Swollen lymph nodes

When bitten by a fly, the virus gradually attacks the immune system. African Trypanosomiasis disease appears suddenly, occurring 1 to 10 days (usually 2 to 4 days) after exposure, with headache, and fever. Within 24 to 48 hours, nodular lesions will appear in the exposed area (fingers, arms, eyes, roof of the mouth), except for glandular or typhoid-like forms. The papule quickly becomes pustular and ulcerated, the mouth clears to a small, thin, colourless number.

The sores are usually solitary but may be multiple in the mouth or eyes. Usually, only one eye is affected. Regional lymph nodes swell and may fester and burst. A typhoid-like state usually develops by day 5 and the patient may develop atypical pneumonia, sometimes with delirium. After a fly sting, continuous saline dressings are beneficial for major skin lesions and may reduce the severity of lymphadenitis. Patients need to go to the hospital for timely treatment by doctors.
