🌿 Overview
Leishmaniasis is found in the Near East, India, Asia, and parts of Latin America. It is transmitted by the bite of a tiny sand fly. Cutaneous (skin) forms cause open sores that may heal slowly over years. Visceral (internal) forms — kala azar — are more dangerous and affect internal organs.
Common signs
- Cutaneous: 2–8 weeks after bite, a swelling appears where the fly bit
- Swelling becomes an open sore, usually with pus
- Sores may heal in weeks to 2 years but can become bacterially infected
- Visceral: internal infection affecting liver, spleen, and lymph nodes (kala azar)
- Visceral symptoms: prolonged fever, severe weight loss, enlarged spleen and liver
🔎 Why it happens
Common causes and triggers — spotting yours is often the first step to relief.
- Leishmania parasites transmitted by sand fly bites
- Found in Near East, India, Asia, southern Mexico, and parts of Central/South America
- Multiple species causing cutaneous, mucosal, or visceral forms
- Rare in the U.S. but possible in travelers returning from endemic regions
✅ What to do
Gentle, practical steps you can take at home — start at the top.
- Clean skin sores with cooled boiled water
- Apply a hot, moist cloth to the sore for 10–15 minutes (not so hot as to burn)
- Repeat twice daily for 10 days — this often produces complete resolution of cutaneous disease
- If sore becomes red and painful (secondary bacterial infection), apply goldenseal, echinacea, or other antibiotic herbs
- Visceral form: see a physician — medical treatment is required
