 [Epoch Times] The World Health Organization (WHO) has warned that cases of dengue fever could reach record highs this year. Dengue rates are rising globally, with reported cases since 2000 up eight-fold to 4.2 million in 2022, a WHO official said on July 21.
Dengue fever can be caused by the dengue virus 1, 2, 3, or 4, according to the U.S. Centers for Disease Control and Prevention (CDC). The illness is transmitted primarily via the Aedes aegypti mosquito, which the CDC says is active during the day.
The most common symptom of dengue is a fever with nausea, vomiting, rash, aches, and pains, including eye pain, muscle pain, and bone pain. Symptoms generally last between two and seven days, the CDC says.
Most patients who contract dengue fever recover without hospitalization, said Dr. David O. Freedman, a former professor with the University of Alabama at Birmingham.
But the rest of the world needs a vaccine!
Meanwhile, drugmaker Takeda Pharmaceutical Co. said earlier this month that it has voluntarily withdrawn its application for its dengue vaccine candidate, following discussions with the U.S. Food and Drug Administration. The Japan-based company cited data collection issues, which cannot be addressed within the current review cycle.
Takeda’s vaccine, branded as QDENGA, was authorized in the European Union last year for use in those aged 4 and older to prevent any of the four so-called serotypes of dengue. It has also been approved in the UK, Brazil, Argentina, Indonesia, and Thailand, according to the company.
Sanofi’s Dengvaxia, the world’s first dengue vaccine, was licensed in 2015. However, the use of the French company’s vaccine was scaled back considerably after it emerged that it increased the risk of severe disease in "seronegative" children, or those who had no prior dengue exposure when they got the shot.
