Think you can spot this sneaky culprit behind post-flood fevers? Introducing Leptospira, the spiral-shaped bacteria that loves puddles, mud, and anything contaminated after a heavy rain. It causes Leptospirosis, a disease that can infect both humans and animals—especially common during the rainy season.
MicrobeDex Entry #001 – Leptospira
Found in contaminated water and soil, Leptospira affects about a million people worldwide each year, with higher risk in areas with poor drainage or frequent flooding.
Habitat / Ability – How It Spreads
This microbe spreads through the urine of infected animals and can survive in damp environments for weeks. It enters through open wounds, or even through the eyes, nose, or mouth—making floodwater a risky battlefield.
Move List / Attack Effects – Signs and Symptoms
Leptospira’s attacks may appear 2–30 days after exposure:
• Fever, headache, chills, body pain
• Nausea, vomiting, diarrhea
• Yellowish skin and eyes (jaundice), red eyes, or rash
Not everyone infected shows symptoms, so stay alert after exposure.
Trainer Defense Strategy – Prevention Tips
• Avoid wading or swimming in floodwater.
• Wash with antibacterial soap immediately after contact.
• Wear protective boots, gloves, or plastic coverings when needed.
• Keep surroundings clean and drains unclogged.
• Ensure drinking and cooking water are safe.
• Dispose of trash properly to prevent rodent breeding.
Consult Nurse Joy / Pokémon Center Visit – Treatment and When to See a Doctor
If you’ve had contact with floodwater, a doctor may prescribe doxycycline (200 mg once within 24–48 hours) as prophylaxis. Always consult a licensed healthcare provider first. Doxycycline is not recommended for pregnant women or children under 8—ask for medical alternatives. See a doctor if you experience fever, jaundice, red eyes, or if you’ve waded in floodwater with open wounds. Severe cases may need Penicillin G treatment in a hospital.
Trainer Tip / Victory Screen
Leptospirosis is preventable and treatable.
Stay informed, stay clean, and don’t let Leptospira claim victory this rainy season.
