As India witnesses an unprecedented and fierce rise in the number of people infected with Covid 19, hospitals flooded and crematoriums are now operating at full capacity amid an acute shortage of oxygen supplies, the Indian government recommended that 1.4 billion people wear masks even indoors.
The head of the task force concerned with confronting the Corona virus in India, Dr. Vinod Kumar Ball, said yesterday, Monday, that “the time has come for us to start wearing the muzzle at home even if there are no injuries to one of the family members,” at a time when 352 thousand and 991 were recorded. New infections and 2812 deaths within 24 hours.
Paul added in a press conference yesterday, Monday: “If there is a positive case of Corona in any family, it is very important for the patient to wear a mask (muzzle) even inside the house because he can transmit the infection to the rest of the individuals.”
The virus that causes Covid 19 disease is transmitted mainly through respiratory droplets, which spread in the air when a person coughs, sneezes, speaks, shouts or sings. These droplets can then land in the mouths or noses of nearby people, or be inhaled.
The dangerous thing is that symptoms do not appear in a large number of people; So people without symptoms can continue to spread the infection at home at a faster rate.
Dr. Paul warned that asymptomatic people could spread the infection to others by simply “talking”. This explains why entire families in India were injured in this fierce wave, despite their commitment to stay indoors, according to the Indian Express newspaper.
But why in the second wave specifically?
A large proportion of the at-risk population in India developed severe symptoms including shortness of breath, and many required hospital treatment. The extremely high requirement for oxygen beds has overwhelmed Indias health infrastructure.
The masks (masks) mainly aim to protect others from Corona (Covid 19) and not lose the wearer. Therefore, the Indian government’s recommendation is not only aimed at curbing transmission, but also at protecting the most vulnerable.
According to the “Indian Express”, there are two conclusions that can be reached by achieving this recommendation: The first is to greatly protect the elderly and those with chronic diseases, even if a family member has an asymptomatic infection. The second is to limit the spread of the virus among families, which distinguishes this wave from its predecessor in India.
Was the Indian recommendation based on any global health guidelines?
Yes, the Indian government cited data from the North Carolina Department of Health and Human Services, which stated that there was a small risk of transmission at a distance of 6 feet between two people even if they were wearing a muzzle.
According to the mentioned data, the risk is 1.5 percent (low) when both people wear masks, 5 percent (average) when the affected person only wears a mask, 30 percent (high) if the affected person does not wear a mask and their contacts wear it, and 90 percent (very high) When an injured or uninfected person does not wear a mask.
Last December, the World Health Organization recommended wearing masks at home to prevent infection with a virus when receiving visitors, if it was not possible to maintain physical spacing between attendees. The recommendation included wearing masks indoors when it is not clear if the room is being properly ventilated.
Were similar recommendations issued in other countries?
The U.S. Centers for Disease Control and Protection (CDC) made nearly the same recommendation. She said that you should continue to wear the muzzle in addition to at least 6 feet away from each other, especially when you are indoors with strangers.
The American Center stressed the need for elderly people, in particular, to wear masks when they are near people who do not live with them in their homes. This means that if a person is hosted at home, the most vulnerable groups need to wear a mask to reduce the risk of transmission.
Has any other study shown benefits of wearing a muzzle indoors?
Yeah. A study conducted on Chinese families in Beijing before it was published in the British Medical Journal found that wearing a muzzle inside the home is 79 percent effective in reducing transmission – but only before symptoms appear, according to the Indian Express.
The study, which included 335 people within 124 families in Beijing, found that the risk of transmission at home was 18 times higher with frequent daily close contact with the infected case, and that wearing a muzzle by the case and those close to it from family members – before the initial symptoms appeared – was 79 percent effective. Percent in reducing transmission. However, wearing a muzzle after the onset of the disease was not very protective.
The results of that study indicated the need for “the global use of masks and the commitment to social distancing, not only in public places, but inside homes among family members at risk of injury,” which supports the comprehensive use of masks, and also provides guidelines to reduce the risk of injury to families who live with someone An isolated patient or in quarantine, and the families of health workers who may face ongoing risks.
