Dengue virus on the rise in Nepal

Accounting for nearly 100 million symptomatic cases worldwide annually, dengue virus continues to expand to new territories. Nepal, a Himalayan country which lies between the world's two most populous nations—India and China—had the largest dengue outbreak in 2019 with more than 14 600 cases and six deaths. With altitudes from 70 m to the highest point in the world and climate types ranging from dry to polar, Nepal is a unique environment to study the changing distribution of infectious diseases.
