Hong Kong has stepped up health checks on travellers arriving from Russia after the unexplained death of a laboratory worker at a Siberian anti-plague institute. It is the first control measure announced by a Chinese government body in response to the case.

The city's Centre for Health Protection (CHP) said on Monday that the "immediate public health impact to Hong Kong is low." It said it had acted "for the sake of prudence."

The background

Darya Shipilova, 28, a worker at the Irkutsk Anti-Plague Research Institute, died on 2 October after severe pneumonia. Russia has told the World Health Organization (WHO) her death "was not due to plague infection." In its Disease Outbreak News notice of 10 October, the WHO said it has not been told what caused her illness and that "a laboratory-associated exposure therefore cannot be fully excluded at this stage." It found no evidence of ongoing transmission and advises no travel or trade restrictions.

Hong Kong: airport checks

The CHP said it will:

  • have Port Health officers take temperatures at the gates of "relevant flights from Russia" and assess passengers with symptoms;
  • use airport signs, announcements and airlines to ask anyone who has been in Irkutsk Oblast in the past 14 days to declare it;
  • send arriving travellers with pneumonia symptoms to a public hospital for testing;
  • write to all doctors and hospitals. Any patient with pneumonia of undetermined cause who visited Irkutsk Oblast within 14 days of falling ill "must immediately report to the CHP."

The CHP said it has had no reports in recent months of travellers from Russia arriving with unexplained pneumonia. The South China Morning Post and RTHK, with Reuters, reported the measures.

Mainland China: local notices, not national rules

On the mainland, the measures found so far are local and advisory. No notice from China's National Health Commission, the Chinese Center for Disease Control and Prevention or the customs administration has been found.

Hulunbuir, Inner Mongolia. The city's disease-control centre issued a plague "risk notice" that names the Irkutsk death, according to the local outlet Hulunbuir Rongmei. The Inner Mongolia Communist Youth League later reposted it on Weibo. The notice says Hulunbuir, which borders the Russian Far East, has had no human plague case since 1927. It has found no plague among rodents in recent years and rates the chance of an outbreak as "low." It advises people arriving from plague-focus areas of the Russian Far East to watch their health and to tell doctors their travel history if symptoms appear. "There is no need for excessive panic," it says.

Manzhouli. The border city's disease-control centre held a risk-assessment meeting on 8 October that focused on the Irkutsk case, according to Malaysia's e-Nanyang and other outlets citing the centre. The meeting concluded that the risk of the illness being brought in across the border "still exists." It called for stronger surveillance and coordination with ports and customs.

Hunan and Guangdong. Hunan's provincial disease-control authority published a health reminder on 9 October that cites the Russian case, Radio Free Asia (RFA) reported. It said the province has no natural plague-focus areas and that everyday risk is very low. Guangdong's disease-control authority published a general plague explainer the same day. RFA said the visible content of that explainer does not mention the Russian event.

Taiwan

Taiwan's Centers for Disease Control said it asked the WHO about the case on 6 October through International Health Regulations channels and published the reply on 8 October. It said it has strengthened fever screening at airports and ports and is asking passengers who transited through Russia about their travel. "Please do not panic excessively," it said.

Markets and pharmacies

Shares in North China Pharmaceutical hit their daily limit again on Monday, according to the financial site Yuncaijing. They are up 33 per cent since 30 September. The company issued a risk warning saying its operations are normal.

Earlier, the China-Global South Project reported that many doxycycline listings on Chinese e-commerce sites were out of stock, and that posts such as "COVID also began as pneumonia of unknown cause" trended on Weibo. A later check by the Phoenix (ifeng) platform found doxycycline supply "generally stable." A doctor quoted there warned that healthy people taking antibiotics as prevention is "a serious mistake."

A plague expert's view

In Tablet magazine, Stanford plague expert David Relman said the most plausible explanation was an accidental lab exposure that Shipilova did not recognise at the time. He called other scenarios, such as an engineered strain, speculation. "There are so many things in what we've heard so far," he said, "that just don't hang together."

The institute's silence

The Siberian outlet Lyudi Baikala reported that the institute has still not posted any notice of Shipilova's death on its website. It also reported that an international plague conference it is hosting on 21–22 October is going ahead under a 13.15-million-ruble contract, with no public announcement of a cancellation.

Rumours, labelled

  • A "third case": Posts on X claim a third person died and that Russia is covering it up. No evidence has been offered, and Russia denies even a second case.
  • Suifenhe "closed": An image claiming the Suifenhe border port had closed circulated on Chinese social media around 11 October. RFA reported on 8 October that Suifenhe's disease-control centre was running public-education campaigns, not new controls. No closure has been announced.
  • "China closed or tightened its border with Russia": No national border or customs measure has been found. The documented steps are local notices and the Manzhouli meeting.
  • Stockpiling and lockdowns: Viral posts urged residents of northeast China to stockpile food, masks and antibiotics. Mass buying in those provinces has not been shown, and no lockdown has been announced.

What is still unknown

  • What caused Shipilova's pneumonia
  • Whether Beijing will issue any national guidance
  • Whether Hong Kong's checks have flagged any travellers
  • Whether the Irkutsk conference will go ahead as planned
