Properly prepared cooked pork products are safe to consume. Pork is cooked to an internal temperature of 71 degrees. This kills bacteria and viruses. The incubation period for influenza A (H1N1) is usually 1-7 days, with a high incubation period of 1-4 days. The main clinical symptoms include fever, runny nose, nasal congestion, sore throat, cough, headache, myalgia, malaise, vomiting, diarrhea, pneumonia and other morbidities may occur. In a small number of patients, the disease progresses rapidly and respiratory failure occurs. In clinical practice, patients are classified into two categories: suspected cases and confirmed cases. All patients need to be isolated in the hospital. They are also treated with specific medications. Their close contacts should be placed under medical observation and, if necessary, given specific medications. In case of fever, runny nose, sore throat, etc., go to the hospital fever clinic promptly and follow the arrangement of the medical staff.
