For decades, researchers have been trying to uncover the cause of nodding syndrome, a mysterious and deadly form of epilepsy that only affects children on the African continent. In a collaboration between Belgian and African scientists, researchers from the University of Antwerp have now discovered the root cause of the disease. In a cascade of events, nodding syndrome is triggered by another disease called river blindness, which in turn is caused by parasitic worms spread by blackfly bites. As complicated as it sounds, this is great news for the children, as it means that nodding syndrome can easily be controlled by administering the anti-parasitic drug ivermectin and exterminating blackflies.

With COVID-19 cases soaring into the millions, and a vaccine still a long way off, patients are desperate for a treatment. In response, numerous clinical trials have been initiated around the world. The majority of these trials are examining existing drugs to see if they can be repurposed to treat COVID-19. We spoke with Prof. Bart Lambrecht, pulmonologist at Ghent University Hospital (UZ Gent), about some of the clinical trials taking place here in Belgium.
