Will tropical zone be the next focus area of disease? (The picture is offered: Nature)

It is reported through the mode that global disease breaks out in the past 64 years of analysis, the Great Britain and America scientist thinks, it is totally the wrong area that the hygiene of the world monitors personnel and pays close attention at present, this is helpless to prevention of the next epidemic disease and control, the relevant personnel should make the global tactics that disease control. The relevant thesis is published on Nature on February 21.

That led this research is PeterDaszak that world protected the medical alliance. The appearances and diffusion situations of 335 kinds of infectious diseases among 1940- 2004 years that researchers have tracked, include some has caused the tragic kinds of Diseases in the whole world, such as pulmonary tuberculosis of drug resistance, drug resistance malaria and AIDS. Some dangerous factors well known of researcher's quantization - -Such as the influence of population density, draw the conclusion to think, it is mainly several following factors to bring on new disease: The rapid increase of population density, international trade and travel increase and the change of the agricultural activity mode in a large amount. It is these changes that make new diseases since 1940 emerge constantly in a large amount.

Researchers say, though has not made the monitoring focus with concrete disease in the future with data of this research yet, but should invest more control in Africa, Latin America and Asia to monitor personnel, because these areas are going through the similar aforesaid society to change, the risk of the new epidemic disease is highest that they appear. But traditionally, the minimum of control received in these areas. Researchers infer, the greatest risk will come from the low latitudes country at the same time, especially the area which those people contact with poultry's domestic animal freely.

Epidemiologist of British Edinburgh University MarkWoolhouse think supervision and for pin down to it breaks out to be essential future fast reaction in disease. Moreover, it is also very different from known disease of control to monitor new disease.

It shows, it takes more work to confirm the direct control place in future to participate in KateJones of zoological research institute of London of Britain studying. She proposes combining the data of this research with climate model and demographic data, in order to clarify more accurately where disease most possibly breaks out in the future. She says: "It is not clear, we need to pay close attention to the change of the environment that we will anything will happen in the future, in order to make a prediction. "
