3. Directions for Pyrethriun Fumigation. 



Public Health and Marine Hospital Service. 



„ New Orleans, August 18th, loo?. 



General Orders. 



1. Officers in charge of fumigation are directed to use pyrethrum powder, in the 

 proportion of 2 lbs. to 1,000 cubic feet in the preliminary fumigation of houses in 

 which patients are actually sick at the time the fumigation is done. 



2. In using pyrethrum, great care in pasting on the inside of the room all cracks 

 and crevices is necessary, and all save one exit should be pasted before lighting the 

 pyrethrum. 



3. After pyrethrum fumigation, it is necessary to sweep and dust the various 

 rooms fumigated with care, burning at once all sweepings. 



4. The object of this fumigation is to reach, at the earliest possible moment, all 

 mosquitoes which may have bitten the patient, and without irritation to patient and 

 relatives. 



5. Pyrethrum packed in 5 lb. packages can be secured from the Purchasing 

 Agency.

4. Upon the Imperative necessity of Reporting 

 Suspicious Cases. 



This is a very important circular letter which was issued to the 

 Medical Profession of New Orleans urging the importance of report- 

 ing all fevers where the diagnosis is not clear. 



Public Health and Marine Hospital Service. 



New Orleans, August, 1905. 

 Dear Doctor, 



Considering the imperative necessity of instituting at the earliest possible moment 

 prophylactic measures in the case of any person, suffering of a fever which may 

 subsequently be shown to be Yellow Fever, you are urgently requested to report to 

 this office not only any case of fever which you may be sure is Yellow Fever, but also 

 ANY CASE YOU MAY BE UNABLE, even at your first visit, to say is not Yellow 

 Fever. 



We enclose you cards which will facilitate your report of such cases, and will at 

 the same time give us your authorization to inspect the said premises and to do what- 

 ever may be necessary to prevent the extension of the infection in the house or neigh- 

 bourhood. 



We give you our assurance that your rights as the attending physician will be fully 

 respected, and that our inspectors will make no attempt to examine the patient or in 

 any manner endeavor to influence your diagnosis or treatment of the case. 



We shall await your final determination of the case, but hold ourselves ready to 

 serve you with a consultation free of charge to your patient from the enclosed list of 

 gentlemen, who have consented at our request to aid this office in the clearing up of 

 any doubtful diagnosis. 



Feeling sure you will understand the spirit which prompts this communication — 



the desire simply to get the co-operation of the entire profession of this City in the 



checking of the multiplication of the new foci of infection and the early destruction of 



those already existing, 



I am, very truly yours, 



J. H. White.
