This isn’t a common cold. The confusion is that about 10 to 30 percent of the common colds that everyone else gets during a season happened to be a coronavirus. But a certain subset of coronaviruses can cause the extremely serious disease they did with SARS and MERS, and now it is doing it here with the novel coronavirus.
What is the reason for the Seriousness of this Coronavirus Type?
The mortality (the state of being subject to death) of this coronavirus type is multiple times what seasonal flu is. Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) result in death in about 10% of infections and between 30% to 40% of cases, respectively.
We still don’t have accurate enough numbers to determine the actual percentage of deaths that result from this viral infection, given that there are a great many mild cases, as well as deaths, that have gone unreported.
None of us are Immune
As this virus has never been seen in humans, so absolutely no one is immune to it. COVID-19 virus is found in the upper airway including the mouth and nose. The infection can be spread through coughs, sneezes, huffing and puffing, and likely even loud talking. Infected people are unknowingly spreading the virus days before they begin to experience symptoms. For more exciting stuff please subscribe to our Facebook Page
Stronger than SARS-1
The virus that causes COVID-19 is similar to SARS and is officially called SARS-CoV-2. It gets attached to the same receptors as SARS-CoV-1, but it’s stickier that allows the virus to enter cells more quickly, get a firmer grasp and begin spreading more quickly throughout the body.
This virus also attacks the lower respiratory tract the bronchial tubes and the lungs where it can lead to pneumonia
As a built-in response or inflammatory response, the body (of about 15% of people) attempts to fight the invader, this immune response is called a cytokine storm. Under normal circumstances, Cytokine’s normal immune response tries to kill the virus and clears the virus, and helps produce antibodies and T cells specific for the virus. But in some COVID-19 patients, the cytokine response sticks around too long and too strongly that can severely damage the lungs, which may or may not be directly attributable to the virus, the cytokine storm also can contribute to clot formation, kidney damage, and heart damage. This is what’s causing some people to become severely ill or die. For more exciting stuff please subscribe to our Facebook Page
Gender is another risk factor for COVID-19. Men are dying at higher rates than women. While doctors don’t yet know why research has shown similar patterns of cytokine overreactions based on age and gender with other coronaviruses.
