Write about yellow fever virus - mice & 
jaundice. Trip to Colombia. 
At 2 p.m. had chat with Komp He had with 
him 2 men from Rockefeller Foundation 
(yellow fever work) were going down to West 
Coast Colombia for yellow fever virus, had 
self-contained field labs in one kit box 
including even live mice for all tests and 
collections. On side I hear that yellow fever 
virus serum they have has produced yellow 
(jaundice like) sickness in soldiers treated. 
Apparentl)^ picked up some other virus or 
strain in mice used. Soldiers treated got real 
yellow and some very sick. Looks like a 
modified form of yellow fever.
