Ribavirin
Postexposure prophylaxis for measles
In healthy individuals, the measlesmumps-rubella (MMR) vaccine should be given to boost immunity if it can be administered within 72 hours of measles exposure

pruritic pink to red macules and papules that begin on the face, quickly progressing to involve neck, trunk, and extremities
Primary rubella infection
congenital infection include growth retardation, interstitial pneumonitis, radiolucent bone disease, hepatosplenomegaly, thrombocytopenia, and dermal erythropoiesis (“blueberry muffin lesions”)
CONGENITAL RUBELLA SYNDROME
primary manifestation of B19 viral infection in adults
Acute arthropathy
Treatment for uncomplicated infectious mononucleosis
symptomatic
useful in treating the fever or throat discomfort
acyclovir is not routinely used in the management of EBV infection
abrupt onset of symmetrically distributed, monomorphous papules or papulovesicles on the face, extensor surface of extremities, and buttocks
preceded by malaise, pharyngitis, low-grade fever, and lymphadenopathy (typically cervical, axillary, or inguinal)
GCS
development of “rose”-colored macules and papules measuring 2 to 5 mm and surrounded by a white halo
EXANTHEM SUBITUM
HHV-6
development of a vesicular eruption on the palms and soles
football-shaped” erosions surrounded by an erythematous halo
HFMD
