MALARIA 



TABLE VII 



Comparison based on actual count of absences due to malaria, 

 including cases over five days from September to December in- 

 clusive, during 1909, when no anti-malaria work was in progress, 

 and 1910, when such a crusade was carried on. The average re- 

 duction of absences in per cent is also shown. 



By an examination of the above comparisons it will 

 be seen that the absences in the school due to malaria 

 were reduced by 45 per cent, nearly one half, — and 

 that in only one season's work. This showing in the 

 face of limited funds is very good. The efficiency of 

 this campaign was probably not higher than 50 per 

 cent, therefore under full efficiency a reduction of 

 75 per cent of the cases of malaria could have been 

 expected, with increasing reduction in succeeding years 

 with continuous work. That the reduction of absences 

 is less in October (31 per cent) than in September (38 

 per cent) is due to the fact that there was a change of 

 inspectors in late August and during the interim there 

 was insufficient protection. The result, of course, 

 does not appear, however, until October.
