t during surgery in 1983 but unaware of his illness for a decade, said he felt sorrow rather than guilt for apparently passing the virus to a woman during an operation in 1992. "I`m not to blame. No, no, no," he told RTL radio. He believes he both got the virus and passed it on by accidentally slicing through protective gloves with his scalpel, mixing his blood with that of the patient in the operating theatre. Cohen, formerly an orthopaedic surgeon, said that anyone entering hospital for surgery "should be tested. It`s very quick. It`s very reliable." A positive test would mean health workers would take extra care. The French Health Ministry, which announced two weeks ago that Cohen had apparently infected a patient, opposes blanket testing because it could delay operations and cause more deaths than it saved. Cohen, who worked at Saint-Germain-en-Laye hospital near Paris, is believed to be the second health worker in the world to have infected a patient. The other was a Florida dentist, David Acer, who died of AIDS in 1990 after infecting six of his patients. Cohen said he did not want to telephone the woman he inadvertently infected, even though he said she was hoping for a call. He said that telephoning her would aggravate tensions within his family. "It`s psychologically very hard," he said.
