It came following social media posts claiming that St Richard’s Hospital was not struggling with an influx of coronavirus cases, accompanied by pictures of empty hospital corridors.
A spokesperson for Western Sussex Hospitals NHS Foundation Trust said: “This is untrue and highly disrespectful to all the patients and families affected by Covid, as well as our staff who are working extremely hard in very challenging circumstances.
“We must stress, pictures of empty corridors do not mean our wards and intensive care units are empty.
“For 10 months our teams have been working selflessly to care for people during the pandemic.
“This is an extremely difficult situation for us all and it is really important that we support each other and act responsibly.”
On Tuesday, the UK recorded more than 60,000 new confirmed Covid cases for the first time since the pandemic began.
