Hospital doctors who are dealing with a superbug outbreak have confirmed they are treating another suspected case.
Two wards at Lincoln County Hospital are currently closed because of two separate infections.
One is the superbug clostridium difficile and managers say the other is a more common winter sickness virus. In total four wards are affected.
Officials have not confirmed how many patients are involved but said around 10 were being treated for clostridium.
Director of nursing Sue Glaister said: "The clostridium is affecting predominantly the elderly who have serious underlying disease. They have had a course of broad spectrum antibiotics so that makes them susceptible to infection.
"We're taking all necessary measures to contain the outbreak and to eliminate the infection by making sure antibiotics are used judiciously and by isolating the relevant patients."
