It ain't the flu, folks: flu test positivity is currently at 0.87% but COVID test positivity is currently at 13.4%. If you have symptoms of a respiratory infection, kindly test yourself for COVID and wear a mask at least until the symptoms resolve. Please and thank you.

@DataDrivenMD is it true that there’s a variant circulating that doesn’t give you a fever or any of the other outward symptoms?

@Rfm @DataDrivenMD yes (but alter to “doesn’t *necessarily*”). Or it gives you a fever low enough to be mistaken for heat sickness—a major problem this year. We had a variant in Japan a few months ago that mainly presented with pinkeye.

@roque @DataDrivenMD It's terrifying to think that the most successful variants are going to be the ones that are the least detectable.

@Rfm @DataDrivenMD That's all of them.

They all have a certain proportion of asymptomatic infection that makes anyone a potential infection vector. Hence the importance of pervasive masking.
