Dear All,
This publication (in press yesterday) notes the following in the summary:
*”The analysis of 22 studies reveals that human coronaviruses such as
Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East
Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses
(HCoV) can persist on inanimate surfaces like metal, glass or plastic for up
to 9 days, but can be efficiently inactivated by surface disinfection
procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium
hypochlorite within 1 minute”.Kampf G, et al. Persistence of coronaviruses on inanimate surfaces and its
inactivation with biocidal agents, Journal of Hospital Infection, https://

Hi Glenys and all,
(I declare my conflict of interest as a medical device disinfectant supplier), however, my point is NON COMMERCIAL IN NATURE.
Re the current Corona Virus situation: I have noticed something concerning during my interactions with Public Hospital Ophthalmic and Optometry/Orthoptic departments and Private Practices/Optometry sites- and that is overwhelming the use of Isopropyl Alcohol Wipes as a supposed “disinfectant” for Medical devices contacting the eye or secretions of the eye.
The concern is two fold and point 2 relates to Corona Virus.
1. Isopropyl Alcohol requires a wet contact time of 5 minutes to be Bactericidal, but the alcohol has a flash point/drying time of approx. 40 Seconds so the bactericidal effect not completed
2. Isopropyl Alcohol Wipes are NOT VIRUCIDAL, with any length of contact time.I have had many discussions with Hospitals regarding the selection of a disinfectant that is effective against ADENOVIRUS (as this is a leading cause of Kerato-Conjunctivitis) and as such requires a disinfectant that is at least Viricidal.
Now though, the reports and evidence are suggesting/confirming that Corona Virus is transmissible via the mucosa of the eye as well as via the secretions, just as SARS was identified as transmissible in this way during that outbreak event. The recommendations are for full PPE including Eye protection for carers in the outbreak zone. And whilst this is prudent for protection of healthcare workers, it does not address the reprocessing of the Ophthalmic Medical Devices which contact the eye during Ophthalmic/Orthoptic diagnostic and therapeutic procedures.
I believe this is currently an entirely overlooked pathway of Virus transmission, and it concerns me greatly that two peak organisations here in Australia- Optometry Australia and RANZCO (college of Ophthalmology) actively promote the use of Isopropyl Alcohol for disinfection, (and 5,000ppm of Sodium Hyper-Chlorite) in direct conflict with the requirements of ASNZ 4187.
Just by way of reminder, the requirement under the ASNZ 4187 (as a MINIMUM) is for HIGH LEVEL DISINFECTION of Medical Devices used in contact with broken skin and Mucosal surfaces.
The product selected MUST be: a TGA approved, INSTRUMENT GRADE, HIGH LEVEL DISINFECTANT (Class 2B)- not a listed or registered disinfectant, also known as an OTG (other therapeutic good)- products with this level of registration are ONLY approved for use as SURFACE disinfectants, not device disinfectants.
I am interested in the opinion of others on this forum as to 1. the risk and 2. the desire to close that GAP by insisting only High Leve, Instrument Grade disinfectants be used in this space (with the required appropriate tracking/auditing capability), as required by ASNZ 4187.
Yours Sincerely

Dear Scott,
When advising eye specialists in their office based practice, I ask them to
firstly review what items are labelled single use (first surprise) and for
any reusable items to then check the manufacturers’ instructions for
reprocessing – that deals with most of my issues but comes as a shock to
them. I have checked the cost of disposables where available and this is
minimal and of course no excuse to achieving the required standard. You
mention other equipment – not only is the required wet contact time ever
adequate (not to mention no cleaning), there are contraindications to using
alcohol on various items because of the damage it may cause to contact
cement etc.I’d like to know what standard your clients are following that permits an
alcohol wipe of a single use item or insufficient device decontamination of
a reusable piece of equipment? As you point out, where they are making
contact with the surface of the eye, such contact is not the same as contact
with intact skin and any reprocessing is to be done to a standard. Corona
virus and adeno virus aside, we know that many other respiratory viruses e.g
influenza can access via the eyes/tear ducts.I am sure that Terry MacAuley will have more to say on this as it’s a topic
we have corresponded on regarding the disposables.Regards,
Margaret Jennings

Dear Scott
Thank you for sharing your very considered thoughts.
I understand the issue that healthcare facilities encounter is that the recommended cleaning products listed by the manufacturers are either not available in Australia and/or not registered via TGA.
This leaves healthcare services to undertake a review of currently available like cleaning agents via their product review processes and then decide which they will use.
It would be helpful if equipment suppliers were to provide a range of cleaning agent/product options that are available in Australia to encourage compliance in this area. Keeping in mind that the more products available can also cause confusion (and add to costs) in the workplace and also lead to non compliance.
Maybe an equipment industry alliance similar to the hand hygiene industry alliance might help address this challenging situation.

Hi Marg,
New publication posted on 13th March 2020.
Aerosol and surface stability of HCoV-19 (SARS-CoV-6 2) compared to
SARS-CoV-1medRxiv preprint doi: https://doi.org/10.1101/2020.03.09.20033217
*”HCoV-19 (SARS-2) has caused >88,000 reported illnesses with a
current case-fatality ratio of ~2%. Here, we investigate the stability of
viable HCoV-19 on surfaces and in aerosols in comparison with SARS35 CoV-1.
Overall, stability is very similar between HCoV-19 and SARS-CoV-1. We found
that viable virus could be detected in aerosols up to 3 hours post
aerosolization, up to 4 hours on copper, up to 24 hours on cardboard and up
to 2-3 days on plastic and stainless steel. HCoV-19 and SARS-CoV-1 exhibited
similar half-lives in aerosols, with median estimates around 2.7 hours. Both
viruses show relatively long viability on stainless steel and polypropylene
compared to copper or cardboard: the median half-life estimate for HCoV-19
is around 13 hours on steel and around 16 hours on polypropylene. Our
results indicate that aerosol and fomite transmission of HCoV-19 is
plausible, as the virus can remain viable in aerosols for multiple hours and
on surfaces up to days.Regards

Aerosol and surface stability of HCoV-19 (SARS-CoV-6 2) compared to SARS-CoV-1
medRxiv preprint doi: https://doi.org/10.1101/2020.03.09.20033217* “HCoV-19 (SARS-2) has caused >88,000 reported illnesses with a current case-fatality ratio of ~2%. Here, we investigate the stability of viable HCoV-19 on surfaces and in aerosols in comparison with SARS35 CoV-1. Overall, stability is very similar between HCoV-19 and SARS-CoV-1. We found that viable virus could be detected in aerosols up to 3 hours post aerosolization, up to 4 hours on copper, up to 24 hours on cardboard and up to 2-3 days on plastic and stainless steel. HCoV-19 and SARS-CoV-1 exhibited similar half-lives in aerosols, with median estimates around 2.7 hours. Both viruses show relatively long viability on stainless steel and polypropylene compared to copper or cardboard: the median half-life estimate for HCoV-19 is around 13 hours on steel and around 16 hours on polypropylene. Our results indicate that aerosol and fomite transmission of HCoV-19 is plausible, as the virus can remain viable in aerosols for multiple hours and on surfaces up to days.

This publication (in press yesterday) notes the following in the summary:
* The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute.

Hi Belinda,
The paper I posted was in relation to aerosol and surface contamination of HCoV-19 (SARS-2)- as per below:
Aerosol and surface stability of HCoV-19 (SARS-CoV-6 2) compared to SARS-CoV-1
medRxiv preprint doi: https://doi.org/10.1101/2020.03.09.20033217
*”HCoV-19 (SARS-2) has caused >88,000 reported illnesses with a current case-fatality ratio of ~2%. Here, we investigate the stability of viable HCoV-19 on surfaces and in aerosols in comparison with SARS35 CoV-1. Overall, stability is very similar between HCoV-19 and SARS-CoV-1. We found that viable virus could be detected in aerosols up to 3 hours post aerosolization, up to 4 hours on copper, up to 24 hours on cardboard and up to 2-3 days on plastic and stainless steel. HCoV-19 and SARS-CoV-1 exhibited similar half-lives in aerosols, with median estimates around 2.7 hours. Both viruses show relatively long viability on stainless steel and polypropylene compared to copper or cardboard: the median half-life estimate for HCoV-19 is around 13 hours on steel and around 16 hours on polypropylene. Our results indicate that aerosol and fomite transmission of HCoV-19 is plausible, as the virus can remain viable in aerosols for multiple hours and on surfaces up to days.
I have a conflict of interest in terms of the use of hydrogen peroxide as I consult to a company that markets such a product for cleaning and disinfecting to the healthcare industry in Australia, hence Im not able to comment in this private members forum on a specific products.
Happy to be contacted directly to discuss further if needed contact details below.

Dear Glenys
Thanks for the information. Is there a dilution ratio for the use hydrogen peroxide when cleaning surfaces?
Warm regards

Dear All,
This publication (in press yesterday) notes the following in the summary:
*The analysis of 22 studies reveals that human coronaviruses such as Severe Acute Respiratory Syndrome (SARS) coronavirus, Middle East Respiratory Syndrome (MERS) coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute.
Kampf G, et al. Persistence of coronaviruses on inanimate surfaces and its inactivation with biocidal agents, Journal of Hospital Infection, https:// doi.org/10.1016/j.jhin.2020.01.022 .
May be of interest/use.
