China confirms unauthorised labs were told to destroy early coronavirus samples

HONG KONG — China on Friday (May 15) confirmed it had ordered unauthorised laboratories to destroy samples of the new coronavirus in the early stage of the outbreak, but said it was done for biosafety reasons.

HONG KONG — China on Friday (May 15) confirmed it had ordered unauthorised laboratories to destroy samples of the new coronavirus in the early stage of the outbreak, but said it was done for biosafety reasons.

US Secretary of State Mike Pompeo has repeatedly said that Beijing declined to provide virus samples taken from patients when the contagion began in China late last year, and that Chinese authorities had destroyed early samples.

Mr Liu Dengfeng, an official with the National Health Commission’s science and education department, said this was done at unauthorised labs to “prevent the risk to laboratory biological safety and prevent secondary disasters caused by unidentified pathogens”.

“The remarks made by some US officials were taken out of context and intended to confuse,” he said at a briefing in Beijing.

When the pneumonia-like illness was first reported in Wuhan, “national-level professional institutes” were working to identify the pathogen that was causing it, Mr Liu said.

“Based on comprehensive research and expert opinion, we decided to temporarily manage the pathogen causing the pneumonia as Class II — highly pathogenic — and imposed biosafety requirements on sample collection, transport and experimental activities, as well as destroying the samples,” he said.

Mr Liu added that this was in line with China’s standard practice for handling highly pathogenic samples, which should not be done by labs that do not meet the requirements.

Class II pathogens can be transmitted among humans or animals, or between humans and animals, and cause serious diseases such as severe acute respiratory syndrome (Sars) and smallpox.

Tensions have escalated between Beijing and Washington as they trade accusations over the origin of the virus, which has killed more than 300,000 people worldwide, and China is under mounting international pressure to allow an inquiry into its handling of the pandemic.

According to a provincial health commission notice issued in February, those handling virus samples were ordered not to provide them to any institutions or labs without approval. Unauthorised labs that obtained samples in the early stage of the outbreak had to destroy them or send them to a municipal centre for disease control and prevention for storage.

Chinese magazine Caixin reported in February that some hospitals had sent samples to private gene sequencing companies to identify the mystery virus early in the outbreak. Some of those results came back as early as December 27 and were identified as being from the same coronavirus family as Sars, the report said. One company had been told to destroy all virus samples, according to the report.

The National Health Commission started investigating the virus on December 31 and informed the World Health Organisation of the outbreak the same day. On January 3, it ruled out that the virus was a known pathogen causing respiratory disease, and on January 9, it said the illness was caused by a novel coronavirus. It was later named Sars-CoV-2, and the disease it causes Covid-19.

Both US president Donald Trump and Mr Pompeo have accused China of cover-ups and missteps at the start of the outbreak, and Mr Pompeo has said Beijing withheld early samples that could have been used to develop a vaccine.

On Friday, Mr Liu said China had shared viral strains of influenza in the past and was open to sharing samples of Sars-CoV-2 “in an orderly manner within the framework of the World Health Organisation (WHO)” to “further strengthen international cooperation and scientific research, promote the development, production and fair distribution of Covid-19 vaccines, diagnostic tools and therapeutic drugs”.

The health commission also rejected claims by US officials that China denied a request by the WHO to visit the high-security Wuhan Institute of Virology, which is at the centre of conspiracy theories that the virus was engineered or escaped from the lab.

Li Mingzhu, a senior official with the health commission’s international cooperation department, said the WHO did not make any request to visit the lab during two trips to Wuhan, in January and February.

“The WHO has never made a request to visit a certain laboratory, so the statement that the WHO was denied a visit to the Wuhan laboratory is untrue,” Mr Li said. SOUTH CHINA MORNING POST
