Introduction[edit | edit source]
Scientists have known of the human coronavirus since the 1960s. But only rarely has it garnered wider recognition over the past half a century.
The International Committee for the Taxonomy of Viruses has approved the naming of more than 40 coronaviruses. The vast majority of these infect animals. The COVID-19 outbreak has brought the number of identified coronaviruses that infect humans to seven.
Four of these are community acquired and have circulated through the human population continually for a very long time. The four community-acquired human coronaviruses typically cause mild cold-like symptoms in humans. Two of them, hCoV-OC43 and hCoV-229E, have been responsible for between 10% and 30% of all common colds since about the 1960s.
Three of these (SARS-CoV, MERS-CoV and SARS-CoV-2) appear to have jumped to the human population more recently. Worryingly, these three result in a high mortality rate.
All coronaviruses are zoonotic. They start off in animals and can then, following mutation, recombination and adaptation, be passed on to humans[1].
