Hygienic hand disinfection is one of the most important measures to prevent viral infections in hospitals and other medical facilities. Guidelines strictly emphasize the urgent need of hand hygiene procedures with alcohol-based hand rubs. Its application requires products with a proven efficacy against model viruses evaluated in a quantitative suspension test and/or on artificial contaminated finger pads (ASTM 1838-10) or the entire hand (ASTM 2011-09). Unfortunately, both ASTM methods do not follow the clinical practice in hospitals and other medical facilities.So far there is no method available in Europe to determine the antiviral efficacy on contaminated hands. Nowadays, efforts by the CEN committee (virus task group) are undertaken to develop a method which resembles both contamination and hand treatment in clinical practice as closely as possible. In the WI (work item) 00216088 the recent developments are described.The murine norovirus (MNV) is chosen as test virus. The finger pads (including the thumb) are inoculated in 0.5 ml of the contamination fluid (murine norovirus suspension) in 12 or 24 well plates for 15 s. Then surplus liquid is carefully allowed to drain back into the container for a maximum of 30 s. Fingers are dried under the safety cabinet for 3 min.For hand hygiene 3 ml of the hand disinfectant are poured into the cupped dry hands and rubbed vigorously for 30 seconds onto the skin up to the wrists in accordance with the standard hand rub (EN 1500) procedure to ensure total coverage of the hands.Immediately at the end sampling from each fingertip (including the thumb) is started with 1 ml sample fluid per finger. Therefore, each fingertip is rubbed for 1 min on the base of a small Petri dish with 1 ml cell culture medium. Finally, the titer of residual virus is determined.The virus lab of Dr. Brill + Partner in Bremen is involved in the still running ring trials in Europe since the beginning together with 2 other labs in Europe and one lab in the United States. Recently, studies were performed in these 4 labs to find out the reference testing different concentrations of ethanol.Studies are still on-going for developing the European test method for evaluating the virus inactivation on artificially contaminated hand. Dr. Brill + Partner GmbH will continuously participate in these studies. A previous study done in our lab in Bremen independently from these European efforts has been published in 2012 demonstrating the large competence in this field.J. Steinmann, D. Paulmann, B. Becker, B. Bischoff, E. Steinmann, J. Steinmann: Comparison of virucidal activity of alcohol-based hand sanitizers versus antimicrobial hand soaps in vitro and in vivo.  J Hosp Infect (82): 277-280 (2012)If you have further questions, please do not hesitate to contact us.

In September 2014, the first phase 2/step 2 European standard prEN 16777 for virucidal efficacy testing of surface disinfectants on non-porous stainless steel discs was published. With adenovirus type 5 and murine norovirus (MNV) strain S99 as test viruses, the use-recommendations of surface disinfectants will strongly improve because there is a practice-like test method for virucidal efficacy evaluation available.To this day, the EN 14476 (phase 2, step 1) as quantitative suspension test with polio-, adeno- and norovirus serves as the basis for efficacy evaluation of surface disinfectants. The successful inactivation test according to EN 14476 allowed a virucidal claim of the product. But the extent of virus inactivation by chemical means often completely differs when testing in vitro (quantitative suspension test) and in vivo (carrier test). After introduction of the prEN 16777 a test simulating practical conditions is now available which will allow more realistic use-recommendations (virucidal claim) and which will be the basis together with EN 14476 for biocidal product registration in Europe.In this prEN, a test virus suspension together with a soil load (virus inoculum) is dried on a stainless steel disc before the disinfectant is added. After the chosen exposure time has been reached a recovery process is followed to determine residual viral infectivity on the carriers. Our lab is highly experienced in carrier tests and was significantly involved in the development of the method. In 2008, we already started to study the efficacy of various active ingredients of disinfectants against the murine norovirus as new surrogate of human norovirus in the carrier test (Magulski et al. 2009). Furthermore, we participated in the ring trials of DVV with the same topic (Rabenau et al. 2014) and in all European carrier ring trials with MNV and adenovirus type 5. In addition, the lab took part in the OECD ring trial with adenovirus testing PAA based formulations in 2008.
