It's all the same by nature. Both viral infections. Of course it was atypical pneumonia from 7 years ago, only the lungs were infected. Also the complications were not so much. Or the SARS of 17 years ago didn't develop as fast. And this year's new coronavirus. First of all it's contagious. Secondly the course of the disease is very erratic. Suddenly an inflammatory storm develops after infection. Resulting in multi-organ failure and multi-organ damage. So the essence is the same.

1, the incubation period of the new coronavirus is long, usually 14 days, and most infected people develop the disease in 7-10 days. Moreover, it can be transmitted during the incubation period.SARS virus is not contagious during the incubation period.

2, the new coronavirus, even if the onset of early symptoms are relatively mild, fever, sore throat, cough, fatigue is a common symptom, and the common cold symptoms are similar to the patient's attention can not be aroused, almost as usual activities, the spread of the virus. SARS patients, on the other hand, once the onset of the disease, almost all fever, 38 ℃ or more, systemic symptoms are also obvious, the patient wants to continue to wave can not. Moreover, only need to measure the body temperature can be very good to screen out the vast majority of suspected cases.

3. In China in 2020, there will be more high-speed railways, more airplanes, more international exchanges, more movement of people and more contacts between people, which will be more conducive to the global spread of the virus.

4. An outbreak at a transportation hub during the Chinese New Year is bound to spread the virus globally. Those who emphasize prevention and control can also control the imported epidemic very well, while countries and regions that do not emphasize prevention and control, the outbreak of the epidemic is only a matter of time.

5, China's response makes the new coronavirus look preventable and controllable, making it easy to be paralyzed.

The outbreak of the new coronavirus, I feel, can be described as a frog boiled in warm water, whereas the SARS virus pushed too hard, scaring people at the first sign of illness and affecting the continued spread of the virus.

As far as infectiousness goes, the new coronavirus is very good!!!! However, it also has a severe case rate of about 20%, and also usually incubates for 2 weeks and develops for 1 week before it becomes severe, the kind that requires respiratory support, or even a ventilator, ecmo, and a very long treatment time, which takes up healthcare resources tremendously. More severe cases can paralyze the healthcare system, and by then the mortality rate will be no less than that of SARS.

PS: Personally, I think the mortality rate of the new coronavirus is lower than SARS, not because the virus is weaker, but because medicine has been developing for 17 years. The virus outbreak first broke out in China, that's why the mortality rate seems so low. Italy is the size of Hubei province, and the Lombardy region is the equivalent of Wuhan, medical resources are already strained, nosocomial infections are appearing, retired healthcare workers as well as nurses who haven't graduated yet are going into battle, protective gear isn't enough yet, and the mortality rate is more than 6%, which is a serious situation, and I expect it to go up.

1. In November 2002, the first case of SARS occurred in Foshan, Guangdong Province. From November 2002 to August 5, 2003, 29 countries reported 8,422 clinically diagnosed cases and 916 deaths.

2, December 2019 New coronavirus pneumonia appeared in Wuhan, spreading very rapidly, with a cumulative total of more than 240,000 cases diagnosed globally as of now, with new cases being added daily.

3, the incubation period of SARS 1-16 days, commonly 3 to 5 days, has fever as the first symptom, there are stomach chills, body temperature over 38 degrees Celsius, the main mode of transmission of SARS for the proximity of droplet transmission or contact with the patient's respiratory secretions. The disease starts sharply, with fever as the first symptom, body temperature is usually higher than 38 degrees Celsius, occasional chills, can be accompanied by headache, joint pain, muscle pain, fatigue, diarrhea, often without upper respiratory tract katalog symptoms. There may be dry cough, little sputum, occasional blood sputum, chest tightness, and in severe cases, accelerated respiration, shortness of breath or obvious respiratory distress, causing severe pneumonia and respiratory failure.

4, the incubation period of the new coronavirus pneumonia for 1 ~ 14 days or even longer, the initial symptoms are mainly manifested as fever, dry cough, sore throat, some patients will have runny nose, sneezing and other symptoms. With the prolongation of the disease, some patients will have chest tightness, dyspnea and other symptoms. Therefore, patients with new coronary pneumonia need timely treatment, which can control the progress of the disease and reduce the incidence of severe and critical illnesses.

Research data show that the new coronavirus and the SARS virus are completely different viruses. Although the new coronavirus has special features, it is less lethal and less contagious than the SARS virus. The severity of the new coronavirus is not as serious as that of the SARS virus at the time of infection, and although no effective therapeutic drugs have yet been developed, it is possible to control the disease.

There are similarities and differences between the SARS of 17 years ago and the present situation, which began 17 years ago in Shenzhen and gradually expanded to Guangzuo and north to Beijing. There is a certain degree of contagiousness, but the outbreak is not as big as this year's outbreak, and it is a worldwide outbreak, the intensity of which is extremely rare.

On the basis of our experience in treating SARS 17 years ago, we utilized a lot of Chinese medicine to quickly extinguish the coronavirus cold in a timely manner, and it only took about 14 to 20 days from the outbreak to the remission period. We have 2 kinds of medicine in China, and even if a localized rebound occurs, it is not scary, and coronavirus colds will not ravage endlessly ......!

The pneumonia outbreak in the central Chinese city of Wuhan has been linked to a new coronavirus. Coronaviruses belong to a large family of viruses that produce symptoms ranging from mild cases such as a cold to severe cases including Severe Acute Respiratory Syndrome, or SARS. Because some of the patients in this outbreak worked or consumed seafood at markets where live animals and game were sold, there is concern that the new coronavirus may be of animal origin, as was the case in the previous outbreak of SARS, which killed nearly 800 people 17 years ago. The SARS outbreak 17 years ago killed nearly 800 people. But health officials say there are significant differences between the two.

The incubation period of SARS is short and the symptoms can be quickly realized and easily detected, while the incubation period of the new crown is long and the symptoms are not obvious and not easy to be detected, therefore it is very contagious. Compared to SARS and the new crown SARS mortality rate is high.

Coronaviruses and SARS The World Health Organization has announced the official identification of a variant of the coronavirus as the pathogen that causes atypical pneumonia. Scientists say the variant coronavirus is related to the influenza virus, but it is so unique that it has never been found in humans before, and scientists have named it the 'SARS virus' (SARS is the English acronym for the scientific name of 'atypical pneumonia'). According to Hong Kong health officials, SARS is usually caused by viruses, such as influenza virus, adenovirus and other respiratory viruses. SARS may also be caused by organisms. Coronavirus infections are very common worldwide, and coronavirus antibodies are prevalent in the population and are higher in adults than in children. Countries report different rates of antibody positivity in their populations, with previous rates of coronavirus antibody positivity in our population ranging from 30% to 60%, and in the former Soviet Union ranging from 53% to 97%. New virus similar to SARS Britain confirmed a case of infection with a new coronavirus, the patient developed acute respiratory syndrome and accompanied by renal failure, the symptoms of the case are similar to SARS (infectious atypical pneumonia). The UK's Health Protection Agency said the virus is a coronavirus in the same family as the SARS virus, but tests have shown that it is not the SARS virus. The virus infected a 49-year-old Qatari man who returned to Qatar from a trip to Saudi Arabia on September 3 with fever and breathing difficulties. 11, the patient from Qatar to the United Kingdom to receive treatment in an emergency, and has developed kidney failure. 23, the patient was confirmed to be infected with a new type of coronavirus. The UK Health Protection Agency (HPA) has reported the incident to the World Health Organization (WHO). WHO confirmed the case through a Global Outbreak Alert and Response System (GOARS) announcement. The case follows the death of a 60-year-old Saudi man who was infected with the coronavirus. British scientists compared the sequences of the virus isolated from the Saudi man's postmortem lung tissue and the Qatari patient's viral sequences, which were 99.5 percent similar. Both men presented with acute respiratory infections accompanied by acute kidney failure. Only these two cases have been diagnosed globally. John Watson, head of the respiratory diseases unit at the UK's Health Protection Agency, said there was no evidence yet that the virus could be transmitted from person to person. The patient is currently under close supervision, British health care workers are carrying out further observation of the patient, and the relevant departments have also raised the vigilance of epidemic prevention. According to the World Health Organization, there are many types of coronaviruses, including those that cause the common cold and those that cause SARS. The discovery is a new type of coronavirus, and the WHO is still obtaining further information to confirm the public health impact of these two cases.

The SARS of '03 had a short incubation period, a high cure rate, and was not as contagious as the current coronavirus, which is airborne, while the coronavirus spreads mainly by droplets. No matter what kind of virus, human medicine will overcome it.
