﻿IX, B, 2 Sanitary Survey in Mindoro 137 



9. RECOMMENDATIONS 



Successfully to cope with the sanitary problem connected with 

 the Mindoro properties demands a definite organization of a 

 sanitary department with its personnel, equipment, and sup- 

 plies; the delegation of a definite authority; and sufficient ap- 

 propriation to carry on the work. The head of this department, 

 whether he be an employee of the company or of the Government 

 or of both, unquestionably should have the authority and perform 

 the duties of a district health officer, not only for the Mindoro 

 properties but for all outlying barrios. This department should 

 direct its efforts along the following lines : 



1. The prevention of reinfection by the importation of malaria-free laborers 



and by restricting the intercourse between the inhabitants of the 

 protected zone and infected persons in near-by territory. 



2. Efficient hospitalization for sick people. 



3. Satisfactory free dispensary service for those who are not ill enough 



to require hospital care. 



4. A visiting service for the location of carriers and other infected persons. 



5. The systematic treatment of all persons (compulsory if necessary) harbor- 



ing the malarial parasite. 



6. Constant application of approved methods for the reduction of anopheline 



mosquitoes. 



7. A sanitary corps whose duties should be the cleaning up of new camps 



before such camps are occupied by laborers. 



8. Supervision of the housing and feeding of employees, their families, and 



all other inhabitants of the zone. 



9. Carefully planned and systematic reports from all divisions of this 



department. 



As is well known, the propagation of malaria depends upon the 

 integrity of a three-link chain, and the breaking of any link 

 or the reduction in the strength of all three links embodies 

 the whole principle in combating this infection. The three links 

 are: 



1. The infected person. 



2. The proper variety of anopheline mosquitoes. 



3. The nonimmune person. 



The campaign against this infection, therefore, must be along 

 three principal lines and along all of them at the same time : 



1. The suppression, as far as possible, of the propagation of anopheline 



mosquitoes. 



2. The protection, as far as possible, of nonimmune persons from mosquito 



bites, particularly at night. 



3. Most important of all, the prevention of the introduction of new cases 



from without and the thorough treatment of all infected cases whether 

 new or recurrent, within the inhabited zone, together with the protection
