Impact of Malaria and Vestigard Nets on Papua New Guinea
In Papua New Guinea, efforts to combat malaria were initially successful with a significant decrease in cases, thanks to insecticide-laced nets from Vestigard. However, researchers found a concerning trend as malaria cases started to increase again, indicating a reversal in progress. Further investigation revealed that changes in the manufacturing process of the nets led to a decrease in effectiveness, ultimately thwarting the country's advancements towards malaria eradication.
Consequences of Insecticide Treated Nets
The introduction of insecticide-treated nets revolutionized malaria prevention, especially in regions like Papua New Guinea. Previously, nets had to be manually treated, which was labor-intensive and less effective. The pre-treated nets significantly reduced mosquito populations and malaria cases. However, shifts in manufacturing practices, particularly the replacement of effective chemicals with cheaper alternatives, compromised the nets' efficacy over time.
Importance of Maintaining Quality in Disease Prevention Products
The Papua New Guinea case serves as a cautionary tale on the trade-off between cost and quality in public health products. While affordability is a consideration, compromising on quality can have detrimental effects on disease control efforts. The incident with Vestigard underscores the significance of ensuring rigorous quality standards in manufacturing essential items like mosquito nets to sustain effective disease prevention measures.
For years, it seemed like Papua New Guinea was on a course to stamp out malaria. In 2010, the total number of suspected malaria cases in Papua New Guinea was 1.7 million. By 2015, the number had been cut nearly in half. Experts believed the country could see a malaria-free future as soon as 2030. But then, something changed—and cases started climbing again, as quickly as they had fallen.
In today’s episode of the Big Take podcast, Bloomberg health care reporters Anna Edney and Michelle Fay Cortez unpack how a single business decision made by the world’s biggest manufacturer of bed nets reversed years of work to eradicate malaria in a country that—at least for a while—was on track to beat it.
