The World Health Organization (WHO) has issued a warning about impending global epidemics of dengue fever and other diseases caused by mosquito-borne arboviruses as a result of climate change.

In an interview, WHO health experts warned of an increase in dengue and chikungunya illnesses in many parts of the world, as well as the potential for new zika epidemics.

All of these diseases are caused by arboviruses, which are spread by Aedes aegypti mosquitoes and have spread to new areas as temperatures rise.

According to the WHO, 129 nations are in danger of dengue, including 100 where the disease is endemic.

Meanwhile, chikungunya, which has been documented in 115 countries since its discovery in 1950, is experiencing an outbreak.

As fears of future outbreaks mount, Velayudhan and Diana Rojas Alvarez, WHO's technical heads on chikungunya and zika, have called for immediate action to halt the spread of the virus-carrying mosquitoes.

Meanwhile, Alvarez said that approximately 135,000 cases have been reported throughout the Americas this year, compared to 50,000 cases reported in the first half of 2022.
