JAKARTA, October 07, 2026 (DAILYNWZ) — Indonesia has tightened health surveillance at international entry points after the death of a laboratory worker in Russia from pneumonia of unknown cause, amid initial reports of a possible link to plague, state-run Antara news agency reported.
Aji Muhawarman, head of the Health Ministry’s Bureau of Communication and Public Information, said authorities were monitoring the situation closely and strengthening preparedness at airports and seaports.
So far, however, Indonesia has received no notification through the International Health Regulations National Focal Point or the World Health Organization’s Event Information Site calling for specific vigilance, Aji said.
Authorities have nevertheless stepped up checks, including at international airports and seaports in Bali, Antara reported. The measures include health declarations through the SATUSEHAT Health Pass system, symptom monitoring among travelers, risk-based assessments of incoming vessels, and surveillance of rodents and fleas.
Travelers showing symptoms such as fever, coughing or shortness of breath may be referred to designated infectious disease hospitals for isolation and treatment.
The heightened monitoring follows the death of a 28-year-old employee of Russia’s Irkutsk Anti-Plague Research Institute in Siberia.
Russian authorities have described the illness as “pneumonia of unknown etiology.” Testing found no microorganisms linked to the woman’s professional activities, according to Russian authorities, leaving the cause of the illness unresolved.
Nearly 200 people who had contact with the woman have reportedly been placed under medical observation as investigations continue.
Indonesia’s response comes despite the absence of an international alert, reflecting a precautionary approach at points of entry while authorities assess developments in Russia.
