There are still no vaccines to prevent malaria. The main way for communities to control the disease is by controlling mosquitoes.
现在仍没有疫苗可预防疟疾。控制这一疾病的主要途径是灭蚊。
________________________________________________________________
The fight against malaria has two main targets: the parasite itself and the mosquito that carries the parasite. Insecticides target the mosquito. But over time the insects develop resistance to the chemicals. This has been happening with current mosquito killers, including chemicals known as pyrethroids.
抗击疟疾有两个主要目标：杀灭寄生虫和携带寄生虫的蚊子。杀虫剂是用来对付蚊子的，但时间久了，蚊子就会对这种化学药品产生抵抗力。现在的杀蚊剂，包括除虫菊酯类化学品就遇到过这种情况。


注释：
malaria：疟疾，瘴气
spray：喷射，喷洒
