Recent reports said that COVID-19 can spread beyond 6 feet. This is the opposite of what has been known before which stated that the infection is less likely to be inhaled on distances farther than 6 feet.
A recent The Siasat Daily report said that when an infectious person breathes out virus indoors for an extended period of time of roughly longer than 15 minutes, and in some circumstances, hours, it can result in virus concentrations in the air space.
As part of its guidelines on COVID-19, the Centers for Disease Control and Prevention's latest science brief specified that while droplets settle out of the air within a few seconds to minutes, very fine droplets can stay suspended in the air for minutes up to hours. Such droplets are carrying viruses and transmitting infections, the brief also specified.

People typically release respiratory fluids while exhaling as they do quiet breathing, singing, speaking, coughing, exercise and sneezing in the form of droplets.
Exposure to Respiratory Droplets and Aerosol Particles
Also, according to the CDC, exposure to very fine respiratory droplets and aerosol particles and known respiratory fluids which are present in the air carry viruses that are the primary reasons for contracting the virus.
People typically release respiratory fluids while exhaling as they do quiet breathing, singing, speaking, coughing, exercise and sneezing in the form of droplets.
Exposure to such droplets takes place in three principal ways: first is through inhaling very fine respiratory fluids, depositing respiratory droplets on exposed mucus membranes in the mouth, eye or nose through direct sprays and splashes, and touching mucus membranes using hands that have been stained either directly by respiratory fluids that contain a virus, or indirectly by touching a surface that has the virus on them.
Virus Transmission Beyond 6 Feet
Further, the CDC explained that the risk of COVID-19 infection varies depending on the amount of virus to which an individual is exposed.
It can be adequate to transfer infections to people more than six feet apart and in some circumstances, to those who have passed through that space soon after the infections disappeared. The danger in this circumstance is more on enclosed areas with insufficient ventilation, elaborated the CDC.
While there stay remain a lot of knowledge gaps about COVID-19, the available evidence keeps on demonstrating that existing recommendations to prevent COVID-19 transmission stay effective.
Such recommendations include physical distancing, public use of well-fitting face coverings, avoiding crowded indoor areas and events, and adequate ventilation.
The CDC also suggested that the methods will lessen transmission from both breathing in of virus and deposition of the virus on exposed mucus membranes.
Transmission by means of soiled hands and surfaces, the agency suggested, can be avoided by regular practice of good hand hygiene and "by environmental cleaning."
Airborne
Since the onset of the pandemic in 2020, scientists have argued that COVID-19 was not airborne. But now, this outlook has been changing.
In a brief, the World Health Organization said, existing evidence proposes that the infection is spreading mainly between individuals who are in close contact with each other, usually within a short one-meter range.
An individual can be infected when droplets or aerosols containing the virus are breathed in or come directly into contact with the mouth, nose or eyes.
Last month, NDTV reported that the Lancet claimed in a new assessment that there is constant, strong evidence that proves COVID-19 infection is predominantly spread through the air.
