It is said that predictions are very difficult – especially when they concern the future. No doubt Scott O’neil and his Eliminate Dengue team never would have expected to be where they are now 10 years ago. In contrast, those who dreamt of releasing malaria-refractory transgenic mosquitoes two decades ago in the Tucson desert would have been surprised too.
This week I was contacted by Dr. Dana Dalrymple with a very unusual offer. He wishes to provide all MalariaWorld subscribers free access to his book 'Artemisia annua, Artemisinin, ACTs & Malaria Control in Africa' published just seven months ago. This is truly remarkable and we highly appreciate this gesture!
Artemisia annua tea: prophylaxis against malaria
In July I was approached by a Dutch radio station that brought a most interesting YouTube video to my attention. It features an award winning idea by Go Outside magazine (based in Brazil), this being the 'Repellent radio'. It was created by the Sao Paulo-based advertising agency Talent, and it won the Radio Grand Prix award 2012 at the Cannes Lions International Festival of Creativity. Take a look...

For most of us, it’s entirely logical that medical practitioners should be familiar with the latest scientific knowledge and evidence-based practices in order to treat ailments. This forms our fundamental basis of trust in medical professionals. If your doctor suggests a CT scan or drug X, you follow that advice on the basis of trust. So how would you feel if your doctor confesses that he lacks the latest scientific information about your condition?

I am not sure if at all you are familiar with TED, which stands for Technology, Entertainment, and Design, with its motto 'Ideas worth spreading'. I love to watch these talks, they inspire me, provide energy, and are often fun to watch.
Yesterday I watched the talk by Margaret Heffernan with the title 'Dare to disagree'. This is a very interesting talk and it made me think of the world of malaria. First, have a look at what she has to say...
People tend to do quick cost-benefit comparisons of bednets vs metallic screens, and make some large mistakes. Bednets are temporary, protect only against anopheline mosquitoes which bite at night, and are used only about one-third of the time. One of the reasons for their misuse is that they are suffocating to sleep under.
Seldom does so much news appear so suddenly that it grabs me by the ears and says, “You MUST write a blog. Now!” Following are the highlights of recent publications that reflect the maturing potential for genetic control to affect malaria and dengue transmission. If you’re interested in a quick summary of recent news and views, here it is.
Last week I was in Geneva, trying to understand the WHO fight against malaria, when - to my delight - the folks at CERN announced that they had found the Higgs Boson! In fact we were driving out near Geneva Airport, right over the Super Hadron Collider, when they made the announcement. But it made me wonder about WHO. Why was it easier for CERN to find the Boson than for WHO to suppress malaria?

More than a decade after implementation, the global malaria control strategy has proven woefully inadequate. It has reported expenditures exceeding several billion dollars and relies heavily on passive methods like mosquito nets but has been unable to meet its goals of reducing an annual morbidity rate that continues to hover around half billion and a mortality rate equivalent to six Jumbo jetliners crashing daily. The time has come to get serious about this problem. Malaria vector control programs around the world need to be placed under trained public health entomologists who can implement comprehensive mosquito population suppression methods and deploy truly integrated vector control systems. Continuing in the current path is unacceptable and wastes quickly dwindling, limited resources.
Whenever I teach on the history of malaria, I talk about the different time periods when certain ideas were fashionable and implemented, and then disappeared, and sometimes came back much later.
Take the 'chloroquine era'. Discovered by Bayer scientists in the early 1930s and saved millions of lives around the globe, followed by resistance popping up in SE Asia and Colombia in the late 1950s. Resistance spreading to Africa in the late 1970s, and its use now largely reduced. End of the 'chloroquine era'.

Insecticide resistance and the limits of our current vector control tools threaten our global progress against vector-borne diseases. Innovative vector control tools are therefore urgently needed, but some technical, financial and programmatic barriers may hinder innovation. In October 2011, a gathering of stakeholders including individuals from IVCC, WHO, donor institutions, industry, and other partners issued a joint call for a mapping of the current process to introduce new vector control tools for public health and the need to identify the challenges faced today in this process.
E-interview with Marc Coosemans, senior full professor, medical entomology unit, Institute of Tropical Medicine, Antwerp, Belgium. The team and collaborators of Prof. Coosemans were recently awarded a $ 3 million grant by the Gates Foundation, to study the effects of community-wide use of topical repellents on malaria in Cambodia, when used in conjunction with insecticide-treated bednets.
A friend and colleague asked me whether all the media excitement about transgenic mosquitoes represents real accomplishments that beat non-transgenic sterile insect technique (SIT). Good question. In the first of a two-part blog, I’ll tell you where I think things stand, first in SIT. In the second part, I’ll look at population replacement.
Last week, publication of the WHO report on insecticide resistance did not go unnoticed. It was taken up by the journal Nature, and in a news article by Amy Maxmen some truly remarkable statements by some of the leading malaria researchers are to be found. I trust that these people saw the article and gave consent to its publication, so any quote in it must really have come from them. Be prepared...
This week, Harvard School of Public Health's Associate Professor Winston Hide made a courageous move: he resigned from being the associate editor of the journal Genomics (an Elsevier journal). Why? Because he could no longer accept the inability of scientists in developing countries to access full articles stuck behind paywalls thrown up by publishers. A bold and remarkable step. He published the rationale for making this decision this week in the Guardian.
This week WHO reiterated the fragility of the gains the world has made over the last decade through intense deployment of vector control in the fight against malaria. Reuters published an online article on the matter titled 'Insecticide resistance threatens malaria fight'. In it, WHO Director General, Margaret Chan, warns of the seriousness of the situation in Africa and India. Apparently, in ever more places the toolbox, filled with four classes of chemicals, is gradually emptying.
Last week, WHO published a statement regarding the potential of larviciding for malaria control in Africa. This followed the circulation of a draft version of the statement in August 2011. That draft was sent to a limited group of people (how many I don't know) for comments (including myself). I attach the official version to this editorial.
This is the last week before you will have to log in in order to have access to the platform (as of 29 March 2012). That's why we here explain to you what to do:
1) If you never had an account with MalariaWorld
2) If you registered before but forgot your username and/or password.
The editorial below was written by Camilla Beech, Regulatory Affairs Manager, Oxitec Ltd, UK, partially as a response to a recent editorial by Guy Reeves, on regulatory aspects of GM mosquitoes.
Having spent over 10 years developing novel genetic approaches to control insect pests, we’re acutely aware of the importance of proceeding with caution, of doing so in a transparent and open manner, and of engaging in the most effective way possible with the diverse communities who have an interest in the development and use of these new technologies.
The article below was written by Dr. Bill Jobin and first posted as a comment under the most recent poll. I elevated it to a Guest editorial.
It is unfortunate that we have recently seen a great deal of confusion about the amount of malaria in Africa. The confusion arises because most of the people making the estimates are not scientists but artists; computer artists. It would be better if we relied on scientists. Computer artists, using their own data and their own inspirations, get varying answers and generate conflicting maps and graphs. But scientists, using standardized techniques and randomized sampling, get the same answers, no matter who is doing the work. We urgently need accurate numbers on malaria...
