Today, Indian Corona patients have become the most in World, which is a very worrying situation, for us, it is a matter of satisfaction to reduce the death rate, due to which we have stopped fearing it today, but this situation can never turn in the absence of treatment. An agency of the World Health Organization on fast-spreading corona infection acknowledged that airborne transmission of coronaviruses could pose a threat in indoor locations. The World Health Organization has finally accepted that there is evidence of coronavirus infection ‘spreading through the air’. Scientists at the agency said in a news briefing that the possibility of airborne transmission cannot be ruled out, especially in crowded, closed, poorly ventilated settings. According to the agency, “proper ventilation” is essential for indoor environments.
In an open letter to the Journal of Clinical Infectious Diseases, 239 scientists from 32 countries have given evidence that it is a ‘floating virus’ that can stay in the air and infect people when inhaled. If an infected patient is kept in a closed place for a long time, then the coronavirus will be present in that place too, and any corona can be infected by coming in contact with that air. The World Health Organization has assumed that small droplets from the infected person’s sneezing and coughing remain in the air for a long time and that others are at risk of infection, so everyone needs to be cautious of air circulation
CSIR Chief Shekhar C. Mande of India has also expressed his views on all these concerns in his blog and quoted various studies and analyzes that all the evidence that has come out shows that corona is also spread by air. He said that it is clear that when people sneeze or cough, droplets come out of the air. Big drops fall to the ground but small drops float in the air for a long time. Large drops from an infected person’s sneezing or coughing fall on the ground and it does not go very far. But small droplets are present in the air for a long time. These small droplets are like aerosols.
Aerosols are particles suspended in the air that can form from dust, mist, or smoke. In terms of virus transmission, aerosols are smaller (5 μm or less) than breath drops, at normal indoor air velocities, a 5 μm droplet measures ten meters from a typical room-scale. Is too much. These remain suspended in the air for a long time, a person who is corona positive is likely to infect people standing even 1-2 meters away in small poorly ventilated rooms. People living in such environments can potentially infect these viruses in one another, resulting in infection and disease. That is why the Kovid-19 infection-causing respiratory drops have forced us to wear masks, keep distance, and adopt a routine of handwashing since the onset of the epidemic.
The difference between a droplet and an aerosol can be inferred by viewing drops and aerosols as droplets. The drops coming from a sick person’s mouth or nose are heavy and can fall to the ground before moving more than six feet. That is why we are insisting to maintain a distance of more than 1.5 meters between each other to avoid corona. Much smaller aerosols can travel longer before landing. Aerosol can be imagined to be somewhat like a drunkard who walks on a poorly lit street at night until he is taken off the road.
In the same way, small droplets and particles (diameter <5 μm – 10 μm) can be kept suspended in the air indefinitely, unless they are carried away by a light air or ventilation airflow. It can be a wall, furniture, or a person’s body that can thus successfully infect people. The lifetime of the virus that falls on a surface can range anywhere from a few minutes to a few hours. In a recent study, it was found that the most infected area was a 1-meter-square mobile toilet in the inpatient area. It has also been found that the risk is highest in air-conditioned rooms, especially cabins or cage-like rooms.
Spacious ventilated rooms, on the other hand, carry less risk of transmission. This means that an outdoor vegetable market is safer than a supermarket and a supermarket is safer than a small department store; however, it is believed that people maintain the norms of physical balance. So if you are indoors, open the windows to ensure maximum ventilation. Airborne transmission of coronaviruses is potentially a concern, which means that the virus can usually travel or spread in the absence of close contact.
It also increases the possibility that the virus can travel on air currents, and may even be transmitted through air conditioning. This means that social distance may not always be effective and the coronavirus can be a major threat, especially in crowded indoor areas with low ventilation. The World Health Organization is currently working on this matter more closely with scientists from different countries around the world and is trying to gather information about which another place where the coronavirus through the air Can spread. Well, so far we have not got the right information about the birth, spread, and end of the corona. Therefore caution is the only defense.
