Extra than 156,700 cases have been confirmed since the outbreak started, and the death toll has exceeded 5,800. The vast majority of cases are in China, but the virus has spread to more than 100 other countries.
According to data from the Chinese authorities, around 80 per cent of cases of the disease are gentle, but 20 per cent require hospitalisation.
Is coronavirus in the UK?
1,140 folks in the UK have tested clear for the virus so far.
An aged person with underlying health disorders became the primary person in Britain to die having been diagnosed with the disease, Royal Berkshire NHS Have faith confirmed on March 5. 20 more folks have now died.
Police have been handed unprecedented powers to pressure those at chance of coronavirus into quarantine amid fears that two GPs may have passed the virus on to patients.
The new measures have been put in place with immediate design as Matt Hancock, the Health Secretary, warned that the spread of the virus is a “severe and imminent threat” to the British public.
Is there a remedy for the coronavirus?
There’s rarely always any particular treatment, although doctors are trialling existing medicine for viruses such as Ebola and HIV. Early results appear promising but, unless stout clinical trials have been concluded, doctors cannot be certain that the medicine are effective.
Work to obtain a vaccine is accelerating, but this work has been complicated by the virus mutating into a 2nd strain.

Who started the coronavirus?
Various crazy conspiracy theories have been circulating that the virus somehow escaped from a Chinese lab, either by accident or design. On the alternative hand, right here’s categorically false and scientists studying its genetic code have linked it to bats. It probably then jumped to another animal, which passed it on to humans.
The variety of diseases crossing from animals to humans is growing, and teams of virus hunters are tracking them down.
The place is the disease now?
As smartly as being reported in China, the disease is now in more than 80 countries around the arena, including popular south-east Asian holiday destinations such as Thailand, Vietnam, Singapore and Malaysia.

It’s unclear why the death rate is increased in Wuhan, but it indubitably may be because the health companies there have been overwhelmed by patients. Men are more probably to have a severe manufacture of the disease, as are folks with underlying stipulations such as diabetes or high blood stress.
How does this coronavirus compare to past respiratory epidemics?
The 1918 Spanish Influenza – or the H1N1 virus – remains the most devastating flu pandemic in fashionable history. The disease swept around the globe and is estimated to have caused between 50 and 100 million deaths.

Other major influenza outbreaks include Asian flu in 1957, which led to roughly two million deaths, and Hong Kong flu, which killed 1,000,000 folks 11 years later.
But coronavirus outbreaks have so far been far smaller. Sars eventually spread to 27 countries in total, infecting around 8,000 folks and killing 700.
Is there anything I ought to be doing to prepare?
