Strep throat is a disease that causes a sore throat (pharyngitis). It is an infection with a germ called group A streptococcus bacteria.
Pharyngitis - streptococcal; Streptococcal pharyngitis; Tonsillitis - strep; Sore throat strep
Strep throat is most common in children between ages 5 and 15, although anyone can get it.
Strep throat is spread by person-to-person contact with fluids from the nose or saliva. It commonly spreads among family or household members.
Symptoms appear about 2 to 5 days after coming in contact with the strep germ. They may be mild or severe.
Common symptoms include:
Other symptoms may include:
Some strains of strep throat can lead to a scarlet fever-like rash. The rash first appears on the neck and chest. It may then spread over the body. The rash may feel rough like sandpaper.
The same germ that causes strep throat may also cause symptoms of a sinus infection or an ear infection.
Most sore throats are caused by viruses, not bacteria.
A sore throat should be treated with antibiotics only if the strep test is positive. Antibiotics are taken to prevent rare but more serious health problems, such as rheumatic fever.
Penicillin or amoxicillin are most often the first drugs to be tried.
The following tips may help your sore throat feel better:

Symptoms of strep throat most often get better in about 1 week. Untreated, strep can lead to serious complications.
Complications may include:
Contact your provider if you or your child develops the symptoms of strep throat. Also, call if symptoms do not get better within 24 to 48 hours of starting treatment.
Most people with strep can spread the infection to others until they have been on antibiotics for 24 to 48 hours. They should stay home from school, daycare, or work until they have been on antibiotics for at least a day.
Get a new toothbrush after 2 or 3 days, but before finishing the antibiotics. Otherwise, the bacteria can live on the toothbrush and reinfect you when the antibiotics are done. Also, keep your family's toothbrushes and utensils separate, unless they have been washed.
If repeated cases of strep still occur in a family, you might check to see if someone is a strep carrier. Carriers have strep in their throats, but the bacteria do not make them sick. Sometimes, treating them can prevent others from getting strep throat.
Summary: This is a Phase 2 clinical study to support the use of AFX3772 in healthy infants for the prevention of pneumococcal disease. The purpose of this study is to determine the safety, tolerability, and immunogenicity of 3 different dose levels of AFX3772 compared with PCV13. Infants approximately 2 months of age will be enrolled and receive 4 doses of study vaccine over 8 protocol-defined visits spann...
Summary: This study will evaluate the safety, tolerability, and immunogenicity of a pneumococcal 21-valent conjugate vaccine (V116) in pneumococcal vaccine-naïve adults 18 to 49 years of age. The primary study hypothesis is that all 3 lots of V116 are equivalent as assessed by the serotype-specific opsonophagocytic activity (OPA) Geometric Mean Titers (GMTs) at 30 days postvaccination for all serotypes inc...
