The latter workers also reported the isolation of virus during the week prior to onset of illness.…”

Present Trends in Infectious Diseases

“…The following year outbreaks occurred in East Anglia (Garnett et al 1957), the virus being isolated from cerebrospinal fluids, throat washings and faeces of patients. In 1956 there were widespread outbreaks (Tyrell & Snell, 1956 ; Lyle 1956 : Rotem 1957 : Boissard et al 1957 : McLean & Cameron 1957 : Galpine et al 1958 : Jamieson et al 1958: Stones 1958). ECHO virus type 9 was at this time widely prevalent throughout Europe (Nihoul & Querin‐Thiry 1957 : Johnsson 1957) and in Canada (Sultanian & Rhodes 1958).…”
