What is Coronavirus/Covid-19?
The Coronavirus, known officially as COVID-19, is a virus that appears to have originated in the Wuhan Province of China in late 2019. It has since gone on to affect over 100,000 people around the globe, causing over 3,000 deaths.
We don’t fully know how dangerous the virus is, as it is a novel strain which is previously unknown to us. However, the mortality rate is fairly low (about 2%) and typically appears in more elderly or immunocompromised people. For comparison, the seasonal flu has a mortality of about 1%. The crucial difference here is that there is no vaccine available yet for the Coronavirus and there are no proven treatments to date.
Coronaviruses are not uncommon, but primarily cause illnesses in animals. All viruses mutate over time and will differ in severity and ability to spread. Over the last few decades, there have been several widespread strains of Coronavirus such as SARS and MERS, which have caused significant mortality. Covid-19 does not seem to have the same mortality rate as SARS (10%) or MERS (30%), however it has spread much faster than these strains, meaning that it has rapidly become a global concern.
What are the symptoms?
In most people, those infected with Covid-19 will exhibit mild symptoms, if at all.
It can take up to 14 days for people exposed to the Coronavirus to express symptoms.
Symptoms can include, fever (high temperature), cough, shortness of breath (indicating more serious illness) and breathing difficulties. Symptoms do not tend to include a runny nose.
Most cases are mild and will resolve, however some (approximately 15-20%) can develop symptoms which require significant medical support.
How is it spread?
Covid-19 is spread via ‘close contact’ with someone who has Coronavirus and is spread by the sneeze or cough droplets, in much the same way as a cold or flu. Close contact, in this case, means spending 15 minutes within 2 metres of an infected person or living in the same house as an infected person.
The virus can be contracted by airborne transmission (i.e. breathing in the droplets of an infected person) or by touching a surface that has been coughed or sneezed on, and then touching the eyes, nose or mouth.
How do I help prevent the spread of the virus?
There are a number of simple steps that can be taken to help protect yourself and others from coronavirus.
As this situation is rapidly evolving, local guidelines will change and be updated frequently. It is important to familiarise yourself with these guidelines.
Should I be tested?
Covid-19 testing is being co-ordinated by national public health departments. Latest guidelines recommend testing for:
If you are concerned that you may fit the above criteria, please follow local public health advice with the contact information below, DO NOT go to your local GP practice as you may risk spreading the virus to others.
