There has been a ten-fold increase in dengue cases between the years 2000 and 2019, according to an analysis by the World Health Organization (WHO). The reported cases have gone up from 500,000 to 5.2 million during this period, the WHO said. The actual number of cases would be higher as the infection is asymptomatic in most cases and it is not a notifiable disease in many countries.
