"I don't give a s**t who's dying," one message read out by Dr Batt-Rawden said.
Other messages included people telling healthcare workers "you chose your job, deal with it" and alleging the staff in British hospitals "don't give a damn about our lives".
One claimed that "I'm not responsible for anyone's health except my own", while another admitted they "couldn't care less who I apparently murder by not wearing a mask".
"I love the way you NHS workers think you have the right to boss us around like we're selfish for breathing," Dr Batt-Rawden read from another.
One message said healthcare workers should "f**k off and die".
"This has devastated morale," Batt-Rawden said, describing a junior doctor in the accident and emergency department telling her they were too scared to come into work because of abuse they received from virus deniers both online and off.
"That's really hard when you're actually giving your all to try and save patients on the front line when things are so difficult."
Batt-Rawden has recently begun a campaign to offset some of the abuse by encouraging people to show their support for healthcare workers online with a blue heart emoji.
She said she didn't expect the campaign to catch on but was surprised to see it trending at number one on UK Twitter.
"I did end up having a little sob," she said, adding the visible support was helping remind workers that most people are on their side.
"NHS staff really need that tidal wave of support," she said. "We just want to keep you safe, to stay at home and not end up in my intensive care unit."
