Clinical symptoms of corona virus:
First of all, we must know that the new coronavirus may originate from wild animals, or a certain kind of chrysanthemum-headed bat, which can be transmitted through contact with objects, air droplets, and feces. The incubation period is 1-14 days, mostly 3-7 days, with fever, fatigue, and dry cough as the main manifestations. However, there are also a few cases with digestive system symptoms as the first manifestation: such as mild anorexia, fatigue, poor spirits, nausea, vomiting, diarrhea, etc.; or cardiovascular and cerebrovascular symptoms as the first manifestation: such as headache, palpitation, chest tightness, etc.; or ophthalmology Symptoms are the first manifestations: such as conjunctivitis. However, fever is still the main symptom, and we must attach great importance to it. Secondly, we must also pay attention to the hidden source of infection, that is, the patient has been infected but has not yet shown relevant symptoms. During this period, he can also infect other people.
Clinical diagnosis and classification
Clinical manifestations
1. Fever and/or respiratory symptoms (stuffy nose, runny nose, sore throat, etc.);
2. There are imaging features of pneumonia (in the early stage, there are multiple small patchy shadows and interstitial changes, which are obvious outside the lungs. );
3. The white blood cell count is normal or decreased in the early stage of the disease, or the lymphatic count is decreased.
Respiratory tract specimens or blood specimens are positive for nucleic acid of new coronavirus by real-time fluorescent RT-PCR; viral gene sequencing is highly homologous to known new coronaviruses.
