“最重要的是，這種方式比現(xiàn)有的快速診斷測試要快得多，測試需要二十分鐘，而且還需要一位受過全面培訓(xùn)的專業(yè)人士來完成。然而，如果我們帶著醫(yī)療檢測犬到社區(qū)里轉(zhuǎn)一圈，就可以在很短的時間內(nèi)查完整個社區(qū)的情況?！?/p>

The researchers will need to improve the dogs’ accuracy, test them on people rather than socks and investigate whether the animals can sniff out different strains of malaria.
這些研究人員需要提高狗檢測的準(zhǔn)確率，讓它們在人身上，而不是在襪子上測試，并研究這種動物能否聞出不同種類的瘧疾。
