So that's 750 more people to be put at risk... Well done UK government clap clap clap. Imagine if they were Zombies
Thankfully these aren't zombies, and I suspect that military trained medics will probably be extremely careful and that 750 is from memory several times the total number of trained doctors in some of the countries.
Helping contain it now, before it spreads much further is not just good for humanitarian reasons, but extremely good in terms of practical reasons, as at the moment it's mainly hitting (massively overworked and often poorly trained/untrained) medical personal and the immediate families, with most of the victims being pretty poor/unable tor travel, but if it hits say some tourists in the area and it's not spotted until they're in say Tokyo, London, or NY it will be much much worse.
One of the main reasons it's spreading so fast in the affected areas is that there are not enough trained medical staff to deal with it, so the overworked (and poorly equipped) staff are making mistakes due to exhaustion, and family members are continuing to catch it because they're the ones looking after the sick in too many cases (meaning that the number of infections is going up rapidly, increasing the risk to everyone else and keeping the infection going).
It could also be looked as a good way to give our personal real life training to deal with it, for when (not if) we start to get the odd case in the UK - both Texas and Spain have shown their proceedures/training were not up to scratch for dealing with suspected cases (IIRC the Texas case resulted in an ambulance not being taken out of action for decontamination for several hours which could have led to a host of additional infections).
One of the big drawbacks of our modern methods of travel is that it's almost impossible to isolate an infection long enough for it to die out naturally (unlike in the past when the main method of travel was foot, horse or sailing ship, and thus taking days to travel any real distance), so assisting in controlling it whilst it's "on the other side of the world", is a very good thing to do.
