What is the size of the SARS-CoV-2 coronavirus spreading since December 2019? He is responsible for the infection and has led to the COVID-19 pandemic. A single virus is 60 to 140 nanometers in diameter.
The SARS-CoV-2 coronavirus, which is responsible for the COVID-19 infection, is almost spherical in shape. It owes its name to a protein shell with insets that resembles a crown. The diameter of a single virus particle ranges from 60 to 140 nanometers. The molecule is surrounded by protrusions from 9 to 12 nanometers long. (Source).
The coronavirus is similar in size to the ordinary flu virus. The influenza virus is also spherical in shape and ranges in diameter from 80-120 nm.
To better imagine the size of our enemy quote some comparisons:
1 nanometer equals 0.000001 millimeters.
So the SARS CoV-2 coronavirus is 0.00014 millimeters in diameter – assuming its upper size limit.
By comparison, the head of an average pin is 1.5mm in diameter and the injection needle is approximately 0.5mm thick.
