Like that of other insects, their life is divided into four stages, the egg ; the larva (or caterpillar) ; the pupa (or chrysalis) ; and the imago (or adult, winged insect). The egg is laid on water or near it, and in warm moist weather hatches out in a day or two. The larva is entirely aquatic, and always lives in water. It swims and dives...
Página 6 - Ross considers that something like a quarter of a billion of them must be present to produce fever. The parasites grow larger at the expense of the red blood corpuscles, which at last break down, and then each parasite separates into a number of spherical segments, which escape into the blood stream. Each segment attacks another red corpuscle, to undergo the same development and discharge another...

Avoid sleeping in the houses of natives or near native villages as much as possible.

Página 7 - ... much, though they are a constant source of infection for others, and as they reach the age of puberty the parasites will tend to die out of them by some natural but unknown process. Later on in life they may become infected, and re-infected from time to time, but the natives, in general, seem to be so accustomed to the presence of the parasites that they cease to suffer fever or any other illness in consequence of them. In one sense, malaria is not an infectious disease. Our imaginary careless...
Página 5 - Relapses often seem to be provoked by such things as exposure to the sun, or chill, or fatigue, or other illness, or even indigestion ; but the fundamental cause of them is the persistence of the malaria germs in the blood. The number of parasites in the patient varies from time to time. The more numerous they are, the worse, as a rule, is his fever. One may have large numbers of these parasites in his blood, and yet show no signs of fever. They sometimes continue to live on in a man in comparatively...
Página 36 - Perhaps our first and best defence against malaria lies in the habitual and scrupulous use of mosquito nets at night.
Página 6 - ... blood-stream. All the malaria parasites in the blood of an infected person tend to propagate and produce new segments at the same time, and it is precisely at the moment when these new millions of little creatures are scattered in the blood that the patient's fever begins. Afterwards, when the young microbes occupy fresh blood corpuscles, the fever ceases for a time. But when the new generation is matured and forms segments in its turn, a fresh attack of fever occurs. For a period of from three...
Página 37 - If your house is near a native location, or if you are a traveller and are forced to sleep in a hotel, or in the house of a native, or near a native village, redouble your precautions. It is just in such places that infected mosquitoes most abound. But it is not enough merely to use a mosquito net...
