Department of health fitting the bill for expats getting a serious illness

The department of agriculture and labour allows south Africans to go and work in Zambia with promise's of a tax free salary and benefits IE medical insurance but in some cases there is no salary and benefits and once a person gets ill they are sent back with, in this case, malaria - the department of health is struggling as it is and now they must with out knowing prepare for south african Expats that was infected with malaria and sent home with no pay or benifits, fit the bill instead of the employer taking responsibility for anything. How can this be possible, and how can your life insurance be held responsible to act on your behalf, sars gets no money they employee gets no salary, they get a very serious illness and government must fit the bill???
