RT Journal A1 STENN F, STENN H T1 REcidivating measles JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1939 FD February 1 VO 57 IS 2 SP 368 OP 370 DO 10.1001/archpedi.1939.01990020126013 UL http://dx.doi.org/10.1001/archpedi.1939.01990020126013 AB Recidivating measles is rare. Loos,1 Panum,2 Salzmann3 and Widowitz4 failed to observe it in over 9,000 cases of measles, and Kleinschmidt,5 Friedjung,6 Stolte,7 Lichtenstein8 and others with vast experience among patients with measles observed not a single case. However, up to 1894 Maiselis9 collected from the literature 103 instances of a second and 3 of a third attack. Of Ryhiner's10 series of 2,000 cases there were repeated attacks in 2. According to Salzmann's review, of 4,206 cases of measles reported by various authors 200 were instances of repeated attack. Le Bourdellès11 called attention to 40 per cent recidivation of measles in an army camp. But many of these reports are inaccurate and thus unreliable. Undoubted instances of repeated attacks of measles have been described by Wolff,12 Glanzmann,13 Golberger,14 Erdheim,15 de Rudder,16 Ryhiner and others.
