WastewaterSCAN monitors infectious diseases through municipal #wastewater systems across the U.S. to inform public health responses locally and nationally.
2/ COVID-19: COVID-19: Nationwide, SARS-CoV-2 is in the “High” category with high concentrations and a no significant trend up or down over the last 3 weeks. 
2/ COVID-19 Variants: In sequencing data from a subset of WWSCAN sites, we see that the KP family makes up ~66% of variants. KP.1 (lime green) is at 3.8%, KP.2 (slate blue) is at 8.9% and KP.3 (light blue) is at 53.3%. Sequencing data has a lag of 1-2 weeks after collection. 
2/ COVID-19 Variants: In sequencing data from a subset of WWSCAN sites, we see that KP variants are making up > 50% of variants with KP.1 (lime green) at 7.0%, KP.2 (slate blue) at 30.2% & KP.3 (light blue) at 39.8%. Sequencing data has a longer lag of 1-2 weeks after collection. 
2/ Influenza: Nationally and in every region, Flu A and B continue to be in the “Low” category and not in onset. 
For flu & RSV, wastewater offers a rapid population view of infections. So it includes healthy adults with RSV who don’t feel sick but can spread virus to those more vulnerable. Clinical data faces lag time, usually includes those most severely ill. cnn.com/2022/10/27/hea…
