WHO asks Ukraine to destroy ‘high-threat pathogens’ to prevent disease spread

Biosecurity experts say Russia's attack raises risk of escape of disease-causing pathogens housed in laboratories

The World Health Organisation advised Ukraine to destroy high-threat pathogens housed in the country's public health laboratories to prevent "any potential spills" that would spread disease among the population, the agency told Reuters on Thursday.

Biosecurity experts say Russia's movement of troops into Ukraine and bombardment of its cities have raised the risk of an escape of disease-causing pathogens, should any of those facilities be damaged.

Like many other countries, Ukraine has public health laboratories researching how to mitigate the threats of dangerous diseases affecting both animals and humans including, most recently, Covid-19. Its labs have received support from the United States, the European Union and the WHO.

In response to questions from Reuters about its work with Ukraine ahead of and during Russia's invasion, the WHO said in an email that it has collaborated with Ukrainian public health labs for several years to promote security practices that help prevent "accidental or deliberate release of pathogens".

"As part of this work, WHO has strongly recommended to the Ministry of Health in Ukraine and other responsible bodies to destroy high-threat pathogens to prevent any potential spills," the WHO, a United Nations agency, said.

The WHO would not say when it had made the recommendation nor did it provide specifics about the kinds of pathogens or toxins housed in Ukraine's laboratories. The agency also did not answer questions about whether its recommendations were followed.

Ukrainian officials in Kyiv and at their embassy in Washington did not respond to requests for comment.

Ukraine's laboratory capabilities are at the centre of a growing information war since Russia began moving troops into Ukraine two weeks ago.

On Wednesday, Russian foreign ministry spokesperson Maria Zakharova repeated a longstanding claim that the United States operates a biowarfare lab in Ukraine, an accusation that has been repeatedly denied by Washington and Kyiv.

Zakharova said that documents unearthed by Russian forces in Ukraine showed "an emergency attempt to erase evidence of military biological programmes" by destroying lab samples.

Reuters was unable to independently confirm her information.

In response, a Ukrainian presidential spokesperson said: "Ukraine strictly denies any such allegation." US government spokespeople also strongly denied Zakharova's accusations, saying that Russia may use its claims as a pretext to deploy its own chemical or biological weapons.

The WHO statement made no reference to biowarfare. The agency said it encourages all parties to cooperate in "the safe and secure disposal of any pathogens they come across, and to reach out for technical assistance as needed." It offered to help wherever possible with technical guidance and coordination.

The United Nations Security Council will convene on Friday at Russia's request, diplomats said, to discuss Moscow's claims, presented without evidence, of US biological activities in Ukraine.
