The man had been staying at BaptistCare's Dorthy Henderson Lodge aged care centre in Macquarie Park, where an aged care worker in her 50s worked while unaware she was infected.

He is the second person to die of COVID-19 in NSW.

A 95-year-old woman who was also a resident of Dorothy Henderson Lodge, died on Tuesday and was posthumously confirmed to have been infected with the virus.

James Kwan, a 78-year-old retired travel agent, also died of the virus in Perth last Sunday morning after being a passenger on the ill-fated Diamond Princess cruise ship.

NSW chief health officer Dr Kerry Chant this morning passed on the sympathies of NSW Health to the family of the latest victim.
