Dengue Fever: Statistics and Key Facts
Dengue is a viral infection that is usually contracted when an individual is bitten by an infected female mosquito. There are 4 dengue virus serotypes, meaning it is possible for one person to get infected 4 times. Once an individual is infected with one type, they develop lifelong immunity to that specific serotype. However, if they are re-infected with a different serotype, they are more at risk of developing severe dengue, which can be life-threatening .
The WHO estimates that 390 million dengue virus infections occur every year, 70% of which are in Asia. What’s most troubling is that the number of cases continue to rise annually, with 2019 being the year with the largest number of dengue cases to ever be reported globally.
