Objectives: This study was conducted to determine the incidence and risk factors of myocardial infarction (MI) and stroke in farmers compared to the general population and to establish 5-year prediction models. Methods: The farmer cohort and the control cohort were generated using the customized database of the National Health Insurance Service of Korea database and the National Sample Cohort, respectively. The participants were followed from the day of the index general health examination until the events of MI, stroke, or death (up to 5 years). Results: In total, 734 744 participants from the farmer cohort and 238 311 from the control cohort aged between 40 and 70 were included. The age-adjusted incidence of MI was 0.766 and 0.585 per 1000 person-years in the farmer and control cohorts, respectively. That of stroke was 0.559 and 0.321 per 1000 person-years in both cohorts, respectively. In farmers, the risk factors for MI included male sex, age, personal history of hypertension, diabetes, current smoking, creatinine, metabolic syndrome components (blood pressure, triglycerides, and high-density lipoprotein cholesterol). Those for stroke included male sex, age, personal history of hypertension, diabetes, current smoking, high γ-glutamyl transferase, and metabolic syndrome components (blood pressure, triglycerides, and high-density lipoprotein cholesterol). The prediction model showed an area under the receiver operating characteristic curve of 0.735 and 0.760 for MI and stroke, respectively, in the farmer cohort. Conclusions Farmers had a higher age-adjusted incidence of MI and stroke. They also showed distinct patterns in cardiovascular risk factors compared to the general population.

Background: The quarantine process at a country's port of entry has an important role in preventing an influx of coronavirus disease 2019 (COVID-19) cases from abroad and further minimizing the national healthcare burden of COVID-19. However, there has been little published on the process of COVID-19 screening among travelers entering into a country.Identifying the characteristics of COVID-19 infected travelers could help attenuate the further spread of the disease. Methods: The authors analyzed epidemiological investigation forms and real-time polymerase chain reaction (PCR) results for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) of entrants to Incheon International Airport between March 11 to April 30, 2020. We performed univariate and multivariate logistic regression analysis to determine the odds of positive SARS-CoV-2 result. Results: A total of 11,074 entrants underwent reverse-transcription PCR for SARS-CoV-2, resulting 388 confirmed cases of COVID-19 infection. COVID-19 had a strong association with the reported loss of smell or taste and association with self-reported fever, chill, cough, and vomiting. If a traveler reported contact with an individual with either respiratory symptoms or confirmed COVID-19 in the last two weeks directly prior to landing, the probability of a positive result was increased. Conclusion If overseas travelers experience loss of smell or taste in the two weeks prior to arrival, they may require an immediate examination to rule out COVID-19 at a port of entry. As to measure body temperature upon arrival at a port of entry, it is important to screen for any occurrence of fever within the two weeks prior to travel. Also, information with epidemiological relevance, such as recent contact with an individual suffering from any respiratory symptoms or with confirmed COVID-19, should be included in COVID-19 screening questionnaires for international travelers.
