Question

BlackTom AI · Accepted Answer

When tackling a question about American Trypanosomiasis (Chagas disease), it helps to recall the clinical features and transmission details associated with the infection.
Option a: 'Presented with disrupted sleep cycle' is not a defining or classic feature of acute or chronic Chagas disease. Sleep disturbances are not typically used as a hallmark diagnostic clue for American Trypanosomiasis, so this statement is not supported by standard clinical descriptions.
Option b: 'Chagoma is detected during the acute stage of infection' is correct. A chagoma (the localized inflammatory skin lesion at the site of Trypanosoma cruzi entry, such as the inoculation site after a triatomine bug bite) often appears during the acute phase and is a characteristic early sign in some patients. This aligns with the typical course: the acute stage may present with romanas signs like chagoma or fever, malaise, and lymphadenopathy.
Option c: 'Transmitted by Tze Tze fly' is inaccurate. The vector for American Trypanosomiasis is the triatomine bug (often called the kissing bug), not a Tze Tze fly. Confusing vectors between diseases leads to this incorrect choice.
Option d: 'Hepatomegaly occurs at the later stage of the infection' is misleading. While organomegaly can occur in Chronic Chagas disease due to cardiomyopathy and gastrointestinal involvement, hepatomegaly is not a defining or consistently late-appearing feature used to describe the progression of classic American Trypanosomiasis; the disease is more characteristically associated with cardiac and GI tract complications rather than prominent hepatomegaly as a hallmark.
In summary, among the options, only the statement about chagoma appearing during the acute stage correctly reflects a recognized acute-stage manifestation of American Trypanosomiasis, while the others misstate clinical features or transmission details.
