You will have heard a lot about COVID-19 (coronavirus) in the news and online. But you don’t need to panic. This unit covers all the essential information you need to know right now, including:

  • What it is
  • How it spreads
  • How to prevent infection
  • What you should do if you suspect you are infected

COVID-19 is a coronavirus. Coronaviruses are a large family of viruses that get their name from a halo of spiked proteins around their surface. It's said to look like the corona (in other words, the outermost part of the Sun’s atmosphere) of the Sun if you look at it under a microscope.

The first outbreak was in Wuhan province, China. From there, it has spread around the world. 


Data from the Chinese CDC (28th Feb) found that 81% of COVID-19 cases were considered mild. 14% of cases were considered severe and 5% critical.

We are still learning about what happens upon infection, but here is what we do know. COVID-19 can span from a mild infection to a severe illness. The most up to date data from the WHO-China Joint Mission suggests that of those infected:

  • 88% had a fever
  • 68% had a dry cough
  • 38% had fatigue
  • 33% coughed up phlegm
  • 19% had shortness of breath
  • 15% had joint or muscle pain
  • 14% had a sore throat
  • 14% had a headache
  • Less common symptoms include: chills, nausea or vomiting, nasal congestion, diarrhoea

Current information suggests that COVID-19 spreads in two different ways:

1: It is primarily spread through droplets. These are the tiny particles of water projected when you cough, talk, sneeze and breathe. 

2: COVID-19 can live on surfaces. The World Health Organization currently says that it can live on surfaces for a timespan of between a few hours and a few days.


You can help protect yourself by thoroughly washing your hands.

  • Regularly wash your hands with soap. 
  • Wash your hands thoroughly. Follow the guidance above and make sure that you wash your hands for at least 20 seconds.
  • Carry and use hand sanitiser that’s at least 60% alcohol.

  • Use disinfectant on commonly touched surfaces. Make sure that your disinfectant is 62–71% ethanol, 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite (bleach). This will neutralise any COVID-19 within 1 minute.
  • If you know someone is unwell, try to stay at least two meters away from them.

It's important to not just keep yourself safe but to do everything you can to keep others safe as well. Here are some ways you can do that:

  • Cough and sneeze into a disposable tissue, then dispose of the tissue into a lidded bin. 
  • If you don't have a tissue available, cough or sneeze into your elbow. This stops you getting droplets on your hand and transferring them onto the things you touch. 
  • If you are at all unwell (even a very mild cold) try to self-isolate yourself where possible. For example, if you have a cough or cold, avoid coming into work or attending social gatherings. It’s possible you have a mild form of COVID-19, but it could express more severely in someone else you know.

If you think you might have COVID-19, then ring up your doctor or healthcare provider. Don’t just turn up.

When you call they will instruct you on what you should do.  

This is important for two reasons, firstly it will help you get the treatment you need. Secondly, it will help local healthcare providers track the spread of the virus so that they can identify who else might be at risk.

Side Note: As COVID-19 is a viral infection, antibiotics won't help fight the infection. 


Here are the most important points for you to remember:

  • Regularly and thoroughly wash your hands with soap or sanitiser.
  • Avoid touching your eyes, nose and mouth. 
  • If you feel unwell ring your local healthcare provider.
