So, while it's not completely clear from the article what and how it happened, this looks like manslaughter or perhaps even murder:
A railway ticket office worker has died of coronavirus after being spat at while on duty.
Belly Mujinga, 47, was on the concourse of Victoria station in south-west London in March when a member of the public who said he had Covid-19 spat and coughed at her and a colleague. Within days of the assault, both women fell ill with the virus.
Mujinga, who had underlying respiratory problems, was admitted to Barnet hospital and put on a ventilator but died on 5 April, the TSSA union said.
The most awful story. IANAL (obv) but I doubt it could be proven that the incident was the definite cause of her infection. I'm sure I've read that coughing/spitting can be a form of assault though.

Utterly disgusting and tragic.
