The corona has four family members Alphacoronavirus, Betacoronavirus, Gamma-coronavirus, and Deltacoronavirus. These techniques are applicable to three types of infections excluding Gammacoronavirus. Alphacoronavirus and Betacoronavirus infect only mammals such as humans, pigs, bats, and cats. Gammacoronavirus affects only birds, while Deltacoronavirus infects both mammals and birds. Different family of the virus shows different symptoms in animals such as in chicken, as it causes upper respiratory tract disease in them, but in cows, pigs, and turkeys, it causes bad cold and diarrhea. This is causing with mortality rate approximately 3%—15%. The source of this virus is not yet identified (bats, snakes, etc.).

Coronaviruses (CoV) are among the aetiological agents of human diseases (Chen et al., 2020). The critically important group called the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) belongs to genus Betacoronavirus, subgenus Sarbecovirus (Boheemen et al., 2012). SARS-CoV-2 is responsible for COronaVIrus Disease 2019 (COVID-19). Epidemics of Severe Acute Respiratory Syndrome CoV (SARS-CoV) in China in 2002–2003 led to about 10% mortality from 8,000 cases. In addition, there was the endemic Middle East Respiratory Syndrome CoV (MERS-CoV) in the Arabian Peninsula for around 8 years (Cheng et al., 2007; Chan et al., 2013). Severe Acute Respiratory Syndrome CoV-2 (SARS-CoV-2) is a single-stranded (positive-sense) RNA virus. The RNA genome is linked to a nucleoprotein inside a capsid containing matrix protein. Structurally, they are either spherical or pleomorphic with glycoprotein projection in its envelope. (Haan et al., 1998) remarked that some Coronaviruses bear Hemagglutinin-Esterase (HE) protein.

Pandemics are known to have a severe negative impact on SC activities across industries. Several studies have attempted to offer a clear picture of previous pandemics and the novel coronavirus. For example, Liu et al. (2020) pointed out that before the emergence of COVID-19, six human coronaviruses had been identified, making the novel coronavirus (COVID-19) the seventh confirmed from this genome. As pointed out by a few references (Banerjee et al. 2019; Madhugiri et al. 2018; Yang and Leibowitz 2015), the genome of the virus is classified into four genera within the subfamily of Orthocoronavirinae: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus. SARS (COVID-19 inclusive) and MERS belong to the Betacoronavirus genus. Similarly, Hu et al. (2017) found that the agent of COVID-19 (i.e., the SARS coronavirus or SARS-CoV) is a member of Lineage B of the Betacoronavirus genus in the Coronaviridae family.
Evaluation of surface disinfection methods to inactivate the beta coronavirus Murine Hepatitis Virus

Our study evaluated four COTS disinfectants for efficacy against Murine Hepatitis virus, strain A59 (MHV), a betacoronavirus and presumed surrogate for SARS-CoV-2, on four surfaces. The disinfectants included three commercially available EPA List N products and the diluted bleach recipe recommended by the Centers for Disease Control and Prevention (CDC) (CDC 2020, 2021a) for efficacy against coronaviruses on non-porous and porous surfaces. The intent was to evaluate disinfection with and without physical cleaning (wiping) on surfaces common to the public sector [SS, SBR rubber (SBR), latex painted drywall tape (paint), and bus seat fabric (SF)]. Additionally, trigger-pull and ESS application methods were compared.
