Is burgeoning, but at the cost of public health care

While the current Ebola epidemic spiraled out of control to become the biggest in history, the global public health response has been criticized as "too little, too late." Many, like the World Health Organization, are asking what lessons have been learned from this epidemic. We present an analysis of the political economy of this Ebola outbreak that reveals the importance of addressing the social determinants that facilitated the exposure of populations, previously unaffected by Ebola Virus Disease, to infection and restricted the capacity for an effective medical response. To prevent further such crises, the global public health community has a responsibility to advocate for health system investment and development and for fundamental pro-poor changes to economic and power relations in the region.

The medical tourism sector in India has attracted global attention, given its phenomenal growth in the past decade. India is second only to Thailand in the number of medical tourists that it attracts every year. Estimates indicate that the medical tourism market in India could grow from $310 million in 2005 to $2 billion by 2012. These figures are significant when contrasted with India's overall health care expenditure - $10 billion in the public sector and $50 billion in the private sector. Factors that have contributed to this growth include the relative proficiency in English among health care providers and the cost effectiveness of medical procedures in India. Generally, most procedures in Indian hospitals cost a quarter (or less) of what they would cost in developed countries. The expansion of medical tourism has also been fueled by the growth of the private medical sector in India, a consequence of the neglect of public health by the government. India has one of the poorest records in the world regarding public financing and provisioning of health care. A growing driver of medical tourism is the attraction of facilities in India that offer access to assisted reproductive care technologies. Ironically, this is in sharp contrast with the acute neglect of the health care needs of Indian women. The Indian government is vigorously promoting medical tourism by providing tax concessions and by creating an environment enabling it to thrive. However, there is a distinct disjunction between the neglect of the health care needs of ordinary Indians and public policy that today subsidizes the health care of wealthy foreigners.

Membrane technology is a growing alternative for ammonia removal and recovery from wastewater compared to many other water treatment processes, such as strippers, scrubbers, and deaeration systems. Among the available alternatives, the TransMembraneChemiSorption (TMCS) has been gaining consideration, especially under certain operating conditions. TMCS using a membrane contactor is a unique separation process that is transitioning from research and pilot phases to field installations. This paper reviews the results of such an ammonia removal system using membrane contactors.
