Seven human coronaviruses (HCoVs) have and can still harm humans. The present one, COVID-19, has the world in the grip of its microscopic spikes.
It has caused immense polarity, hatred towards governments, doctors, and people of power, such as Bill Gates and Dr. Anthony Fauci.
It has created absurd conspiracy theories. But most of all, COVID-19 is an invisible serial killer, and if it does not kill you, it may cause long-lasting damage to your heart, brain, and lungs —REGARDLESS OF AGE!
Many people in this world act like COVID-19 is just like a cold or the flu. However, this is far from it.
This article will provide you with in-depth information on human coronaviruses, their strengths, weaknesses, and their sneaky methods of spreading that are not being shared anywhere else.
A Brief History Of Human Coronaviruses
The seven human coronaviruses were discovered in this order as follows:
- 229E strain (Causes mild symptoms of the common cold) (1965) (1)
- OC43 strain (Causes mild symptoms of the common cold) (1967) (1)
- NL63 strain (Causes cold-like symptoms) (2004) (1)
- HKU1 strain (Causes cold-like symptoms) (2005) (2)
- SARS-CoV – Severe Acute Respiratory Syndrome ( This deadly coronavirus caused flu-like symptoms but also caused respiratory, heart and liver failure) (3) (2002) (4)
- MERS – Middle East Respiratory Syndrome (caused lower respiratory tract infection in humans with a 35% mortality rate) (2012) (5)
- SARS-CoV-2 – COVID-19 (This deadly coronavirus causes respiratory problems, loss of taste and smell, blood clots, strokes and embolism, heart and lung damage, and attacks the brain). The mortality rate was more than 50% for those over the age of 60. (6) (2019)
However, although the first human coronavirus was discovered in 1965, there is scientific evidence that they existed between 190 and 489 million years ago.
Also, the public is being told that the weaker strains of the human coronaviruses only cause cold-like symptoms. However, this is far from the truth, as will be shown with evidence.
What You Are Not Being Told About Coronaviruses
Let’s begin with the weaker, milder HCoV strains (229E, OC43, NL63, HKU1). Do they only cause cold-like symptoms?
The answer will surprise you. People from around the world have been catching colds from the milder coronaviruses since the mid-60s.
But they have caused much more damage. These mild coronaviruses are not as benign as many people believe. They are not your ordinary common cold.
They have been associated with more severe diseases of the lower respiratory tract, such as bronchitis, bronchiolitis, pneumonia, and croup (an acute respiratory illness that attacks babies) by HCoV NL63.
They have also caused troublesome nosocomial infections, particularly in neonatal care units. (Nosocomial – infections caught in a hospital setting).
Studies show that they have caused enterocolitis in newborns, diarrhea, and other gastrointestinal infections.
Further studies have demonstrated that these so-called common cold viruses have been implicated in central nervous system diseases such as multiple sclerosis, neurological problems, and heart trouble.
Also, these viruses are at their peak during the winter months.
Coronaviruses Can Survive In Different Conditions
HCoVs are RNA enveloped viruses. Generally, enveloped viruses are weaker than the non-enveloped counterparts. But not in the case of coronaviruses, these rules do not apply.
The following study states the following:
- “Another interesting feature of coronaviruses is their potential environmental resistance, despite the accepted fragility of enveloped viruses. Indeed, several studies have described the ability of HCoVs (i.e. HCoV 229E, HCoV OC43 (also known as beta coronavirus 1), NL63, HKU1 or SARS-CoV) to survive in different environmental conditions (e.g. temperature and humidity), on different supports found in hospital settings such as aluminum, sterile sponges or latex surgical gloves or in biological fluids.“
Transmission of these HCoVs is usually through respiratory droplets and physical contact. However, there is evidence that many people have been infected by other means.
One example is when passengers on a fight got infected with SARS, although they made no contact or were near the infected person.
In another SARS infection incident, one infected man visited his brother on March 14, 2003, in a housing estate and used the bathroom there.
By April 15, 2003, 321 people in that estate became infected with SARS. The evidence indicates that these infections were not from respiratory droplets or physical contact.
Can COVID-19 Be Spread Without Physical Contact Or Respiratory Droplets?
Although it is too early to tell, there have been unexplained incidents of people getting infected without them ever being near an infected person or a high-risk infection area.
An article published by the New York Times on July 20, 2020, explains a strange situation that took place in Hong Kong that has top health experts puzzled.
Hong Kong had appeared to have COVID-19 under control with its strict measures and containment strategies.
However, the country suddenly began having a multitude of people becoming infected. The experts are confused because they are unable to contact-trace the infections. They are perplexed because “Most people who tested positive for the virus have not traveled and have not been linked to known clusters.”
So, the dilemma is if the infected people have not been around any high-risk environment or infected clusters of people, how did they become infected?
The question that needs to be asked is if other HCoVs can be airborne, why wouldn’t COVID-19 be able to do the same?
In a recent News Feature article published and updated by Nature on July 23, 2020, it explains that there is mounting scientific evidence that COVID-19 is airborne.
Aerosol scientists and 237 other clinicians, infectious-disease physicians, epidemiologists, and engineers, are urging health officials to change their policies as to how COVID-19 can be spread.
Interestingly, the World Health Organization agreed that COVID-19 “short-range aerosol transmission cannot be ruled out in crowded, poorly ventilated spaces.”
This is a serious matter, especially when someone enters an elevator, or walks up a stair-case or hallway that is poorly ventilated. He or she will be like a worm in a fish pond.
The problem is that there is up-to-the-minute research showing that COVID-19 is also airborne. (See the video below, published on August 21, 2020) Scientists have declared that the primary transmission route indoors is through aerosols.
What is scarier is that even during the hot summer months where ventilation is highest, COVID-19 has not slowed down a bit. What will happen when it gets colder?
In a preprint scientific report (not yet reviewed or evaluated for use in clinical practice), it was shown that COVID-19 could survive in the water up to 25 days, and the possibility exists that it can spread through fecally contaminated water.
Health Researchers And officials Question The Importance Of Aerosol And Airborne Transmission
Since the 1930s, researchers have agreed that respiratory viruses smaller than 5 micrometers in diameter (such as flu viruses) are unlikely to be airborne transmissible. Let’s look at the evidence.
In an elaborate study, scientists have determined that the deadly Avian flu virus is able to be wind-borne for up to 25 miles. Forget airborne; they said WIND-BORNE!
In another exciting story published in Nature on April 4, 2012, Kawasaki disease was shown to glide in the atmosphere for 1000s of miles to infect people. Although Kawasaki disease is not a virus, it has been associated with viruses, including coronaviruses.
If you read the ending of the Nature article, you will find the following words:
- “And, of course, what other diseases are blowing in the wind? Taiwanese scientists, noting that outbreaks of avian influenza often occur downwind of dust storms, found influenza virus in air samples, and found that concentrations of the virus spiked when dust storms blew in from central Asia. So, says Burns, “why don’t we acknowledge the possibility that agents important for human health could be traveling on these wind currents?”
It appears that viruses can go wind-borne. Is COVID-19 strong enough to survive in the wind? Let’s look at what temperatures and humidity HCoVs can survive in.
Coronaviruses Survival Ability In Different Temperatures And Humidity
In December 1985, a scientific study labeled the first discovered HCoV 229E an “airborne coronavirus.”
The study detailed how potent coronaviruses are at surviving in different temperatures and humidity. They said,
- “…the role of the environment on the survival of viruses in air may be more complex and significant than previously thought.“
HCoV 229E was tested for its survival potency in weather conditions. It was discovered that high humidity weakens the virus. However, if the temperature dropped to 6 °C (43 °F) and no matter the humidity level, the virus was at its peak potency.
More interesting, HCoV 229E was even stronger if the weather was 6 °C (43 °F) with high relative humidity. (See, chart)
They also tested the first SARS-CoV. This coronavirus would be killed if it was exposed at 56 °C (132.8 °F) for over 30 minutes. The problem is that such temperatures are never reached in our living environment.
SARS-CoV could also survive in cold weather. When it was placed at 4 °C (39 °F), there was no loss of infectivity strength.
Another study proved that SARS-CoV could survive at 20 °C (68 °F) and 37 °C (98.6 °F) for at least 2 hrs.
The research paper emphasized the following words: (See section “3.2. Suspension vs. Desiccation“)
- “These studies firmly illustrated the potency of coronaviruses and especially the SARS-CoV.“
Human coronaviruses are not like the flu or the common cold. They are much more dangerous because they can cause various symptoms and attack different organs in your body, including killing you. They have an uncanny ability to survive in all types of weather conditions.
We are presently at the peak of summer 2020 with extremely high heat worldwide. Did COVID-19 slow down? On the contrary, as of August 21, 2020, infection cases have begun to increase in many countries.
Remember, HCoVs are at their peak infection state when it gets cold. Winter will be coming soon. There will be less ventilation, fewer windows open, less fresh circulating air.
If people let their guard down this winter and assume that COVID-19 cannot harm you, then you have a surprise coming. COVID-19 is not going away any time soon.
Stay ready, safe, and vigilant.
