Dengue Virus Spreads: The World Health Organization (WHO) has expressed growing concern over the worldwide spread of the Dengue virus. The number of people contracting the disease is increasing globally, and the risk of infection is also growing in Europe, according to WHO.
Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection and may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash. In severe cases, it can develop into life-threatening dengue hemorrhagic fever or dengue shock syndrome.
The disease is now endemic in more than 100 countries, with 2.5 billion people living in areas where it is prevalent. Outbreaks have occurred in Southeast Asia, the Americas, the Pacific, Africa, and the Eastern Mediterranean.
The WHO has been working with countries to control the Aedes aegypti mosquito, the primary vector of dengue. Efforts include eliminating mosquito breeding sites and improving community awareness. However, these measures have not been sufficient to control the disease.
The increase in global travel and trade, urbanization, and climate change have all contributed to the spread of the Aedes mosquito and the dengue virus it carries. The WHO has called for more research into dengue and the development of a vaccine.
The organization is also urging people to protect themselves from mosquito bites by using insect repellent, wearing protective clothing, and ensuring rooms are fitted with screens to keep mosquitoes out.
The spread of the dengue virus is a stark reminder of the ongoing threat posed by mosquito-borne diseases. As the world continues to grapple with the COVID-19 pandemic, it is crucial that we do not lose sight of other significant health challenges.
The WHO’s warning serves as a reminder that global health security is about more than just one disease. It is about a comprehensive approach that considers all potential threats and ensures we are prepared to respond to them.
