What we know and do Not know about the COVID-19 coronavirus

To debunk bogus news circulating regarding the virus, also be certain about the present scientific understanding of this virus Euronews interviewed Morgan Gaia, a researcher about the co-evolution of cells and viruses in the French public study team CEA.

SARS-CoV2’s family of viruses isn’t unknown to science, however, the particular qualities of human ailments related to this SARS-CoV2 breed (like incubation period ) have to be analyzed in complete, Gaia explained.

What’s more, the numerous lifestyles, climates and authorities measures in states affected by the virus are parameters which impact the data scientists have,” he clarified.

Understanding of this virus grows daily, but the current avalanche of preliminary scientific books on COVID-19 has confounded the media and the people more.

This is the event of chloroquine, which despite not being a clinically known remedy is currently sold out from pharmacies throughout the world. Another highly criticized research has indicated that good particle contamination might be a vehicle for the spread of this virus.

Euronews have a peek at what we know for certain, and that which remains unknown about the publication COVID-19 coronavirus.

What do we understand about the brand new SARS-CoV-2 coronavirus?
The publication COVID-19 coronavirus spreads exponentially and easily. “It’s projected that, with no containment steps, an infected individual may infect an average of two or three individuals”, Gaïa clarified.

“Additionally, there are documented instances of’super contaminators’, in other words, infected men and women that, for reasons which aren’t well known, contaminate a greater amount of individuals. This is eased by the absence of resistance of the populace, since it’s a new virus”

Researchers point out that the coronavirus spreads rapidly as it’s practically”invisible”: in many situations, approximately 50 percent and possibly more, it doesn’t result in symptoms or just mild symptoms, somewhat like a flu or a frequent cold.

Gaïa pointed out that”although these instances might be roughly 50% less infectious than those with more complex symptoms, their high amount is a significant contributor to the spread”

Lack of preparation from several nations

Many nations’ lack of preparation from the face of a pandemic, along with the slow response of the government and citizens, has resulted in the present situation, using a third of humankind in lockdown to slow down the spread of the virus.

“In Asia, they’re better prepared because they’ve experienced other epidemics and they’re more disciplined when it comes to protecting themselves and implementing isolation steps,” Gaïa explained.

Authorities often wait to apply unpopular steps, which may lead to panic and possibly harm the market.

The simple fact that it’s emerged in a city of 11 million individuals, hyperconnected from sea, land and air — in China, a nation regarded as the”factory of the world” — has cultivated this unprecedented situation.

Ignorance concerning the virus

Another difficulty has been the absence of knowledge and communication between scientists, governments and the general public.

There are doubts concerning the Chinese scientific community’s adaptation to global scientific standards in addition to concerning the effect of Chinese governments in their books.

“A great deal of this research has just been printed in Chinese,” Gaïa stated, “often without apparent statistical statistics.”

The flagging of symptoms like cough and fever at the first phases of the outbreak as evidence to isolate the ill was likewise a misstep since it disregarded the fact that carriers may show no symptoms or mild symptoms. This, in turn, slowed the government’ capability to impede the spread of this virus.

It Wasn’t created in a lab

The researcher flatly denied conspiracy theories about a”laboratory-created” virus, including that viruses play a regulatory function in character, which although COVID-19 has obtained most authorities around the world by surprise, it was expected that at some stage a similar pandemic could happen.

He pointed into the reduction of biodiversity and our influence on the environment among the causes.

“When we decrease the space between the natural universe and the human world, once we leave little area for wild plant and animal species, we promote viruses which are organic to additional species to be moved human beings and scenarios in this way,” the research said.

Quite diverse effects on the Body

Also, we know that the virus is capable of inducing severe respiratory syndrome and maybe even death.

And it doesn’t just affect the elderly.

When disease occurs, it’s capable of producing, as well as pneumonia, a chain reaction that may affect organs. Your human body’s immune reaction is often so intense it may harm wholesome tissue.

The disorder affects kids hardly any. They create fewer symptoms and there are not many instances of minors affected by acute forms of this virus.

Yet children can take the disease, and that’s why among the very first steps globally was shutting schools.

The new coronavirus is proven to invade cells due to its capacity to”hack” the mobile’s ACE2 receptor.

Risk variables

Age is the deciding factor in creating severe symptoms that could endanger the individual’s lifestyle.

The majority of the deceased and serious cases are guys. Additionally, it appears to be demonstrated that individuals with hypertension, diabetes as well as cardiovascular disease and chronic respiratory ailments are more likely to suffer complications in COVID-19.

Blood groups also have been analyzed and also the blood group A appears to become vulnerable.

What we do not know about the brand new COVID-19 coronavirus

Regardless of the tsunami of advice regarding which we are subjected daily, we still understand very little about the new virus.

The actual amounts of verified cases and death tolls

Many nations, with few exceptions, are now very limited in regards to testing.

Additionally, there are differences in how they account for deaths and cases.

Morgan Gaïa points out that”some states also lack the funds to centralize their information, while some might lack transparency”

Lack of proof

The simple fact that many governmental and ethnic personalities have declared that they’ve COVID-19 highlights the simple fact that they have simpler access to evaluations, despite mild or no signs. The limited capability to perform evaluations makes it impossible to understand the actual quantities of the pandemic now.

More precise estimates can only be produced out of serological analyses, which might demonstrate the percentage of the populace that currently contains SARS-CoV-2 antibodies.

Based on Gaïa, the ability and reliability of the evaluations”will also be influenced by the phase of disease in a patient along with the origin of the sample” (nose, or throat).

“It won’t be possible to check all of humankind at any given moment”, Gaia added. “We could only have quotes and simulations.”

The percentage of cases

Initially ignored, an increasing number of studies indicate that the high percentage of esophageal cases (without symptoms or with moderate symptoms) has favored the spread of this pandemic. The WHO estimates that 80 percent of people may experience symptoms.

Everything suggests, then, the real quantities of contagion are substantially greater than the official ones. And hence, the true mortality rate of this virus is a lot lower.

Just how long are individuals infected

Thus the significance of generalized lockdown and social bookmarking steps.

Chinese studies have demonstrated that the virus could be found in patients (and so possibly transmitted) for 2 to 37 days, with a mean of 20 days.

Also, we do not know for certain if the virus has been transmitted solely by saliva droplets from the atmosphere (like when somebody sneezes) or even by the breath of an infected individual.

It’s been estimated that the virus may remain up to 2 or 3 times on steel and plastic, 24 hours cardboard up to 3 hours at the air – however just in lab conditions. Humidity and chilly are thought to help it endure.

Hand washing and avoiding crowds continue to be the best barriers against it.

The resistance of people who have taken the disorder

Chickenpox resistance lasts a lifetime, but resistance to colds due to other kinds of coronaviruses is quite brief, so people can grab them several times in precisely the same winter.

Every season, it’s crucial to create new vaccines.

COVID-19’s precise source

It likely came out of bats and has been transmitted to people by the pangolin, but so far there’s no certainty.

Researchers think it’s a combo of viruses.

“Viruses circulate into a populace that behaves as reservoir species’ (in the event of coronaviruses, frequently bats, which are extremely resistant) then it’s transmitted into an intermediate species where it adapts, before being transmitted to people.”

Therapy and vaccines

There’s not any proven effective therapy.

There’s a lot of discussion of chloroquine, but nothing was confirmed.

Laboratories all over the world are working on clinical trials to discover a vaccine, which might take over a year to be produced and dispersed.


Although summer and warmth are predicted to slow the pandemic at the northern hemisphere, according to access data on other germs, it isn’t known if it is going to spread in successive waves, even since the Spanish flu did, for instance.
