Marko Petrovic was a consultant in communicable disease control in Manchester. He was born on 9 May 1963 in Manchester, the son of Serbian refugees, and studied medicine at St Bartholomew's Hospital Medical School in London, qualifying in 1986. He first trained as a surgeon and gained his FRCS in 1992. He subsequently decided to specialise in public health. He trained in Wales, where he contributed to the national response to the measles, mumps and rubella (MMR) scare. In Manchester, as a consultant in communicable disease control for Public Health England, he became an expert on tuberculosis and, with other clinicians, nurses and epidemiologists, worked to reduce the incidence of TB and improve patient care. He wrote several papers on tuberculosis and carried out research for an MD on the immunology of the disease. In the summer of 2013 he was diagnosed with an aggressive form of prostate cancer, but continued to work part time. Petrovic died on 13 March 2015, aged 51. He was survived by his wife Danica, a son, Milos, and a daughter, Jelena.
