Shocking footage appeared to show a young woman laughing after she coughs near a couple standing in a supermarket queue.
The woman appears to initially cough without covering her mouth outside the shop in north Kildare, Ireland.
In the video, the couple can be seen looking back, unimpressed.
Footage of the incident was posted on social media site TikTok and was also shared on Twitter, Dublin Live reports.
Her actions have been slammed by social media users who didn't find anything to laugh about.
One user said "How is that funny?" while another added: "Trying to get a few likes on an app just so she can feel like she is somebody and can fit in... Another muppet."
Almost 200,000 people have died from COVID-19 worldwide during the global pandemic.
Today a further 52 people died in Ireland, taking the total number of deaths there to 1,063.
Officials noted 377 new confirmed cases, meaning a total of 18,561 confirmed cases of the virus in Ireland.
In spite of the deadly serious nature of the live-threatening disease, some sickening challenges have emerged on social media.
Last month, a man who filmed himself licking a toilet bowel as part of the "corona challenge" later contracted the deadly bug.
The so-called challenge - which sees people share videos online of themselves licking objects in public places - has been slammed as "highly irresponsible" by health experts.
Shocking videos have been shared across various social media platforms in direct contradiction to official advice to stop the spread of the potentially fatal virus.
The craze began after a TikTok influencer shared a clip of herself licking an plane toilet seat as someone says "it's corona time".
She told Metro : "I was tired of that b***h corona getting more publicity than ME. I’m the real celebrity."
The woman, who the news platform chose not to name, said health experts "can suck it" and claimed "I'm fine".
She went on to say if her actions lead to other people becoming ill with the deadly virus "that's their problem".
In another upload a man licks a pole on public transport to the disgust of another who moves away, while a further video sees a man - whose Twitter account has now been suspended - licking a public toilet seat.
Metro reports TikTok has confirmed it will remove all challenge content from the site.
A TiKTok spokesperson said the challenge content is a "violation of our guidelines" and vowed to remove any reported content.
Gardai said they have not received any reports about the latest shocking incident but have reiterated their appeal to anyone who has been the victim of such attacks to report it to them.
A garda spokesman said: "Any incident of coughing or spitting could amount to an offence under the Public Order Act or Non-Fatal Offences Against the Person Act.
"An Garda Síochána is treating any reports of this type of activity seriously and where suspected offenders are identified they will be arrested and brought before the courts.
"An Garda Síochána asks anyone subject to this type of behaviour to report it to An Garda Síochána directly and not on social media."
