Scientists have known for several months that the new coronavirus can be discontinued in microdropts expelled through patients when they communicate and breathe, however, so far, there has been no evidence that these small debris is infectious.
This reinforces speculation that speech and breathing in general, not just coughing and sneezing, are to blame for the spread of COVID-19, and that infectious doses of the virus can exceed the recommended six feet (two meters) over social distance. Guidelines.
The effects are still initial and have not yet been published in a peer-reviewed journal, which would give more credibility to strategies developed through scientists.
The paper was published on the website medrxiv.org, where the maximum of state-of-the-art studies during the pandemic was made public for the first time.
The same team wrote an article in March showing that the virus remains suspended in the air in the rooms of patients hospitalized by COVID-19, and this will soon be published in a journal, according to the lead author.
“It’s pretty hard” to collect the samples, Joshua Santarpia, an associate professor at the University of Nebraska Medical Center, told AFP.
The team used a device of the length of a cell phone for this purpose, but “concentrations are very low, the chances of recovering the device are low”.
Scientists took air samples from the rooms of patients prostrate in bed, about 30 centimeters above the foot of the bed.
Patients spoke, generating microdroplets that were suspended in the air for several hours in what is a “spray”, and some coughed.
The team was able to collect microdrops as small as a micron in diameter. They then placed those samples in a crop to grow, and found that 3 of the 18 samples analyzed were capable of replicating.
For Santarpia, this is evidence that microdroplets, which are also far greater than giant droplets, are capable of infecting humans.
“It replicates in mobile culture and is infectious,” he said.
The possibility of coronavirus microdropdrop transmission at one time was considered unlikely through the government of fitness worldwide.
Later, scientists began to replace their minds and recognize that this may be just a possibility, which justifies universal masking.
The World Health Organization is among the last to replace its position on 7 July.
“I have a feeling that the debate has become more political than scientific,” Santarpia said. “I think most scientists working with infectious diseases agree that there’s probably a component in the air, we may wonder how big it is.”
Virginia Tech professor Linsey Marr, an expert in aerial transmission of viruses and not interested in the study, said it is rare to get measurements of the amount of viruses provided in the air.
“From what we know about other diseases and what we know so far about SARS-CoV-2, I think we can assume that if the virus is ‘aerosol-infective’, then we can mings in their breaths,” he said. Afp.
Stay home. Shut up. There’s no hope. It’s getting too much.
Still probably infectious when breathing it! With its incessant and unstoppable diffusion despite the locks, social distance and hygiene and everything that is thrown at him, I find it an insane thought. is more than “probably” infectious in this way
But I know! WHO experts can be trusted (the latter to admit that this may be an option on July 7, according to the article). Look at this to see how your experience with the virus also helped the previous global in the pandemic.
From the beginning, this has been as much as possible, but not the most likely route. Substitution is the option that this mechanism is important, nothing possible.
The effects are presented as more vital than they are, with enough effort and time, all other respiratory pathogens can be removed from aerosols and can also be infectious to cells, this does not mean that this is likely or frequent, that is what science is looking for. to examine right now.
A vital explanation is that mobile phones are much less difficult to infect than humans because they are completely exposed and do not have innate immunity points (things as undeniable as mucus, for example), so the effects of mobile culture cannot be directly extrapolated to human infection. Another vital thing is that the samples were collected at the minute, however, infections on mobiles are reported only through total collection, this is vital because it does not allow us to know if the aerosols are consistently infectious or not, because the knowledge is presented, it is quite imaginable that the viruses are only infectious during the first few minutes of Array and the rest of the time , its concentration is too low, dry or inactivated to be dangerous.
It’s bad research, however, it only reports things we already strongly suspected from epidemiological data, and not long ago to respond to what scientists are looking to locate right now.
After watching the stage of the m/v Diamond Princess on television, I became convinced that an airborne infection occurred. But it’s great that they tell you now anyway.
