Is it covid 19 covid 19 coronavirus or coronavirus disease

The correct term is actually a bit of a story.

Initially, the disease was referred to as "Coronavirus disease 2019" (COVID-19) by the World Health Organization (WHO) in February 2020. The "2019" part refers to the year the outbreak was first detected.

However, the virus itself was initially referred to as "SARS-CoV-2" (Severe Acute Respiratory Syndrome Coronavirus 2). This is because it was a new strain of coronavirus that was different from the one that caused SARS (Severe Acute Respiratory Syndrome) in 2003.

Later, the WHO officially changed the name of the disease to "COVID-19" in March 2020, dropping the "Coronavirus disease" part. This was done to simplify the name and make it easier to use in everyday conversation.

So, to summarize:

• "COVID-19" refers to the disease caused by the SARS-CoV-2 virus.
• "SARS-CoV-2" refers to the virus itself.
• "Coronavirus" is a general term that refers to a family of viruses that can cause respiratory illnesses, including COVID-19.

It's worth noting that the WHO has also officially dropped the term "Coronavirus" from its official name, and now only uses "COVID-19" to refer to the disease.
