Indian Ocean temperature and Dengue Intensity

May 14 , 2024 224 days 299 0
  • Researchers have found a potential link between anomalies in sea-surface temperatures in Indian Ocean and the intensity of dengue epidemics globally.
  • The link is likely due to its influence on regional temperatures through teleconnections, large-scale atmospheric patterns that can transfer heat and moisture across vast distances.
  • Dengue is a viral infection transmitted through the bite of infected Aedes species mosquitoes.
  • Before 1970, severe dengue outbreaks were only reported in nine countries.
  • But now it affects nearly half of the world’s population, with an estimated 100–400 million infections occurring each year.
