Testing drugs that could treat dengue
Developing a direct treatment for dengue fever remains difficult due to the virus's short duration in the body and the complex inflammatory response it triggers. Experts note that treatment must be administered very early to be effective, which is often hindered by delayed diagnosis.
Why it matters
Dengue fever is a significant global health challenge, and understanding the barriers to treatment is essential for future medical research and public health policy.
Although the dengue virus was identified in the early 20th century, and the disease itself known since at least the time of the Jin Dynasty in China (265-420 AD), there is still no direct treatment for dengue fever.
What doctors currently prescribe for patients is supportive treatment to help manage symptoms and prevent potential complications.
There are a number of reasons why it is so challenging to come up with a dengue treatment.
According to Drugs for Neglected Diseases initiative (DNDi) Dengue Global Programme head Dr Andre Siqueira, one challenge is the length of time the dengue virus is actually in the body.
“The dengue virus stays in the body for around 10 days, but usually after the onset of fever, it’s about four to five days on average.
“So that means that we need to start treatment very early to have an effect,” he explains.
