A 19-year-old man in Bolivia has died from dengue fever, marking the first death from the disease since massive floods began ravaging the country in November.

The teenager who died was from the northwest part of Bolivia, among the areas hardest hit by the torrential rains that have killed 53 people nationwide.

Bolivia has declared a national state of emergency over the flooding, which has left tens of thousands of people homeless.

With more than 100 cases of dengue fever recorded around the country, authorities have issued health warnings, fearing epidemics due to persistent flooding.
