The whole world of malaria for 1900 have illness coming on in the area ' Have) With the morbidity area in recent years ' China) ,And district that morbidity increases only take very little area in the whole world ' Leave) .

It is reported that perhaps can leave out one in the list on potential negative effect of global warming. New research shows, even if the reading of the thermometer still rises, therefore malaria that causes gets rich quick on the influence led to the fact is limited. Researcher break out malaria at the beginning of the 20th century situation compare with situation of recent years, find even global global warming, but the development of the economic and medical level, can still help the mankind to overcome malaria very effectively, it means to on the prediction of development trends of tropical disease such as malaria,etc., climatic change is not the only decisive factor.

Malaria is one kind the mosquito bites parasitic disease transmitted, nearly 1 million people die of this disease every year in the whole world, and there are 2,400 million people - -Account for global total 1/3 of population - - face threat of malaria nearly. The most fatal malaria is caused by plasmodium, but the most fatal biography disease media is the ridge Bia's malarial mosquito. Because the warm climate is favorable to the spread of malaria, some people believe, the global warming may increase morbidity and intensity of malaria, and then cause more infection and die.

But some malaria experts have been suspecting the connection between these two. Several years ago, it was called malaria map plan (MAP) that they initiated one Research. Researchers aim at drawing for one now at first global malaria is distributed the map. In recent research, through putting a result of study that the Soviet Union released in the sixties of last century in order, MAP has obtained malaria from the year 1900 till now and propagated the data. Researchers propagate the situation of a piece of malaria since century to compare with subsequently. The result reveals, though the temperature increased 0.6 equally in the 20th century, the morbidity area of malaria dwindled dramatically. Compare with revealing, the large-scale malaria epidemic situation nearly disappears in Europe and North America, obviously shrink in the spread range of the malaria in the area in the equator of Africa too. This benefits from insecticide and mosquito net, certainly have use against malaria medicine. The epidemiologist PeterGething of British Oxford University that presides over this research says, this is why " we saw last century though the temperature was rising, but the reason that the morbidity of malaria is dropping " . Researchers have reported this research results on recent Nature published.

Gething say according to study analysis of group, these disease control means offset temperature, rise in influence that future lead to the fact enough totally. Researchers find, it is 100 times of influence that the temperature change has illness coming on and forms to malaria to use the result that these countermeasures produce in the whole world. He explains: "We have not totally expounded the reason why the malaria morbidity drops yet, but our research has transmitted a clear information for the future. " He says, the hygiene officers of various countries " so long as can overcome the influence that the temperature rises and brings easily when using these effective control means that we mention, but the prerequisite is that these measures must reach those crowds needing them most in the hand " .

Gething shows, this challenge is encouraging the international community through reducing death and spread of malaria as to the simple means. He emphasizes, " it is very difficult to impute to climatic change " in any difficulty that we meet .

The medical entomologist PaulReiter of France Paris Pasteur research institute says: "We had a thesis written with the practical data by expert of this field at last. " Reiter emphasizes, some prediction carried on in climatic change to causing malaria to get rich quick is " irresponsible " ,And " On the basis of the intuition and to the abuse of the preliminary model " .

The epidemiologist MarkWoolhouse of British Edinburgh University claims this research is to some diseases transmitting through media to relevant climatic change - -Such as malaria - -Important contribution that the discussion on influence that caused has been made. He says, these data clearly show, compared with rise of the mercury, the effectiveness of the public health means of controlling malaria is the key to the question. (beautiful and fragrant flowers)
