SURFACES AND MATERIALS ANTIVIRAL ACTIVITY
We are pleased to announce the publication of the study "Antiviral Activity of Active Materials: Standard and Finger-Pad-Based Innovative Experimental Approaches" in the international review Materials.
This study was carried out in partnership with the International Centre for Infectiology Research (CIRI Centre International de Recherche en Infectiologie, Virpath team). It presents comparative data from different experimental procedures and allows
defining antiviral activities of several active materials and coatings against pathogenic enveloped and non-enveloped viruses. This publication also presents an innovative experimental approach to evaluate the antiviral activities of active materials
against finger-pad viral contamination. This approach is part of VirHealth's overall strategy to develop and deliver innovative laboratory trial solutions that simulate the contamination of materials and coatings in real-life conditions.
Surface disinfection - New Test Bench
VirHealth has developed a new test bench to meet the requirements of EN17272 (2020, airborne disinfection system) for small-enclosure efficacy tests of 2 m3.
Also, this tool allows us to carry assays to evaluate virucidal and microbicidal activities on surfaces of passively diffused products (alcohol, essential oils, etc.).
Partnership with NeoVirTech!
We are pleased to announce our partnership with NeoVirTech!
NeoVirTech and VirHealth join their virology expertise to provide customers one of the most extended virus disinfection measurement and R&D platform in France and in Europe. This alliance will allow the partners to combine their
respective expertise in an integrated offer dedicated to increase knowledge in virus persistence in the environment, virus disinfection procedure and to provide customer state of the art models for the measurement of disinfection
procedures using innovative and standardized approaches.
SURFACES AND MATERIALS ANTIVIRAL ACTIVITY
Surfaces with antiviral activities participate in the management of viral contamination by reducing
the infectious virus load over time. We offer standardized or adapted protocols to evaluate the
antiviral efficacy of porous and non-porous surfaces on a large panel of viruses (enveloped and non-
enveloped) including alpha/beta coronaviruses.
SARS-COV-2 STABILITY ON SURFACE AND DISINFECTANT
Our last preprint on the role of interfering substances on SARS-CoV-2 surface stability and virucidal efficiency of hand sanitizers and disinfectants is now available in MedRxiv.

Contaminated environmental surfaces are considered to represent a significant vector for hospital-acquired viral infections and indirect contact transmission involving these surfaces could be the predominant transmission route for respiratory viruses. In collaboration with #VirPath, #VirHealth has used both EN14476 and EN16777 standardized protocols for evaluation of virucidal activity using tailor-made interfering substances corresponding to artificial mixture containing nasal mucus and saliva. They reflect current “real life” conditions of use by considering the impact of omnipresent secretions from coughing or sneezing. In this study, we have measured surface stability of SARS-CoV-2 and other coronavirus in different experimental conditions and demonstrated that interfering substances (nasal mucus, saliva) play an important role in the virucidal efficiency of disinfectants.
SARS-COV-2 (COVID-19)
Since 2015, VirHealth has been working in partnership with Virpath laboratory (Dr Rosa-Calatrava,
CIRI, Lyon) as part of a research and innovation program in order to answer the institutions and
manufacturers needs during health crises and viral epidemics/pandemics (Avian Influenza, MERS-
CoV coronavirus,…).
Since March 2020, we have been jointly carrying out virucidal activity tests of disinfection products and equipment on Sars-Cov-2 (COVID-19). We also lead applied research programs to better understand
the virus biology and offer technical approaches for setting up appropiate testing strategies.
