African Trypanosomiasis

• It is also known as African sleeping sickness
• Its pathogens are transmitted by the bite of tsetse fly (Glossina palpalis and G. morsitans).
• The site where fly bites become very painful and a nodule called trypanosoma chancre generally develops after 48 hours at the site of the bite.
• Lymph nodes swell, the parasite enters the cerebrospinal fluid and then migrates to the brain.
• The patient becomes lethargic and finally falls unconscious.
