my point only is to make it mandatory for expats (to the company's expense) for an annual medical check-up to check any medical problem an expat may get while on emplyment here.  So it could be remedied at once. Rather than being sick first before going for check-up, why not make it mandatory again.  

As for the locals, once someone or somebody dies of such a disease, then they will realise the imporatnce of early detection and cure if ever!
