red state – blue state – vaccinated state – unvaccinated state

The New York Times published an article demonstrating the partisan separation between US Democrats and Republicans by regression lines. As the one above, regressing the proportion of vaccinated on the proportion of Trump voters but no scale on the first axis. But no correction for age composition or population density. And the one below, plotted at the county level, which seems quite meaningless given the spread of red dots in Wyoming.

Still, there is a clear opposition between places (counties) that voted more than 70% Trump (representing 33M people) and those that voted more than 70% Biden (more than 58M people), even though county density, age composition, and earlier deaths from COVID should also be accounted for. But the vaccination rate also exhibits this opposition, with a 1.65 ratio between the first and last decile of the blue counties.

Influenza, anywhere?!

Everyone should take everyday preventive actions to stop the spread of germs, including frequent hand washing and people who are sick should stay home and avoid contact with others in order to limit further spread of the disease [CDC Public Guidance].

As I am getting ready to take my plane for the 3rd Rimini Bayesian workshop mentioned on that post (no, I haven’t yet changed my slides!), I am [rather idly] wondering why we do not hear more about the H1N1 pandemic. Checking on the site of the World Health Organisation (WHO) shows a widespread repartition of the flu since most countries are hit (I spotted Haiti and most of Africa missing from the list, but this may be due to a lack of proper reporting rather than no case so far).

Novel influenza A (H1N1) activity is now being detected through CDC’s routine influenza surveillance systems and reported weekly in FluView [CDC Surveillance].

While I see the point in not panicking people by adopting extreme measures like those taken in Mexico (too late) during the first weeks of the outbreak, it seems to me that nothing is done at the moment, at least as perceived through my everyday life. I do not see people wearing masks when they cough, washing hands more regularly and so on… It sounds like the [maximum] Phase 6 level announced by the WHO has no visible impact. Is it because the disease actually has less impact than previously thought? Mais que fait la police?!
