Malaria,in second place,sees fewer victims,but greater difficulty of control. With climate,including global warming,as complications

This is an article on malarial risks and prevention. Malaria is the deadliest tropical parasitic disease and one of the leading causes of death. The risk for this disease has been linked with changes in land use related to road building, mining, logging, and agricultural and irrigation projects. Global climatic change, disintegration of health services, armed conflicts, and mass movements of refugees also contribute to the increasing risk for malaria. Disease prevention includes a variety of measures that may protect against infection. They may be directed against the mosquito vector or against the development of disease in infected individuals. The WHO stresses the curability of malaria in spite of the occurrence of drug resistance. If the antimalarial drugs are used properly and targeted to those at risk, malarial disease and death can be reduced. Vaccines are also in development; an effective one could be available within the next 7-15 years.
