common and contagious skin disease that causes itching, scaling, flaking, and sometimes blistering of the affected areas. |
|
Crust |
An outer layer from the drying of exudate, secretion, or hemorrhage. |

caused by a member of the pox virus family, is a cutaneous eruption consisting of one or more, 1 to 3 mm. diameter, flesh colored papules with a central umbilication. |
|
Measles- maculopapular rash |
caused by a morbillivirus, a member of the paramyxoviridae. The prodromal symptoms of measles such as fever, malaise, and conjunctivitis with photophobia, typically begin after an incubation period of ten days. |
|
Chicken Pox- vesicles |
Varicella is caused by Herpesvirus varicellae, also known as the Varicella zoster virus. Typical varicella lesions are clear, tense vesicles, surrounded by an erythematous halo, that erupt over the skin surface, after a 9 to 21 day incubation, and a day or two of fever and malaise. They change from clear to turbid pustules in 2 to 3 days. Lesions then break, producing crusts. |
|
