Use the term “pandemic” when referring to the coronavirus (COVID-19) pandemic rather than “outbreak”. You should always use “coronavirus” before “pandemic” on the first use in a section. Once you have introduced this term, you can use just “pandemic” in other instances in that section.
A pandemic is where a disease is prevalent over a whole country or the world and so is more accurate than outbreak, which refers to increases of a disease in a particular time or place. The World Health Organization classified COVID-19 as a pandemic on 11 March 2020.
Avoid using the phrase “pre-pandemic”. See Pre-coronavirus, pre-pandemic and pre-lockdown.
