Locating Anoplides and Aedcs nioscjnitoes in a nciglihor- 

 hood does not necessarily mean that malaria and yellow fever 

 are present. These mosquitoes are not dangcrons lo health 

 unless they have first bitten people sick with malaria or 

 yellow fever. 



Planning a campaign. Yon may carry on a campaign 

 against the mos(piito in a single neighbijrhood or yon may 

 conduct it as a city-wide movement. In either case ofter 

 your services as a class to the board of health. If malaria 

 is present, your map showing location of breeding places 

 of Anopheles might be offered to the board and cooperation 

 secured in wiping out the disease. Arrangements should be 

 made to have a doctor examine, free of charge, any one who 

 has even a slight suspicion that he has malaria. (^)uinine is a 

 cure for this disease, and every malarial [)atient should make 

 use of this remedy (tuider the direction of a physician) and 

 should be screened from mosquitoes to prevent them from 

 becomhio' infected. 



Allow the newspapers to publish the results of your work, 

 together with the accounts of mos(piitoes and the methods 

 of extermhiating them. It is of the utmost importance that 

 every one enter the campaign with enthusiasm, as a few care- 

 less and ignorant people may continue to breed niosiiuiioes 

 by thousands in all sorts of rubbish that can hold a small 

 amotmt of water.
