 Understanding Your Immune System and How it Affects Your HealthThe immune system is responsible for protecting the body against infection. Its major components include lymph nodes, bone marrow, spleen, thymus gland and tonsils (if you still have them). There are two types of immunity present in our bodies: innate and adaptive. Innate immunity is present at birth and provides an initial barrier against microorganisms. You acquire adaptive immunity later in life, such as after fighting off an infection. The name says it all: Adaptive immunity "remembers" these invaders and adapts to recognize and ward them off again should they recur. According to the National Institutes of Health, flu outbreaks usually begin suddenly and occur mainly in the late fall and winter. It can spread through communities, creating an epidemic. During the epidemic, the number of cases peaks in about 3 weeks and subsides after another 3 or 4 weeks. Half of the population of a community may be affected. Because schools are an excellent place for flu viruses to attack and spread, families with school-age children have more infections than other families, with an average of one-third of the family members infected each year. You'll know if you have the flu versus a cold because like a cold, the flu gives you a sore throat and a stuffy nose. But the flu also brings with it body aches, chills and usually a fever.
