Climate change spurring surge in dengue, chikungunya: WHO

Live Mint  

The World Health Organization warned Wednesday that dengue and other diseases caused by mosquito-borne arboviruses were spreading far faster and further amid climate change, warning global outbreaks could be looming. Experts with the United Nations health agency sounded the alarm over swelling numbers of cases of dengue and chikungunya, and warned new epidemics of zika could also be expected. "Climate change has played a key role in facilitating the spread of the vector mosquitoes," said Raman Velayudhan, who coordinates WHO's dengue and arbovirus initiative. He and colleague Diana Rojas Alvarez, WHO's technical lead on chikungunya and zika, stressed the need for urgent action to rein in the spread of the mosquitos, amid fears of larger outbreaks in new areas.
