This type of rash is common in several diseases and medical conditions, including scarlet fever, measles, Ebola virus disease, rubella, HIV, secondary syphilis (Congenital syphilis, which is asymptomatic, the newborn may present this type of rash), erythrovirus (parvovirus B19), chikungunya (alphavirus), zika, smallpox (which has been eradicated), varicella (when vaccinated persons exhibit symptoms from the modified form), heat rash, and sometimes in Dengue fever.In the case of GVHD, the maculopapular lesions may progress to a condition similar to toxic epidermal necrolysis.[2] In addition, this is the type of rash that some patients presenting with Ebola virus hemorrhagic (EBO-Z) fever will reveal but can be hard to see on dark skin people.This stinging, pruritic, maculopapular rash affects swimmers in some Atlantic locales (e.g., Florida, Caribbean, Long Island).It is caused by hypersensitivity to stings from the larvae of the sea anemone (e.g., Edwardsiella lineate) or the thimble jellyfish (Linuche unguiculata).
