A coxsackievirus type A24 epidemic of acute conjunctivitis

Abstract

The 1975 epidemic of acute conjunctivitis was caused by the return of S.E.C. 1970 virus (CA24). The clinical manifestations of cases seen in the recent epidemic were similar to those seen during the 1970 epidemic caused by S.E.C. 1970 virus (CA24) and the 1971 epidemic caused by S.E.C. 1971 virus (entero-virus type 70). In our opinion, both the S.E.C. 1970 VIRUS (CA24) and S.E.C. 1971 virus (enterovirus type 70) are equally important causes of epidemics of acute conjunctivitis more commonly known as the "Acute Haemorrhagic Conjunctivitis". Although these two enteroviruses affect mainly the eye, apart from conjunctival secretions, they could be transmitted in respiratory droplets and faeces. The authors would prefer to retain the term "Picornavirus Epidemic Conjunctivitis" to denote infection by S.E.C. 1970 virus (CA24) and S.E.C. 1971 virus (enterovirus type 70).
