STREP THROATSTREPTOCOCCAL PHARYNGITIS STREPTOCOCCAL TONSILLITIS

What is it?• Bacterial infection in throat and tonsils• Throat becomes inflamed and irritated• Primarily caused by : Group A streptococcal bacteria• Most common from ages 5-15• Typically, sore throats are caused by viral infections—not bacteria.

Discovery• Streptococci bacteria were observed by Anton Van Leeuwenhoek in 1674 with his trusty microscope.

• In 1904 Friedrich Reinhardt Strep discovered it as the cause of the throat illness, hence its name.

How can it be diagnosed/identified? SYMPTOMS:• Severe and sudden sore throat with no cold symptoms• red and white patches, or coating, in throat• pain and difficulty swallowing• swollen glands/lymph nodes in neck• red and enlarged tonsils• Fever over 101 degrees Fahrenheit• loss of appetite and nausea, headache, belly pain• Skin rash (scarlet fever)

Tests• Physical exam (swollen lymph nodes, presence of symptoms…)• Rapid strep test-analyzes bacteria in throat to see if strep is the cause. • Throat culture-analyzes cells in back of throat. The cells are placed in container with substances that promote strep growth. If strep bacteria do grow, the culture is positive. • Throat culture is more accurate.

How can you get it? O_O• Strep throat is highly contagious!• You can get it by breathing in droplets with strep bacteria in the air, usually when a person who has strep throat breathes, coughs, or sneezes.

• Strep throat usually goes away in 3 to 7 days. • Doctors may suggest over the counter relief medicine.• May give antibiotics to prevent spread. • Some home remedies: Drink water, sleep, throat lozenges, herbal tea, etc. • BUT…complications may occur if infection spreads to other parts of body.
