Normal microbiota/ flora when microorganisms establish a more or less permanent residence in the body but they do not produce any disease under normal conditions, they just chill in your body. Transient microbiota may be present for several days/weeks/months and then disappear. Symptoms: changes in body function; pain, malaise; subjective changes (no one else observes them) Signs: objective changes (someone else can observe them), lesions, swelling, fever, paralysis. Syndrome: specific group of signs and symptoms that accompany a certain disease. Disease often classified in terms of how they behave within a host and within a given population. Communicable disease any disease that spreads directly or indirectly from one host to another. Chicken pox, measles, genital herpes, typhoid fever, and tuberculosis.
