Researcher Naga Lee said that a Micro Particle can remain in the air for hours and days. It depends on the route of movement of the air.
Symbolic picture
There is no doubt that the most prominent weapon in the battle with Corona is the face mask. Even after the introduction of the vaccine (Vaccine), we do not have to leave the mask with us. Properly constructed multi-layered mask (Mask) prevents 84 percent of the particles from the person wearing it. At the same time, two people wearing such a mask can reduce the spread of infection by about 96 percent. This is revealed in a new research.
Experts, including scientists from the Georgia Institute of Technology of the US, said that the material used in making the mask, its tightness and the layers used in it can affect the spread of Novel Corona virus infection. In the research published in the journal Aerosol Science and Technology, the effect of the release of very small particles from various substances was studied.
‘Particle’ stays in the air for many days
The researcher Naga Lee said that a microscopic particle can remain in the air for hours and days. It depends on the path of movement of air, so if there is not proper system of air drainage in a room, then these small particles can stay for a very long time.
The scientists tested 33 different commercially available materials in their research, including one-layer woven fabrics such as cotton and polyester. He said that we came to know that different results of the release of elements from the same substance also came to light.
World returning to lockdown?
Although the vaccination campaign has started in most countries of the world after the introduction of the vaccine, but the havoc of Corona has not stopped yet. Due to the ever increasing cases, Bangladesh announced the lockdown on Saturday. European countries are also returning to lockdown to control corona proliferation.
Italy has announced a three-day strict nationwide lockdown to avoid a crowded situation on Easter. At the same time, Bangladesh has become the first Asian country, which has decided to lockdown the country due to the increasing cases of Corona. There will be a lockdown in the entire country for seven days from Monday. On Wednesday, France also announced a four-week lockdown. President Emmanuel Macron ordered the lockdown saying that the schools should be closed for at least three weeks.
