In a Nicaraguan population-based cohort, SARS-CoV-2 seroprevalence reached 28% in the first 6 months of the country's epidemic and reached 35% 6 months later. Immune waning was uncommon. Individuals with a seropositive household member were over three times as likely to be seropositive themselves, suggesting the importance of household transmission.
在尼加拉瓜基于人群的队列研究中,该国疫情的前 6 个月,SARS-CoV-2 血清阳性率达到 28%,6 个月后达到 35%。免疫衰减并不常见。家中有血清学阳性成员的个体自身呈血清学阳性的可能性是其三倍以上,这表明家庭传播的重要性。
