Cystic fibrosis in black population.

In this study, we will report on a high number of black 
cystic fibrosis patients in Brooklyn, New York, with a description of 
these patients and the population of the area in which they 
reside. A total of 70 cases of cystic fibrosis were followed 
at the Long Island College Hospital. Ten, 14.2 per cent, of 
the 70 cases of cystic fibrosis are black. These are equally 
divided into 5 females and 5 males.
