A teenager has shared footage of her family's emotional last phone call with their grandmother, shortly before she died from COVID-19.

Francesca Onorato, 16, from Natick, Massachusetts, has gone viral on TikTok, after she uploaded a video of her family speaking to her 81-year-old grandmother who had been living in a nursing home when she was diagnosed with coronavirus in April.

Speaking to Insider, Francesca revealed that her grandma Roberta was unable to respond on the phone because she was taking morphine - but the teenager said that being able to say goodbye still meant the world to the family.

'Finding out she was positive [for COVID-19] really hurt me because I realized with her lung problems, she most likely would not survive, so I was devastated,' Francesca shared.
