assistants are waging here and else

Connor got from the Rockefeller
Board in 1918. Success already
scored in completely eradicating the
disease in Ecuador and other sue
cesses in Mexican cities on the Gulf
Of Mexico leads DR.. Connor TO make
the prediction so full of cheer for
millions in the hot portions Of
South, Central and southern North
America.
Dr. Connor's campaign against the
disease has been pressed at such
cities as Guayaquil and Merida,
whore it has been endemic for years
and rom which IL has spread to
other sections.
with Guayaquil cleaned up, Ne
rida virtually cleaned up and rapid
reductions in cases being scored in
Puerta Mexico, Vera Cruz and other
Gulf ports. just one important yell
low focus in Brazil remains 20 be
disposed Of before the world will be
free Of the disease.
Eradication Of yellow fever" says
Dr. Connor. was a self-imposed
task undertaken by the Rockefeller
Foundation international Health
Board.
Medical authorities agree 1t is a
disease Of American origin.
yellow fever was probably intro
duced into Ecuador and Panama in
1910; and there are excellent rea-
sons 20 believe that is was present
in the former country until May
1919. when I was able TO announce
that IL was free Of the disease.
THE disease is caused by a germ
discovered by DR.. Noguchi. Of the
Rockefeller Foundation, in Guaya-
Gull. during our fight to eradicate the
disease The germ is carried from
one person TO another by the female
ategomyia mosquito and IN no Other
manner.
This insect breeds in receptacle'
used for storing fresh water in oi
near human habitations and thus
has earned the name Of house mos
quito.
The mosquito receives the vel
low fever germ into its body while
sucking the blood of an infecte,
person during the first three day
81 the illness.
Twelve DAYS later the mosquito
returns to such blood again.
IF Il happens the person thel
bitten has never had the disease. tn
germs find their way into his bloo'
stream, multiply, and throw on
poison which produces the disease.
con the other hand, II the persoi
bitten by the infected mosquito ha
previously had yellow fever. he SUI
fers no harm.
