Deadly Bacteria Lurks in Hawaii Floodwaters

Health authorities in Hawaii are issuing urgent warnings regarding leptospirosis, a dangerous bacteria found in the aftermath of the recent 'Kona low' storms. These storms inundated the state with trillions of gallons of rain, creating conditions ripe for the spread of Leptospira bacteria, which contaminates soil and water.

The bacteria, originating from infected animal urine, can persist for weeks or months. During severe flooding, it infiltrates the body through cuts, the nose, mouth, or eyes, potentially causing severe illness. Symptoms include respiratory distress, internal bleeding, and organ failure.

Hawaii already experiences high rates of leptospirosis due to its climate, and these floods have significantly amplified exposure risks. While rare, human-to-human transmission can occur in crowded shelters. Severe cases, particularly those involving pulmonary hemorrhage, have a mortality rate as high as 50 percent.

Veterinarians and health officials urge prompt medical attention for anyone, including pets, exhibiting symptoms. Antibiotics are effective for treatment in both humans and animals, though no human vaccine is available. Pets can serve as early indicators of circulating bacteria in the community.
