Document Content and Description Below

Immune System 101 ● The 3 lines of defense of your immune system ○ 1. Physical and Chemical Barriers (Innate Immunity) ■ First line of defense ■ Physical Barriers: Skin, Mucous membranes (lining throat, nose, etc.), Hair, Cilia, Urine, Defecation and vomiting ■ Chemical Barriers ● Lysozyme- an enzyme produced in tears, perspiration, and saliva (Break down cell walls, acts as an antibiotic), Gastric juice, Acidity on skin inhibits bacterial growth ○ 2. Nonspecific Resistance (Innate Immunity) ■ The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals ● Phagocytic cells ingest and destroy all microbes that pass into body tissues. ● Inflammation is a localized tissue response that occurs when your tissues are damaged and in response to other stimuli. Inflammation brings more white blood cells to the site where the microbes have invaded. The inflammatory response produces swelling, redness, heat, pain - - - - - - - - - - - - -- - - - - - - - - - - - - - create a specific response, why are we waiting on a Corona Virus vaccine? ○ Vaccines help develop immunity by imitating an infection. This type of infection, however, almost never causes illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity. It used to take a long time to make vaccines, because scientists had to isolate and grow the virus in the lab. But now, it's possible to skip that step altogether and build a vaccine based on a virus' genetic sequence. ● Who should be the most concerned with the COVID- 19? ○ Older adults ○ People who have serious chronic medical conditions like: ■ Heart disease ■ Diabetes ■ Lung disease ● Any other information on how you can help fight the stigma/ ignorance in our society concerning COVID-19? ○ People can fight stigma and help, not hurt, others by providing social support. Counter stigma by learning and sharing facts. Communicating the facts that viruses do not target specific racial or ethnic groups and how COVID-19 actually spreads can help stop stigma.
