On the other hand, the acceleration of the melting of the glaciers feeding the lake has also increased the quantity of sediments which are transported there. “This will put hosts and viruses in contact that would not normally have been,” explained Audrée Lemieux. Nevertheless, the authors of the study were careful to specify that they do not foresee a viral overflow or a pandemic. "The probability of dramatic events remains very low", according to Audrée Lemieux. But according to the researchers, the risk could increase with continued global warming, as new hosts could venture into previously inhospitable regions. The possibility of an overflow is "completely unpredictable, and its consequences too, ranging from a benign character to a real pandemic", she added. This is the first time such a study has been conducted in an environment like the Arctic.
