He said that severe symptoms are more likely when a dengue infection of a particular sub-variety meets a victim whose previous exposure to a different dengue virus has produced a particular set of antibodies.
"And if you have a certain combination of that, you're more prone to get severe forms of the disease."
Henn says the findings of his study have implications for the so-far unsuccessful efforts to develop a dengue vaccine. For example, the vaccine may have to be modified to account for subtypes of the virus that dominate in a particular area.
