Turkish police have launched an investigation into online adverts posted by people allegedly so desperate for money they are offering to sell their kidneys, local media reported Monday.

Hong Kong on Monday confirmed its first human case of the deadly H7N9 bird flu, according to a report, in the latest sign of the virus spreading beyond mainland China.

South Africa has been hailed as a model for HIV treatment, but some now fear its very success may be breeding complacency and making people less careful about infection.
