There must also be contact-tracing measures in place and personal hygiene measures should be followed. This includes washing hands with soap and water before and after each game, or using hand sanitiser if this is not possible, and regular sanitation of shared equipment such as balls, sticks etc. People who are sick with colds or flu should not take part in training or games. They should contact their GP or Healthline and be tested for COVID-19.
