EXTENDED: From River Blindness to Malaria Control – The Ivermectin Story (with Carlos Chaccour and Joseph Mwangangi)
Johns Hopkins Malaria Minute
In Kwale, Kenya, where bed nets alone can’t stop malaria, researchers are testing ivermectin – a drug long used to treat parasitic infections – as a new way to kill mosquitoes. Trials show a 26% drop in malaria cases and added benefits against other mosquito-borne diseases, suggesting ivermectin could be a scalable, community-driven tool in the fight against insecticide resistance.

What Severe Malaria Cases Have In Common
Johns Hopkins Malaria Minute
Although severe malaria presents in different clinical forms – such as cerebral malaria or severe malarial anemia – a new study reveals that all severe cases have one thing in common: a shared inflammatory signature Transcript Whilst most cases of malaria are mild, some take a dangerous turn. In severe cases, the malaria parasite can overwhelm the body, disrupting the blood-brain barrier and leading to cerebral malaria, or destroying so many red blood cells that it triggers life-threatening anemia. Now, a new study has taken a closer look at this progression – from uncomplicated malaria...

Bed Nets That Target Parasites, Not Just Mosquitoes
Johns Hopkins Malaria Minute
How next-generation bed nets could stop malaria by killing the parasites inside mosquitoes, not just the mosquitoes themselves. Transcript Bed nets have long been a cornerstone of vector control. Coated with insecticide, they serve a dual purpose: preventing bites and killing mosquitoes. But what if those nets could do more – not only kill the mosquitoes, but for those they don’t kill because of increasing insecticide resistance, at least kill the parasites hidden inside them? Researchers assembled a library of antiparasitic compounds active against the form of the parasite in the mosquito...

Mismatch Between Malaria Vaccines and Local Parasite Strains in Ethiopia
Johns Hopkins Malaria Minute
A recent study in Ethiopia reveals that local malaria parasite strains differ genetically from those targeted by current vaccines, potentially reducing their effectiveness. Transcript The recent introduction of two malaria vaccines in sub-Saharan Africa represents a major success in global health, and the culmination of decades of research and development. The two jabs – RTS,S and R21 – target a protein on the surface of the malaria parasite as it enters the skin, called the circumsporozoite protein, or CSP. The vaccines are based on a specific form of CSP. The challenge is that there are...

Malaria Advocacy on Capitol Hill: Funding, Research, and Global Impact
Johns Hopkins Malaria Minute
The podcast explores the importance of advocacy for malaria research and control. It follows over 120 advocates gathering in Washington, DC, as part of the ‘United to Beat Malaria’ campaign, urging Congress to continue supporting global malaria efforts. Key topics include: The US President’s Malaria Initiative (PMI), founded in 2005, which provides bed nets, test kits, and treatments to combat malaria The role of global partnerships, including the Global Fund, in distributing resources efficiently. How Uganda’s malaria response is supported by international funding for the...

Transcript
Not all mosquitoes are created equal. Of the more than three thousand species, only a limited number of the Anopheles genus can transmit malaria. Even within that subset, subtle physiological differences affect how malaria spreads. Some mosquitoes prefer to bite indoors, while others outdoors. Some need large bodies of water to breed, while others only need a small puddle. Distinguishing these species is critical for effective malaria control—whether using bed nets, indoor spraying, or outdoor larval management. But identifying them by eye takes expert, entomological knowledge. Could AI help? The VectorCAM team at Johns Hopkins is working on just that. Their pocket-sized device uses a small light and magnifying lens, allowing a phone camera to capture close-up images of mosquitoes placed on slides. With up to 95% accuracy, it can identify mosquito species based on morphology in seconds. The hope is that VectorCAM will help health teams better understand mosquito populations, paving the way for more targeted and relevant malaria control efforts.
