Everything Old Is New Again In Epidemiology

Suddenly public health “rediscovers” environmental monitoring for tracking infectious respiratory pathogens.

From the Detroit News comes this bit of news charting Omicron's decline in Michigan.

The level of COVID-19 infection showing up in sanitary sewage tests is "dropping sharply" in Macomb County, officials say, a potential indicator that the spread of the virus there is beginning to slow.

Lab tests, conducted from samples taken from wastewater in the seven sewage districts covering Clinton Township, show that the level of COVID-19 spiked Dec. 28, when it was at the highest level since the team started tracking it. Samples from more recently, taken on Jan. 4, Jan. 9 and Jan. 11, show a decline.

Will syndromic surveillance also make a comeback?

The world wonders….
