Tick's worm endangers the range to expand The expert claims it may be that the global warming causes
It is suspected that bitten by tick's worm to initiate " have no physique " It may relate to global global warming to infect. The animal researcher He HongXuan of Chinese Academy of Sciences said when being interviewed by media a few days ago: "' a cell of suspected people does not have physique disease ' to repeatly appear in recent years, there can be a lot of conjectures in this, but the greatest possibility comes from global global warming among them. " Some animal of Shanghai monitor and researcher say until trees enter Shanghai some southern pest in recent years too, they may be more difficult in winter to survive in the past, and with global warming, they had already adapted to the environment of Shanghai progressively.
Global warming is hot expand to the temperate zone in spite of illness
Take place in Henan, Shandong and other places transmitting pathogen of disease, although has not confirmed by the intersection of tick and worm finally this time, but not exclusion is " There is no physique " Infection. The animal researcher He HongXuan of Chinese Academy of Sciences said while giving an interview a few days ago: "' a cell of suspected people does not have physique disease ' to repeatly appear in recent years, there can be a lot of conjectures in this, but the greatest possibility comes from global global warming among them. "
He HongXuan points out, global global warming makes the tropical regional range expand, some is originally only limited to insect-pollination infectious disease, parasitic disease of this area appear in temperate zone even frigid zone too. In addition global warming make the intersection of tick and worm multiply person who multiply improve, appear, sting ahead of time too, and " poisonous " Breed in tick's worm and accelerate with development greatly too. A serious one most, climatic change may make the intersection of tick and " poisonous " that worm lead on one's body Algebraical sum shorten each period of time, accelerate the intersection of adaptability and evolution its, have person who invade to animal and people.
The expert still shows, as population increases fast, the human activity area is expanding to wild animal's habitat constantly. Various pollution cause the ecology to worsen, water areas, forest reduce day by day, force the wild animal to move passively too, " poisonous " Bring into the new area.
However, He HongXuan thinks, tick's worm can not counted as the epidemic situation to bite the pathogenic incident this time, "tick activeness of worm issue in 5 to October, until recent it become cool, tick worm propagate ' malicious ' peak, pass by already, the situation should become optimistic gradually.
