to criminal prosecution. One such case is that of Thomas Guerra, an American landscape architect, who became the first person in the state of California to be convicted for intentionally infecting another individual with HIV. In court, prosecutors presented 11,000 text messages and 36 audio clips to support their case against Guerra. Since then, Guerra has been accused of intentionally exposing dozens of other men to HIV. In a 2004 survey of the latter group, the Global Network of People Living with HIV/AIDS found that at least one prosecution had occurred in about half of these countries, and that in Finland, Sweden and Slovakia, about 0.5% to 1% of all people reported to be living with HIV/AIDS had been prosecuted for alleged intentional or "negligent" transmission of HIV. In many developing countries such as Thailand where the HIV/AIDS pandemic has been much more serious, laws regarding criminalisation of intentional transmission have been either weak or non-existent. From a global perspective, the U.S. and Canada account for the vast majority of reported prosecutions. Australia In Australia the regulations concerned with the transmission of HIV are found in two sources, the Public Healths Acts and in the criminal law. New South Wales The New South Wales (NSW) Public Health Act from 2010 regulates under section 79 that a person with HIV must disclose their status to all sexual partners. Under section 79(3) it is a defence, if the court is satisfied, that the defendant took reasonable precautions to prevent the transmission. In other Australian states, there is no specific legislative requirement to disclose. Interventions may range from counseling through to restrictive orders, with detention as a last resort. If talking about the problems of practising safe sex does not help, the doctor may obtain a Public Health Order to manage the behaviour of the HIV positive person. Only a small number of sex workers and clients have received a Public Health Order or 'management' intervention for potentially breaking the law. Under the criminal law, a person with HIV is criminally liable for prosecution if they have intentionally transmitted the virus to their partner without informing them of their status. In NSW the relevant offences are separated into those done intentionally (s. 33 of the Crimes Act 1900), and those done recklessly (s. 35). The definition of grievous bodily harm (GBH) now explicitly includes (in ss. 4(1)(c)) 'any grievous bodily disease'. This means
