There are certain professions and activities that pose a greater risk of developing contact dermatitis. Any profession that requires you to be in close proximity to harmful chemicals, plants, or substances you are allergic to pose a greater risk of developing a rash. Additionally, medical professionals such as doctors, nurses, and caregivers should be extra cautious around patients who have a rash, as they are contagious. On the same note, anyone who works directly with people may be at an increased risk of developing a rash and should consider taking extra caution.
