Time to give spatial repellency its rightful role in vector control

June 19, 2012 - 19:19 -- Bart G.J. Knols

The following Guest editorial was provided by Richard Tren, Kimberly Hess, and Donald Roberts.

Progress is being made against malaria. As reported by the World Health Organization (WHO), malaria cases have declined by more than 50% between 2000 and 2010, and malaria-specific mortality has declined by 26% [1].  These gains are mainly due to the use of insecticides to control disease-spreading insects (vector control) through insecticide-treated bednets and indoor residual spraying (IRS). Despite the importance of public health insecticides in vector control, there is very little appreciation and understanding of how insecticides actually work in disease prevention.

Can we maintain effectiveness of the tools?

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.

WHO should measure the prevalence of malaria in Africa

March 8, 2012 - 19:56 -- Bart G.J. Knols

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...
