Climate change can lead to global outbreak of mosquito-borne diseases dengue, zika and chikungunya, warned the World Health Organization on Wednesday. The incidence of infections caused by arboviruses, such as dengue, Zika and chikungunya, has grown dramatically around the world in recent decades. About half of the world's population is now at risk of dengue with an estimated 100-400 million infections occurring each year.
