Size Of Coronavirus report

At the end of 2019, a new type of coronavirus previously named 2019-nCoV caused a cluster of pneumonia cases in Wuhan, Hubei Province, China. The virus later spread throughout China and other parts of the world, becoming a global health emergency. In February 2020, the WHO named the disease COVID-19.

Coronavirus is an important pathogen of humans and animals. During the coronavirus epidemic, as many as one-third of upper respiratory tract infections are caused by it. The virus may also be related to severe respiratory tract infections in children and adults. In addition, certain coronaviruses can cause diarrhea in infants and children.

At present, as many as millions of people worldwide have died because of the coronavirus. Medical experts from various countries quickly learned about this virus and developed effective vaccines. It is time to learn more about coronavirus by reading the following article.

Coronavirus Size Guide

Millions of people have to become mask experts due to the coronavirus epidemic. But many people wonder if masks can filter out the coronavirus? There is also such questions on Quora: How small is the coronavirus? There are many types of masks, which ones can stop the spread of coronavirus? Fortunately, scientists have come up with reliable data that can answer these questions.

The coronaviruses genome is a single-strand positive-strand RNA with a size of 27,000 to 32,000 bp, which is the largest of all RNA virus genomes. The International Committee on Taxonomy of Viruses divides CoV into α, β, γ, and δ genera. These CoVs can infect a variety of hosts, including poultry, pigs, and humans.

How big is the Coronavirus Particles

Coronavirus particles are spherical particles with approximately 125 nanometers (0.125 microns) in diameter. The smallest particle is 0.06 microns, and the largest is 0.14 microns. It means that coronavirus particles are smaller than PM2.5 particles but larger than some dust particles and gases.

From COVID-19 to air pollution, some of the world's biggest threats have been microscopic lately. From the global COVID-19 pandemic to wildfires ripping through the U.S. West Coast, it seems as though our lungs can't catch a breath. While the coronavirus that causes COVID-19 is relatively small in size, it is not the smallest virus particle out there.

Can Masks Capture Coronavirus Particles

Researchers at the University of Edinburgh tested different types of commonly used masks. Scientific tests have shown that 3M masks can capture more than 95% of the particles, and the thickness of the particles is only 0.007 microns, which is ten times smaller than the coronavirus. Even more surprising is that surgical masks can also capture 80% of tiny particles.

What is certain is that masks can filter out even very tiny particles. Surgical masks and N95 masks can capture tiny particles more than 10 times smaller than the coronavirus. Maintaining a safe social distance and standard wearing masks can effectively protect your health.

Coronavirus size v.s. Other small particles size

Pollen, salt, and sand are significantly larger than viruses or bacteria. Because of their higher relative sizes, our bodies can usually block them out. A particle needs to be smaller than 10 microns before it can be inhaled into your respiratory tract. The virus-causing COVID-19 is undoubtedly the most topical coronavirus particle right now. It is not the only speck that poses a health risk. Coronavirus particles are smaller than both red or white blood cells. However, a single blood cell is still virtually invisible to the naked eye.

The immune system of COVID-19 patients is over-activated and releases many inflammatory factors, which can trigger an immune response to mediate hematopoietic system damage. COVID-19 is a new infectious disease that can affect multiple organs throughout the body. Direct virus attack and immune damage coexist. Further research on the pathological mechanism is of great significance for understanding the law of occurrence and development of the disease and improving the level of prevention and treatment.
