Viruses are responsible for 70-80 per cent of sore throats, so the best way to side-step a sore throat is to avoid catching a virus.One way to do this is to practice social distancing. If someone around you is coughing, simply move out of the way. If its you with the cough, then use cough etiquette and cough into your elbow, not your hand, to restrict the spread of germs.Keep your hands clean by washing them frequently, and keep them away from your mouth. If youre one of those people who lick their fingers to turn the page of a book dont do it! For your best defence against viral infections, get a flu shot.
