Potential complications include rheumatic fever and peritonsillar abscess. Signs and symptoms
The typical signs and symptoms of streptococcal pharyngitis are a sore throat, fever of greater than 38 °C (100 °F), tonsillar exudates (pus on the tonsils), and large cervical lymph nodes.Other symptoms include: headache, nausea and vomiting, abdominal pain, muscle pain, or a scarlatiniform rash or palatal petechiae, the latter being an uncommon but highly specific finding.Symptoms typically begin one to three days after exposure and last seven to ten days.Strep throat is unlikely when any of the symptoms of red eyes, hoarseness, runny nose, or mouth ulcers are present. It is also unlikely when there is no fever. Cause
Strep throat is caused by group A β-hemolytic Streptococcus (GAS or S. pyogenes). Humans are the primary natural reservoir for group A streptococcus. Other bacteria such as non–group A β-hemolytic streptococci and fusobacterium may also cause pharyngitis. It is spread by direct, close contact with an infected person; thus crowding, as may be found in the military and schools, increases the rate of transmission. Dried bacteria in dust are not infectious, although moist bacteria on toothbrushes or similar items can persist for up to fifteen days. Contaminated food can result in outbreaks, but this is rare. Of children with no signs or symptoms, 12% carry GAS in their pharynx, and, after treatment, approximately 15% of those remain positive, and are true "carriers". Diagnosis
A number of scoring systems exist to help with diagnosis; however, their use is controversial due to insufficient accuracy.
Tinea faciei is a fungal infection of the skin of the face. It generally appears as a photosensitive painless red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face. It may feel wet or have some crusting, and overlying hairs may fall out easily. There may be a mild itch. Treatment
Most infections can be treated with topical antifungal medication. Rarely, more extensive or long-standing infections may require treatment with oral antifungals. The infection will still be contagious between 24 and 48 hours of the first treatment. The ringworm should go away within 4–6 weeks after using effective treatment. See also
