Winter and spring are the high season for respiratory infectious diseases, and the frequent movement of people increases the risk of spreading infectious diseases. For the prevention of novel coronavirus pneumonia, wild animals should be avoided, especially not to eat already diseased animals and their meat products; frozen meat should be purchased from regular channels; poultry, meat, eggs and milk should be fully cooked when consumed; when handling raw and fresh products, utensils should be separated from raw and cooked, and washed in time to avoid cross-contamination. If you have fever, cough and other uncomfortable symptoms, you should promptly consult the fever clinic to clarify the specific cause of the disease and carry out targeted treatment.
