The present figures show that the virus may be present in the blood as early as 18 hours and as late as 90 hours after the onset. It was not found in the blood 130 hours and 190 hours after the onset.The virus outside the body has been found alive, if kept reasonably cool, in several instances up to 48 hours, and in one instance after 99 hours.It is not possible from this series to draw deductions from the negative cases on this question.Several mosquito experiments in this series have not therefore added to our previous knowledge, but the one satisfactory experiment withCulex fatiganstends to support the view we hold that this species is probably not a vector of the disease. The results previously published by us support the opinion of Bancroft (5) and show clearly that, whether or notC. fatigansmay also play a part in Australia,Stegomyia fasciatais capable of spreading the infection of dengu. |
