    1. The document discusses communicable diseases and how they are transmitted from one host to another. It covers topics like pathogens, modes of transmission, and the chain of infection. 2. Key terms are defined, like bacteria, viruses, parasites, and the different modes of transmission such as direct contact, indirect contact, airborne, and fecal-oral. 3. The chain of infection is explained as involving a pathogen, reservoir, portal of exit and entry, and a susceptible host. Practicing good hygiene and eating nutritious foods can help prevent the spread of communicable diseases.
