The survival time of omikron virus in vitro is related to the specific environment and needs to be analyzed in detail, so it is not appropriate to make a generalization. Omicron can survive on smooth objects for about 7 days and is still contagious; Omicron survives on uneven surfaces such as tissue paper and printer paper for only about 30 minutes. In addition, omicron survived on plastic surfaces for up to 8 days. Omicron tends to be more stable than the original strain on different materials and surfaces. In addition, the survival time of Omicron outside the body is influenced by other factors, such as the outside temperature as well as humidity, which can directly affect the survival of Omicron. Omicron has a certain degree of danger, it is recommended that you need to actively do a good job of prevention.
