BACKGROUND: Covid-19 has been one of the major concerns around the world in the last 2 years. One of the challenges of this disease has been to determine its prevalence. Conflicting results of the serology test in Covid explored the need for an updated meta-analysis on this issue. Thus, this systematic review aimed to estimate the prevalence of global SARS-CoV-2 serology in different populations and geographical areas. METHODS: To identify studies evaluating the seroprevalence of SARS-CoV-2, a comprehensive literature search was performed from international databases, including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL. RESULTS: In this meta-analysis, the results showed that SARS-CoV-2 seroprevalence is between 3 and 15 worldwide. In Eastern Mediterranean, the pooled estimate of seroprevalence SARS-CoV-2 was 15 (CI 95 5-29), and in Africa, the pooled estimate was 6 (CI 95 1-13). In America, the pooled estimate was 8 (CI 95 6-11), and in Europe, the pooled estimate was 5 (CI 95 4-6). Also the last region, Western Pacific, the pooled estimate was 3 (CI 95 2-4). Besides, we analyzed three of these areas separately. This analysis estimated the prevalence in subgroups such as study population, diagnostic methods, sampling methods, time, perspective, and type of the study. CONCLUSION: The present meta-analysis showed that the seroprevalence of SARS-CoV-2 has been between 3 and 15 worldwide. Even considering the low estimate of this rate and the increasing vaccination in the world, many people are still susceptible to SARS-CoV-2.
