Remember to clean your hands frequently. Exhibitors will have alcohol gel available on their stands and there will be dispensers available around the exhibition hall. Ensure you clean your hands before and after interacting with an exhibitor's stand, especially if you wish to pick up something to look at or have taken an item from the stand e.g. a complimentary product.
In situations where you will need to handle a product, such as trial a wheelchair, exhibitors will also have gloves available as an additional layer of protection.
If you are unable to use hand sanitiser gel, ensure you are visiting the toilets frequently to thoroughly wash your hands with soap and water.
