Yellow fever threat looms: Scientists warn of global crisis

Scientists are warning that yellow fever, a dangerous disease transmitted by mosquitoes, could potentially ignite a global pandemic. Increasing urbanization and enhanced travel activities are raising the risk of the virus's spread.

Yellow fever, caused by the YFV virus, initially presents with symptoms such as fever, chills, and muscle pain. However, in severe cases, it can progress to internal bleeding and organ failure.

Increased threat in the Asia-Pacific region

Although yellow fever has historically been endemic in Africa, as well as South and Central America, there is growing concern about its potential to reach the Asia-Pacific region. As far back as 1923, epidemiologist H.R. Carter warned of such a scenario.

The current risk is heightened due to global travel. In 2019, over 4 billion people traveled between regions where the virus is prevalent and areas where mosquitoes could potentially spread it.

The yellow fever vaccine, which provides lifetime immunity, is available but in limited supply.

Scientists are emphasizing the necessity of improving vaccine distribution and implementing more effective mosquito population control measures to prevent a potential epidemic. "We must act now," urge the authors of the study published in "npj Viruses."

A yellow fever pandemic could have tragic consequences

Researchers caution that a yellow fever pandemic could be far more devastating than the COVID-19 pandemic. The high mortality rate and the rapid transmission of the virus could lead to a severe global health crisis.

In the past, initiatives like the Yellow Fever Initiative vaccinated over 105 million people in West Africa, significantly reducing the incidence of the disease.

Yellow fever is an acute viral hemorrhagic disease named for jaundice, one of its symptoms. Symptoms include fever, headaches, nausea, and vomiting. A small number of patients may develop severe symptoms, with half of them succumbing within a week.
