“…Koplik's spots appearing as discrete, tiny, gray-white papules on a dull-red base on the buccal mucosa, usually appear 1 day before the onset of rash and persist for 2 or 3 days (Suringa et al, 1970). Koplik's spots have been reported in 60%-70% of patients with measles but are probably present in most persons who develop measles (Babbott & Gordon, 1954). Photophobia from iridocyclitis, sore throat, headache, abdominal pain, and generalized mild lymphadenopathy are also common.…”
