In December 2019, a pneumonia outbreak was reported in the Wuhan City of China. The outbreak was traced to a novel strain of coronavirus on 31 December 2019, which was given the interim name 2019-nCoV by the World Health Organization (WHO), later renamed SARS-CoV-2 by the International Committee on Taxonomy of Viruses. The Wuhan strain has been identified as a new strain of beta coronavirus from group 2B having approximately 70% genetic similarity to the SARS-CoV. The virus has a 96% similarity to a bat coronavirus and hence is widely suspected to be originated from bats as well. CoVs are a large family of viruses from the Coronaviridae family, including Middle East Respiratory Syndrome (MERS)-CoV, Severe Acute Respiratory Syndrome (SARS)-CoV and the new virus named SARS-CoV-2 [1–2]. Since it was first reported, the disease has spread exponentially across the world. However, currently there is no approved human vaccine that can prevent the disease with 100% accuracy. It has been observed that the spread of COVID-19 has been fastest when people are in close proximity. Travel restrictions were thus imposed in countries to control the spread of the virus, and frequent hand washing/sanitising is recommended to prevent potential virus infections. The most common infection symptoms are cough and mild fever and may appear in COVID-positive patients. However, other symptoms including chest discomfort, sputum development and sore throat may also occur.

Currently, health care workers are giving their full efforts and support to control this epidemic. In February, 2020, the World Health Organization (WHO) published the authorized name for the current coronavirus as COVID-19, which is produced by SARS-CoV-2 (Hageman, 2020; Sun et al., 2020; Kuldeep et al., 2020). Originally, a group of coronavirus patients was identified in the Huanan South China Seafood marketplace in Wuhan (Gralinski and Vineet, 2020). Coronavirus is in the Coronaviridae group and the Coronavirinae subgroup. The novel coronavirus is genetically distinct. Up to 2020, there were six Covs known to infect humans (Fan et al., 2019). COVID-2019 disease emerged in China and spread rapidly to other countries. The severity of the disease and its rapid spread spurred WHO to announce a global health emergency day on 31st January, 2020. Afterwards, a pandemic situation was declared on 11th March, 2020. At present, there is no effective treatment for COVID-19, since there is no approved vaccination or drugs for giving humans with coronavirus infections. Currently all nations are working hard to prevent the further spread of COVID-19 (Kuldeep et al., 2020).

With the pandemic outbreak in China in late 2019, sequencing technologies could help identify the causative organism of the pandemic, i.e., SARS-CoV-2, a type of betacoronavirus. The Coronaviridae Study Group (CSG) of the International Committee on Taxonomy of Viruses placed the pathogen within the Coronaviridae and tentatively named it 2019-nCoV. Phylogenetic analysis revealed that the virus formed a sister clade with human and bat SARS-CoVs of the severe acute respiratory syndrome-related coronaviruses. Therefore, it was referred to as SARS-CoV-2 (Coronaviridae Study Group of the International Committee on Taxonomy of Viruses 2020).
Disinfecting Efficacy of an Ozonated Water Spray Chamber: Scientific Evidence of the Total and Partial Biocidal Effect on Personal Protective Equipment and in Vitro Analysis of a Viral Experimental Model

Regarding the results obtained in the viral inactivation analysis using Gammacoronavirus, strain Massachusetts (enveloped virus causing chicken infectious bronchitis), a virus belonging to the Coronaviridae family served as an experimental model aimed at a possible application of ozonated water to SARS-CoV-2. Among the most abundant viruses that infect a wide variety of animals, including birds and humans, we find the viruses of the Coronaviridae Family (Miłek and Blicharz-Domańska 2018; Sizun, Yu, and Talbot 2000). Members of this family include human pathogens, such as severe acute respiratory syndrome virus (SARS-CoV-2) (Coronaviridae Study Group of the International Committee on Taxonomy of Viruses 2020), and animal pathogens, such as porcine epidemic diarrhea virus (Chen et al. 2019), avian coronavirus (ACoV) (Promkuntod 2016), and beluga whale coronavirus SW1 (SW1) (Mihindukulasuriya et al. 2008). Since we are experiencing a third documented contagion from an animal coronavirus to humans in just two decades, resulting in a major epidemic, research focused on pathogenic viruses will improve our understanding of applications of alternative therapies to combat these viruses in the environment.
