A new research makes clear, to 2050, china's ceaseless and heated climate may make this country bigger the menace that the area of the area is faced with schistosomiasis to infect.
This research that studies by an international the group undertakes is published in " American intertropical medicine and hygiene " of the magazine Feburary on date, it studied Japanese schistosome (Schistosomajaponicum) distributing with temperature sensitivity, japanese schistosome is the helminth that brings about schistosomiasis in China and southeast Asia country. The sensitive to climate disease that people believes to the air temperature that lifts ceaselessly can bring about a lot of countries on the world is exasperate, have schistosomiasis among them, however accurate the job of respect of distributinging change circumstance returns the space that forecasts schistosomiasis very insufficient, research also contradicts each other as a result. This group of scientists collected schistosome and oncomelania sample -- the agency that oncomelania is this kind of helminth -- the education that has different time below different temperature. Combine historical data, they reach winter is average temperature 0 Celsius are the lowermost temperature that oncomelania can live. They discover schistosome leaves can many breed in warm environment, the lowermost temperature that grow and breeds is 15.4 Celsius. According to the article the first author, xiao Nong says the week of institute of verminosis of center of precaution of Chinese disease control, the historical temperature that they still use Chinese different area and the temperature that forecast developed a model to forecast schistosome to may transmit what area. This group of scientists conclude say, to 2050 transmission meets schistosomiasis be mixed north to expand on the west, the area that raises kilometer of 780 thousand much square -- 8.1% what this occupied countrywide terrestrial area. This group of scientists still are written, they still do not have mature rainfall or rainfall may cause temperature change. But, zhou Xiao farming says to this network reporter: "China and whole world are calefacient closely related the flood that increases ceaselessly, regular meeting promotes schistosome disease transmission. " in an editorial that publishs in this magazine the corresponding period, the United States the CharlesH.King of sanitation of whole world of college of medicine of ministry reservation university and disease research center says Kaisixi, this analysis should be popular to schistosome in the future monitoring and control to offer a focal point. A research that by American cloth the scientist of bright university has is published in what published on March 5 " communal and scientific library · is ignored intertropical disease " magazine, the effect of the symptom that they say to be concerned with schistosomiasis is more serious than World Health Organization is forecasted currently 7, 46 times.
