Health plays a key role in sustainable development, but emerging markets and developing countries have much catching up to do in the public healthcare arena, moreover in most the coverage provided by health insurance schemes is inadequate. Two factors are helping to improve the situation: an expanding middle class who can afford more to spend on healthcare and a higher level of government investment in public health services. Healthcare companies working in pharmaceuticals, health services and medical technology will benefit from soaring demand. Emerging markets will account for half of global growth in demand for pharmaceutical products up to 2015.
