Health is defined as the absence of illness from physical, psychic, and social perspectives. There are five main types of illnesses: infection, congenital, hereditary, deficit, and chronic. Infectious diseases spread through four phases - incubation, apparent disease, convalescence, and recovery - but the body fights infections through internal defenses like non-specific and specific defenses and external defenses like vaccination. Non-infectious diseases include cancer and drug addiction which can cause physical, psychological, and social consequences.
