseases and deficiencies, but also lists some beneficial effects. Microorganisms are categorized as bacteria, viruses, or fungi. Bacteria are the smallest and most abundant, found everywhere, while viruses depend on other organisms to multiply. Fungi grow in damp areas. Infectious diseases from microorganisms like cholera, typhoid fever, tuberculosis, and ringworm are described along with their causes and effects. The document also notes that beneficial bacteria live in the human body in places like the skin, nose, stomach and intestines where they protect against harmful microorganisms.
