My friend has been complaining about a sore throat for the past few days. What could be causing this?

The most likely cause is an infection of the tonsils or adenoids, which can lead to a sore throat. This type of infection is usually caused by bacteria and viruses that are spread through saliva and mucus from the mouth. Other causes include smoking and allergies, both of which can irritate the throat and make it more prone to infections.
