In the original article "Cowpox Virus Infection in Pet Rat Owners—Not Always Immediately Recognized" by Becker et al. (Dtsch Arztebl Int 2009; 106(19): 329-34) two sentences were incorrect:
In the chapter entitled "Case 2" on page 330, the last sentence of the first paragraph should read: "A bacteriological wound swab remained sterile."
In the last chapter ("Discussion"), the second sentence of the next-to-last paragraph on page 333 should read: "Investigations in the 3 pet shops that were implicated in the first 4 cases did not confirm with absolute certainty the presumed epidemiological association."
