According to the current epidemiological investigation, the main symptoms of novel coronavirus are fever, fatigue and dry cough, and a few patients are accompanied by symptoms such as nasal congestion, runny nose and diarrhea.
The incubation period of the disease is 1- 14 days, mostly 3-7 days. Mild patients only show low fever and mild fatigue. And no pneumonia such as cough and dry cough.
Severe patients often have dyspnea and/or hypoxemia one week after onset, and severe cases quickly progress to acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, and bleeding and coagulation disorders. Severe and critical patients may have moderate or low fever or even no obvious fever during the course of the disease.
In addition to the above symptoms, the disease can also be atypical, such as digestive system symptoms as the main performance, such as mild loss of appetite, fatigue, poor spirit, nausea and vomiting, diarrhea and so on. Headache of nervous system is the first symptom; The first manifestation is eye symptoms, such as conjunctival congestion and increased eye secretions. Or only slight limb or back muscle pain. At the same time, the symptoms of the disease are similar to pneumonia caused by influenza virus, parainfluenza virus, adenovirus, respiratory syncytial virus, rhinovirus and other inhibitory viruses, so it is necessary to pay attention to differentiation.
2. How to write a composition about COVID-19?
Recently, the new pneumonia epidemic in Wuhan has attracted national attention, and even several people died of infection.
At this time, people hope that the country will find a new treatment for pneumonia as soon as possible. The new pneumonia is a coronavirus. In addition to this virus named 20 19-ncov, there are six other coronaviruses, the most familiar of which is SARS coronavirus.
I believe many people still can't forget the disaster 17 years ago, which lasted for eight months and 9 19 people were killed. There was a panic all over the country, and the town was isolated overnight. Banlangen is completely out of stock, and disinfection products such as white vinegar and garlic are growing rapidly, even as high as several thousand yuan ... People have to use this method to comfort themselves. The new pneumonia epidemic in Wuhan this time is not so easy to cure. As one of the most developed cities in China, Wuhan, a thoroughfare of nine provinces, was easily taken to other cities during its stay in Spring Festival travel rush, and this coronavirus has been confirmed as "human-to-human transmission".
By 24: 00 on October 20th, novel coronavirus 198 people had been diagnosed in Wuhan, and there were patients in other cities and countries. The situation is worrying. However, I don't think people are as scared as they were when SARS happened. This is probably because the country has carried out real-time live broadcast of the new pneumonia epidemic nationwide, making people less easily intimidated by rumors.
This was not the case during the "SARS" period. At that time, all localities tried their best to block information to avoid "losing face" internationally ... This time, * * * learned a lesson, released news in time, and worked hard to study countermeasures. This difficult period will definitely pass.
I believe in the country, and history will definitely not repeat itself. We will take history as a mirror to control the epidemic as soon as possible and prevent the recurrence of past disasters.

The longest incubation period in novel coronavirus is about 14 days.
Experts interpret the incubation period of novel coronavirus infection: the average incubation period is about 7 days, and there have been patients with incubation period as long as 24 days, which should be an example.
"At present, according to the existing cases, the average incubation period of pneumonia infection in novel coronavirus is about 7 days, which can be as short as 2 to 3 days and as long as 10 to 14 days. According to the observation of existing cases, the initial symptoms of pneumonia in novel coronavirus are accompanied by fever, with low fever or even high fever. In addition, patients will have symptoms of dry cough, with less cough, expectoration and even pus. After three to five days, these patients will gradually develop symptoms of shortness of breath or chest tightness, especially after activities. Some patients have severe symptoms and may have respiratory failure or even shock. If patients have low fever, high fever or respiratory symptoms, they should seek medical advice promptly, especially if some patients have been in contact with people with similar symptoms or other hospitalized patients, and this symptom occurred without protection, they should seek medical advice as soon as possible.
