Claudia Marsh died at the Royal University Hospital on her 25th birthday after contracting the virus.
Ms Marsh was also an active charity volunteer, working with Talking Eating Disorders (TEDS) and homelessness organisation The Whitechapel Centre in Merseyside.
On a fundraising page Claudia's family asked mourners to donate to the two charities in lieu of sending flowers.
A description for the page reads: "In loving memory of our beautiful daughter and incredible sister, Claudia, who passed away at The Royal University Hospital, Liverpool, on her 25th birthday after succumbing to Covid-19.
"In lieu of the family receiving flowers we would like to ask for donations towards two charities that Claudia was involved with and supported."

The page set a target of £500 - but had already reached £14,970 by the time of writing.
Family friend Leigh Best, who founded TEDS, described the death as "heartbreaking" to the BBC.
She added: "Claudia was very special, kind, caring and a dedicated teacher.
"She supported countless families across the UK. Claudia made her own little packs to give out to others with eating disorders with positive affirmations.
"She was full of positivity, kindness and hope, and had a smile that would brighten up the whole room."
