Jakarta, CNBC Indonesia – Research by Japanese researchers reveals surprising conditions about masks. Masks cannot make users 100% free from the risk of being infected with the Covid-19 corona virus which spreads in the air (airborne).
In this test scientists from the University of Tokyo placed two mannequins facing each other in a room. One mannequin head is equipped with a nebulizer, a cough simulation device using actual coronavirus particles. Others mimic natural breathing, where the virus enters through the respiratory tract.
As a result, cotton masks can block the virus by up to 40% compared to not using a mask. The surgical mask is able to block transmission of more than 50%.
N95 masks, which are used by medical professionals, are able to block the virus by up to 90%. The results of this study indicate that the N95 mask, which is considered the safest, still has the potential for users to be infected with the Covid-19 virus.
“There is a synergistic effect when the recipient of the virus and the spreader of the virus wears a mask,” wrote the University of Tokyo researchers, as quoted by Reuters, Thursday (22/10/2020).
There is a growing consensus among health experts that the Covid-19 virus can spread through the air. This month, the US Centers for Disease Control and Prevention (CDC) revised its guidelines and said pathogens can stay in the air for hours.
A separate Japanese research team used supercomputer simulations to show that humidity could have a significant effect on the spread of virus particles in the air.

Merdeka.com – Director of the United States Center for Disease Control and Prevention (CDC) Robert Redfield said, using a mask can protect individuals against the Covid-19 corona virus more than just a vaccine.
At the Senate Appropriations subcommittee hearing, Redfield said face masks were “the most important and powerful tool of public health” and the United States could control the pandemic if all individuals wore masks for 6 to 12 weeks.
“I might even go so far as to say that this face mask is more guaranteed to protect me from Covid-19 than it was when I took the vaccine, because the immunogenicity is probably 70 percent and if I don’t get an immune response it won’t protect me,” explained Redfield. .
“These face masks will protect me, we have clear scientific evidence they work,” he added, as quoted by the office news Anadolu Agency, Thursday (17/9).
Redfield said a vaccine may be available in November or December but will not be widely accessible until the second or third quarter of 2021.
Masks are mandatory in some states, and experts believe wearing masks is essential to slow the spread of the disease.

This will also depend on the size of the car. For a car that is large and spacious enough, it doesn’t matter if it is filled with three passengers. As for small cars, it is recommended that a maximum of two people be filled.
On the same occasion, Erlang also recommends that you use a three-layer cloth mask. “Not recommended [menggunakan masker] scuba. The pores are large, the protection is small, only 0-5 percent, only one layer, “he said.
DKI Jakarta has again imposed large-scale social restrictions (PSBB) since Monday (14/9). People are advised not to leave the house, except for urgent needs. Even if they leave the house, people are advised to comply with health protocols such as wearing masks, maintaining physical distance, and washing hands.

However, if someone is driving alone in a car, is it still necessary to wear a mask? Is there a risk of Corona transmission when alone in the car?
According to a pulmonologist from Friendship Hospital, Dr. Erlang Samoedro, SpP, the risk of contracting Corona when alone in a car is fairly small. Dr. Erlang emphasized that as long as no one else is around it means safe from exposure.
“Exposure to the virus from people, so if there are no other people, there is no exposure. So it is safe if there are no other people,” said Dr. Erlang when contacted. detikcom Thursday (17/9/2020).
Dr. Erlang explained that the display of the Corona virus from someone should be avoided. “The important thing is the exposure of the person so that the person is avoided,” continued Dr. Erlang.

HENDERSON, KOMPAS.com – A Nevada company campaigning for Donald Trump inside an enclosed space, was charged fine 3.000 dollar AS (Rp.44.5 million), for violating domestic protocols regarding the corona virus.
The campaign, which was attended by thousands of people, took place on Sunday (13/9/2020) and used the facilities of Xtreme Manufacturing in Henderson, Nevada, has violated state restrictions for gatherings of 50 people or more.
The city of Henderson has warned Xtreme Manufacturing that it will break the rules, if the campaign continues.

Richards added that the company “has 30 calendar days to respond to the notification and pay a fine or dispute the notification of infringement.”
The indoor event occurs when death results Covid-19 close to 200,000 nationwide.
Previously, a similar indoor Trump campaign was held in Tulsa, Oklahoma, in June, which saw a spike in coronavirus cases in the city, as well as multiple diagnoses among Trump campaign staff and Secret Service agents.
When asked generally about the Trump campaign in Nevada, and whether it would limit the number of participants, Trump’s campaign team on Saturday offered only a vague explanation of the protocol to be followed.
Ahern, who owns a Las Vegas hotel and equipment rental business apart from Xtreme, said he considered the campaign “no different from the thousands of people allowed to gather at gaming tables, pool parties without masks and protests across the street”.
He also noted that he was not disillusioned by the city workers who provided him with a violation notification.
“You know, they have work to do. They might be directed. So we respect everyone’s position in this situation,” Ahern said.
Hotel Ahern in Las Vegas was fined after hosting an “Evangelicals for Trump” campaign in August that exceeded state boundary rules and also violated several city health restrictions.
KOMPAS.com – A recent study from the United States Centers for Disease Control and Prevention (CDC) found that transmission is possible Covid-19 while eating at restaurant.
Reported ABC News, the study examined exposure to close contact that contributes to the spread of the virus.
As a result, it found that adults who tested positive for Covid-19 were twice as likely to report it eat at the restaurant within 14 days before being declared infected, compared with those who tested negative.
Dr Kiva Fisher, lead author of the study, which looked at symptomatic outpatients from 11 US health care facilities, said that activities made it difficult to put on face mask and maintaining social distancing, such as eating at restaurants, may be a risk factor for Covid-19.
Fisher advises that customers and restaurant staff implement protective measures to reduce potential exposure COVID-19 during eating and drinking in restaurants.
These steps include:
Encourage sick staff to stay home
Require staff to wash their hands frequently
Require the use of masks, and
Offers service options delivery
“It is also important for customers to take precautions when eating outside the home, such as wearing a mask when not eating or drinking, being at least two meters away from other people and washing their hands frequently,” said Fisher.
BETWEEN PHOTOS / REUTERS / Mike Blake / foc / djo Some people wear masks while walking on the pier, amid the coronavirus (COVID-19) pandemic in Oceanside, California, United States, Monday (6/22/2020).
Reported CNN International, a study published on Thursday (09/10/2020) included data on 314 adults with symptoms of Covid-19 in July.
Of the 314 people, 154 tested positive and 160 tested negative.
The tests were conducted at 11 different health care facilities in 10 US states: California, Colorado, Maryland, Massachusetts, Minnesota, North Carolina, Ohio, Tennessee, Utah and Washington.
Researchers from the CDC and other institutions looked at how patients responded to questions about wearing masks, and various activities in the community, including whether they recently ate at restaurants, hung out at bars or went to the gym.
As a result, 42 percent of adults who tested positive reported having close contact with at least one person known to have Covid-19.
Meanwhile, most of the close contacts, namely 51 percent, were family members.
The researchers also found that 71 percent of people who tested positive for Covid-19 and 74 percent of those who tested negative always used a mask when in public.
There was no significant difference between those who tested positive and negative while doing shopping, hanging out with less than 10 people at home, going to the office, going to the gym, going to the salon, using public transportation or attending religious gatherings.
However, people who tested positive were more likely to report eat in a restaurant in the two weeks before they start feeling sick.
Of note, this study has several limitations, including that more research is needed to determine whether similar findings will emerge among a larger group of patients, and questions about restaurant differences. indoor or outdoor.
“Reports of exposure in restaurants have been linked to air circulation. Direction, ventilation, and intensity of airflow can influence virus transmission, even if social distancing restrictions and use of masks are implemented according to current guidelines,” the researchers wrote.
” Face mask cannot be worn effectively while eating and drinking, whereas shopping and many other indoor activities do not preclude the use of masks, “write the researchers.
