Dengue Can Recur and Be More Severe, Experts Warn
Summary
Dengue can occur more than once due to four virus serotypes, and a second infection can sometimes be more severe. Critical symptoms require immediate medical attention, and prevention through mosquito control remains essential.
Key Points
- Recovery from one dengue infection does not provide lifelong immunity.
- Dengue is caused by four related virus types, allowing for reinfection with different serotypes.
- Second dengue infections can be more severe due to Antibody-Dependent Enhancement (ADE).
- Warning signs like bleeding and severe abdominal pain require immediate medical care.
