Human skin is not known to carry viruses as part of its resident microbiota, with the exception of papillomaviruses. However, hands temporarily contaminated with viruses serve as vehicles for the spread of many types of viral infections. Hand hygiene is essential to reduce the burden of viruses and other transient microorganisms on the hands, thereby reducing the risk of disease transmission. is important. Such reductions in viral load occur in two ways:
The ASTM E1838-17 standard, published by the American Society for Testing and Materials (ASTM), defines a test method for determining the comparative virus elimination efficacy of microbicidal or non-microbicidal formulations. However, this test method is not intended for use with surgical hand rubs or preoperative skin preparations.
Meanwhile, this test method must be administered by persons trained in virology in facilities designed and equipped to work with infectious agents at biosafety level 2.
Briefly, this in vivo test method was designed to test the ability of hygienic hand wash and hand rubs to reduce levels of infectious viruses selected from experimentally contaminated fingertips of adults. Two thumb pads and all eight finger pads are contaminated with virus and wet inoculum entry control, dried virus recovery control and virus eradication effectiveness are evaluated.
This test method should be performed by a trained person responsible for selecting the appropriate host system for the test virus and applying the techniques necessary for the host and the propagation and maintenance of the test virus.
The method described here relates to testing with viruses of human origin, but can be easily adapted to work with bacteriophages and animal pathogenic viruses.
Our organization, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, within the scope of ASTM E1838-17 standard. It also provides standard testing services to determine the virus-removing effectiveness of hygienic hand washing and hand rubs using the fingertips of adults.
