MOSQUITO ERADICATION 



Each physician was left a number of postcards upon which to 

 report monthly the number of calls he had made upon persons 

 suffering from malaria within the area of operations. These were 

 entered, as soon as received each month, in the 1920 column of the 

 No. 1 form sent in by that physician. In this way the efficacy 

 of the control measures each month was visible at a glance. 



To get the total for the town, each physician's figures by 

 months for the years 1918 and 1919, and also for 1920 as they were 

 received, were added together on another blank similar to Form 

 No. 1, thus giving at a glance the situation for the town as a 

 whole. 



Where other mosquito-borne diseases are a factor, statistics 

 regarding them should be collected also. 



In cases where it is impracticable to obtain the desired infor- 

 mation from the physicians of the community, a house-to-house 

 malaria census may be taken. This method probably will not 

 be so accurate as the method of obtaining figures from the 

 physicians for obvious reasons, but will serve as a basis for 

 comparison. 



The following malaria census card is suggested as suitable for 

 use in ordinary cases: 



FORM NO. 2
