Malaria : A disease caused by a plasmodium parasite, transmitted by the bite of infected mosquitoes

The spread?

Malariais a serious, sometimes fatal disease that's spread through the bite of an infected mosquito.With certain malaria species, dormant forms can be produced which may cause relapses of malaria months to years later. Malaria may also be transmitted by transfusion of blood from infected people or by the use of contaminated needles or syringes.

Where did the disease originate

This originated in Africa about ten thousands years ago!There are several different types of malaria in Africa.Many of its closely related species occur in south-east Asia, which leads some researchers to suggest this is where it emerged, passing into Africa as humans and their livestock moved across Asia towards the Middle East and North Africa, or possibly via migration through Madagascar.

Outbreak in government?

1957 and 2014, in the United States, 63 outbreaks of locally transmitted mosquito-borne malaria have occurred; in such outbreaks, local mosquitoes become infected by biting persons carrying malaria parasites.Despite dramatic declines in malaria cases and deaths since 2000, more than half a million lives are still lost to this preventable disease each year.

Outbreak in economy?

In recent years, however, there has been a sharp rise in the number of malaria cases in South Africa, and indeed throughout Southern Africa. This rise is due to a number of factors, such as high rainfall in recent years, increased migration and a reduction in the use of DDT in vector control. The rise in malaria cases imposes heavy costs on the local and national economies. The economic cost (direct costs include the costs of care and control of malaria, and indirect costs include the losses in productivity and lost future earnings from death) of malaria in South Africa is conservatively estimated to be around R124 million (US$20 million) in 1997/98.

Outbreak affect countries socially ?

It kills at least 1 million people every year in Africa alone. Of the 300 million to 500 million annual cases of malaria, 90 percent occur in sub-Saharan Africa. The World Health Organization (WHO) reports malaria is responsible for one in five deaths of African children under age 5 every year.Malaria takes its toll not only in lives lost, but also in medical costs, lost income, and reduced economic output. The annual direct and indirect costs of malaria.Rural and poor people are especially at risk because they are least likely to have the means to prevent and treat malaria. Children miss school because of the disease, suffer physically and intellectually, and often cannot contribute to their families' income though agricultural work. The WHO reports that many families spend up to a quarter of their annual income for malaria treatment.
