An investigation into the distribution of malaria in the Koritza 

 region of lower Albania, undertaken between June and September 1917, 

 showed that this locahty is highly malarial, the centre of infection 

 lying around Lake Mahk. On the plains, the percentage of infection 

 falls in proportion to the distance from the lake, becoming very small 

 in the mountain villages. Lakes Ochrida and Presba being deep, 

 and without marshy surroundings, have httle influence on the 

 malarial index of their basins, the variations met with in the river-side 

 villages being dependent on local conditions created by the water- 

 courses themselves. 



A consideration of the Anophehne faima, taken in conjunction 

 with the plasmodial form met with, leads to the conclusion that the 

 type of malaria existing in the Koritza region is that characteristic 

 of a temperate climate.

The whole region of the Macedonian frontier is only slightly malarial, 

 with the exception of the valley of the Presba lakes. Here the endemic 

 index is relatively high, some severe cases of enlarged spleen occur, 

 adult Anophelines and cases of primary malaria are numerous, and a 

 large expanse of water and considerable marshes exist ; in the other 

 valleys Anophehnes are few or absent, cases of primary malaria are 

 scarce and the water area is at a minimum. 



Cases where the low endemic index is associated with the existence 

 of numerous breeding places and the presence of Anopheline larvae, 

 are doubtless explained by climatic conditions, chiefly cold at night, 

 which is unfavourable to the development both of mosquitos and of 

 the malaria parasite.

This paper gives technical and practical advice on the subject of 

 the control of mosquito larvae. The beds of rivers, if sandy, must 

 be kept free from bushes likely to form islets, and from stakes and 

 bridges that cause patches of stagnant water in the midst of the 

 current. The banks, especially after rain, must be kept free from 

 pools, either by filhng-in or by drainage into the river at a point 

 lower down, by means of open ditches. Trees bordering rivers should 

 be cut down, and useless vegetation burned. A measure, based on the 

 fact that the mosquito is a nocturnal insect, can be adopted when the 

 river banks are almost vertical and easilv accessible. Holes about
