When is it necessary to wash your hands before and after giving first aid?

Washing your hands before and after giving first aid is essential to avoid infection from body fluids. This practice helps ensure that any potential pathogens or contaminants are not transmitted from the first aider to the victim or vice versa. This is particularly important when dealing with wounds or situations where body fluids may be involved, as these can be sources of infection for both the injured person and the person providing aid. Ensuring proper hand hygiene minimizes the risk of spreading infections and contributes to overall safety during the first aid process.
