- Why Coronavirus Is Much More Scary Than Seasonal Influenza
The COVID-19 Virus has a type of genetic code sequencing called RNA and is a novel (new) virus that had, in December 2019, jumped from animals to humans. The human immune system does not recognize COVID-19 and thus humans cannot build protective immunity against it quickly.
In contrast the influenza virus has a genetic RNA code that makes it easily recognized by the human immune system. Thus, your immune system can spring into defence action quickly. The more recently you had a bout of influenza the better your new seasonal flu immunity will be. You get immunity against the flu either by exposure to a seasonal flu virus, or by getting a flu shot.
New or Novel viruses, like COVID-19 come from animals and thankfully these viruses usually only transfer from animal to animal (pigs in the case of H1N1). The 1918 influenza pandemic was the most severe pandemic in recent history and was caused by an H1N1 virus with genes of avian origin and jumped to humans.
If one of these animal viruses mutates (changes its RNA or DNA) it then becomes able to transfer from animals to humans – wow, then the drama begins! This is because humans have NO natural or acquired immunity because the RNA sequencing of the genes inside the virus isn’t human. If the human immune system doesn’t recognize this new enemy it cannot fight it. It has become a stealth virus – scary right?
A viral mutation may only allow transfer from animal to human and it may stay this way for years. Viruses are clever and are designed to keep mutating and finally it will mutate into a form that allows transfer from human to human – now we have a new contagious phase and that’s what’s happening now with COVID-19.
The Coronavirus existed in animals only for an unknown period of time until it got its chance to mutate at an animal market, in Wuhan China, in December 2019. Unfortunately, this enabled it to jump from animals to people. Initially only animals could give it to a human but in just TWO WEEKS it mutated again and achieved the ability to jump from human to human. This “slippery virus” became a stealth virus.
This COVID -19 Coronavirus had never before been a “human” virus so humans had NO natural or acquired immunity. This was a viral once in a lifetime opportunity, and it spread rapidly with no barriers. No wonder we currently have no drugs or vaccines to fight it.
COVID-19 mutated in such a way that gave it the ability to cause severe damage to human lungs.
COVID-19 is very different from seasonal influenza or H1N1 or the common cold virus in that it can rapidly destroy the air sacs in the lungs and the patient drowns in their own lung secretions. Worryingly COVID-19 has already mutated again and we now have two strains to combat – strain s, and strain L. this increases the challenge for virologists to make an effective vaccine.
What can we do? Immediate and rapid closings of public crowded places have helped in past new pandemics. Philadelphia and Baltimore were reluctant to close events in 1918 and they were the hardest hit in the US during the Spanish Flu.
COVID-19 is a new enemy with a huge propensity to change its genome again so we have to deal with unpredictability.
I encourage all people to keep their immune system strong with good nutrition, adequate rest and specific supplements. Just be smart but do not be anxious as stress will weaken your immune system.
COVID-19 virus obstructs the respiratory pathways (tract) with thick mucus that hardens and blocks the airways and air sacs (alveoli) in the lungs. If we can thin the mucus and reduce the outpouring of fluid in the air sacs, we have a better chance of surviving.
