Infectious disease and non-infectious disease?

An infectious disease can be spread from one person to another and is caused by a pathogen. Some infectious diseases are lethal and they tend to be acute. Infectious diseases are defined by the way you feel and some that are not lethal tend to last no longer than a few weeks. The symptoms of infectious diseases vary but the most common symptoms are fever, muscle aches, vomiting, and diarrhea. The common cold, flu, mumps, measles, and food borne illness are examples of infectious diseases.
A noninfectious disease cannot be spread from one person to another. They are not contagious and they are not caused by a pathogen. Noninfectious diseases tend to be chronic and asymptomatic meaning that they develop slowly over a long period of time and they are ongoing. Noninfectious diseases are caused by a combination of factors including genetics, lifestyle, and environmental factors. Some examples of noninfectious diseases are arthritis, osteoporosis, atherosclerosis, cancer, heart disease, hypertension, and type II diabetes.
