Rico has lived with HIV for almost a decade, confiding in only a small number of people in socially conservative Singapore, fearful of the reaction. Last month, he got a phone call saying information about his condition had been published online. Rico was one of 14,200 people whose HIV status, name and address were dumped on the internet by an American man who is believed to have obtained the confidential data from his partner — a senior Singaporean doctor. “The LGBT community is angry and frustrated with the entire ordeal,” said Rico, who did not want to be identified by his full name.
