The objectives of the two types of research and their underlying philosophical assumptions are simply different. However, as discussed in the section on âphilosophies guiding researchâ, this does not mean that the two approaches cannot be used in the same study.
Signs and symptoms. Contagious impetigo. This most common form of impetigo, also called nonbullous impetigo, most often begins as a red sore near the nose or mouth which soon breaks, leaking pus or fluid, and forms a honey-colored scab, followed by a red mark which heals without leaving a scar.
Impetigo mainly affects children, often on the face, especially around the nose and mouth, and sometimes on the arms or legs. The two types of impetigo are bullous impetigo and non-bullous impetigo. Bullous impetigo causes large fluid-filled blisters that are painless. Non-bullous impetigo is the more contagious form of the condition causing sores that burst leaving a yellow-brown crust. If the impetigo affects an otherwise healthy area of skin, it is called primary impetigo.
