Which of the following is an incorrect match between symptoms and disease?

The match between myalgias and trichuriasis is incorrect because trichuriasis, caused by the parasitic worm Trichuris trichiura, primarily results in gastrointestinal symptoms rather than systemic symptoms like muscle pain. In cases of trichuriasis, patients often experience symptoms such as abdominal pain, diarrhea, and in severe cases, anemia, especially in children with heavy infestations. Myalgias, which refer to muscle pain, are not commonly associated with this disease.

In contrast, the other matches are accurate in terms of the symptoms they describe. Dysentery is indeed a symptom of amebiasis, which is an intestinal infection caused by the Entamoeba histolytica parasite, often leading to severe diarrhea with blood and mucus. Malabsorption syndrome can occur in giardiasis, resulting from the Giardia lamblia parasite affecting the intestinal lining, leading to nutrient absorption issues. Lastly, chronic Chagas disease can result in various complications, including cardiac problems due to the parasitic infection caused by Trypanosoma cruzi. Thus, considering the nature of the symptoms and their typical associations with the respective diseases helps clarify why myalgias do not align with trichuriasis.
