"Dramatic downward trend" in malaria cases over the past 15 years

October 02, 2015
The report, “Achieving the malaria MDG target”, found malaria death rates have plunged by 60% over the past 15 years. Children under five account for more than two-thirds of all deaths associated with malaria. Between 2000 and 2015, the malaria death rate for under fives fell by 65%.
"Global malaria control is one of the great public health success stories of the past 15 years,” said Dr. Margaret Chan, Director-General of WHO. “It’s a sign that our strategies are on target, and that we can beat this ancient killer, which still claims hundreds of thousands of lives, mostly children, each year.”

Malaria is caused by a parasite called Plasmodium, which is transmitted via the bites of infected mosquitoes. In the human body, the parasites multiply in the liver, and then infect red blood cells. 

Symptoms of malaria include fever, headache, and vomiting, and usually appear between 10 and 15 days after the mosquito bite. If left untreated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs. In many parts of the world, the parasites have developed resistance to a number of malaria medicines.

According to WHO, the number of countries on the verge of eliminating malaria is increasing. In 2014, thirteen countries reported zero cases of the disease and six countries reported fewer than ten cases. The fastest decreases in cases of malaria were seen in Central and Eastern Asia.

New research from the Malaria Atlas Project – a WHO Collaborating Centre based at the University of Oxford – shows that insecticide-sprayed bed nets (ITNs) have been “by far the most important intervention” in malaria control, accounting for the prevention of 68% of malaria cases since 2000. 

Despite this progress, about 3.2 billion people – almost half of the world’s population – are at risk of malaria. In 2015 alone, there were an estimated 214 million new cases, and approximately 438,000 people died of this disease.

The WHO Global Technical Strategy for Malaria (a new 15-year road map for malaria control), adopted in May 2015, aims at a further 90% reduction in global malaria incidence and mortality by 2030.
