Because they could have a contagious disease. this reason is why paramedics like me wear gloves when rendering first aid.And the care giver doesn't want to get that therefor they should use proper safety precautions.
Because providing first aid is an half to half situation were if the person who provides the assistance do properly of if it is successful then is Fine/Good but when thats person go wrong on proving first aid, it might damage or hurt the person who you treating so maybe it is going to ruin your name and reputation
