Abstract

Objective: To characterize the impact of SARS-CoV-2 infection in workers from an essential large-scale company in the Greater Mexico City Metropolitan Area using point prevalence of acute infection, point prevalence of past infection through serum antibodies and respiratory disease short-term disability claims (RD-STDC).

Materials and methods: Four randomized surveys, three during 2020 before and one after (December 2021) vaccines' availability.

Outcomes: point prevalence of acute infection through saliva PCR (polymerase chain reaction) testing, point prevalence of past infection through serum antibodies against Covid-19, RD-STDC and prevalence of symptoms during the previous six months.

Results: Prevalence of SARS-CoV-2 cases was 1.29-4.88%, on average, a quarter of participants pre-vaccination were seropositive; over half of participants with a RD-STDC had antibodies. The odds of having antibodies were 6-7 times more among workers with an RD-STDC.

Conclusions: High antibody levels against Covid-19 in this study population reflects that coverage is high among workers in this industry. STDCs are a useful tool to track workplace epidemics.

墨西哥城大都会区的 SARS-CoV-2 血清流行率和呼吸道疾病伤残索赔。

目的利用急性感染点流行率、通过血清抗体检测的既往感染点流行率和呼吸系统疾病短期伤残索赔（RD-STDC），确定大墨西哥城都会区一家重要大型公司的工人感染 SARS-CoV-2 的影响：结果：通过唾液 PCR（聚合酶链式反应）检测获得急性感染点流行率，通过血清 Covid-19 抗体获得既往感染点流行率，RD-STDC 和前六个月的症状流行率：SARS-CoV-2病例的流行率为1.29%-4.88%，平均四分之一接种前的参与者血清呈阳性；超过一半的 RD-STDC 参与者有抗体。接种过 RD-STDC 的工人出现抗体的几率是其他人的 6-7 倍：结论：本研究人群中 Covid-19 抗体水平较高，反映出该行业工人的感染率较高。STDC 是追踪工作场所流行病的有用工具。
