Why is flu a very infectious disease and why is the flu injection not effective and what treatment is not helpful?
Understand the Problem
The question is asking about the reasons behind the high infectiousness of the flu, the effectiveness of the flu vaccine, and the types of treatments that may not be helpful for the flu. It seeks to understand the nature of the flu virus, how it spreads, and evaluate current treatment options.
Answer
The flu spreads easily due to rapid virus mutations and respiratory droplets. Vaccines may be ineffective due to mismatched strains. Antibiotics aren't helpful as flu is a viral infection.
The flu is highly infectious due to the rapid mutation of influenza viruses, which can easily spread through respiratory droplets. The flu vaccine may not always be effective because the viruses mutate quickly, and the vaccine might not match circulating strains. Antibiotics are not helpful for flu as it is a viral infection.

More Information
Flu viruses mutate quickly, allowing them to evade immunity. Vaccines need to predict future strains, which can result in mismatches. Despite this, vaccines still reduce severity and complications.
