How much should we be concerned about all this?
One argument is that the risk from permafrost pathogens is inherently unknowable, so they should not overtly concern us. Instead, we should focus on more established threats from climate change. For instance, as Earth warms northern countries will become more susceptible to outbreaks of "southern" diseases like malaria, cholera and dengue fever, as these pathogens thrive at warmer temperatures.
The alternative perspective is that we should not ignore risks just because we cannot quantify them.
"Following our work and that of others, there is now a non-zero probability that pathogenic microbes could be revived, and infect us," says Claverie. "How likely that is is not known, but it's a possibility. It could be bacteria that are curable with antibiotics, or resistant bacteria, or a virus. If the pathogen hasn't been in contact with humans for a long time, then our immune system would not be prepared. So yes, that could be dangerous."

We have been warming since 1700 coming out of the little ice age.
This is not the first time bacteria and viruses have survived frozen by a cold spell to come back and infect us.
Climate change has been happening since the Earth formed and will continue until the Earth is no more, man cannot bottle climate change all he can hope is to adapt to it.
