Which description best reflects Trichinellosis after consumption of undercooked meat?

• A. Diarrhea, nausea, vomiting, fatigue, fever, abdominal discomfort
• B. Severe headache with neck stiffness
• C. Jaundice and RUQ pain
• D. Purpuric rash

Answer: (A)

When Trichinellosis is contracted from undercooked meat, the early symptoms reflect ingestion of the larvae and initial gastrointestinal involvement. The disease often begins with diarrhea, nausea, vomiting, abdominal discomfort, along with fever and fatigue as the parasites mature in the gut and begin to disseminate. This GI plus systemic picture is the best match for Trichinellosis right after eating contaminated meat. The other descriptions point to different illnesses—headache with neck stiffness suggests meningitis; jaundice with right upper quadrant pain suggests hepatitis or biliary disease; a purpuric rash points to vasculitis or meningococcemia—so they don’t fit the typical early presentation of trichinellosis.
