Alex Duval is a healthcare assistant who worked at Holby City Hospital from 2020 to 2021. He is the brother of general surgeon Xavier "Zav" Duval.


In July 2020, during the height of the COVID-19 pandemic, Alex decided to volunteer at Holby City Hospital. Donna initially felt uneasy about Alex's presence at the hospital, but she was touched when Alex used his money from Zav to buy additional PPE for her and the other staff. (HC: Episode 1034) After the peak of the pandemic had passed, Alex applied to become a healthcare assistant at the hospital and was ultimately given the job. However, Donna took issue with not being informed about Alex's employment and tried to avoid him throughout the day. After Donna apologised and explained that she had a lot on her mind, Alex offered himself up for a talk "as friends", but Donna asserted that they would be inappropriate for them to be friends. (HC: Episode 1036)
