Coronapocalaypse is an unprecedented catastrophe for which no country was prepared to counter. Countries are making efforts taking to stem the spread of coronavirus, one of the hands-on plans is setting up of anti-viral walk-through. CoronaVirus: Efficiency of Antiviral Walk-Through Gates According to the Experts.
Government is putting the best of it to secure public health through these sanitized passages would burden a lot on our already crumbling economy. Moreover, it is a huge investment and should be backed by scientific evidence. Likewise, People must not relinquish hand washing and social distancing if they walk through such gates, only Self-Guard halts the sickness.
CoronaVirus: Efficiency of Antiviral Walk-Through Gates According to the Experts
Talking to Dawn, Dr Shireen Khan, head of tuberculosis and chest diseases department at the Fatimah Jinnah Hospital in Quetta, said
“People need to remember that the virus inside your body does not die once you walk through these gates. These [walk-through gates] do not provide complete safety against the virus and there is no recommendation from the WHO in this regard.”
Dr Khan Strongly Stressed on to Upkeep the Basic
“A lot of people feel that these gates are safe because in films they show people walk in and out of labs after being sprayed”. What they are talking about is biosafety level 4 (BSL-4) — the highest level of biosafety precautions, and is appropriate for work with agents that could easily be aerosol-transmitted within the laboratory and cause severe to fatal disease in humans for which there are no available vaccines or treatments. In BSL-4 labs, personnel must pass through a chemical shower for decontamination, then a room for removing the positive-pressure suit, followed by a personal shower, according to safety guidelines.”
Dr Shobha Luxmi, infectious disease specialist and assistant professor at the Dow University of Health Sciences (DUHS) called it a “public joke”
“This is a latest joke being played on the public. This is a waste of money, sharing that someone offered to set up such a tunnel gate at the hospital and I refused the offer. The virus won’t die. It needs 30 seconds to disintegrate.”
Dr Mukhtiar Zaman, the head of pulmonology at the Rehman Medical College Peshawar
“Only clothes are sanitized, that too if a person walks through slowly. The basic rule is maintaining good hygiene and maintaining social distance. The chemical will cause allergic reaction and breathing issues.”
WHO Website, Clearly Presages the Myth of Spraying
“No. Spraying alcohol or chlorine all over your body will not kill viruses that have already entered your body. Spraying such substances can be harmful to clothes or mucous membranes (ie eyes, mouth). Be aware that both alcohol and chlorine can be useful to disinfect surfaces, but they need to be used under appropriate recommendations.”
The Medical Microbiology and Infectious Diseases Society of Pakistan (MMIDSP) said
“Covid-19 virus primarily infects cells in air sacs of the lungs (alveolar macrophages) but is capable of infecting many different cell types and organs in the body. It resides and multiplies within the cells; mature virus exits the cell, finds its way into respiratory secretions and is coughed out and transmission continues.”
MMIDSP president Dr Bushra Jamil of the Aga Khan University Hospital expressed her views
“Only an effective antiviral agent can be expected to block multiplication and spread of the virus. Such an antiviral for SARS CoV-2 has not been found yet. If there is any part of the human body which should be decontaminated to block transmission, it is the hands, which brings us back to ‘hand washing’.”
General perception of mainstream connoisseurs regarding anti-viral walk-through gates
“Important thing is use of mask by symptomatic individuals because virus is in secretions. Use of mask by symptomatic individual or asymptomatic infected individual can reduce transmission by blocking droplets. So combination of hand hygiene and universal use of masks (regular cloth mask would do) is effective. Given that 70 per cent alcohol for disinfection is expensive, many people are opting for spray solution that contains chlorine (household bleach). Use of bleach should be avoided in spray form. Fumigation should never be used on people. It is meant for inanimate objects and surfaces. Also the chemical damages eyes, skin, throat and lungs.”
A 2016 research paper Deliberate exposure of humans to chlorine — states
“There was a statistically significant increase in the clinical symptoms of healthcare workers (HCW) when they were exposed multiple times to chlorine spray. The use of chlorine to disinfect personal protective equipment (PPE) while HCW are wearing it is not only without evidence, ineffectual but can be hazardous to health. Secondly, the available PPE that was used by HCW did not protect them against the adverse effects of chlorine spray. This was because when chlorine is inhaled it converts to hydrochloric acid in the respiratory tract and causes severe clinical symptoms. Should chlorine be indicated for disinfection, it should be applied as a wipe rather than a spray. Alternatives such as 70 per cent alcohol should be considered.”
According to the wide range of experts anti-viral walk through gates is like a BAD DEBT, people should follow social distancing measures and other preventive guidelines to combat the pandemic.
