It's a bacteria. But this is apparently a very antibiotics-resistant strain. Nice.
Does this have the potential to become a global pandemic? Viruses are fragile things and can only target specific cells to reproduce, which makes them relatively difficult to spread... Like avian/swine flu.
In contrast, bacteria are tough and ruthless organisms. They can survive for a long time outside of a host organism, and can reproduce almost anywhere there is organic material.
Warmth accelerates their growth, and Europe is entering summertime.
