What is a dengue duo?

A dengue duo typically refers to the co-circulation of two different serotypes of the dengue virus, which can lead to more severe forms of the disease if a person is infected with a second serotype after recovering from the first. This phenomenon increases the risk of dengue hemorrhagic fever or dengue shock syndrome, making it crucial for public health monitoring in affected regions. Understanding the dynamics of dengue duos helps in implementing effective prevention and control measures to reduce outbreaks.
