Why does COVID-19 cause a sore throat?

Inflamed throat tissue can feel dry, scratchy, raw, or painful when you swallow or talk. Coughing, mouth breathing due to a blocked nose, and dehydration may add to the irritation. Sore Throat is a very common presentation of COVID-19. Many other viral illnesses, allergies, reflux, dry air, and bacterial throat infections can produce similar symptoms.

Sip water regularly and choose warm or cool drinks according to what feels soothing. Soft foods can be easier to manage when swallowing is uncomfortable. Gargling with salt water may help some adults who can gargle safely. Avoid smoking and smoky environments, which can further irritate the throat. A pharmacist can advise on suitable lozenges or pain relief if you have other health conditions or take regular medicines.

Get urgent help if you are struggling to breathe, cannot swallow saliva, are drooling, have severe swelling of the mouth or throat, or become confused or faint. Seek a clinical review for a severe throat pain with rash, persistent high fever, one-sided swelling, dehydration, or symptoms that do not improve after the acute illness.

Explain whether pain is on one side, whether swallowing liquids is difficult, and whether you have hoarseness, reflux, cough, rash, or swollen neck glands. Ask if a throat examination or test is needed and which pain-relief option is appropriate for you.
