TYPHOID FEVER IN DISTRICT OF COLUMBIA. 
known agent or agents causing the dissemination of the disease must 
be peculiarly active in Washington. 
The high death rate from typhoid fever in the District of Columbia 
is partly accounted for by the fact that the disease is more fatal in 
the colored than in the white race. About one-third (90,000) of the 
population are colored. During the period 1895 to 1906 the relative 
average death rates were — 
Per 100,000. 
White 47. 8 
Colored 78. 2 
Total 57.9 
The death rate for 1906, that is, since the filtration of the water, 
was — 
Per 100,000. 
White 35.4 
Colored 83.1 
Total 49.3 
A t}^phoid death rate of about 20 to 25 per 100,000 in the larger 
cities of Massachusetts has been attributed to causes other than 
infected water (prosodemic t5W>hoid). North Adams, with a popu- 
lation of about 25,000, has a "death rate of 39 per 100,000. 
Winnipeg, with artesian water of exceptional purity as its princi- 
pal supply, has a death rate more than double that of Wasliington. 
T}'phoid fever in Winnipeg is also a summer disease. 
Communities have had pronounced epidemics of t 3 zphoid fever in 
which the water is reported to have played no appreciable part. The 
same is true of army encampments. 
So far as typhoid fever is concerned, it seems that Washington may 
be classed vdth the southern cities, where this disease is either unu- 
sually prevalent or unusually vhulent, as indicated by the high 
death rates. 
Death rates yer 100,000 of population of various southern cities from typhoid fever — Average 
for a period of five years.
