PARATYPHOID B.
During the year a child was notified as suffering from paratyphoid
B. Three further cases were diagnosed among children
attending the same school. In collaboration with the Medical
Officers of Health of two neighbouring authorities a full investigation
was made. Faecal specimens were obtained from the
staff and all children attending the school which, in this district
alone, necessitated over a thousand visits. Six symptomless excreters
were discovered and isolated until free from infection.
Extensive investigations finally shewed that the probable
cause of this outbreak was a baked chocolate sponge with jam
and cream filling.
DYSENTERY.
Only one case of sonne dysentery occurred during the year.
