Answer:
1) COVID-19, which is caused by the new coronavirus, has been dominating the news lately. However, you may have first become familiar with the term coronavirus during the severe acute respiratory syndrome (SARS) outbreak in 2003.
Both COVID-19 and SARS are caused by coronaviruses. The virus that causes SARS is known as SARS-CoV, while the virus that causes COVID-19 is known as SARS-CoV-2. There are also other types of human coronaviruses.
2) From "Wuhan virus" to "novel coronavirus-2019" to "COVID-19 virus," the name of the new coronavirus that first appeared in China has been evolving to its now official designation: SARS-CoV-2.
3) Spherical or pleomorphic enveloped particles containing single-stranded (positive-sense) RNA associated with a nucleoprotein within a capsid comprised of matrix protein. The envelope bears club-shaped glycoprotein projections.
4) The genome size of coronaviruses ranges from approximately 26 to 32 kilobases.
5) virus is an infectious particle that reproduces by "commandeering" a host cell and using its machinery to make more viruses.
A virus is made up of a DNA or RNA genome inside a protein shell called a capsid. Some viruses have an external membrane envelope.
6) In food especially enveloped ones as they may increase my belly fat but I do prefer to track and hunt them. The first part of the answer of Denis "SNOM or other device with sub-wavelength aperture for optical spectroscopy" is very interesting and it makes sense.
