Neurological complications of so-called "influenza". A winter study in South-east Wales

Acute neurological disorder followed an upper respiratory infection in 19 patients in south-east Wales during the winter of 1969-70. Spinal and radicular syndromes predominated and included seven cases of transverse myelopathy. Serological tests suggested that the preceding infection was due to influenza A virus in eight cases, to other viruses in six, and were negative in five.
