Influenza, particularly tertiary effects like pneumonia, has been a public health concern in Japan, especially among the elderly. The country typically experiences a spike in flu cases during winter. The inclusion of atypical symptoms, like abdominal pain and diarrhea, has raised alarm, prompting authorities to focus on public health awareness campaigns and vaccination drives.

In comparison, the US and EU have also seen spikes in flu cases, but they rarely appear in headlines unless it's a severe outbreak or pandemic. Flu injections are actively encouraged and sometimes mandatory in certain demographics. The approach to public health in these regions generally involves widespread flu vaccination more so than Japan, where personal hygiene is also heavily emphasized.
