摘要:

病媒生物可通过机械性传播病毒,有的类群还可生物性传播病毒,病媒生物是否可以传播新型冠状病毒(新冠病毒),该文针对几种与人类关系密切的病媒生物,做了传播新冠病毒风险的评估研究,以便为更精准的新型冠状病毒肺炎防控决策提供依据。通过收集文献,利用风险矩阵法对病媒生物传播新冠病毒可能性进行评分,确定不同病媒生物及其在不同场所的新冠病毒暴露和传播风险等级。初步结果为:蚊虫机械性和生物性传播新冠病毒的风险极低;鼠、蜚蠊、蝇3类病媒生物具有机械性传播新冠病毒的潜在风险,鼠类还存在生物性传播新冠病毒的潜在风险;不同场所病媒生物传播新冠病毒的风险不同,传播风险等级与新冠病毒暴露风险等级和病媒生物的分布范围、密度及活动能力等相关。总体上,可排除蚊虫传播新冠病毒的风险;鼠、蜚蠊、蝇等病媒生物,在新冠病毒暴露的特殊场所和局部环境,具有潜在传播新冠病毒的风险,但风险较低。

Abstract:

Vectors can transmit viruses by mechanical transmission, and some species can transmit viruses by biological means. As for whether vectors can transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), this article assess the risk of several categories of vectors closely related to humans in transmitting SARS-CoV-2, so as to provide a basis for developing more precise SARS-CoV-2 prevention and control measures. Based on the collected literature, the risk matrix method was used to evaluate the probability of vectors transmitting SARS-CoV-2 and determine the level of exposure to SARS-CoV-2 and the risk level of SARS-CoV-2 transmission for different vectors in different places. The preliminary results showed that the risk of mosquitoes in transmitting SARS-CoV-2 was very low; rodents, cockroaches, and flies had a potential risk of mechanical transmission of SARS-CoV-2, and rodents also had a potential risk of biological transmission of SARS-CoV-2; the three categories of vectors had different risks of the transmission of SARS-CoV-2 in different places, and the risk level of transmission was associated with the risk level of exposure to SARS-CoV-2, as well as the distribution, density, and activity of vectors. In general, the risk of mosquitoes in transmitting SARS-CoV-2 could be excluded; the vectors including rodents, cockroaches, and flies have a potential but low risk of transmitting SARS-CoV-2 in specific places and surroundings exposed to SARS-CoV-2.
