Overview & Key Concepts

Who is John Campbell?

My name is John Campbell. I am a retired Nurse, Teacher, and A&E nurse based in England. I also do some teaching in Asia and Africa when time permits

These videos are to help students to learn the background to all forms of health care. My PhD focused on the development of open learning resources for nurses nationally and internationally.

What is COVID?

Coronaviruses are a group of viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that are

typically mild, such as the common cold, though rarer forms such as SARS, MERS, and COVID-19 can be lethal. Symptoms vary in other species: in chickens, they cause an upper respiratory tract disease, while in cows and pigs they cause diarrhea. There are yet to be vaccines or antiviral drugs to prevent or treat human coronavirus infections.
