Inspired by the Christmas song “Jingle Bells”, this greetings card lists two of the main symptoms of COVID-19 – a high temperature and a loss of smell. NHS England adds loss of taste and a new, persistent cough, stating that many people will have at least one symptom. NHS England recommends for anyone with symptoms and those in their household to only leave home for a test.
