TRANSMISSION OF YELLOW FEVER BY MOSQUITOES. 673 



ward shall be made mosquito-proof by wire iiettinfi over doors and windows, a ceiling 

 of wire netting at a height of 7 feet above the floor, and mos(]uito bars over the beds. 

 There should be no place in it where mosquitoes can seek refuge, not readily accessi- 

 ble to the nurse. Both wards can be in the same building, provided they are sepa- 

 rated by a mosquito-tight partition. 



5. AD persons coming from an infected locality to a post shall he kept under care- 

 ful o))servation until the completion of five days from the time of possible infection, 

 either in a sjiecial detention camp or in their own quarters; in either case their tem- 

 perature should be taken twice a day during this period of observation, so that tliose 

 who develop yellow fever may be placed under treatment at the very inception of 

 the disease. 



6. Malarial fever, like yellow fever, is communicated by mosquito bites, and there- 

 fore is just as much of an infectious disease and requires the same measures ol pro- 

 tection against mosquitoes. On the assumption that mosquitoes remain in the 

 vicinity of their breeding places, or never travel far, the prevalence of malarial fever 

 at a post would indicate want of proper care and diligence on the i)art of the surgeon 

 and commanding officer in complying with General Orders, No. 6, Departnu-nt of 

 Cuba, 1900. 



7. Surgeons are again reminded of the absolute necessity, in all fever cases, to keep, 

 from the very beginning, a complete chart of pulse and temperature, since such a 

 chart is their best guide to a correct diagnosis and the proper treatment. 



By command of Major-General Wood:
