Sore Throat
What is Sore Throat or Upper Respiratory Tract Infection?
The upper respiratory tract consists of the nose, nasal cavity, larynx, and trachea, as well as some of the sinuses and air cells. Upper respiratory tract infections include the common cold (rhinitis), influenza, laryngitis (inflammation of the voice box), pharyngitis (sore throat), sinusitis, tonsillitis, and croup (in children).
Causes of Sore Throat
There are over 200 viruses that can cause upper respiratory tract infections. These types of viruses are extremely contagious and are spread by direct contact, such as shaking hands, sharing food or drink, and kissing. They can also be spread through coughing and sneezing. A virus can be spread from the hands to the upper respiratory tract by touching the eyes, nose, or mouth.
Symptoms of Sore Throat
The common cold has symptoms ranging from sneezing, coughing, and runny nose, to congestion, headache, and sore throat. Colds may or may not include a fever. Most common colds last for about one week. Influenza begins suddenly and causes more discomfort than a cold.
Diagnosis of Sore Throat
Upper respiratory tract infections are diagnosed according to the types and durations of symptoms. Cold symptoms that last for months, but are not caused by sinus problems, may actually be allergy-related.
