New Delhi, March 6 (IANS) While buying a new face mask to protect yourself from Covid-19 infections, be sure to go for a three-dimensional mask as it is more effective than single or double-sided options. complex, health experts stressed on Saturday.
According to experts, additional layers in the mask may help us protect against SARS-CoV-2 by not allowing the infected droplets to become fully infected or fragments. through the mask.
“Covid-19 is spread mainly through respiratory droplets produced when someone who has contracted the virus through coughs, sneezes etc,” Navneet Sood, Pulmonary Consultant, Dharamshila Narayana Superspeciality Hospital, said. to IANS.
“As we know that the layers of a mask help to increase its seeding power, it is vital that it has a three-dimensional mask, so that we can protect ourselves from becoming infected or infected. infecting people around us, “said Sood.
A team of researchers, including Saptarshi Basu of the Indian Institute of Science, Bengaluru and Abhishek Saha from the University of California – San Diego have shown, in a study, that three-dimensional surgical masks are most effective in preventing on large drops from coughing or sneezing from getting atomized to smaller drops.
These cough drops can pass through the masks with single or double layers and atomize into much smaller drops, which is especially crucial as these small drops (often called aerosol) are able to stay in the air for longer times.
“While it is expected that large solid particles in the 500-600-micron range should be stopped with a single-layer mask with an average pore size of 30 microns, we show that this is not true for melt droplets,” he said. Saha.
“If these respiratory droplets have enough distance, which happens for coughing or sneezing, when they land on one layer of this substance it will disperse and push it through the smallest pores in the mask,” he said.
For the study, published in the journal Science Advances, the team used a droplet generator and a high-speed real-time camera.
According to the Centers for Disease Control and Prevention (CDC), when choosing a mask it should always go for masks – with two or more layers of washable, breathable clothing in, which completely covers your nose and mouth, which fits snugly against the sides of your face and there are no gaps.
“One should know that not all clothes make for an effective mask. Also, some clothes do not suit certain skin types and the way they are woven is a reason other, “said Shiba Kalyan Biswal, Consultant, Pulmonary and Sleep Medicine, Narayana Hospital, Gurugram.
“One should opt for masks with small pores as it may further protect against the virus by not helping drops or partners full of virus to pass through. After them buying them maintains the cleanliness is also a key feature, “Biswal said.
The health experts have also warned that we need to be more careful as cases of new Covid strains are gradually rising in the country.
They have revealed a number of capabilities that may be due to people’s lame attitude towards following Covid protocols or the appearance of “new mutations and sequences” causing the increase, as studied with the laboratories involved in Covid detection across the country. .
Various studies have reported that a variant of SARS-CoV-2 released in the UK – B.1.1.7 – in November 2020 is more mobile than previous modifications and will lead to a significant recovery of Covid-19 cases.
The Union Ministry of Health said Friday that 16,838 new cases of Covid-19 in the last day pushed the amount to 1,11,73,761, killing 113.
The Ministry also reported that 7,61,834 samples were confirmed on Thursday. The cumulative tests conducted by the Medical Examination Council of India (ICMR) to date stand at 21,99,40,742.
To date, 1,80,05,503 doses of corona vaccine have been administered in the country since the campaign began on 16 January following the approval of ‘Covishield’ and ‘Covaxin’.
