If a patient eats uncooked pork, after a small amount or with relatively good immunity, there is not much problem after mild abdominal pain. However, if the immune system is relatively poor and a large amount of undercooked pork is consumed, there will be obvious digestive system symptoms such as abdominal pain, diarrhea, nausea, vomiting, or obvious upper gastrointestinal bleeding, or even periumbilical colic accompanied by mucopurulent stools and urgency. Severe patients may also develop a series of circulatory symptoms, such as chest tightness, shortness of breath, palpitations, precordial discomfort, peripheral weakness, etc. The most severe cases may also have varying degrees of infectiousness, such as fever, fever, and also neurological symptoms, such as dizziness and headache.
