The virus had been undiagnosed for 30 years.
Known as the "silent killer", hep C may cause few symptoms initially, with early signs including night sweats, brain fog, itchy skin and fatigue.
But for every year a person carries the virus, their chance of dying from liver cirrhosis and related cancers increases.
Meagan, who is now 28, says her father was angry that it had taken so long to get a diagnosis.
"I also felt at the time he felt a little bit of shame too, he didn't want anyone to know, just wanted to keep it to himself, but mostly angry, we all were," she says.
Campbell died in 2024, at the age of 61, just five years after finding out he had the disease.
"Over those last few years he wasn't himself," Maegan says.
"He wasn't the dad that I knew. He had a lot of brain fog, it affected him, it affected his personality."
Maegan wonders what their relationship might have been, had they known Campbell was genuinely very ill.
"I feel a lot of guilt a lot," she says.
"If I'd known then, what I know now, I think our relationship would have been a lot different.
"I myself have suffered a lot of mental health problems because of the breakdown of my relationship with my dad. I wish I'd been there for him now."
