This review presents a synopsis on the current COVID-19 pandemic, with focus on preventive measures. COVID-19 is a new viral infection, and is in form of a positive-sense, single-stranded RNA Coronavirus which belongs to an expanded group of viruses which were identified six decades ago. Importantly, the new COVID-19 belongs to the group of SARS-CoV, and it originated in bats but infected humans through smuggled pangolins. At first, the mode of transmission of infection was animal-to-person, but person-to-person and community transmission of the virus has been confirmed in many parts of the world. With an incubation period of between two-fourteen days, signs and symptoms of infection are mild to high respiratory illness; characterized with cough, breathing problems (shortness of breath), high temperature (Fever), tiredness (Fatigue) and nausea. Presently, no vaccines or specific treatment is available for COVID-19, in light of the aforementioned; prevention is the only substantial and less expensive option. With the envisaged explosive community transmission of COVID-19 in the coming weeks in places with limited daily testing, especially in African countries, it is recommended among many that social distancing which includes avoiding any form of contact with people; either through greetings, hugging or shaking of hands and large gatherings, avoid contact with animal items, dead or alive animals, sick and dead people from areas experiencing COVID-19 epidemic, and basic hygienic practices like thorough washing of hands with clean water and antiseptic soap for the duration of at least twenty seconds should be practiced always. However, in the absence of the aforementioned, an alcohol-based hand gel should be used on the hands frequently. Furthermore, health care workers should adhere strictly to the standard preventive measures in areas of heightened COVID-19 epidemic.
本综述概述了当前的新冠疫情,重点关注预防措施。新冠病毒是一种新的病毒感染,呈正链单链RNA冠状病毒形式,属于六十年前发现的一组扩展病毒。重要的是,新型新冠病毒属于严重急性呼吸综合征冠状病毒(SARS-CoV)类别,它起源于蝙蝠,但通过走私穿山甲感染人类。起初,感染传播方式是动物传人,但病毒的人际传播和社区传播已在世界许多地区得到证实。潜伏期为2至14天,感染的体征和症状为轻度至重度呼吸道疾病;特征为咳嗽、呼吸问题(呼吸急促)、高烧(发热)、疲劳和恶心。目前,尚无针对新冠病毒的疫苗或特效治疗方法,鉴于上述情况,预防是唯一切实可行且成本较低的选择。鉴于预计未来几周在每日检测有限的地区,尤其是非洲国家,新冠病毒将出现爆发性社区传播,许多人建议保持社交距离,包括避免与他人进行任何形式的接触,如问候、拥抱或握手以及避免大型聚会,避免接触动物制品、死的或活的动物、来自新冠疫情地区的病人和死者,并且应始终坚持基本卫生习惯,如用清水和抗菌肥皂彻底洗手至少20秒。然而,在无法做到上述要求时,应经常使用含酒精的洗手液洗手。此外,医护人员在新冠疫情高发地区应严格遵守标准预防措施。
