A loophole in the UK National Health Service's policy banning recruitment of health care workers from developing countries has led to the hiring of thousands of nurses and midwives from such countries and is damaging the global fight against HIV/AIDS and other diseases, Andrew George, a member of Parliament from the minority Liberal Democrat party, said on Monday, London's Guardian reports. George said nurses and midwives are being brought from developing countries to work in the United Kingdom through a loophole in the ban that allows them to work for a short time at a private facility before being hired by the government.
