A wake-up call for all of us

December 27, 2012 - 12:34 -- Bart G.J. Knols

Last week showed unambiguously that unless the world pulls up its sleeves, the hard-won gains of the last decade may go up in smoke. 'The world' in the previous sentence is you, us, all of us engaged as professionals in the field of malaria. MalariaWorld has put out warning signals over the last three years, about the problems with drug resistance, about artemisinin resistance in SE Asia and the risk of it escaping to other parts of the world, about impregnated bednets being shipped to parts of Africa where full-blown resistance against pyrethroids occurs, about counterfeit drugs undermining curative treatment and increasing the risk of resistance popping up, about the difficulties of vivax elimination, about the problems with zoonotic malaria, about...the list is endless I'm afraid... 

Saving the failing WHO fight against malaria in Africa

December 21, 2012 - 17:20 -- Bart G.J. Knols

This contribution was posted as a comment by Dr. Bill Jobin, Director of Blue Nile Associates in response to the meeting report of the WHO Malaria Policy Advisory Committee that was held in September 2012.

It is ironic that a WHO policy meeting in September will ignore the terrible truth outlined by the WHO  Director General Margaret Chan in December - that the malaria program is going to crash.....  With due respect to Rob Newman and Margaret Chan in Geneva, I would like to suggest 6 steps to save their Global Malaria Program.  My suggestions are simple applications of rational approaches to a problem, the same things we would do with any other problem in life.  It does not take a Rocket Scientist to figure this out.  Simply put, I suggest that they Narrow their Focus, Expand their Base, add 2 more Components to their Strategy, establish a valid Monitoring and Evaluation system, and set Realistic Goals against which they can Measure their Progress ......

Update: LG Electronics guilty of 'counterfeit vector control'?

December 20, 2012 - 10:55 -- Bart G.J. Knols

 

The BBC published an article on the myths of mosquito repellers based on ultrasounds following articles on MalariaWorld. Amazingly, in spite of the massive evidence that is there to show that ultrasounds do nothing to repel mosquitoes, the electronics giant LG has started to market an air conditioner in Nigeria that incorporates ultrasound. The company published a news release titled 'LG fights malaria in Nigeria with hi-tech air conditioner'... 

It’s the most wonderful time of the year…is it still?

December 18, 2012 - 21:11 -- Bart G.J. Knols

Every year in December, the global malaria community eagerly awaits the World Malaria Report published by the World Health Organization. Every year countries around the world report their status of the disease, and year after year over the last decade the World Malaria Report was like a Christmas gift. Our collective efforts were paying off, both mortality and morbidity was on the decline, and scaling up of the tools yielded what we expected: A massive reduction in malaria. But this year’s end is different…

Should Artemisia annua (wormwood) tea be used as a prophylactic in endemic countries?

December 18, 2012 - 14:56 -- Bart G.J. Knols

This expert blog was contributed by Dr. Merlin Willcox, Honorary Secretary of the Research Initiative on Traditional Antimalarial Methods (RITAM), in response to the outcome of a poll on MalariaWorld and recent contributions regarding the use of Artemisia tea as a remedy for malaria.

As a scientist and medical doctor, I am interested in herbal medicines for malaria. No one can deny that they have been the source of the two most important and effective families of antimalarial drugs. Furthermore many people still rely on various herbal remedies for treating uncomplicated malaria. Much of my own research has aimed to investigate these objectively and to find the most effective remedies.
 
Artemisia annua is a very interesting plant and is the source of the most powerful antimalarial drug ever discovered, artemisinin. There are a few clinical trials which even show that it can be used as an “emergency, first-aid” treatment for malaria in semi-immune adults. However there are no published clinical trials which prove effect on the prevention of malaria, and no published clinical trials which demonstrate effectiveness in young children...

Rob MacLennan: Jury voted with their 'gut'

December 12, 2012 - 10:31 -- Bart G.J. Knols

Yesterday, BBC's William Kremer published an excellent article about the myths surrounding ultrasounds as repellents against mosquitoes. We both talked many times about these myths and he researched the matter thoroughly. Nothing but praise for this piece of great journalism. But for us here at MalariaWorld the story isn't over yet, because the Cannes Lions Festival is simply waiting for the media storm to blow over and then move on with business as usual...

A "vaccine" against malaria from Africa: ARTAVOL®.

December 5, 2012 - 17:33 -- Bart G.J. Knols

The guest blog below was provided by Dr. Pierre Lutgen.
 
Since 5 years a group of scientists at the Ministry of Health of Uganda is working on plant extracts which might have a prophylactic effect against malaria. Since 12 months a product is available in the pharmacies of Uganda. The product has been released after clinical and community trials over 3 years which have demonstrated that if taken regularly during one year it renders a person immune against malaria. It also reduced the asymptomatic malaria cases in an adult population by 60%.

Cinderella science

December 1, 2012 - 14:43 -- Bart G.J. Knols

The guest blog below was contributed by Prof. Matt Thomas, of Penn State University. Read more about Professor Thomas here.

Everybody would like to see the burden of malaria reduced and while there might be some disciplinary biases, most would agree that long-term sustainable management of malaria requires integrated strategies built on solid foundations of local knowledge and capacity. 
 
Of the broad approaches available (and by available I include potential tools somewhere along the development pipeline), vector control is clearly pivotal. This is not to diminish the importance of other technologies, such as drugs or diagnostics, but much of the recent decline in malaria can be attributed to wide-scale implementation of vector control tools such as long lasting insecticide treated bed nets (LLINs) and indoor residual insecticide sprays (IRS). Furthermore, in nearly every historical case where malaria has been substantially reduced or locally eliminated, vector control has been key. 

Free Book for MalariaWorld Members!

November 27, 2012 - 21:45 -- Bart G.J. Knols

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!

In his email he said: "This will get it to the heart of the international malaria community and doubtless reach many who otherwise may not have heard of, or had access to, it." That is the spirit of truly open and global collaboration we aim to achieve with MalariaWorld. So a big 'Thank you' to Dr. Dalrymple! If you download it, why not send him a private message through the platform (available to subcribers) to let him know you appreciate his action...

Mercedes-Benz should win Cannes creativity award!

October 23, 2012 - 22:00 -- Bart G.J. Knols

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...
