What kinds of security failures were the cables describing?
The short answer is we don't know from the information provided in
the Washington Post. But, generally speaking, there are multiple ways
that safety measures can be breached at labs dealing with biological
agents.
According to Dr Lentzos, these include: "Who has access to the lab,
the training and refresher-training of scientists and technicians,
procedures for record-keeping, signage, inventory lists of pathogens,
accident notification practices, emergency procedures."
Dr Lentzos said the issue of the virus' origin was a "very difficult
question", and added that "there have been quiet, behind-the-scene
discussions... in the biosecurity expert community, questioning the
seafood market origin that has come out very strongly from China".
Amid this war of words between the countries, the painstaking - and
largely unseen - scientific work to trace the origin of the virus will
continue.
