Very complex question. Some disease are genetic, some are unknown, some are caused by a single mutations in the DNA. Infectious diseases are spread by the bacteria, viruses, fungi etc that cause them and are spread by various routes (sneezing, blood, fecal oral route, contaminated food etc). The easiest one to catch is a cold virus--have someone sneeze your way.
