On page 390 of the article "Lecture Link: The emergence of a 'new' parvovirus" in the September 2012 issue, the second sentence in the last paragraph should have read: "So even if its test results are negative, a patient strongly suspected of having parvovirus infection (based on signalment and clinical signs) could still have the infection and should be treated appropriately."
We regret any confusion this error may have caused.
