Many risks such as plant and animal biotechnology applications have the potential to generate new diseases that can be transmitted to humans. In this way, the health of humans, animals, and plants is interrelated and depends on one another. However, it has been difficult to apply the OHC in some countries, such as those in the Middle East. The absence of financial support in the region is a major hindrance to applying this concept in the region. The application of the OHC requires the support of specialists who can advocate the government for support in launching OHC-related projects. Here, we discuss the OHC in the context of antimicrobial resistance, zoonotic diseases, and biosafety/biosecurity, which are important public health issues. Furthermore, we describe the current status of the OHC in the Middle East and recent research conducted related to this concept. There has been recent international solidarity in the application of the OHC to reduce risks that threaten the health of organisms. Several countries jointly launched the Global Health Security Agenda in 2014 with the aim of realizing a world that is free of infectious disease-related health risks. However, no previous review articles have examined the applications of the OHC in the Middle East region. This article discusses the OHC in terms of its needs and current applications in the Middle East.</p></div><div><h3>Methodology</h3><p>The following keywords were used in the search: “One Health,” “Middle East,” “medicinal plants,” “viruses,” “rabies,” “MERS,” and “antimicrobial resistance.” Related papers were obtained by searching for these keywords using available search engines, such as PubMed, Google Scholar, and Google search, as well as international organization websites.</p></div><div><h3>Conclusion</h3><p>The concept of One Health is relatively new and has not been applied in most countries, possibly because the value of this concept for improving human health is not well understood. The key principle defining this concept and its importance is the interdependency of plants, animals, and human health. By applying the OHC, humans can benefit from healthy plants and animals by enhancing their growing conditions, medications, and environments. This would in turn improve general human health by allowing the safe extraction of therapeutics and food resources.</p></div>","PeriodicalId":52875,"journal":{"name":"Journal of Biosafety and Biosecurity","volume":"5 1","pages":"Pages 21-31"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44228544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although smallpox was globally eradicated in the 1980 s, it is still a top biosecurity threat owing to the possibility of either being leaked to the outside world from a laboratory or being weaponized by terrorists. Beginning in early May 2022, a sudden outbreak of monkeypox was concurrently reported in more than 100 disparate geographical areas, representing a public health emergency of international concern, as declared by the World Health Organization (WHO). In this review, we present the reasons for hpOPXVs such as monkeypox virus presenting a potential threat to public health. We then systematically review the historical and recent development of vaccines and drugs against smallpox and monkeypox.

The thermal resistance of airborne SARS-CoV-2 is lower than that of <em>Bacillus subtilis</em> spores, which are often used to test the effectiveness of SARS-CoV-2 and other pathogen disinfection methods. Herein, we propose a new method to test the disinfection ability of a flowing air disinfector (a digital electromagnetic induction air heater) using <em>B. subtilis</em> spores. The study provides an alternative air disinfection test method. The new test system combined an aerosol generator and a respiratory filter designed in-house and could effectively recover spores on the filter membrane at the air outlet after passing through the flowing air disinfector. The total number of bacterial spores used in the test was within the range of 5 × 10⁵–5 × 10⁶ colony-forming units (CFUs) specified in the technical standard for disinfection. The calculation was based on the calculation method in Air Disinfection Effect Appraisal Test in Technical Standard for Disinfection (2002 Edition). At an air speed of 3.5 m/s, we used a digital electromagnetic induction air heater to disinfect flowing air containing 4.100 × 10⁶ CFUs of <em>B. subtilis</em> spores and determined that the minimum disinfection temperature was 350 °C for a killing rate of 99.99%. At 400 °C, additional experiments using higher spore concentrations (4.700 × 10⁶ ± 1.871 × 10⁵ CFU) and a higher airspeed (4 m/s) showed that the killing rate remained&gt;99.99%. <em>B. subtilis</em> spores, as a biological indicator for testing the efficiency of dry-heat sterilization, were killed by the high temperatures used in this system. The proposed method used to test the flowing air disinfector is simple, stable, and effective.

The current article analyzes this event-driven regulatory reform in China by elaborating the most salient provisions designed to prevent risk and protect individual rights, public health, and social morality relating to human genome editing in four important sectors of law: biosecurity law, civil code, criminal law and patent law. It highlights that, although regulation is being undertaken, the gaps between the law and advancing technology remain discernible, at both a national and transnational level (i.e., the “double-pacing problem”).

In this current study, 665 SARS-CoV-2 genomes from China deposited in the public database were used to analyze the proportion of different variants; to determine the composition of variants in China across different provinces; and analyze specific mutation frequency, focusing on 12 immune escape residues. The results showed that no new mutations were generated on the 12 immune escape residues. The evolutionary analysis of the BF.7 variant circulating in China showed that there is an independent evolutionary branch with unique mutation sites, officially named BF.7.14 by PANGO. This variant may have been imported from Russia to Inner Mongolia at the end of September 2022 and continued its spread in China. The evolutionary analysis of BA.5.2 variant shows that the variant is composed of two sub-variants, named BA.5.2.48 and BA.5.2.49 by PANGO, respectively. This variant may have been imported from abroad to Beijing at the beginning of September 2022 and formed two sub-variants after domestic transmission.

Today, the number of SARS-CoV-2 genomes exceeds the total number of all other viral genomes. These genomes are a record of the evolution of SARS-CoV-2 in the human host, and provide information on the emergence of mutations. In this study, analysis of these sequenced genomes identified 296,728 <em>de novo</em> mutations (DNMs), and found that six types of base substitutions reached saturation in the sequenced genome population. Based on this analysis, a “mutation blacklist” of SARS-CoV-2 was compiled. The loci on the “mutation blacklist” are highly conserved, and these mutations likely have detrimental effects on virus survival, replication, and transmission. This information is valuable for SARS-CoV-2 research on gene function, vaccine design, and drug development. Through association analysis of DNMs and viral transmission rates, we identified 185 DNMs that positively correlated with the SARS-CoV-2 transmission rate, and these DNMs where classified as the “mutation whitelist” of SARS-CoV-2. The mutations on the “mutation whitelist” are beneficial for SARS-CoV-2 transmission and could therefore be used to evaluate the transmissibility of new variants.
