The number of people infected in the UK continues to rise. More than 270 people have tested positive for Covid-19.
Here is all you need to know today:
– What is the scale of the problem?
In the UK, 273 people have tested positive for Covid-19 as of 9am on Sunday, up from 206 cases reported at the 7am on Saturday. Three people, all with underlying health conditions, have died after testing positive for the virus.
Globally, the number of coronavirus cases has passed 100,000, with more than 3,500 deaths. Most of them have been in China.
– How bad could it get?
Half of all coronavirus cases in the UK are most likely to occur in just a three-week period, with 95% of them over a nine-week period, according to England’s chief medical officer Professor Chris Whitty.
Prof Whitty said he had a “reasonably high degree of confidence” that 1% is at the “upper limit” of the mortality rate for the virus, although Wuhan in China, which has a weaker health system, had seen an 8% to 9% mortality rate for those aged 80 and over.
– What is the Government doing now?
The UK response is in the delay stage, which means measures can be ramped up to delay its spread, with possibilities including school closures, encouraging greater home working, and reducing the number of large-scale gatherings.
However, officials say closing schools would possibly only have a “marginal effect”, adding that children do not appear to be as badly affected by Covid-19 as other groups.
– What is the UK Government recommending people do on returning from infected regions?
People returning from Hubei province in China, Iran, locked-down areas in northern Italy and special care zones in South Korea in the past 14 days should immediately self-isolate at home and call NHS 111.
Those returning from a number of other areas, including the rest of China and Korea, Japan, Hong Kong and Singapore, should self-isolate if they develop symptoms of a cough or fever or shortness of breath.
It also said those returning from Vietnam, Cambodia, Laos, Thailand, Burma and other parts of Italy should self-isolate if they show symptoms, even if they are mild.
– How do I self-isolate if I am asked to?
If you are told to self-isolate, you should stay at home and not go to work, school or public places.
You should also not use public transport such as trains or buses, or take taxis.
You should try to avoid close contact with family members and do not have visitors to your home.
However, it is fine for friends, family or delivery drivers to drop off food.
– What about a vaccine?
Prime Minister Boris Johnson visited a Bedfordshire laboratory on Friday as the Government pledged an extra £46 million for research into coronavirus vaccines and rapid diagnostic tests. He hopes a vaccine can be developed within the year.
Vaccines have been developed and researchers are starting to test them on animals, but tests can take months to see if any potential vaccine can be used on humans and there will then have to be trials on humans.
The World Health Organisation (WHO) has convened a group of experts to fast-track promising tests, drugs and vaccines.
The UK Government is also putting £40 million into trying to find a vaccine and is also aiming to improve treatments for patients with the disease.
– What is a coronavirus?
Coronaviruses are a large family of viruses that cause illnesses ranging from the common cold to more severe diseases such as severe acute respiratory syndrome (Sars).
The strain that has recently emerged is a new strain that had not been previously identified in humans. The respiratory disease it causes has been named Covid-19 by the WHO.
– Where did it come from?
Coronaviruses are zoonotic, meaning they are transmitted between animals and people, the WHO says.
The first cases identified were among people connected to the Huanan Seafood Wholesale Market in Wuhan, China.
– How is it spread?
Experts believe the virus is spread in cough and sneeze droplets.
The virus can survive on surfaces for several hours, but it is unclear exactly how long for.
Government scientists say a small proportion of people will pass on the virus while having no symptoms themselves.
– What steps can I take to protect myself?
Wash your hands with soap and hot water more often. Do this for at least 20 seconds each time.
The NHS says people should also wash their hands when they get home or arrive at work.
Hand sanitiser can be used if soap is not available.
Anyone with coughs and sneezes should catch them in a tissue, which is then put in a bin. Wash your hands afterwards.
People should also avoid close contact with people who are unwell, and avoid touching the eyes, nose or mouth if their hands are not clean.
– Should I avoid public places?
Most people can continue to go to work, school and other public places.
The current Government advice states mass events and public gatherings should not be cancelled, and people should continue to act normally for now.
People only need to stay at home and self-isolate if they are advised to do so by 111 or a health professional.
– What are the symptoms?
Initial symptoms include fever, cough, tightness of the chest, shortness of breath and breathing difficulties.
More severe cases can cause pneumonia, sepsis and septic shock, which can lead to death.
There are no specific treatments or vaccines but symptoms can be treated.
– Are some groups more at risk?
The UK Government says most cases appear to be mild and those who have died in Wuhan appear to have had pre-existing health conditions.
The Government says the elderly and people with pre-existing illnesses would be at highest risk.
Overall, around 1% of people who become infected “might end up dying” but this is “significantly” higher among people over 80, officials said.
But officials say “the great majority of people will recover from this virus, even if they are in their eighties”.
