Early 1946 in
Regency Park, a housing development in the Kew Gardens
section of the borough of Queens, New York City.
Cases were first seen by physicians in the neighbourhood at the
beginning of the year.
About a week after the appearance of the initial lesion,
there was an acute onset of fever, chills, sweating, backache and headache,
followed in 2 to 4 days by a generalized maculopapular and papulo-vesicular
