Strep Throat: Infections

Strep throat is caused by the bacterium Streptococcus pyogenes.[5][6][7][8] It is spread by direct, close contact with an infected person via respiratory droplets. In one study, 114 patients with positive throat cultures and a presence of group A beta-hemolytic streptococci (GAS) were studied to see transmission within their families through pillow cases, toys, and patients tooth brush. Of those 114 patients studied 50 patients received hygiene instructions to follow and 64 were not given hygiene instructions. The percent of culture-verified recurrences was 35%.[9] Casual contact can result in transmission like the study that was done on transmission in households by two Norwegian health centers. 127 patients with positive throat cultures and their families were studied. Four weeks after the beginning of the study, other members of the household were asked if they had any positive throat culture since the beginning of the study; In 30 households there was one more case of infection, in 22 households 2 more cases, 6 households with 3 cases, and 2 households with 4 cases.[10] Rarely, contaminated food, especially milk and milk products, can result in outbreaks.

Strep throat infections are spread person-to-person. Humans are the natural reservoir of this bacteria. The nose and back of the throat are the main sources of carriage of this bacteria. The skin and feces are potential sites. Aerosolized upper respiratory mucus serves as the primary source of the strep germ spreading to others. Direct contact with infected nose and throat tissues (by kissing) is of less importance as is contact with contaminated objects, such as toothbrushes.

Strep throat is an infection caused by the bacterium, Streptococcus pyogenes. It is spread through person-to-person contact with contaminated nasal secretions or respiratory droplets. Symptoms usually occur within three days of exposure. Patients may experience throat inflammation and pain, swollen lymph nodes in the neck, fever, headache, chills, body aches, muscle aches and abdominal pain. Inside, the throat may look red with white or yellowish spots.

Strep throat is an infection of the throat caused by group A streptococci bacteria. These bacteria can cause inflammation and infection in a variety of areas throughout the body, including the respiratory system, skin and vital organs. In addition, damage to the heart valves (in rheumatic fever) and kidneys (glomerulonephritis) sometimes occurs.

The first steps in diagnosing strep throat are a patient history and physical examination. The doctor will ask if the patient has been around other people with the infection. He or she will ... examine the patient's throat and chest. The doctor will also try to eliminate other potential causes of the symptoms, such as bronchitis (see bronchitis entry) or sinus infection.

There is a characteristic rash that sometimes accompanies strep throat. This appears as fine, red pimples all over the trunk (chest, abdomen and back) that feel rough, almost like sandpaper and may look like a sunburn. This rash, with strep throat, is called Scarlet Fever. Do not worry; this is not serious like it used to be. It is simply the body reacting to a toxin produced by the strep. It does not mean the infection is more serious than strep throat without a rash, and it goes away with treatment.
