Clinics are starting to test former hospital patients for Hepatitis C after a health worker was diagnosed with the infection.
Some 5,000 women who were linked to the worker, who has since retired, have been offered tests.
The first specialist clinic was held on Friday and 43 will be held over the next five weeks.
So far 1,400 women have contacted health officials with 1,000 test appointments made.
Two patients are known to have contracted the virus but Aneurin Bevan University Health Board, which covers the former Gwent area, said the risk of infection was low.
BBC Wales' health correspondent Owain Clarke reports.
