A community has raised £11,000 for a young girl who suffered from a very rare genetic disease, had a bone marrow transplant and spent about 10 months in isolation.

Olivia Hollywood-MacNamara, 9, from Stoneleigh Broadway, was diagnosed with chronic granulomatous disease (CGD), which affects the immune system, just after Christmas 2012.

The condition, which affects about only four to six people in every million in the UK, meant she had to spend 10 months in isolation.

Following a bone marrow transplant last October, Olivia has now been cured of the disease, came out of isolation in June and is looking forward to going back to Meadow Primary School in September.

A fundraising night and raffle, plus individual donations, have helped to raise money to take her on trips and outings when she is feeling stronger.

Olivia’s mother Wendy, 37, said she got the green light and came out of isolation just before the event organised by a family-run business located below their home, Classic Home Care Services.

Mrs Hollywood-MacNamara said: "There were all these people there for her. I don’t think she knew what to do with herself. We couldn’t believe the generosity. It’s unbelievable what people have done."

She also thanked the director’s friend Clive Hagley and his son Max who raised £2,400 by trekking to Everest base camp in April.

The family plans to spend the money on a holiday and a pass which will give them free entry to theme parks, aquariums and other attractions.

She said: "On the weekends for a long time we have been at home. We didn’t go anywhere we didn’t do anything."

She added: "Because Olivia had been inside for so long she struggled when she was allowed to go out because she was not used to the noise and lots of people. She was a bit frightened to be honest."

Olivia was the first person to be diagnosed with CGD at Epsom Hospital. Mrs Hollywood-MacNamara said: "It was such a shock. We never expected it at the time."

Jenny Redwood, director of Classic Home Care Services, said: "My friend Clive was climbing to base camp (Mount Everest) in April and we discussed with the family using Clive's climb as a way of fundraising for Olivia to have days out with her family when she was feeling stronger.

"As Olivia is a local child we felt it was important to give something back to a local child.

"We held a fundraising night in La Familia restaurant in Ewell, this is where most of the money was raised through raffles and an auction. Most of the local businesses in Stoneleigh & Ewell gave items for the raffle."
