The subject of mosquitoes has recently been raised by reason of the occurrence of
indigenous cases of Malaria in this country. The danger of spread of Malaria is only
real in the association of human beings carrying the blood parasite with one of a few
species of mosquito. The mosquito implicated has probably never been absent from
certain districts in England, and many cases of Malaria are now returned from foreign.
It has recently been shown that the species of mosquito necessary to transmission
is present in Tilbury Dock and in the grounds of Denton Hospital. The connection
of these places with malarious centres in tropical countries suggests the desirability of
measures of precaution ; but if, in the future, it is found necessary, a large scheme of
Malaria prevention would naturally include both these places, which are situated on
marshes where mosquitoes abound, and thus hardly form isolated problems in
mosquito control.
SCABIES.
Information was received on the 13th October that the mate of a steamer was
suffering from Scabies. He was treated at the London Hospital, and subsequently
resumed duty. The quarters on the ship occupied by this patient were thoroughly
disinfected, and afterwards repainted ; personal effects were fumigated.
