What Experiments Proved.
The Reed Memoir continues:
Besides the experimental cases caused
by mosquito bites, four non-immunes
were infected by injecting blood drawn
patients in the first two days Of the
disease. thus demonstrating the presence
of an Infectious agent In the blood at
this early period OF the attack.
