The WHO has declared COVID-19 illness a global health concern which is caused by 2019-nCoV, causing severe respiratory tract infections in humans. Transmissibility among individual to individual have been reported through droplets and probably also via contaminated surfaces and hands. Human coronaviruses can persist on inanimate surfaces such as plastic, glass, fibers and metals up to nine days. 2019-nCoV remains infectious in air for 3 h and on inanimate surfaces such as cardboard, copper, plastic and steel up to 24, 4, 72 and 48 h respectively. Disinfectant activity of various biocidal agents against coronaviruses like ethanol (62-71%), sodium hypochlorite (0.1%) and hydrogen peroxide (0.5%) can be regarded effective against 2019-nCoV as well. As no vaccine and antiviral therapies have been discovered for 2019-nCoV, prevention of further spread will viable option to control the ongoing and future outbreaks.
世界卫生组织已宣布新型冠状病毒肺炎为全球关注的公共卫生事件，该病由2019新型冠状病毒引起，可导致人类严重呼吸道感染。据报道，人与人之间可通过飞沫传播，也可能通过污染的表面和手部传播。人类冠状病毒可在塑料、玻璃、纤维和金属等无生命表面存活长达九天。2019新型冠状病毒在空气中可存活3小时，在纸板、铜、塑料和钢铁等无生命表面分别可存活24小时、4小时、72小时和48小时。各种消毒剂如乙醇（62-71%）、次氯酸钠（0.1%）和过氧化氢（0.5%）对冠状病毒的消毒活性也可被视为对2019新型冠状病毒有效。由于尚未发现针对2019新型冠状病毒的疫苗和抗病毒疗法，预防进一步传播将是控制当前及未来疫情爆发的可行选择。
