Close-up images of cells in the airways infected with the emerging corona virus showed a terrifying sight of how the virus had invaded the cells lining the airways in the human body.
The images give an idea of the large number of virus particles that are produced during infection, since the infected cells can reproduce thousands of these particles.
Camille Erie, an assistant professor at the University of North Carolina School of Medicine, was able to capture images using an advanced electron microscope.
To obtain the images, which were published Wednesday in the medical journal “New England Medicine,” the researchers injected the Corona virus into cells of the human respiratory tract in the laboratory, and then examined them four days later.
And the Covid-19 virus particles appear in the images as small balls surrounded by thorns resembling a corona, which gave the virus its name known as “Coronavirus.”
The virus uses these spines to invade human cells. The image also shows a high density of virus particles within the human respiratory tract.
Dr. Camille said that analysis of the concentration of the virus in the sample indicates the production and release of a large amount of virus in every cell in the airways.
And last June, researchers at the University of California, San Francisco discovered that the human cell, after being infected with the Coronavirus, secretes what looks like multilateral claws that resemble spikes, and contains particles of the virus, to help it spreads to various parts of the body.
The new Corona virus has killed more than 863,000 people at least since it appeared in China last December, and more than 26 million confirmed cases have been recorded, while at least 17 million people have recovered.
The United States is the most affected country in the world, with 185,752 deaths out of more than six million injured, according to Johns Hopkins University, followed by Brazil, India and Mexico.
