The eradication of tse-tse flies can prevent trypanosomiasis. Trypanosomiasis is a disease caused by a parasite that is transmitted by the bite of infected tsetse flies. These flies are found in sub-Saharan Africa and cause a lot of harm to both humans and livestock. By eradicating the tsetse fly, we can prevent the transmission of the parasite and the spread of the disease. However, the eradication of tsetse flies does not prevent other diseases like coccidiosis, aspergillosis, or tuberculosis which are caused by different pathogens and have different modes of transmission.
