A tuberculosis outbreak among North Korean workers in northeastern China has exposed serious flaws in pre-departure health screenings. Approximately 35,000 North Koreans entered China between early this year and the end of last month, and they began work in garment, food, and seafood factories across Liaoning and Jilin provinces. Early this month, three workers at a Liaoning garment factory tested positive for pulmonary tuberculosis and authorities quickly repatriated them. The workers had developed fevers and persistent coughs within weeks of their arrival, and local hospitals confirmed the diagnosis.
The factory employed around 300 North Korean laborers at the time. Consequently, other Chinese factories with North Korean staff conducted emergency health checks and found five more tuberculosis cases at an additional facility. Managers immediately isolated those workers and sent them back to North Korea within days. Pulmonary tuberculosis spreads easily through respiratory droplets, and the communal dormitories where workers live create ideal conditions for rapid transmission. Factory managers and Chinese staff have now started wearing masks as a precaution, and anxiety has visibly increased.
Despite the infections, the flow of workers has not stopped. Buses carrying North Koreans continue crossing from Sinuiju into Dandong at a rate of dozens per day. The workers reportedly underwent health screenings, including tuberculosis checks, before leaving North Korea. However, the source indicated those screenings were likely a mere formality or conducted with inadequate equipment. North Korea’s healthcare infrastructure often lacks the chest X-rays and sputum tests needed to reliably diagnose active tuberculosis, and the accuracy of testing appears significantly compromised.
North Korea resumed large-scale overseas labor deployments after lifting pandemic-era border restrictions in 2023. The program remains a crucial source of foreign currency, with workers’ wages largely remitted directly to the government. Meanwhile, the continuing influx highlights the priority Pyongyang places on revenue, even as the tuberculosis outbreak raises public health concerns. Nevertheless, the tuberculosis outbreak has not prompted any immediate halt to the labor deployments. Chinese employers have grown anxious, yet the pipeline persists without interruption. For now, the tuberculosis outbreak underscores the risks of relying on health checks conducted under severe resource constraints. The situation has prompted calls for more rigorous screening and monitoring of foreign workers, but no immediate policy changes have emerged.
