HYGIENE 541 



Dengue. 



Its prevalence is greatest in the hot season. It affects maritime 

 towns and seldom spreads inland. Low-lying, filthy and overcrowded 

 quarters are the first attacked. 



SOME GENERAL RULES FOR THE MAINTENANCE OF HEALTH 



IN THE TROPICS. 



All defective teeth should be corrected by a qualified dentist before 

 the traveller leaves Europe. 



It is preferable to abstain absolutely from alcohol. 



If alcohol is taken it should be in great moderation after sunset. 



Take a dail_v tepid bath, preferably at sundown, before food. 



Cold baths are tmsafe for all who have any bowel weaknesses. 



Judicious exercise is of great value, taken in the earl}- morning or 

 the late afternoon, such as golf, cricket, croquet, polo and tennis. 



Chills afterwards should be avoided. 



The great temptation to lead a sedentary life must be overcome. 



A muslin mosquito net, twenty strands to the inch, tucked under 

 the mattress one hour before sundown, and kept in good repair, is 

 essential. 



High boots, leggings, or puttees are of great value for all travel- 

 ling through bush for the protection of the legs from snake and insect 

 bites. 



Light khaki clothes with spine pads for the bush and white drill 

 for the stations and evenings are best. Wool is irritable to the skin. 



A mixture of wool-silk is comfortable, e.g., Anglo-Indian gauze. 



Silk next to the skin may be necessary for those whose skins are 

 irritable as a result of perspiration, &c. 



All personal servants sliould take a daily bath and be free from 

 infectious disease. 



All water should be boiled and filtered. It is a good plan to drink 

 weak tea or coffee instead of water, as this ensures the water having 

 been boiled. If a filter is not obtainable a little alum added to the 

 water is useful. Boil it after standing. 



Keep all food supplies awav from flies in a gauze receptacle. 



All fresh milk must be boiled. 



Take Cjuinine; hvdrochloride is better than the sulphate, 5 grains 

 daily, except Sundays, when take 2 grains of calomel, followed by half 

 an ounce of Epsom salts. 



Jaeger sleeping sacks are useful for those sleeping out. 



Always dress according to the temperature, and not according to 

 appearances and the " climate." 



After perspiring change clothes frequently.
