Blood Groups and Blood Transfusion

Abstract

CLINICAL MEMORANDA THE BitTisH view of the close contact in messes and the congestion inevitable on a warship in time of war. Here it may be recalled that previous history of morbilli in childhood is no guarantee of protection against rubella. (2) The incubation period of the first case, as defined above, cannot have exceeded nine days-a shorter period than that usually recognized. (3) It would appear that the period of isolation usually enforced ashore for rubella, before regarding a case as non-infectious, may be safely shortened by several days, with a corresponding saving of working time. (4) On the facts available there is insufficient evidence to show that the occurrence of these two virus diseases together was any more than a seasonal coincidence. Thanks are due to the Principal Medical Officer for permission to record these notes.
