These are mutated bacteria that are resistant to antibiotics and are liable to cause serious problems. Also no-one will be immune from the mutated bacteria
Virus mutation
They tend to mutate more often than bacteria. This makes them hard to treat and hard to make vaccines against as they could easily change
