BACKGROUND: Measles is usually considered to be a childhood disease. R
ecent epidemiology data suggest that it is in progress amongst the adu
lt population despite generalized vaccination. CASE REPORT: Within a 3
-week period, two brothers, aged 19 and 21 years, developed fever and
interstitial pneumonia. Characteristic maculopapulous eruptions occure
d later leading to measles diagnosis. DISCUSSION: Although the clinica
l course is usually benign, measles can cause severe complications, pa
rticularly respiratory involvement that occurs in 3 to 10% of adult me
asles cases. The virus can affect the respiratory epithelium directly
leading to bronchopneumonia which develops prior to the cutaneous erup
tion; all manifestations then regress together as in our two cases. La
ter complications due to bacterial superinfections can occur. Measles
should be considered in adults with fever and interstitial pneumonia.
