Overview

• The WHO’s new 125-page guidelines provide standardized, evidence-based treatment protocols for dengue, chikungunya, Zika and yellow fever across all care settings.
• WHO data show more than 5.6 billion people face infection risks as Aedes mosquitoes spread into temperate regions driven by climate change, urbanization and travel.
• Scarce laboratory testing in many affected areas complicates accurate diagnosis of clinically similar arboviral infections and heightens the risk of mistreatment.
• French authorities confirmed Europe’s first locally acquired chikungunya infection near Strasbourg, signaling that transmission is no longer confined to travelers.
• The Robert Koch Institute warns of imminent local outbreaks in Germany, and STIKO has issued its first chikungunya vaccine recommendation for travelers and other high-risk groups.
