Global malaria death toll falling

Mosquito Anopheles mosquitoes spread malaria

We all like reports of dramatic medical and scientific breakthroughs but the reality is that most developments are incremental. As a result, important issues can get overlooked.

Take malaria. Deaths from the parasitic infection - which is spread by the bites of infected mosquitoes - have been falling steadily since around 2004. Only a few years ago it was said that the disease killed one child every 30 seconds. I remember using this figure on a trip to Ghana in 2006. By 2009 the estimate was down to one child dying every 45 seconds.

"It is now more likely that malaria kills a child every sixty seconds," according to Dr Richard Cibulskis, the lead author of the World Malaria Report.

He explained some statistical factors are at work here - in part the fall is due to a downward revision in overall global childhood mortality.

Updates in surveillance numbers in recent years has also led to a fall in the global estimate of cases. Assessing the burden of malaria is not straightforward. Many Africa countries do not have strong disease surveillance systems so cause of death data is not always well recorded. This means that surveys and what are called 'verbal autopsies' - descriptions of symptoms given by parents - are sometimes used.


Despite difficulties in compiling the statistics, there is a clear, and welcome, downward trend in deaths. It is estimated that malaria killed 655,000 people in 2010, compared to 800,000 in 2004.

"It is remarkable progress," said Dr Cibulskis. "When I began working in the malaria field in Africa we were fighting a losing battle. Now all that has changed and the risk of dying from malaria has fallen by a third in a decade."

The improvement is down to several factors. A total of 145 million long-lasting insecticide-treated nets were delivered to sub-Saharan Africa last year, a huge increase on 2009. Spraying the walls of homes with insecticide is another effective means of reducing malaria.

Once infected, it is vital that treatment begins quickly. Rapid diagnostic tests are being increasingly used. These detect the presence of malaria parasites in the blood, often via a simple finger-prick test.

The use of artemisinin-based combination therapies has transformed the treatment of the disease in the past decade.

Children who are seriously ill can make a dramatic and rapid recovery after just a couple of days of taking the drug.


There continue to be worrying signs of drug resistance, first confirmed on the Cambodia-Thailand border in 2009 and now suspected in Burma and Vietnam.

To reduce the chances of drug resistance spreading it is vital that artemisinin-based treatments are giving in combination, and yet 25 countries - most in Africa - still allow the marketing of monotherapies. The WHO says most of the manufacturers are in India.

There are promising indications from trials of a vaccine against malaria, but this will be only part of the solution to tackling this preventable infection.

There are concerns about the global funding of malaria control which is expected to peak at $2bn this year and fall to $1.5bn in 2015. The UK government is notable among donors in that its support is pledged to increase in the coming years.

Malaria remains a major public health threat. Nine out of 10 deaths are in Africa and the vast majority are children under five.

Four countries - Armenia, the United Arab Emirates, Morocco and Turkmenistan - have been certified free of malaria since 2007. But around more than three billion people in around 100 countries remain at risk. The battle against malaria has a long way to go.

    Some data related to the continuing saga of resistance to anti-malarial drugs can be browsed on the WWARN website:

    The drug resistance is a real concern, the climate changes will bring ever more human populus into contact with this terrible disease.

    There is no quick fix for this problem, and in this economy who wants to spend R&D money on it? Only philanthropy on a grand scale may have enough of a chance to make a real difference.

    It can only be hoped that the WHO warnings are noted & that steps are taken to address the going resistance. To those who question the value of overseas aid this provides a great example of what can be achieved. Thank you Fergus.

    Malaria kills an average of about 250,000 children yearly in Nigeria; it kills more than HIV/AIDS & tuberculosis put together. It also kills a lot of pregnant women. In fact, 11% of death in these women results from malaria fever & complications. In hospitals, you will see a great number of children suffering from what we call cerebral malaria, parasite entering the brain: It kills.

    In Nigeria commitment is pathetic. e.g. Last 2 years, population @ 157M, minimum required @ N20 billion. The Fed. Govt committed paltry N200 million. 2011 Appropriation is @ N600 million - not even enough for mosquito-treated nets. Donations are less 7% of requirements.
    Key problems: corruption, lack of political will, resources not properly utilised.
