" MANILA, Philippines : The rise in dengue cases not just in the Philippines but in other parts of Asia has prompted the World Health Organization (WHO) this month to declare that dengue is one of the fastest-emerging infections in the world.
In a statement, WHO said "much of Asia continues to be in the grip of dengue fever, with the number of hospitalizations and severe cases growing."
The agency said some countries have reported significant increases in dengue outbreaks as compared to the same period last year.
It also said that an estimated 2.5 billion people are at risk globally from dengue, and more than 70% of them reside in the Asia Pacific region.
Among the badly affected countries cited are the Philippines, Lao People's Democratic Republic, Malaysia, and Vietnam.
Singapore also has dengue cases but according to WHO, it is experiencing a declining trend, with total number of cases over the years continuing to fall."
