New findings suggest that it is possible for novel coronavirus to spread through air, as an airborn aerosol, especially in hospitals. What do you think?

Studies carried out to date indicate that the virus that causes Covid-19 disease is transmitted primarily through contact with respiratory droplets rather than through the air.

The World Health Organization still states that COVID-19 spreads mostly through direct contact with infected people and with infected large respiratory droplets, which measure more than 0.0002 inches in diameter. The hefty droplets fly from a person's mouth when they cough or sneeze, falling to the ground by the time they’ve traveled only a few feet.
However, mounting evidence suggests that aerosols may spur transmission more than once thought, and these smaller particles "can remain aloft for a considerable amount of time," on the order of hours, said Jeffrey Shaman, an epidemiologist and head of the Climate and Health Program at Columbia University in New York City.

There is a high likelihood that this can happen. However, this depends on the how far the virus can travel to the target's membranes. It is also dependent on surfaces that the virus appends on, how long the pathogen can survive on them and the WASH standards at health/patients/people handling facilities.
I read literature, my opinion is yes !
COVID-19 can spread through air and aerosol.
Why self isolation ?
That is the keypoint but, nobody know today.... https://hub.jhu.edu/2020/03/20/sars-cov-2-survive-on-surfaces/?fbclid=IwAR1TKl16ZeHLp-yNQAvo-qjKkqu31uHPz97FFWj6q7mJ7rSo2sf25LHVHiI
It may. There may be a couple of parameters that can support this theory but I will write an article on this issue and will post it here...
The number of infected people tells us it may be more than just a ''touch by touch'' method. Unless everybody was not coughing and sneezing at people's faces or on food items, there must be a higher airborne transmission distance achieved beside those meter or two suggested. We also need to have a laboratory-confirmed and exact size/weight ratio of a virus.
SARS-CoV-2 can be detected in the air up to 4 meters from COVID-19 patients
A recent study from Wuhan China indicates that SARS-CoV-2 virus is widely distributed on floors, computer mice, trash cans, and sickbed handrails and can be detected in air ≈4 meters from COVID-19 patients.

Dr. Muhammad Yousouf thanks. It comes into the rules of modus I am working on. You saved me a lot of effort and time. People do forget that objects heavier then air can fly or be carried away by the ''wind streams''. And ''winds'' are formed in many ways. The only thing left is the determination of a minimum quantity of infectious dose needed for an ''average healthy'' or ''average sick'' person to get infected by breathing in a virus as ''breathing in'' is our biggest concern besides the ''touch'' we all are aware of. We understood a long time ago that contact is a primary reason for infections. Our concern for SARS-CoV-2 is negligence toward possible infection at the distances beyond recommended as secure as well as the possible inhalation of the virus at the distance ''they'' found to be safe or impossible to be infected at.
Dear Mr. Sekulovic! This new virus is an enemy we have to gain new information about all the time. The spreading process is one of the most important:

It is most likely that this virus is mutant and will become more dangerous in the long run. The second and third wave in Europe and USA are going to hit within a year: YLE (2020).

One peculiar characteristic of the novel coronavirus is that infected people shed large quantities of the virus early on when symptoms first appear or even right before the onset of symptoms.""

Respiratory infections can be transmitted through droplets of different ... Implications of recent findings of detection of COVID-19 virus from air sampling ... of the COVID-19 virus.10 In this experimental study, aerosols were ..
It is a widely accepted view that COVID 19 is either transmitted via surface contamination or via close contact of an uninfected person with an infected person. Surface contamination usually happens when infected water droplets from exhalation/sneeze/cough of COVID sick person settle on nearby surfaces. COVID 19 coronavirus can also be airborne in a puff cloud loaded with infected droplets generated by COVID sick people.
Source: Preprint On the airborne aspect of COVID-19 coronovirus
COVID 19 virus is not transmitted by air, rather it is transmitted between people through close contact, being infected by droplets given out when an infected person sneezes or coughs. However, scientists have reported that spread of COVID 19 disease appeared to be occurring through airborne transmission of aerosols produced by asymptomatic and symptomatic individuals produced during breathing and speaking. It is thought that these aerosols can remain infectious in indoor air for some hours and can be inhaled to get infected.
Transmitted usually through close contact and Very rarely through air
Is this a proof:

I am sure human droplets containing Covid 19 material can vaporize carrying it in an indoors and infecting others. Water, which is in big percentage a part of droplet vaporize even at 0 degrees centigrade, but very slowly. The warmer - the faster. What pushes up the vapors additionally is the difference in the atmospheric pressure that is caused by the difference in temperature and moisture, similar to tornados. So, in indoor premises, the mixture of the inner heat and outside cold or vice versa will influence micro tornados lifting vaporized droplets with COVID -SARS22 by the simple opening of the doors or windows picking it up from the floor and into the air, containing still an active virus pathogens, thus people inhaling it. If it is in the hospital when there is an enormous production of it, it will be carried in an enormous airborne quantities. Figured it out long time ago .I used to fly a paraglider and trust me - thermal air can lift heavy objects...
Just to add to former answer, it is more the pressure difference that causes the thermals. Water tends to equalize with surrounding pressure very fast thus becoming a fume, again depending on the pressure difference. Water can boil at room temperature on 30 000 feet - 12 km. Coughing, talking and sneezing will in certain conditions, this is my opinion, carry a virus at further distance then a meter or a two. What i have set as a problem are a vaporized micro droplets being ''cooked'' by the pressure and temperature difference thus being lifted in the air from the floor and inhaled. That is why I believe they were found, at a reference above, for extended time at the indoors . At the outdoors too, but they will be dispersed quite easy and not in such quantities that are hazardous to infect. And of course impossible to catch and prove their presence.
