Health Warning After Flooding in Hawaii

Following the recent flooding caused by the “Kona low” storm, the Hawaii Department of Health and Hawaiian Humane Society are cautioning residents and recovery workers about the potential dangers of leptospirosis.

Leptospirosis is a bacterial infection that can affect both humans and pets. The bacteria, Leptospira, is typically found in the urine of infected animals such as rats, mice, mongooses, and domestic pets. It spreads through contact with contaminated water or soil.

According to health officials, Hawaii has one of the highest rates of leptospirosis in the U.S., thanks to its humid climate. Flooding can exacerbate the situation by dispersing contaminated substances widely.

Symptoms in humans may surface five to 14 days after exposure. They include fever, chills, headaches, muscle aches, and even jaundice. However, symptoms can also take longer to present, ranging from two to 30 days. For pets, indicators can vary from fever and lethargy to increased thirst and vomiting.

Dr. Lisa Labrecque, Chief Veterinarian at the Hawaiian Humane Society, pointed out that the risk of leptospirosis often rises after significant rainfall. “Many families were simply trying to cope during this storm, and their pets faced those same conditions,” she said. She emphasized the importance of seeking veterinary care if pets show any signs of illness, as early antibiotic treatment can be crucial.

Veterinarians are encouraging pet owners to discuss the leptospirosis vaccine with their vets, especially following recent flooding. Dr. Ariella Barry, from the DOH, added that pets can serve as early warning signs for leptospirosis in the community. If a pet falls ill, it might be an indication of possible exposure for their human companions as well. Prompt medical attention for both pets and people can lead to better outcomes for everyone involved.
