Rapid Chikungunya Spread And Risk
- Chikungunya is causing a fast-rising outbreak in Guangdong, China, and has spread to many countries in 2025.
- The virus spreads via Aedes mosquitoes and travels easily with global travel, raising concern for the U.S.
Protect Yourself From Chikungunya
- Use insect repellents and protective clothing to lower your risk of chikungunya infection when traveling to affected areas.
- Vaccination is available: two FDA-approved vaccines reduce infection risk and are effective preventive tools.
Gloffs Grow As Glaciers Melt Faster
- Glacial lake outburst floods (gloffs) occur when meltwater breaches natural ice or moraine dams, and have become more frequent as glaciers melt faster.
- Suicide Basin's annual outbursts have intensified since 2023, raising flood peaks and local monitoring needs.
