Two new studies provide evidence that a common viral infection might trigger type 1 diabetes.
Previous studies had suggested that infection with an enterovirus such as cocksackie B enterovirus might play a role in type 1 diabetes. In one of the new studies, scientists from England and Scotland found evidence suggesting that type 1 diabetes might be triggered by an enterovirus infection in genetically susceptible children (Richardson SJ et al. Diabetologia. doi: 10.1007/s00125-009-1276-0 [published online March 6, 2009]).
