Epidemiologic data locally shows a twin peak followed by a decline in the incidence of new cases. As things rapidly got worse in August, the population self moderated, and this led to an initial decline from the first peak, about 2 weeks later.
M <-- the valley in the M.
This was undone, paradoxically by the announcement of restrictions.
The day before the mandates became effective, hordes of idiots rushed out to riversides, bars, beaches, etc. 2 weeks later, we got the second peak. This has been termed a "las lap" spike, after the tradition of binge drinking, violence and sex that happens in the last 3 hours of Carnival, every year.
By the same people? Maybe.
Decreased risk assessment and bad impulse control are closely linked:
Drugs commonly prescribed to treat Parkinson's disease are linked to impulse control disorders such as pathological gambling, compulsive buying, hypersexuality and binge eating in some patients, warn researchers.

Increased dopaminergic transmission in the brain is connected to the phenomenon. In Parkinson's, this is decreased in motor control areas, the basal ganglia. The medicines increase dopamine globally, back to normal there, but higher than normal elsewhere, causing reduced prefrontal cortex function. So poor impulse control, and poor risk assessment result. Other side effects include a kind of psychosis, with hallucinations and disordered thinking.
It's possible to pharmacologically do the opposite.
Antidopaminergic drugs are used in Psych. To treat psychosis. They blunt impulsive actions, and suppress delusional belief formation. Such as New World Order being a believable threat, but the actual pandemic not being real. As you might infer, the side effects are movement disorders, like in Parkinson's.
I'm not proposing or suggesting any people be medicated. These are just observations on brains, and our behaviours. We need better, more specific, medicines obviously. Evolutionarily, the people with poor impulse control, disordered thinking etc, are more likely to reproduce. But pandemics help balance things out.
As hard as it is to concieve, pandemics might shift humanity towards greater sanity, every 100 years, by simply winnowing out the weakest.
