Pharyngitis can cause the pharynx (the throat) tissue to become swollen and reddish. Some people can develop a mild fever and have some difficulties speaking or swallowing food. swollen Lymph nodes and tonsils may enlarge and become tender. Those affected may feel excessively tired.
Laboratory studies can detect group A streptococci (rapid antigen detection). Other diagnostic tests can include throat cultures or the Mono
spot test. A health-care professional may help you determine the cause
of your sore throat. In addition, some doctors use the specific set of
criteria (Centor criteria) to determine the likelihood of a person
getting strep throat (Streptococcal pharyngitis).
How is sore throat spread?
Sore throat is transmitted from one person to another by bacteria or
viruses in the infected person's saliva, mucus and/or nasal discharge.
People that are not infected just need to come in contact with these
substances directly or indirectly by touching contaminated objects such
as hairbrushes, towels, or toothbrushes.
How will I know if I'm cured of
a sore throat?
Sore throat caused by viruses is usually contagious as long as
symptoms are present. Once the symptoms disappear, the person is usually
no longer contagious and is"cured" of viral pharyngitis. However, the
person may still be susceptible to other types of viruses that can cause
pharyngitis. Bacterial pharyngitis usually is also contagious as long
as symptoms are present but, in contrast to viral pharyngitis,
antibiotics may reduce the time span of infection, and the individual
becomes no longer contagious about 24 hours after taking an effective
antibiotic.
