Carol, from Bury in Greater Manchester, who had asthma, became suddenly unwell at her home and then rushed to hospital.
Her nephew, Dakuro Fiberesima, from Purfleet, Essex, said she was put on a ventilator at Salford Royal Hospital but could not be saved.
Dakuro added: “It happened so rapidly. No one was by her side. With the ventilator decision, you just get a call they are planning to turn the ventilator off. She was an amazing aunt. She was fun and had such a positive character.”
A second carer, Catherine Sweeney, from Dumbarton, has also been named as having died.
Her family said: “She was a caring and generous person, especially when it came to her time, having dedicated over 20 years of her life as a home carer to unfailingly serve the needs of the most vulnerable in society.”

Tamira Harvey, whose dad Thomas, a mental health nurse for 20 years in North London, died from the virus, says he did not have adequate PPE.
She added: “My dad was let down. The Government could have prevented this.”
Nurse Aimee O’Rourke, 39, died at the hospital where she worked – Queen Elizabeth the Queen Mother Hospital in Margate, Kent – after testing positive for Covid-19. She came to the profession after raising three girls.
Among the other victims are Professor Sami Shousha, 79, who had worked at cancer research labs in London and Dr Alfa Saadu, 68, who retired but carried on part-time at the Queen Victoria Memorial Hospital in Welwyn, Herts.
Organ transplant specialist Dr Adil El Tayar, 63, was the first working NHS surgeon to die from coronavirus in Britain. Many other essential workers have died too.
