The International Society of Wheelchairs Professions has issued a leaflet about using your wheelchair during the COVID-19 pandemic. This also contains some great hygiene and contamination precautions.
If you push a manual wheelchair or use other types of assistive technology (AT), there are unique precautions you should take related to hand washing.
COVID-19 can survive on the surfaces of your wheelchair or AT which you come in frequent contact with, such as the hand rims. Any virus that might be on your hands is transferred to your hand rims as you push your wheelchair.
