Have there been other coronaviruses?
New and troubling viruses normally originate in animal hosts. Ebola and flu are different examples – extreme acute respiratory syndrome (Sars) and Middle Japanese respiratory syndrome (Mers) are each caused by coronaviruses that came from animals. In 2002, Sars spread virtually unchecked to 37 countries, inflicting world panic, infecting more than eight,000 folks and killing more than 750. Mers seems to be less easily passed from human to human, however 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 sick are reported to endure coughs, fever and breathing difficulties. In severe cases there could be organ failure. As this is viral pneumonia, antibiotics are of no use. The antiviral medicine we have towards flu is not going to work. If people are admitted to hospital, they may get assist for their lungs and other organs as well as fluids. Recovery will depend upon the strength of their immune system. A lot of those that have died had been already in poor health.
Is the virus being transmitted from one individual to another?
Human to human transmission has been confirmed by China’s nationwide health commission, and there have been human-to-human transmissions within the US and in Germany. As of 5 February, the demise toll has climbed to 490 in mainland China. There stays one additional fatality in Hong Kong and one within the Philippines. There are 24,505 confirmed cases world wide, with 24,292 being in mainland China. The mortality rate stands at 2.1%
Two members of one family have been confirmed to have the virus in the UK, after more than four hundred were tested and found negative. The Foreign Office has urged UK citizens to go away China in the event that they can.
The number of people to have contracted the virus might be far higher, as people with gentle symptoms may not have been detected. Modelling by World Health Organization (WHO) specialists at Imperial College London suggests there could possibly be as many as 100,000 cases, with uncertainty placing the margins between 30,000 and 200,000.
Why is this worse than normal influenza, and how apprehensive are the specialists?
We don’t but know how dangerous the new coronavirus is, and we won’t know until more data comes in. The mortality rate is round 2%. Nonetheless, this is likely to be an overestimate since many more individuals are prone to have been contaminated by the virus however not suffered severe enough symptoms to attend hospital, and so haven’t been counted. For comparability, seasonal flu typically has a mortality rate under 1% and is thought to cause about four hundred,000 deaths annually globally. Sars had a dying rate of more than 10%.
Another key unknown, of which scientists ought to get a clearer thought within the coming weeks, is how contagious the coronavirus is. An important distinction is that not like flu, there is no such thing as a vaccine for the new coronavirus, which means it’s more difficult for vulnerable members of the inhabitants – elderly people or those with existing respiratory or immune problems – to protect themselves. Hand-washing and avoiding other folks in case you really feel unwell are important. One smart step is to get the flu vaccine, which will reduce the burden on health providers if the outbreak turns right into a wider epidemic.

Is the outbreak a pandemic?
Health consultants are beginning to say it might turn out to be a pandemic, but proper now it falls in need of what the WHO would consider to be one. A pandemic, in WHO terms, is “the worldwide spread of a illness”. Coronavirus cases have been confirmed in about 25 nations outside China, but by no means in all 195 on the WHO’s list. It is also not spreading within these countries in the meanwhile, except in a very few cases. By far the bulk are travellers who picked up the virus in China.
