Fifth case of measles in Queensland sparks major health alert after infected person visited hospital ANOTHER case of measles has been diagnosed in Queensland, taking numbers in recent weeks to five. The man in his 30s had visited the Ipswich Hospital on three separate days in the past two weeks. Health staff are contacting people known to have been in close contact with him. The latest case follows the diagnosis of a 17-year-old Caboolture schoolgirl who had visited two Gold Coast theme parks and the Queensland Performing Arts Centre to see the musical Grease during the infectious phase of the illness. Queensland Health workers are trying to determine how the latest two cases caught the highly infectious virus. Public health physician Heidi Carroll said measles was one of the most infectious diseases and was spread through coughing and sneezing. ``Symptoms usually start around 10 days after infection but sometimes longer,"" she said. She said complications could be serious with about a third of young adults diagnosed requiring admission to hospital. The latest case visited Ipswich Hospital on August 26, 30 and September 1.
