What are the signs and symptoms of this new virus?
The symptoms of this new coronavirus (now known as COVID-19) include fever and respiratory symptoms including coughing, sneezing, and shortness of breath. The current evidence is that most cases appear to be mild.
If you have a cough, or fever or shortness of breath and have visited any of the following areas in the last 14 days
- Republic of Korea
- Hong Kong
Stay indoors and call NHS 111 informing them of your recent travel to the city.
If you have been to Wuhan, or Hubei province, in the last 14 days, stay indoors and avoid contact with others where possible, and call 111 informing them of your travel. Do this even if you do not have any symptoms.
How many cases do we have in the UK?
As of 24 February, a total of 6,536 people have been tested in the UK, of which 6,527 were confirmed negative and 9 positive. These figures do not yet include the four cases from the Diamond Princess cruise ship in Japan.
The patients are receiving specialist NHS care, and we are using tried and tested infection control procedures to prevent further spread of the virus. Experts at PHE continue to work hard tracing patient contacts from the UK cases.
We will update these figures at 2pm every day.
What’s the current travel advice?
The Foreign and Commonwealth Office (FCO) advise against all travel to Hubei Province and now advise against all but essential travel to the rest of mainland China (not including Hong Kong and Macao). If you’re in China and able to leave, you should do so. The elderly and those with pre-existing medical conditions may be at heightened risk.
The FCO is working to make available an option for British nationals to leave Hubei province. If you’re a British national in Hubei Province and need assistance, contact our 24/7 number +86 (0) 10 8529 6600 or the FCO in London on (+44) (0)207 008 1500.
How does this new coronavirus spread – I’m concerned I could catch it?
Because it’s a new illness, we do not know exactly how it spreads from person to person, but similar viruses spread by cough droplets or sneeze droplets. These droplets fall on people in the vicinity and can be directly inhaled or picked up on the hands and transferred when someone touches their face.
How long any respiratory virus survives will depend on a number of factors; for example:
- what surface the virus is on
- whether it is exposed to sunlight
- differences in temperature and humidity
- exposure to cleaning products
Under most circumstances, the amount of infectious virus on any contaminated surfaces is likely to have decreased significantly by 24 hours, and even more so by 48 hours.
Can the virus survive on cargo that has arrived from an affected area?
There is currently no evidence to suggest that the virus can be transmitted from post, packages or parcels from China.
What can I do to reduce my risk of catching coronavirus?
There are things you can do to help stop germs like coronavirus spreading:
- Always carry tissues with you and use them to catch your cough or sneeze. Then bin the tissue, and wash your hands, or use a sanitiser gel.
- Wash your hands often with soap and water, especially after using public transport. Use a sanitiser gel if soap and water are not available.
- Avoid touching your eyes, nose and mouth with unwashed hands.
- Avoid close contact with people who are unwell.
Should people wear face masks to protect themselves from infection?
Face masks play a very important role in clinical settings, such as hospitals but there’s very little evidence of widespread benefit from their use outside of these clinical settings. Facemasks must be worn correctly, changed frequently, removed properly and disposed of safely in order to be effective.
The best way to protect ourselves from infections like coronavirus is to wash our hands frequently with soap and water or use a sanitiser gel, as well as always carrying tissues and using them to catch coughs and sneezes, then putting the tissue in a bin.
If I live in the area where coronavirus patients are reported as coming from – am I at extra risk?
We ensure that someone with coronavirus doesn’t put others at risk by treating them in isolation and carefully investigating who they had close contact with through contact tracing.
Contact tracing is a fundamental part of outbreak control that’s used by public health professionals around the world.
If a person tests positive for coronavirus, we speak to the patient to identify anyone who has who has had close contact with them during the time they are considered to be infectious and go all out to find these people as soon as possible.
Once we have contacted them we can then give them the advice they need. If they are in groups considered to be a higher risk, we make sure that we follow up with them daily to see how they are. If they become unwell we are then able to assess them quickly and take appropriate action.
Am I allowed to go out to the shops to get food? I need to collect medicine from the pharmacists, what should I do?
Individuals are advised to stay at home for 14 days after arriving from Wuhan or Hubei Province (or elsewhere in China or specified areas if you have symptoms), and avoid public places. Where possible, contact a friend, family member or delivery services to carry out errands on your behalf.
Who will take my kids to school?
We recommend that you stay at home for 14 days after arriving from Wuhan or Hubei Province (or elsewhere in China or specified areas if you have symptoms), and avoid public places. Where possible, contact a friend or family member to take your children to school.
Can we test people for coronavirus and how does this work?
PHE is a world-leader in developing techniques to aid the public health investigation of infectious diseases. The UK is one of the countries outside China to have an assured testing capability test for this disease.
When a clinician suspects novel coronavirus, they take samples from the nose, throat and deeper respiratory tract and send them for laboratory testing.
Using the diagnostic test, scientists can look for evidence of the presence of any type of coronavirus and then hone in on specific genetic clues that identify the novel coronavirus associated with this outbreak.
PHE’s diagnostic test for coronavirus is being rolled out to 12 laboratories across the UK to accelerate the country’s testing capabilities. This increases testing capacity to more than 1,000 people a day for England.
What happens if I’m tested for novel coronavirus?
A doctor or nurse will swab your nose and throat if you need testing for the novel coronavirus. These samples are then safely transported to one of our labs. Testing starts when your sample reaches the lab; it takes 24-48 hours for testing to be done. Once the result is available, it is sent back to your doctor or nurse who will let you know the result and give you advice on what to do next.
How do we know if the virus is evolving?
PHE has used whole genome sequencing to sequence the viral genome from the first two positive cases in this country and has made the sequence available to the scientific community. Our findings are consistent with viral genomes sequenced in China, and we are not seeing changes that suggest the virus has evolved in the last month.
What advice are healthcare professionals being given?
Clinicians in primary and secondary care have already received advice from PHE, covering initial detection and investigation of possible cases, infection prevention and control, and clinical diagnostics.
A Central Alerting System (CAS) Alert will be issued by CMO, Medical Director PHE and Medical Director NHSE/I to frontline staff to increase awareness of the situation and actions to take if potential cases present. NHS England has developed an algorithm to support NHS 111 in identifying suspected potential cases.
