Coronaviruses, COVID-19 and our pigs
PIGS cannot get COV- ID-19 and will not give you COVID-19.

Though there are also types that are very se- rious, including severe acute respiratory syn- drome and Middle East respiratory syndrome.
A new form of this vi- rus appeared and is now spreading worldwide.
To date there is no evi- dence of any animal trans- mission with this new cor- onavirus COVID-19.

They are so called be-
Our pigs can get their own coronaviruses, which have a range of clinical problems.
This is a human virus and a human problem.
cause down the electron microscope they look like the corona of the sun.
They are a difficult family to control and vaccination generally produces poor protection.
Porcine epidemic diar- rhoea affects the intes- tines of piglets less than 10 days of age with fatal consequences.
The evidence is point- ing to a person in Wuhan becoming the first case in November 2019.
This virus family is thousands of years old.
There was a report of the virus being found in a dog in Hong Kong, and though the virus was lo- cated, it was not replicat- ing and the virus died out in the dog without pro- ducing any clinical signs.
The virus family lives in many species of mammal, birds and other reptiles.
Which makes them challenging to manage because new forms will constantly emerge and the host (animal and hu- man) population will have little or no immu- nity to the ‘new’ form.
There have been no cas- es – zero – of pigs getting
Man has many known coronaviruses, with vari- ous human coronaviruses identified before 2019 re- sponsible for 15 percent of all common cold cases.
This is what happened at the end of 2019.
Though these viruses do not infect people.
The corona is formed from a variety of spikes that stick through the oily envelope.
Their genetics are based on RNA and this means they can easily change.
Porcine respiratory coronavirus affects the breathing of pigs caus- ing a mild cough and sneeze, similar to human seasonal colds, which can be dramatic but the pigs recover.

COVID-19 in humans has a similar history.
These coronaviruses do have a weakness – they have a layer of fat on the outside of the virus and if this is removed the virus cannot function.

For this reason, washing your hands carefully with soap and water for at least 20 seconds, ideally with a nailbrush, is a great idea.
Washing your hands to remove viruses can be difficult as illustrated on the previous page using an ultraviolet soap, which students use to teach them good hand biosecurity.
