i 5 6 MALARIA 



"The National Conservation Commission reported 

 to President Roosevelt that 80 per cent of malaria could 

 be prevented. Applying this same percentage to this 

 total loss, there results a net preventable loss of #2,256,- 

 000 annually. The significance of this loss can best 

 be brought out by some comparative statistics. The 

 United States mortality reports show that in 1909 

 California had one eleventh of all the deaths from 

 malaria in the registration area, 1 which includes eight- 

 een states, and ranked second in number of deaths 

 for a single state. Indiana was first with 125 deaths, 

 New York third (95 deaths), Ohio fourth (75 deaths), 

 Pennsylvania fifth (50 deaths). In proportion to 

 population California outranks all other states in this 

 area. Within the State 66 per cent of the deaths 

 occurred in ten counties extending in an almost un- 

 broken chain along the base of the Sierra Nevada 

 Mountains. The total population for these counties 

 (1910 census) is 326,896. Malaria, therefore, causes 

 five times as many deaths per 100,000 of population 

 as the average for the United States registration area. 

 In these ten counties 2 the 1909 death rate was one 



ment of Agriculture, estimates the annual cost to the United States for 

 malaria to be $100,000,000. In proportion to population California should 

 represent one thirty-eighth of this, or $2,630,000 per year loss. 



1 Registration area is area making full reports of all deaths to Census 

 Bureau. It includes California, Colorado, Connecticut, Indiana, Maine, 

 Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New 

 York, Ohio, Pennsylvania, Rhode Island, South Dakota, Vermont, Wash- 

 ington, and Wisconsin.
