So breaks a test tube of live bacteria at an “anti-plague institute”, possible infects 100 colleagues, then when she developed plague like symptoms is taken to hospital and possibly infects 100 patients.
I think they need to investigate their safety protocols
> She reportedly told medical staff that she had accidentally broken a test tube containing live bacteria while collecting samples for testing.
> At least 197 people who may have had contact with her were reportedly placed under medical isolation, including more than 100 in hospital wards.
Was this a glass test tube? I understand why glass is probably the best material for the inner lining of containers that hold biological material, but I'm surprised that there aren't better solutions for hazardous material (e.g. an unbreakable, transparent polymer outer coating).
I believe the biggest reason to use glass is that it doesn't react with much stuff, but I've yet to see an explanation for why your idea wouldn't work. I imagine there could be problems with autoclaves (i.e. degradation of the polymer) and fear of chemical leaching.
Polymer coated glass is commonplace in chemistry labs for large containers of hazardous reagents held in storage. There's no chemical leaching concern because it's on the outside.
If anything, disposable plastic test tubes are the norm in microbiology labs at this point. No need to autoclave because they come sterile and you throw them away after a single use.
Plenty of plastic that's designed for it goes through the autoclave. For example micropipette tips. Nearly all of it is disposable single use so it only has to withstand a single cycle.

My guess would be cost. Glass is cheaper and with sanctions and the economic strain of war I'm sure everyone in Russia is trying to cut corners
Or a double wall - one glass one polymer
There is regular soda-lime glass and there is borosilicate glass.
Why on earth would she have contact with 197 people after she got exposed to bacteria? She should have immediately triggered safety protocols
I don't think there is any actual evidence that it was a broken test tube because she would have started on prophylactic antibiotic treatment immediately.
Luckily you need to be in close contact with someone already very sick to catch it. It's not silent transmission like COVID. But maybe there is something different about this outbreak?

What does this mean? The article we’re discussing says the woman who died told colleagues she broke a test tube.
>The article we’re discussing says the woman who died told colleagues she broke a test tube.
The article links to a telegram post [1] as source, which links to another telegram post [2], which now has an update:
>It is not known exactly how Darya Shipilova contracted the plague. Currently, the theory involving a broken test tube is the leading one, but there is no official confirmation or independent verification of this information.

That's Russia we're talking about. You can have 1000 protocols and people will ignore them anyway. You can ask a ton of questions, like was she immunized before working with plague (Russia has pretty effective vaccines against all types) and if not why the heck not, why they use easily breakable test tubes to hold dangerous pathogens, how the incident with live biomaterial was not immediately reported and caused a lockdown, but they allowed waiting for symptoms and then going to a general hospital, etc., etc. - but the answer for all of that, I suspect, is: "it's Russia". For an American, it's hard to appreciate to what measure Russia is not a "safety culture" country.

Speaking as someone who has a part of their job convincing people to follow safety processes, this isn't a Russia thing, it's a human thing.
This is a human thing, of course, but in different cultures the emphasis on following the rules and taking safety measures is different. In Russia, there isn't one.

According to aquaintances in a few different industries where some of their competition is Russian: They basically work for vodka, then their equipment breaks down, they can't fix it and the customer has to call a western company. They apparently have no consistent maintenance or service protocol whatsoever, and in some rather safety critical areas.

Irregardless of the claim of correlation, between Russia and a lack of safety culture, it is currently a country in a war economy with populace shortages.
