Whether you are susceptible to recurrent cold sores or carry the virus but are never symptomatic, can be down to genes,
reveals O'mahony.
Increasing international evidence demonstrates that leaders can significantly improve the performance of their organisations and communities through coaching and mentoring(for example,
Barnett and O'mahony, 2006).
According to the HVA, other common reasons for recurrences include stress, illness,
alcohol and having a period, although O'mahony suggests there is no evidence for an increased risk with hormone fluctuations,
the contraceptive pill, or pregnancy.
