Running Its Course
Over the past week, I've heard an increasing number of anecdotes that all concern "virus shaming." That is, catastrophists who have been brain-washed by Team Apocalypse demonize those who have rejected the team's increasingly irrational narrative. The catastrophists have placed themselves in full "shelter-in-place" mode and are naturally unhappy about their isolation, lack of social contact, and marginalization from the rest of society. When confronted with people (and there are millions of such people) who are a bit calmer about the threat (or statistical lack thereof) of COVID-19, the catastrophists lash out, criticizing any decision to lead a more normal existence.They might accost a person in a grocery store who isn't wearing a mask. They might yell at another person who is standing too close to them at an ATM machine (without a mask!!!!!!!) They won't allow another person to enter an elevator with them, even if that other person is wearing a mask. They begin exhibiting the unhinged behavior of a hysteric.
Are these asymptomatic people contagious? And if so, for how long?Yes, they are probably contagious, but it's very hard to prove that they are driving the pandemic in a significant way. [link added] It appears that viral burden — a marker for how contagious a person is — usually correlates with severity of symptoms, so those with no symptoms have less virus to spread. And certainly the “superspreading” events that have been studied have a symptomatic or pre-symptomatic person as the initial source.How long asymptomatic people are contagious is even less clear. We know from studies of people with symptoms that transmission has not been reported more than eight days after symptom onset. It is implausible that people who are asymptomatic — with their lower viral burden — would be contagious for longer than this, and it’s probably shorter.
