Important: How to Protect Against Leptospirosis After Flooding
Why It Matters
After hurricanes or heavy rains, contaminated water can become a breeding ground for leptospirosis, a bacterial illness spread through the urine of infected animals. Floodwater, soil, and even food or drinking water can be tainted, posing a serious health risk if you come into contact with it.
How It Spreads
You can get infected by:
• Touching contaminated floodwater or soil
• Coming into contact with infected animal urine or body fluids
• Consuming contaminated food or drinking water 
Stay Safe: Prevention Tips
• Don’t rely on floodwater: Avoid wading in, bathing in, or drinking from floodwaters or potentially tainted natural sources.
• Use safe water only: Boil or chemically treat water before using it for drinking or cooking.
• Cover wounds: Apply waterproof bandages or coverings to any cuts, abrasions, or scratches.
• Wear protective gear: When near floodwater or damp soil, wear waterproof clothing, gloves, and sturdy shoes or boots.
• Control rodents: Secure food, trash, and water in closed containers and consider non-chemical traps to discourage rodents in your area.
Symptoms to Watch For
Symptoms typically appear between 2 and 30 days after exposure (most often within 5–14 days) . Early signs may include:
• Fever or chills
• Headache or muscle aches
• Nausea, vomiting, abdominal pain, or diarrhea
• Red eyes, rash, or jaundice (yellowing of skin/eyes)
See a doctor immediately if you notice any of these symptoms following exposure.
Treatment Essentials
• Prompt medical attention is vital. If leptospirosis is suspected, early antibiotic treatment, such as doxycycline or penicillin, can significantly reduce the risk of severe illness.
• Severe cases may require hospitalization or intravenous antibiotics; early treatment helps prevent complications .
