A radio reporter from New York, US, has revealed she infected at least six people with COVID-19 at her mother's 90th birthday after spending time covering the pandemic.

Alice Stockton-Rossini, a reporter for 710 WOR, covered the coronavirus containment zone in Westchester, New York in early March and contracted the virus while doing on-mic interviews there.

She never experienced any concerning symptoms, so thought nothing of it when she hosted a birthday party for her elderly mother and 25 friends on March 8.

But Stockton-Rossini was carrying the deadly virus and unknowingly spread it to multiple other people at the party.

The party, hosted at Zion Evangelical Lutheran Church on Long Beach Island, New Jersey, saw guests greet one another with fist bumps, but that wasn't enough to protect the guests.

And just one day after the bash, Stockoton-Rossini's mum fell ill and was hospitalised. Days later, a horrified Stockton-Rossini woke with chills and a terrible realisation.

"Oh my… God. Did I bring this down here?" she remembered thinking, according to the The Philadelphia Inquirer.

She then revealed at least six people have fallen ill since the party, and two have died – one of the fatal cases was Stockton-Rossini's mother's best friend.

Sandy Medford, 76, was a close friend and neighbour to Stockton-Rossini's mother before she passed. The other fatal case was Ruth Reeder, a 96-year-old local who attended the same church.

"I can hardly bear it. I had to tell my mother her best friend died," she said.

Though Stockton has voiced her regret at ever throwing the party, which health officers confirmed was the starting point of the community outbreak, she doesn't regret covering the pandemic.

While doing her job exposed her to COVID-19, she said she'd do it over again and follow stricter rules to ensure no one else caught coronavirus from her.

"If I had to do it over again, can I honestly say I wouldn't have gone to Westchester? I probably would have worn a mask," Stockton-Rossini said.

"If I had to do it over again, do you think I'd have a party for my mother? No."

Coronavirus: What you need to know

How is coronavirus transmitted?

What are the symptoms of someone infected with coronavirus?

Coronavirus patients may experience flu like symptoms such as a fever, cough, runny nose, or shortness of breath. In more severe cases, infection can cause pneumonia with severe acute respiratory distress.

What is social distancing?

Social distancing involved minimising contact with people and maintaining a distance of over one metre between you and others.

When practicing social distancing, you should avoid public transport, limit non-essential travel, work from home and skip large gatherings.

It is okay to go outdoors. However, when you do leave home, avoid touching your face and frequently wash your hands.
