What’s causing my sore throat?

Can I prevent a sore throat?

Sore throats can be contagious, depending on their cause. Therefore to reduce the risk of catching them, practice good hygiene by washing your hands thoroughly and frequently particularly before eating, after using the toilet and if you have just sneezed or coughed. Use a tissue and discard immediately, and if possible sneeze or cough into your elbow rather than your hand, to avoid spreading germs. Don’t share food or drinking utensils and regularly clean telephones, TV remotes and keyboards. Try to avoid people who are sick. Look after your lifestyle – avoid alcohol and smoking, eat well and ensure you give yourself time to rest and recover.
