Mismatch Between Malaria Vaccines and Local Parasite Strains in Ethiopia show art 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...

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...

Can AI identify mosquito species? VectorCAM, a pocket-sized device, uses machine learning to differentiate species with 95% accuracy, enhancing malaria surveillance efforts 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...

The prevention of malaria depends upon multiple layers of interventions that work together to reduce cases and deaths. But what makes someone decide to sleep under a bed net, or apply an insecticidal cream? What makes one person take up more interventions than another? How influential are government-accredited health experts versus friends and family?  With András Vörös, an Associate Professor in Quantitative Methods at the University of Birmingham and Elisa Bellotti, a Senior Lecturer in Sociology at the University of Manchester.

Malaria prevention depends on the adoption of multiple behaviors –  like sleeping under a bednet and wearing clothes that cover the skin. Researchers find that conversations with people in one’s own social circle are the strongest factors that influence behavior uptake. Transcript Malaria prevention depends on the adoption of multiple behaviors –  like sleeping under a bednet and wearing clothes that cover the skin – to reduce exposure to infectious mosquitoes. Theories of ‘social influence’ are often used to explain the uptake of single behaviors, in which an...

Transcript

The effects of climate change on malaria are becoming clearer. Anopheles stephensi – an urban form of the malaria mosquito – is changing its geography, moving from Southeast Asia to parts of Africa and India. To investigate the link between temperature and malaria, between 2021 and 2022 researchers in Chennai, India placed data loggers that recorded temperature – and the daily range of temperature - in both indoor and outdoor settings. They took those measurements and compared them to ten years earlier, from 2012 to 2013. The daily temperature range of indoor asbestos structures increased from 4.3 to 12.6 degrees Celsius — compared to a marginal increase in other structures. Importantly, an increase in temperature was associated with a decrease in the incubation period – that's the time it takes for the parasite to develop in the mosquito. With invasive mosquito species entering new areas, combined with the shorter time it takes to transmit, it's becoming more clear that rising temperatures will lead to an increase in malaria cases in certain areas – and that preparation will be key.
