Samantha Morton has revealed she was rushed to hospital on Monday night.

The actress, 43, took to Twitter to urge her followers to ‘wear a mask’ as England was plunged into another COVID-19 lockdown, adding that she was ‘humbled’ seeing the work done by NHS staff first-hand.

Samantha’s representative went later told MailOnline she was admitted after suffering an anaphylactic shock. The star went onto reassure fans she was ‘on the mend’ as she thanked them for their messages of support.

In the early hours of Tuesday morning, Samantha posted: ‘Thank you to all the A and E staff at the Conquest who helped me tonight.

‘I’m so grateful for our NHS,to see the red zone first hand and the nurses and doctors being so kind and wonderful to us all was humbling. I’m OK tonight because of them.’

The red zone is typically used to described hospital wards that are used to treat COVID-19 patients.

Samantha returned to Twitter minutes later to add: ‘I’m on the mend. I’ll get there and thank you so much for the well wishes #SaveOurNHS #WearAMask.’

She also posted a snap of her face covered with a mask and shield while sitting in the hospital ward.

In a statement Samantha’s representative said: ‘Samantha Morton suffered an anaphylactic shock last night and so attended A+E at the Conquest Hospital.

‘Because her temperature was so high and she was having difficulty breathing she was placed on a Covid ward for several hours where she witnessed the current shocking situation in our hospitals first hand.

‘Samantha would just like to send her thanks and absolute admiration to all the NHS staff who are doing such an incredible job under the most distressing circumstances. Samantha is now home with her family recovering.’

Her hospitalisation comes just hours after Prime Minister Boris Johnson announced England would be placed in a third coronavirus lockdown, following a huge rise in cases over the Christmas and New Year period.

New restrictions include a ban on households mixing, closing non-essential business and the closure of schools, colleges and universities.
