Antiviral medication may be effective, but some strains of influenza can show resistance to the standard antiviral drugs and there is concern about the quality of the research.

In 2013, a study on the genome of several sensitive, ultraresistant, and multiresistant M. tuberculosis strains was made to study antibiotic resistance mechanisms.

The rest turns into a stable compound, which survives filtration into the water systems, thereby exposing the very aquatic birds that would carry flu and providing them a chance to breed resistant strains.

Finally, they will be robust democracies.

The vaccine is reformulated each season for a few specific flu strains but does not include all the strains active in the world during that season.

However, since the strains produced by drift will still be reasonably similar to the older strains, some people will still be immune to them.

This is called antigenic drift, which slowly creates an increasing variety of strains until one evolves that can infect people who are immune to the pre existing strains.
