Abstract
Serologic tests for bluetongue virus (BTV) were done on 19,758 blood serum samples systematically collected at laboratories throughout the USA from Nov. 28, 1977-Feb. 20, 1978. Prevalence of BTV antibody varied from 0-79% of the samples collected in various states, with a national prevalence of 18.2%. The prevalence was generally low in the northern states and high in the southwestern states. The highest prevalence rates were found in Puerto Rico and the Virgin Islands.
