What is the coronavirus and how worried should we be? theguardian.com
What is the virus causing illness in Wuhan?
It is a novel coronavirus – that is to say, a member of the coronavirus family that has never been encountered before. Like other coronaviruses, it has come from animals. Many of those infected either worked or frequently shopped in the Huanan seafood wholesale market in the centre of the Chinese city, which also sold live and newly slaughtered animals. New and troubling viruses usually originate in animal hosts. Ebola and flu are examples.
What other coronaviruses have there been?
Severe acute respiratory syndrome (Sars) and Middle Eastern respiratory syndrome (Mers) are both caused by coronaviruses that came from animals. Although Mers is believed to be transmitted to humans from dromedaries, the original hosts for both coronaviruses were probably bats. There are suspicions now that the new coronavirus may have originated in bats or snakes, and possibly then was transmitted to humans via an intermediary species. In 2002 Sars spread virtually unchecked to 37 countries, causing global panic, infecting more than 8,000 people and killing more than 750. Mers appears to be less easily passed from human to human, but has greater lethality, killing 35% of about 2,500 people who have been infected.
What are the symptoms caused by the Wuhan coronavirus?
The virus causes pneumonia. Those who have fallen ill are reported to suffer coughs, fever and breathing difficulties. In severe cases there can be organ failure. As this is viral pneumonia, antibiotics are of no use. The antiviral drugs we have against flu will not work. If people are admitted to hospital, they may get support for their lungs and other organs as well as fluids. Recovery will depend on the strength of their immune system. Many of those who have died are known to have been already in poor health.
Is the virus being transmitted from one person to another?
Human to human transmission has been confirmed by China’s national health commission. As of 24 January the Chinese authorities had acknowledged more than 1,000 cases and 41 deaths. In the past week, the number of confirmed infections has more than tripled and cases have been found in 13 provinces, as well as the municipalities Beijing, Shanghai, Chongqing and Tianjin. The virus has also been confirmed outside China, in Hong Kong, Macau, Japan, Nepal, Singapore, South Korea, Taiwan, Thailand, the US, and Vietnam. There have not been any confirmed cases in the UK at present, with the 14 people tested for the virus all proving negative. The actual number to have contracted the virus could be far higher as people with mild symptoms may not have been detected. Modelling by WHO experts at Imperial College London suggests there could be 4,000 cases, with uncertainty putting the margins between 1,000 and 9,700.
How worried are the experts?
There were fears that the coronavirus might spread more widely during the week-long lunar new year holidays, which start on 24 January, when millions of Chinese travel home to celebrate, but the festivities have largely been cancelled and Wuhan and other Chinese cities are in lockdown. At the moment, it appears that people in poor health are at greatest risk, as is always the case with flu. A key concern is the range of severity of symptoms – some people appear to suffer only mild illness while others are becoming severely ill. This makes it more difficult to establish the true numbers infected and the extent of transmission between people. But the authorities will be keen to stop the spread and will be anxious that the virus could become more potent than it so far appears.
At what point should you go to the doctor if you have a cough, say?
Unless you have recently travelled to China or been in contact with someone infected with the virus, then you should treat any cough or cold symptoms as normal. The NHS advises that there is generally no need to visit a doctor for a cough unless it is persistent or you are having other symptoms such as chest pain, difficulty breathing or you feel very unwell.

Why is this any worse than normal influenza?
We don’t yet know how dangerous the new coronavirus is – and we won’t know until more data comes in. Twenty-six deaths out of 800 reported cases would mean a 3% mortality rate. However, this is likely to be a overestimate since there may be a far larger pool of people who have been infected by the virus but who have not suffered severe enough symptoms to attend hospital and so have not been counted in the data. For comparison, seasonal flu typically has a mortality rate below 1% and is thought to cause about 400,000 deaths each year globally. Another key unknown, of which scientists should get a clearer idea in the coming weeks, is how contagious the coronavirus is. A crucial difference is that unlike flu, there is no vaccine for the new coronavirus, which means it is more difficult for vulnerable members of the population – elderly people or those with existing respiratory or immune problems – to protect themselves. One sensible step to get the flu vaccine, which will reduce the burden on health services if the outbreak turns into a wider epidemic.
醫生必須救病人嗎?
Should doctors risk their own lives to treat victims of epidemics?

Apart from treating epidemics, doctors put patient needs before their own routinely and encounter health risks, big and small, as a result. Most do this because they care deeply about the people they are assisting, not because of a sense of obligation.
In the case of epidemics, standard procedures for handling infectious cases have been designed to protect doctors and other healthcare practitioners, not only for the sake of their health but also as a means of preventing the spread of infection.
Should doctors risk their own lives to treat victims of epidemics? In general, no. If it increases the chance of spreading infection, absolutely not.
Unlike many unrealistic answers by people not having worked in the field, it's our first duty to keep ourselves save, because getting sick, even dying because of catching a disease while treating a patient is totally useless, infantile heroics, no patient benefits from this, many patients will receive less care because of the extra patient (the doc that fell ill) taking up a hospital bed that is scarce and there being one less person to treat the patients.
So docs must jealously guard their own safety while treating infectious patients, not catching the disease, like those health care peopl...
Well the point of doctors is to help others. That's the goal for them, because they enjoy it. Of course they should! Not without a doubt. Depending on the doctor, they are willing to risk their lives looking for an answer or a cure. Kind of relate to a reporter, they do anything to get the news and tell everyone because it's their job, it's something they love to do. They want to get the word out. Or even a scientists! So now for doctors, they want to help others, so no one else will have to suffer the pain. I believe so, if not, there's no reason for doctors to help anyone in need.
According to me, yes the doctors should risk their lives for treating the victims of epidemics because they are “DOCTORS”. And the most important task of being a doctor is to risk their own lives and save the victims, not only of epidemics but many other communicable diseases also
