The new COVID-19 coronavirus has infected 2.2 million people worldwide. More than 700,000 people in the United States have been diagnosed, most in the world.
What does the new coronavirus look like?
The U.S. Centers for Disease Control has published an original virus image from the first case in the United States that looks like a small pizza sausage.
A new coronavirus is an RNA virus that is very small. Previous shots were actually processed so that everyone could see clearly. Now, a virus picture published in the United States is a real body detected by an electron microscope. The blue object is the new coronavirus whose official number is SARS-COV2, and COVID-19 is the name of the disease infected with SARS-COV2.
Of course, the virus itself is not blue. The above picture is for better distinction. This original electron microscopic picture is as follows:
The small black dots inside, like ladybugs, are SARS-COV 2 viruses. They are so small that they cannot be detected by ordinary optical microscopes. Only electron microscopes can be used.
Testing a new coronavirus is a problem worldwide, why not use an electron microscope to identify it?
Forbes cites experts who claim that because this electron microscope is too expensive, it costs more than $ 1 million, and most medical facilities do not have this condition.
In addition, even if it is affordable, an electron microscope needs professionally trained people to use it, even if it is not a problem. Since there are many types of new coronavirus. Scientists may not be able to recognize the exact images of the SARS-COV2 virus.
Prior to this, the images of the new coronavirus that you saw were mostly colour photographs published by The Lancet Magazine
