阅读理解 The World Health Organization is using a new combination of drugs to treat African trypanosomiasisdisease,also known as sleeping sickness. The drugs will be given out in Uganda and the Democratic
Republic of the Congo.
Officials says the new treatment has fewer side effects. It is also more effective and less costly than
the drugs traditionally used. In addition,the new treatment reduces the number of injections needed. And
it shortens the amount of time patients must spend in hospital.
Sleeping sickness threatens millions of people in 36 countries in Africa. Most live in poor rural areas.
The disease is caused by the trypanosoma parasite(寄生物). It is spread to humans through the bite of
infected tsetse flies. Common signs of sleeping sickness include fever,headaches,extreme tiredness and
pain in the muscles and joints. Early identification of the disease may be difficult because many infected
people do not show any immediate symptoms. Over time,the parasites invade the central nervous system. The disease causes sleep disorders,mental confusion,personality changes and speech problems. If left
untreated,sleeping sickness kills.
It's estimated that about 60,000 people are currently infected with the disease. It develops in two
different forms. Trypanosoma gambiense is responsible for 90% of the reported cases of sleeping
sickness. People infected with this form may develop the disease over many years without any major
symptoms. Until now the drug melarsoprol is used to treat patients in the advanced stage of sleeping
sickness. But the drug requires many painful injections several times a day for several weeks. It also
causes bad side effects,some of which can be deadly.
In Uganda,a new study has confirmed earlier research linking the spread of sleeping sickness to
infected farm animals. The writers of the study have called for stronger rules requiring cattle to be treated
before being sold at market.
