INTRODUCTION 



The object of this paper is to analyze the cases of malaria 

 discharged from the Philippine General Hospital, during the 

 fiscal year ending June 30, 1913. This analysis is based not on 

 the results of a special study of malaria but on those of routine 

 work. That this fact greatly affects the data submitted is 

 apparent throughout the paper. I am responsible for the labo- 

 ratory results adduced, while the credit and the responsibility 

 for the clinical data rest with the clinicians. 



FREQUENCY 



A diagnosis of malaria was rendered in 348, or 5.17 per cent, 

 of 6,732 cases discharged during the year; in 324, or 10.6 per 

 cent, of 2,985 medical cases ; in 15, or 2.09 per cent, of 717 obstet- 

 rical cases; and in 9, or 0.3 per cent, of 3,030 surgical cases. 

 It follows that 93.1 per cent, 4.3 per cent, and 2.6 per cent of 

 the 348 infections occurred in medical, obstetrical, and surgical 

 cases, respectively. 



According to the annual report of the Bureau of Health for 

 the fiscal year 1913, a diagnosis of malaria was rendered in 6.1 

 per cent of the admissions to Baguio Hospital, Baguio, Benguet ; 

 in 1.5 per cent to Bilibid Prison Hospital, Manila; in 10.2 per 

 cent to Butuan Hospital, Butuan, Agusan (Mindanao) ; and in 

 51.1 per cent to Iwahig Penal Colony Hospital, Palawan. 



ORGANISM PRESENT 



Of the 296 cases which were positive microscopically, 161, 

 or 54.4 per cent, were infected with tertian; 150, or 50.6 per 

 cent, with sestivo-autumnal ; 3, or 1.0 per cent, with quartan ; and 

 4, or 1.4 per cent, with unidentified parasites. Infection with 

 both tertian and aestivo-autumnal organisms occurred in 22, or 

 7.4 per cent.
