鼠的种类与危害 Mice' varieties and their harms
Damage by mice is a serious global problem. Where there are humans,
there are mice; where there are mice, there is damage. Anything
done by a mouse may bring harm to human beings. As far as sanitation
is concerned, mice spread more than 30 kinds of diseases to human,
including plague, epidemic hemorrhagic fever, and leptospirosis.
Statistics shows that ever since there was record, the number of
people died of mouse-spread diseases has been far more than the
total number of those died in wars.
Plague: A wide spreading plague once broke out in China, which
killed 1/4 of its population. At present, plague has been under
control, but the focus of plague in some regions has not yet been
exterminated. In recent years, plagues mainly broke out in China's
neighboring countries, thus potential danger still remains.
Epidemic hemorrhagic fever: it is a disease spread by mice and
can be divided into field mice hemorrhagic fever and house mice
hemorrhagic fever. In recent years, incidence of hemorrhagic fever
in Guangdong province has been on the rise. There were more than
300 cases during 1990-2000, with an annual incidence of 0.05/100,000
and annual fatality rate of around 5%.
Leptospirosis: Leptospirosis has multiple hosts, but is mainly
related with mice. The disease has a wide geographic distribution,
almost covering the whole world. There were more than 3000 cases
during 1990-1998, with an annual incidence of 0.5/100,000 and annual
fatality rate of around 5%.
Mouse belongs to rodentia of mammalian and is a mammal with most
species, featuring large quantity and good adaptability. Mice almost
cover every corner of the world. According to the report from WHO,
there are 1700 species of mice in the whole world, which are classified
into two categories, namely house mouse and field mouse. Three kinds
of house mice that are commonly seen are brown house mice, yellow
breast mice and small house mice. Field mice mainly include yellow
hair mice and bandicota indica.
