The issue of the possibility of an outbreak of coronavirus has generated widespread controversy as cases continue to rise in the United States and health officials are scrambling to issue guidelines that will keep people safe without completely closing life and activities.
It is now known that people can become infected with the Coronavirus when the infected person coughs or sneezes, and spreads drops of saliva and mucus, which others can inhale.
But a new study from the University of Nebraska indicates that what many scientists fear may be true, as the virus can be transmitted in fine aerosols that leave the mouth and nose when people talk or breathe normally.
The researchers found, in air samples from Corona’s patients’ rooms, that the virus in these samples could be duplicated in Petri dishes in the laboratory, according to a research paper published on MedRxiv.org, but has not yet been reviewed by peer researchers.
If breathing and speaking can spread the virus in fine fog (known as aerosols), it will likely remain in the air and travel much farther than the six-foot (1.8 m) distance and people are currently advised to adhere to it.
And he knows that the air in hospitals, our homes, grocery stores, shopping malls and even abroad, does not consist only of oxygen, nitrogen and carbon dioxide, but rather dozens of particles, gases and water vapor.
The air also joins with billions of viruses, which blow into the breeze, but most of them cannot infect humans and pose no threat.
Viruses are small, even smaller than bacteria, but most of those that infect humans need protection in relatively large droplets of fluid, such as those that we cough or sneeze, in order to survive, and these heavy droplets fall to the ground or appear on the surface relatively quickly, reducing From the possibility of inhaling it. Viruses that persist in the aerosol can travel more and remain suspended in the air for a longer period.
The University of Nebraska team tested whether aerosols from the corona virus patient’s rooms could contain a virus by transferring samples to cell cultures in laboratory petri dishes, and in five of 18 according to SARS-CoV-2 scientists, the virus that causes “Covid-19” disease, begins to multiply.
This indicates that the virus cannot be transmitted only in the aerosol, but rather that it remains in the air to be infectious, and an increasing number of experts have begun to believe that the airborne transmission plays a role in the spread of the Corona virus.
The chief communicable disease expert in the United States, Dr. Anthony Fossey, said that there is not enough evidence to prove that this is the case, but it cannot be excluded either.
Even the World Health Organization (WHO) recently recognized that air transport is possible.
And if the peer review validates the results of the University of Nebraska study, then this will be further evidence that the risk of coronavirus infection can spread anywhere the person was infected, and for a longer period of time than previously thought.
This would emphasize the need for people to wear masks at all times in public places.
