The Who have been forced to scrap their 25 remaining US tour concerts after it was revealed lead singer Roger Daltrey has viral meningitis. The band were due to start the second part of The Who Hits 50! North American tour, due to start in San Diego on 21 September. Gigs in Anaheim, Las Vegas and Los Angeles have also been cancelled.

Doctors have ordered Daltrey, 71, to rest. On the band's website a statement said Daltrey was particularly disappointed as he had been especially looking forward to the Teen Cancer America benefit in Los Angeles – a charity that he and The Who have worked for.

Daltrey said: "We are very sorry to disappoint our fans in this way. For the last four weeks, I have been in and out of the hospital and have been diagnosed with viral meningitis. I am now on the mend and feeling a lot better, but I am going to need a considerable time to recover. The doctors tell me I will make a complete recovery, but that I should not do any touring this year."

Meningitis is an inflammation of the linings around the brain and spinal cord. Most cases are believed to be caused by viruses. Some of the symptoms of viral meningitis include headaches, aversion to bright lights, neck stiffness, fever, nausea and vomiting. Sufferers normally recover without medical treatment

The Who's lead guitarist Pete Townshend said they hoped to reschedule their cancelled shows to next year. He said: "We are rescheduling all the shows for next Spring 2016. We apologise to all our fans who have supported us in the last 50 years. Once Roger is completely well we will come back stronger than ever and Roger and I will give you all a show to remember." Earlier this year the band played at the UK's Glastonbury Festival, receiving good reviews for their performance.
