Dengue is currently the fastest-spreading mosquito-borne viral illness worldwide. Each year, an estimated 390 million infections occur, leading to roughly 500,000 hospitalizations and nearly 40,000 deaths. In 2023, the World Health Organization classified dengue as a Grade 3 emergency—the highest level—following a surge of outbreaks across multiple regions. India continues to shoulder a substantial share of the global burden, accounting for nearly one-third of all reported cases, with 233,519 infections and 297 deaths recorded in 2024.

While many dengue infections remain asymptomatic, the disease presents a broad clinical spectrum—from mild, unrecognized illness to severe, life-threatening complications. The progression to severe dengue is influenced by several factors, including age, prior dengue exposure, underlying health conditions, and the infecting viral serotype. Understanding these determinants is crucial for timely diagnosis, effective management, and improved outcomes.

Join us for this webinar as we explore the key drivers of dengue severity, identify high-risk groups, and discuss the complications.
