Proceedings of Seventh Annual Meeting 23 



In the meantime an Anopheles survey of the whole of Switzer- 

 land was begun under government auspices, since malaria had de- 

 veloped on account of the presence of malaria carriers among the in- 

 terned prisoners of war. 



England did not suffer at first, but of course malaria developed 

 among the British troops in Macedonia and on the other Balkan 

 fronts and eventually was carried home. For example in 191 7 at 

 Sandwich, England, there were 69 indigenous cases of malaria as 

 the result of the infection of native Amopheles by returned troops. 

 Most extensive operations were undertaken in the prevention of 

 larval development at this place. Operations were begun on no- 

 toriously infested waters, and more than twenty miles of dikes were 

 drained and kept free from weeds. In 1918 only six cases de- 

 veloped, from what was termed "a local defect in detail." Cases 

 were reported both from military bases and naval bases, and the 

 well known ''Reports to the Local Government Board on Public 

 Health and Medical Subjects" have contained a series of reports and 

 papers on malaria contracted in England. Good anti-mosquito work, 

 devoted to the breeding places, is being done and will doubtless be 

 carried through. A small part of the sum which has been spent in 

 New Jersey in the abolition of mosquito-breeding places will go far 

 toward relieving England from the malaria danger. 



Of course, extensive operations were carried on in the Balkans. 

 In 1916, malaria having increased in Macedonia with the Army of the 

 Orient, army operations resulted in the oiling of all standing water. 

 More than 160,000 mosquito nets were issued to the men. Malaria 

 was practically the only disease from which the Balkan armies 

 suffered from July to October, 191 6. It was an extremely virulent 

 type of the disease and difficult of control by the usual quinine treat- 

 ment. 



In Spain malaria did not increase during the war, it was stated, 

 because of the constant propaganda disseminated by the sanitary 

 authorities ; and this result is all the more marked since quinine was 

 lacking very largely from the outbreak of hostilities and food was 

 scarce. 



In Roumania, anti-malaria operations were carried on by the gov- 

 ernment down to 19 1 6, and after the occupation of that country by 

 Germany they were continued by the German authorities. In 191 7 

 anti-malarial-mosquito work was planned for lower Albania.
