3 Protocol Interventions

Specific interventions used were three infection control protocols. The three protocol interventions was designed and composed from several existing protocols and were ordered according to the extensiveness of the interventions. The way that these protocols were implemented was by visiting the participation nursing homes and assigning them one of the three protocols by the municipal public health services. As a result, the study showed that infection control measures are to be most effective when implemented before or at the moment that the first peak of symptomatic subjects is observed. Additionally it was found that the implementation of infection control measures reduced attack rates, but had little effect on the length of the out break
