Introduction: The migratory flow of foreign people implies a greater risk of spreading SARS CoV2 in the national territory. In Colombia, from March 2020 to October 31, 2021, there were 67 787 confirmed cases in the foreign population.
Materials and methods: Observational cross-sectional study, with primary data source from the Public Health Surveillance System (Sivigila) from March 2020 to October 2021. Central tendency measures and dispersion were calculated, the mean and standard deviation for quantitative variables were calculated and proportions for qualitative variables. Univariate and bivariate analyzes were performed, and the odds ratio between history, comorbidities, age, and sex were estimated. P<0.05 values were considered statistically significant. Spatial analysis was carried out to identify territorial entities at risk and the origin of the imported cases.
Results: 67 893 cases of COVID 19 corresponded to foreign population captured by the nationality variable in Sivigila. The average age was 35,8 ±15,8 (Me=33), the minimum age was 0 years, and the maximum was 114 years. The variability was heterogeneous (CV=42,81 %). The predominant sex was male in 51,9% (n=35 203), female 48,1% (n=32 690). The city with most cases corresponds to Bogotá with 49.8% of the cases (n=33 868), followed by Antioquia with 19,73 % (n=13 398), Valle del Cauca with 5,64 % (n=3,827) and Norte de Santander with 3,89 % (n= 2 640), Barranquilla with 3,09 % (n=2 098).
Conclusion: In the foreign population, the number of cases is higher in men, with ages between 30 to 39 and 20 to 29. Deaths were identified as having an association with HIV and smoking comorbidities.
