Coronation Street actress Sue Cleaver, who plays Eileen Grimshaw in the award-winning ITV soap, has been admitted to hospital after contracting a mystery illness whilst filming in Kenya.

Cleaver had been over in Kenya taking part in a documentary called Corrie Goes To Kenya with fellow cast members Brooke Vincent (Sophie Webster), Ryan Thomas (Jason Grimshaw) and Ben Price (Nick Tilsley).

The documentary was made to raise awareness of life threatening diseases such as HIV and AIDS, with the soap stars  visiting local tribes who are still struggling after last year’s famine.

Cleaver  began to feel ill after returning to the UK, and was rushed to hospital where she  underwent emergency testing to rule out the possibility that she had contracted malaria.

She was sent home to recover, despite still feeling unwell, after doctors determined that she had not contracted the disease, but it remains unknown at this time if and when she will be able to return to the soap.

“No-one really knows what’s wrong with Sue, but she’s been feeling very ill,” a source told The Mirror newspaper.

“It started pretty much as soon as she got back from Kenya.

“Obviously serious alarm bells start ringing when you come back from Africa feeling unwell ­because you hear so many horror stories about people contracting ­diseases out there.”

The source added: “Sue spent a lot of time with children in ­orphanages. She ate food cooked in the traditional way, often out in the bush. It means there were a great many times when she could have picked up a bug.”

luckily the paper reports that there was little disruption to last weeks filming as Cleaver had not been due to appear in many scenes, but it could become a bigger issue if she takes much more time off.

“It may become a ­problem if she’s off too much longer,” the insider added. “Having said that, all the bosses are concerned about is her recovery.”

Corrie Goes To Kenya is due to air later this month.
