The new coronavirus is not comparable to the influenza virus, but more like the old SARS virus. So what do we know about the new coronavirus SARS-CoV-2 that causes this disease COVID-19?
1. There are many more types of coronaviruses
The new coronavirus belongs to a larger group of coronaviruses. The many coronaviruses differ from each other. Some are so weak that they can only cause colds. Others are so strong that they can kill people.
2. The new Coronavirus most closely resembles the SARS virus
COVID-19 is more than 87% similar to the coronavirus that caused the SARS outbreak in 2003, which is called "SARS coronavirus". In fact, this new coronavirus is so similar to the old SARS virus that it has been called "SARS coronavirus 2" in science.
3. Covid-19 hijacks the ACE2 enzyme to infiltrate the body
The new coronavirus, the original SARS coronavirus and only one other known coronavirus; called "human coronavirus NL63", find their way into cells by hijacking a substance called "ACE2". Angiotensin-Converting Enzyme 2, abbreviated to ACE2 directly affects the functioning of the cardiovascular system. The enzyme is mainly found in vascular endothelial cells of the heart and kidneys. The endothelium is a single-celled layer of cells that lines the inside of the heart, blood vessels and lymph vessels, among others. Studies have shown that the SARS coronavirus invades humans through the ACE 2 receptors. The SARS-CoV-2 coronavirus appears to bind to ACE 2 as much as 10 to 20 times faster compared to the old SARS-CoV virus. Under normal circumstances, ACE2 helps control our blood pressure and keep our lungs and heart healthy, but these three coronaviruses are using it as a back door to infiltrate our cells. Virtually all other viruses, including all other known coronaviruses, use completely different ways to get into our cells. Only these three go this way.
Chinese researchers have discovered that ACE2 receptors are also found on fat cells. This would explain why more than 80% of people who end up in intensive care because of corona have a BMI higher than 30.
4. The new coronavirus turns the antibody 'inteferon' against our own bodies
SARS and another coronavirus known as Middle East Respiratory Syndrome (MERS), which emerged in 2012, evade, undermine and hijack our own natural antiviral defenses; interferon. Given the similarity between the new coronavirus and SARS, and given the similarity of the lung diseases caused by all three viruses, it is likely that the new coronavirus has a similar way of turning our interferon response against us. Interferons (IFN) are natural proteins secreted by infected cells. They play an important role in the functioning of the immune system. The effects of interferons against viruses were discovered in 1957 by Alick Isaacs and Jean Lindenmann. They are called interferons because they normally interfere with the multiplication of a virus in the body. There are about 20 different types of interferons in the human body. These different types of interferons are normally important in fighting acute and chronic infections. Covid-19 appears to reverse this action, as did SARS and MERS, against our own bodies.
5. The new coronavirus is a lipid-envelope virus so it does not tolerate soap well
Coronaviruses belong to a larger group of viruses known as lipid-envelope viruses. They have an oily coating that protects them from our immune system. But this oily coating of the COVID-19 virus makes it vulnerable to soap and to certain substances in foods and supplements that can penetrate or dissolve the oily coating. This is also why the virus does not tolerate detergents such as soap well. A virus envelope allows viruses to more easily bypass the immune defense system of a host or to better adapt to a new host. HIV, the SARS coronavirus, the influenza virus, the Ebola virus and the West Nile virus also have a virus envelope. This is in contrast to a virus without an envelope, also called a naked virus. This type of virus can build its DNA into the DNA of the host. Each time the host cell divides, the DNA of the virus is copied. The virus does not directly kill the host cell, because it needs the host cell to survive. However, the virus can break out if the immune system is weakened. An example of a virus that reproduces in this way is the herpes virus, which causes cold sores, among other things.
