Face shield, plexiglass barriers are 'a waste of money' in Covid-19 battle: US aerosol expert

https://str.sg/wMEtMANILA (PHILIPPINE DAILY INQUIRER/ASIA NEWS NETWORK) - Instead of face shields and plexiglass barriers, the Philippines should rely more on protective masks and proper ventilation, and even going outdoors, an American aerosol expert said.

Professor Jose-Luis Jimenez of the University of Colorado-Boulder said the government should buy more N95 masks for the country's health care and other essential workers as well as people with a weak immune system.Medical workers should also wear laboratory goggles to suppress air filled with virus from getting close to the eyes, rather than plastic face shields, which Prof Jimenez described as a"waste of money, time and attention create basically plastic pollution".

sg/wMEt MANILA (PHILIPPINE DAILY INQUIRER/ASIA NEWS NETWORK) - Instead of face shields and plexiglass barriers, the Philippines should rely more on protective masks and proper ventilation, and even going outdoors, an American aerosol expert said. Professor Jose-Luis Jimenez of the University of Colorado-Boulder said the government should buy more N95 masks for the country's health care and other essential workers as well as people with a weak immune system. “Make sure you are fully vaccinated before travelling to Singapore,” the updated notice said on the CDC website . Medical workers should also wear laboratory goggles to suppress air filled with virus from getting close to the eyes, rather than plastic face shields, which Prof Jimenez described as a"waste of money, time and attention create basically plastic pollution".S. He said in an e-mail to the Inquirer:"Now that we know that the virus is airborne and that it can infect through the eyes, is actually not sufficient because the air, like a smoke on the aerosols, can flow under the face shields.” According to the CDC website, Level 3 countries have a COVID-19 incidence rate of between 100 and 500 new cases over the past 28 days per 100,000 population." Prof Jimenez is a professor at the university's Department of Chemistry and Biochemistry (Analytical, Environmental and Atmospheric Chemistry Division), and a fellow of the Cooperative Institute for Research in the Environmental Sciences. The United States is facing a surge in infections caused by the highly contagious Omicron variant and on Monday had 132,646 people hospitalised with Covid, surpassing the record of 132,051 set in January 2021.

The Philippines government has made face shields voluntary but may consider their required use amid the surge in coronavirus cases being attributed to the spread of the Omicron variant. On Jan 4, the CDC said that the level of COVID-19 in Singapore was"unknown"., and Wisconsin have reported record levels of hospitalized Covid-19 patients recently, according to the Reuters analysis. "So, in summary, the face shields are not useful at all," Prof Jimenez said, as he called for the distribution of more N95 masks to people who cannot afford them. He said these masks can be worn for about 40 hours, which would not require constant changing. On Jan 5, Health Minister Ong Ye Kung said that this classification was applied because the US CDC was "not aware of our surveillance test numbers", and that Singapore was providing it with the data. "The government could also consider setting up a domestic manufacturing capability for N95 masks, so that the supply is available for later Covid[-19] waves the next pandemic," said Prof Jimenez, whose areas of expertise include aerosols, atmospheric chemistry, aircraft studies, instrument development, mathematical modelling, and disease transmission. The United States has averaged over a half a million cases for the last six consecutive days, according to a Reuters tally. The Spanish-American chemist drew the attention of Filipino netizens after he included the Philippines in a post on Twitter on what he described as the"world hall of shame" - countries that he said have bad practices in managing the Covid-19 pandemic. "If a destination does not provide data, their travel health notice level is designated as 'unknown' and travellers are advised to follow travel health notice Level 4 recommendations," the CDC said. Since the Covid-19 pandemic, China and the United States have sparred over air services.

Prof Jimenez had pointed out, for example, the use of motorcycle barriers which the government approved but later dropped, and also the installation of plexiglass barriers in classrooms and offices which, he said,"should be removed because they increase the transmission". He said:"I don't think those shields really do anything and…frankly, they are pretty ridiculous. "Just to be clear, we know our situation very well," Mr Ong said during a COVID-19 multi-ministry task force press conference.C." Lately he noted how hospital ventilation in the country is"not known to be quite good". He provoked criticism from a medical adviser to the government, former health undersecretary Teodoro Herbosa, who said on Sunday (Jan 9) that Prof Jimenez had"no expertise on disease epidemiology and pathogenesis". And that works out to over 21,000 PCR tests per day. But Prof Jimenez stood by his recommendations to avoid or lessen the circulation of the coronavirus. REUTERS Related topics." A long-standing US-China air agreement allows the countries to operate over 100 weekly flights between the two nations but only a fraction of those are currently operating.

He said taxi drivers should consider opening their windows to prevent any infection between them and their passengers." There are also 145 wastewater testing stations across Singapore in places like housing estates, dormitories and nursing homes, he said. He also suggested that encouraging people to go outside would help prevent transmission indoors, especially in enclosed spaces. More On This Topic .
