ECONOMIC CONSIDERATIONS 7 



TABLE III 



Showing the expense incurred in the year 191 1 through the 

 existence of malaria in the town of - — , situated in the 



northern Sacramento valley, population about 4000. 



Quinine, 1 100 oz. at 75 cents $822.50 



Quinine, 30,000 gr., 24 gr. at 10 cents 120.00 



Cocoa quinine, 40 pts. at 75 cents 30.00 



Patent medicines, estimated by druggists 1800.00 



Add 20 per cent for sales from drug store not included 



in above 554-5° 



$3327.00 



500 estimated cases of malaria attended by physicians 



(200 cases simultaneously) at $5 2500.00 



5 deaths due to malaria at $1700 8500.00 



500 cases earning capacity reduced for a period of six 



months by 30 per cent, average annual income $800 60,000.00 



Total annual loss due to malaria to the town of 

 $74,327-00 



This does not include depreciation of real estate 

 valuation, which may safely be estimated at 5 cents per 

 $100 assessed valuation. 



The loss inflicted on this town can without exag- 

 geration be placed at #75,000 annually, with every 

 prospect of being increased proportionately unless an 

 active anti-malaria campaign brings a stop to this great 

 municipal leakage. As is shown later in this work, 

 the number of malaria cases in any given protected 

 area can be reduced at least 50 per cent in one year 

 through the agency of an efficient malaria-mosquito 

 campaign, followed by a reduction of 80 per cent in the 

 second and pretty surely by 95 per cent in the third
