- Tap water is potable, but hiking or swimming in freshwater or muddy areas can expose travellers to **leptospirosis**. Avoid swallowing untreated water, cover cuts, and seek medical care for fever, severe headache, muscle aches, or vomiting after possible exposure.

## Recent News

- **October 10:** Flood advisories covered northern and southern Guam, with an islandwide flood watch continuing through late night. Heavy rain had already produced 2 to 4 inches, and saturated conditions increased the risk of flash flooding on roads, in underpasses, streams, and low-lying areas.

- **October 7:** The U.S. Supreme Court heard a challenge to the Air Force’s continued detonation of unexploded munitions at Tarague Beach. Travellers should follow access restrictions and avoid military areas or unexploded-ordnance sites; the case concerns possible environmental and water-resource impacts, not a general islandwide safety alert.

- **October 7:** A major disaster declaration was approved for damage caused by Super Typhoon Bavi in July. Recovery and repairs may still affect some public infrastructure and services, although the declaration primarily provides assistance to residents and government facilities.
