Hong Kong tightens Russia arrival checks after plague lab worker death

Hong Kong's Centre for Health Protection is increasing health surveillance for arrivals from Russia following the pneumonia death of a lab worker at the Irkutsk Antiplague Institute. Russian authorities and WHO report no evidence of ongoing transmission, and local risk is assessed as low. The move signals precautionary public-health response to a potential plague-related incident, though details on the pathogen remain unconfirmed.
