That's almost certainly a translation error. The University of Tampere press release states that "these studies clearly show that members of the group B coxsackieviruses are associated with the risk of type 1 diabetes", and the offending sentence in the Yle article would be the same in Finnish irrespective of whether the virus found is the only one or not (e.g. "löytänyt viruksen" would be "discovered a/the virus"). Finnish grammar doesn't have the concept of definiteness, meaning that a translator working from a Finnish source text would in many cases have to guess the intended meaning or look it up elsewhere. For similar reasons, many Finns have problems figuring out whether to use a definite or indefinite article when writing in English.
