Background
Coronaviruses are a large family of viruses. Some can cause illness in people including mild
symptoms, such as the common cold. Other strains can lead to pneumonia and cause more
severe disease e.g. SARS and MERS.
Surface disinfection
Selgiene Ultra and Selgiene Extreme have been assessed for virucidal activity following test
methods such as BS EN 14476 and BS EN 14675. Results show they are effective against a
range of viruses such as the H1N1 influenza virus, Norovirus, Hepatitis B, Hepatitis C, HIV and
the Ebola virus.
The Coronavirus is not currently available for commercial laboratories to test against so we
cannot give a definitive contact time and dilution rate. However, given the above test data
we can reasonably expect Selgiene Ultra and Selgiene Extreme to have efficacy against the
virus.
We would therefore recommend using the below products for general disinfection in the
infection prevention and control for the 2019-nCoV.
Product | Concentration | Contact time |
C066/C500 | 1:10 | 5 minutes |
T066/T500 | Neat | 5 minutes |
Where specific cases are suspected or identified we would recommend an additional step of
applying 1000ppm bleach (after precleaning with T500/T066). We advise the use of
T066/T500 for precleaning to minimise the risk that the cleaning cloths become a source of
cross contamination.
To achieve 1000ppm bleach see below products.
Product Preparation Concentration Contact time
YC17 1 tablet in 1L water 1000ppm 15 minutes
T025 Ready to use 10,000ppm 5 minutes
Hand hygiene
Wash hands with soap and water for at least 20 seconds or use an alcohol hand rub such as
C053 if hands are visibly clean.
