Cross-Infection in scarlet-Fever bed isolation wards

Extract
1. The incidence of cross-infection with Str. pyogenes during a period of four months was compared in two blocks occupied by scarlet-fever patients. One block was nursed by the bed isolation method and the other by the ordinary method in current use for multiple-bed wards. 2. The rules for the bed isolation blook are given. 3. The incidence of cross-infection with Str. pyogenes among patients in the bed isolation block was 20·3%, that among patients in the ordinary block 22·6%. 4. We concluded that the bed isolation nursing technique practised was not effective in reducing cross-infection with Str. pyogenes among scarlet-fever patients. 5. A further test of bed isolation nursing was made for six months, using the extra precaution of vacuum-cleaning the floors. We found that crossinfection was still occurring, but the incidence could not be estimated since the Str. pyogenes strains isolated had to be destroyed at the outbreak of war. At this time the serological typing had not been completed. 6. The importance of dust-borne and droplet-borne infection in addition to that of contact infection is discussed. The type of investigation required to decide whether cross-infection in multiple-bed scarlet-fever wards can be eliminated by the methods at our present disposal is outlined.
