Can dengue return? after having the severe one

Dengue: Absolutely. There are 5 different serotypes of this flavivirus and infection with one may not confer immunity to the others. Reinfection may create dengue hemorrhagic fever, a the life-threatening condition resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs.

Dengue Fever: Agree with Dr. Raff. Reinfection can occur.

See Below: Agree with Dr. Fowler. In fact a second infection can be more severe. Wish you good health!
