Dengue fever is surging worldwide, driven by rising temperatures and weather extremes. Biotech is helping us fight back, Bio.News reports.
What is dengue? A viral infection spread from Aedes aegypti mosquitoes to people, dengue causes high fever, headache, severe muscle and joint pain, nausea, and rash. While the virus usually causes little or no symptoms, it can be fatal.
In a “horror year,” dengue cases increased 30% year-on-year in 2023, according to Save the Children, while the World Health Organization (WHO) says over 5 million dengue cases caused at least 5,000 deaths.
We have a vaccine: BIO member Takeda’s QDENGA® earned European Medical Agency approval last year.
And we have solutions for mosquitoes: The World Mosquito Program breeds Aedes aegypti mosquitoes carrying a naturally occurring bacteria that reduces the mosquitoes’ ability to transmit the virus, while UK-based Oxitec genetically engineered male Aedes aegypti mosquitoes to carry a gene lethal to female offspring, thereby limiting reproduction.
What’s next? Oxitec achieved promising results, but more research is needed to see if they can suppress the wild population.

CNN: New antibiotic uses novel method to target deadly drug-resistant bacteria, study says
“Scientists say they have developed a new type of antibiotic to treat bacteria that is resistant to most current antibiotics and kills a large percentage of people with an invasive infection. … The researchers say the approach used to inhibit the growth of Acinetobacter could help with other hard-to-treat bacteria like E. coli.”
