A sore throat can be caused by illnesses ranging from non-serious issues to COVID-19. However, it is a less usual symptom and may vary from person to person. In COVID cases, the virus enters the membranes associated with the nose and the throat, which can make them swell, leading to a sore throat. The pain and soreness felt by the patient are called ‘pharyngitis’. In the case of COVID-19, one may also experience other pre-dominating symptoms such as fever, dry cough and fatigue along with sore throat, which is missing in normal cold and flu.
