Coronation Street actress Sue Cleaver has been treated in hospital for a mystery illness she contracted while filming in Kenya.

The 47-year-old, who plays Eileen Grimshaw in the soap, spent a day and a half in hospital while doctors carried out tests, amid fears she had caught the potentially fatal disease malaria.

However that was ruled out, and she is now recovering at home – although it remains unclear when she will be well enough to return to Corrie.

“No-one really knows what’s wrong with Sue, but she’s been feeling very ill,” a source told the Mirror. “It started pretty much as soon as she got back from Kenya.

“Obviously 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.”

Sue had been in Kenya with co-stars Brooke Vincent (Sophie Webster), Ryan Thomas ­(Jason ­Grimshaw) and Ben Price (Nick Tilsley) to film a documentary called Corrie Goes To Kenya.

The film, which will be shown later this month, saw the stars visiting local tribes who were still suffering after last year’s famine.
