The World Health Organization (WHO) has issued a warning about new cases of a serious "dengue fever" that are spreading to previously unaffected areas around the world, with the primary causes being water and mosquitoes.

According to the organization, 5% of severe dengue fever cases require hospital treatment as they can be fatal. It is concerning that these cases have started appearing in locations where the disease was not previously present, such as Spain or Bhutan.

Dengue fever is a viral illness transmitted by mosquito bites. Its symptoms include vomiting, gum bleeding, plasma leakage, and, in some cases, organ failure. It can be transmitted from one person to another through infection.

According to specialized doctors, the reason for the emergence of dengue fever cases in countries where it has not previously spread is the increased quantity of stored water, which creates more breeding grounds for mosquitoes. These mosquitoes adapt and spread the disease in new areas.

Furthermore, controlling dengue fever is challenging because mosquitoes have adapted well to urban areas. Their eggs can remain dry for several months and hatch as soon as they come into contact with water.
