It's all very well saying the staff should be quarantined, but there's still flights arriving every day from China and other heavily infected areas, and the majority of passengers arriving from there (Wuhan excepted) aren't being quarantined. Surely this is a much higher risk?
No its not.
The nurses in question are KNOWN to have had close contact with a known case. Medics because of the nature of their job are KNOWN to be at higher risk of infection of rare diseases.
Also being quarantined means you are under observation. From a Health and Safety point of view this is your employer looking out for you and making sure if you do have the disease they spot it at the earliest opportunity for your own benefit.
Outside Hubei province, the number of cases and infections is much much lower. Statistically speaking people coming from China and other places in Asia are less likely to have been in direct contact with someone infected. Plus many airlines have already stopped flights to and from China.
The thing is though, if staff genuinely think that by going to work there's a risk they won't be allowed home again, a large number of staff are just going to start refusing to go to work. And then what happens? For some people not being allowed home just isn't an option. What if you are a lone parent for example?
So quit being a nurse and get another job to pay your bills. It'd be a nice position to be in to just refuse to turn up for work but expect the bills to get paid.
There is always a risk of working in healthcare that you could be exposed to an illness or incident that could affect your health in someway either deliberately or accidently, and that might require you to be quarantined or otherwise hospitalised. Thats the nature of the job. Its extremely unusual but still possible.
If legally you are detained / incapacitated then the state would have a duty of care to provide emergency child care for any dependants you have.
The idea that large numbers of workers are going to go on strike if faced with a situation like this is laughable.
