![Volumetric differences seen in the brains of mice treated with anti-malarials with rosiglitazone compared to mice treated with anti-malarials alone.](https://www.grandchallenges.ca/wp-content/uploads/2014/04/LenaBlog_2.png)
On World Malaria Day I would like to celebrate the successes of the global efforts to control and eliminate malaria that have significantly reduced malaria mortality worldwide. I would also like to note that despite all these great efforts, well over half a million people, mostly children under the age of 5, died of the disease last year. This is an unacceptably high number.
