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

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.1the following are the advantages of the new
