Is Coronavirus Airborne? What Researchers Say? Online News Website Report
While most of
are safely enclosed within our home, some people do not have the luxury to stay
inside. Right now, all we can do is to maintain extreme hygiene and follow all
safety protocols. Above all- you must have all the information about it.

How long
coronavirus lasts on a surface.
Covid-19 or
coronavirus can last up to several hours or even days, founded by researchers
at the National Institute of Health, and the University of California. The
virus was exposed to various material, like plastic and stainless steel. The
virus remained active up to 24 hours on cardboard and up to 2-3 days on plastic
or stainless steel. The virus also remains stable in aerosols for around three
hours.
So, does that
makes the virus airborne?
The researchers
warn that the work conducted inside a lab may reflect differences in the
outside world as reading transmission dynamics amidst an epidemic is extremely
difficult. How the virus reacts in the wild is still unknown.
The researchers
put the virus into a nebulizer and puffed into a rotating drum for making it
stay airborne. The survival rate of the virus inside the drum will more likely
to differ if they sample the air around infected people. Neeltje van Doremalen,
Researcher at the NIH, says that the virus can’t be categorized as airborne, as
there is no evidence of aerosol transmission.
Finer aerosol
can stay suspended in the air for a long time, but larger droplets are more
likely to fall. When a person coughs or sneezes, the infection typically spread
through fluid droplets. The result may suggest that the virus stay alive in the
air, but there is no evidence that the infected person is producing a
significant amount of aerosols compare to droplets.
Joseph Allen,
Harvard’s professor for public health says that people must follow practical
precautions to airborne spread like staying in the fresh air and ensuring good
ventilation. Meanwhile, CDC officials say that contaminated surfaces do not
serve as an intense medium of transmission compared to person-to-person spread
through droplets.
Dylan Morris, a
researcher at Princeton believes there are additional factors to consider due
to the rapid spread of the virus.
Researchers are
planning to consider the effect of environmental conditions like temperature
and humidity on the virus.
In a recently
published data by Researchers on Wuhan based on aerosols gathered from
hospitals and areas around the region. While the air was clear in most part and
the Intensive care unit were also tested virus-free, but a large concentration
of aerosols was found in the staff area and a mobile toilet for patients. Some
researchers argue that toilet flushes may have sent some viruses to the air,
but the research is still early. Morris says, there is no evidence of aerosol
transmission of SARS-COV-2, but it may likely to exist in hospital settings.
