Tests show that COVID-19 can diffuse in the air

COVID-19 (New Coronavirus Infection) (# If there is no character limit, add parentheses when first appearing Not a pandemic.

However, it persistently circumvents personal protection and facility containment measures to infect medical staff. It threatens the ability of medical services to treat the general public.

In Victoria alone, 1600 healthcare workers have already been infected. The cause remains unknown.

Simulations were performed after the fear of SARS and swine flu repeatedly identified one overwhelmingly deadly feature, the ability of the virus to remain in the air.

The cough droplets settle on the surface quickly. However, smaller particles (called aerosols) can be created just by speaking. And these can stay in the air for hours.

The extent to which COVID-19 could do this was a matter of intense debate and research.

This is a new virus and belongs to a known family of viruses, the coronavirus, but it is not working as expected. Therefore, identifying its unique properties is an urgent task of research.

Now new research has added evidence that more research shows that COVID-19 does what everyone is most afraid of.

“I don’t know what it is unless it’s a smoking gun,” tweeted US aerosol scientist Lindsey Marr.

“Smoking Gun”

There was circumstantial evidence of viral spread that could be most easily explained by airborne transmission.

However, medicine, like most science, requires court-proven evidence.

In this case, the evidence needs to be carefully tested and recorded that small airborne droplets of water can carry live colonies of COVID-19.

These droplets vary in size, from the humidity of exhaled air to the droplets that protrude from a cough or sneeze.

From the beginning it was clear that a cough could infect the virus. This is behind the advice on the physical distance of 1.5 meters from others.

But Virologist has now discovered Live viruses remain in the hospital air.

“This is what people aspire to,” Ma told the New York Times. “There is clear evidence that there is an infectious virus in the aerosol.”

A University of Florida study collected air samples from the COVID-19 treatment ward in Florida. These were collected at a distance of 2-5m in infected patients.

Such collection is not easy. The virus should not be damaged. Also, the conditions must match the conditions for sending.

Ultimately, the sampler needed to simulate human inhalation.

Ward air was completely recycled every 10 minutes, fitted with medical-grade filters, UV light, and numerous protective screens surrounding the patient.

The researchers found a small amount: only 74 live virus particles per liter of sampled air.

It is not yet known if it is enough to infect anyone.

However, researchers believe it may suggest that viruses in the air may accumulate in poorly ventilated spaces and rooms.

Super diffusion threat

2018 Simulations performed by John Hopkins Center for Health Security Designed to test how governments, government agencies, and healthcare organizations responded to pandemics.

What are the main challenges? Identify if the virus was delivered sufficiently quickly by either cough (best case) or aerosol (worst case).

In a fictional scenario, they counteracted these people with moderately contagious viruses that were genetically engineered to fly into the air. It was too late when the nature of this threat was confirmed.

The virus was too widespread to be contained.

In that simulation, 150 million people died within the first 12 months.. The worst victims were healthcare workers.

Cause: A “super spreader” event where the virus moves quickly to a large number of new hosts. These events become more serious and deadly due to aerosol-borne diseases.

The COVID-19 has definitely proven to be a “super spreader”.

Meat processing facility. wedding. Call center. Nursing home. Explosive growth in crowded, damp, poorly ventilated spaces helped propel the virus around the world.

Studies show that 10 to 20% of patients with coronavirus can be infected with 80% of new infections. Other viruses such as influenza do not work this way.

Find out why it is the key to containing the disease.

Seattle Base Researcher at Fred Hutchinson Cancer Research Center Unfortunately, “super diffusion” turned out to be the convergence of events.

It needs a victim at the time they are shedding a large amount of virus.

It needs to be set up with many people available to get the virus.

We need an environment that encourages that movement.

Infected people are most infectious during the first to two days of the second week of infection. Unfortunately, some people at this peak have not experienced symptoms.

“We still don’t know how contagious the flu we’ve been studying for decades will be by touching aerosols and contaminated objects,” Ma told National Geographic.

The extent to which COVID-19 remains in the air Discussion and research issues..

It won’t be resolved soon.
