Johnstone, J. A., Ross, C. A. C., and Dunn, M. (1972). Archives of Disease in Childhood, 47, 647. Meningitis and encephalitis associated with mumps infection: a 10-year survey. During the 10-year period 1960-69, 137 patients in Ruchill Hospital were diagnosed by clinical and laboratory findings as mumps meningitis. Parotitis was detected in only 51 (37%). There was a male preponderance, 97: 40. 960% of the males were under 10 years old compared with 78% of the females. The peak incidence of patients with meningitis alone was in June-July, parotitis with meningitis was from November to January. All 137 meningitis patients made a good recovery. Of the 2 definite cases of mumps encephalitis 1 showed severe psychomotor sequelae. More of the total 139 patients showed rising titres to mumps 'V' envelope antigen than to mumps 'S' nucleoprotein antigen.
