What are the symptoms of novel coronavirus?

Unconsciously, 2023 has arrived, and this year is a tortuous year. Due to the opening of the epidemic, everyone was not prepared, and the cold weather and the sudden drop of temperature led to a gradual increase in the number of patients in COVID-19. How should we deal with it?

To understand COVID-19, you don't have to ask three questions about COVID-19, COVID-19 and novel coronavirus. The main manifestations are fever, fatigue and dry cough, and a few patients are accompanied by symptoms of upper respiratory tract and digestive tract such as runny nose, stuffy nose and diarrhea. Most severe cases have dyspnea after 1 week, and severe cases rapidly progress to acute respiratory distress syndrome, septic shock, metabolic acidosis that is difficult to correct, bleeding and coagulation dysfunction and multiple organ failure. Because the specific reasons are unknown, it has brought a lot of panic to everyone. Even after being cured, some patients will leave irreversible sequelae for life, and even some patients will be reinfected. It is a great threat to us. Moreover, the virus is very cunning, and it is in the early stage of rapid change. The broad masses of the people should pay more attention, take protective measures and protect themselves.

From the current reports and studies, it can be determined that the main transmission routes in COVID-19 are direct transmission, aerosol transmission and contact transmission. Close contact with COVID-19 patients, close conversation, coughing and sneezing are all very likely to infect COVID-19. Secondly, being in a closed space with patients with COVID-19's disease is also very susceptible to infection. If you have come into contact with objects that have contact with COVID-19 virus, you may also be infected. Recently, there have also been news reports of environmental communication. Workers engaged in cold chain work were infected because COVID-19 was detected on the outer packaging of cold chain.

How can we cope with COVID-19 and keep healthy?

1. Avoid crowds. Since the discovery of the epidemic, most infected people have been infected because they have been in contact with infected people during meals. Therefore, they should refuse to eat and go to crowded places. As the year is approaching, try to reduce or avoid visiting relatives and friends, and spend the New Year at home to protect you, me and him.

2. Wear a mask. Never underestimate a small mask. It can stop more than 95% bacteria for you and protect your safety. The reason why the epidemic situation in China is so well controlled is not only the efforts of medical staff and volunteers, but also the people's high awareness of self-protection and wearing masks. It is best to choose a medical surgical mask. For ordinary people, n95 is actually unnecessary. Secondly, it is necessary to wear masks correctly, change masks in time, and dispose of discarded masks.

3. Do a good job in disinfection, wash your hands frequently, learn the seven-step washing method, keep in mind the formula of "inside, outside, clip, bow, big, stand and wrist", and disinfect with your hands quickly before and after meals, before and after handing things, before preparing food, after contacting animals, and after going out and going home. If you don't have the conditions to wash your hands, you should also use your hands quickly. In addition, you should always have disinfectant or 75% alcohol at home and wipe it regularly for disinfection. Especially after sneezing and coughing, be sure to wash your hands. Don't rub your eyes, touch your nose and mouth with dirty hands.

4. Pay close attention to your physical condition. In the face of the epidemic, we should pay close attention to our physical condition, whether there are symptoms such as fever, stuffy nose, runny nose, diarrhea, fatigue and dry cough. If you have these symptoms, have a fever for more than 3 days, or feel very uncomfortable, you should go to the hospital in time.

5. Raise awareness

In the face of epidemic situation, we should raise awareness of epidemic prevention and be cautious even if there are no symptoms, because some COVID-19 are asymptomatic, so don't take it lightly. If you have symptoms or come into contact with COVID-19 patients, don't take public transport or eat in crowded places, sleep separately from your family and use different tableware to prevent infection.

6. It is normal and understandable to feel anxious during the adjustment of mentality epidemic. At ordinary times, we should strengthen physical exercise, keep enough sleep and strengthen healthy eating.
