US summer surge of #COVID19—hopefully modest—is starting. Biobot & NWSS report small increases in the past week (particularly in the West & possibly South) driven by a new wave of immune-evasive variants. Nationally, COVID in wastewater is near our 12-month low point last summer. Outdoor activities may help limit this surge. A room with 25 people has an 18% chance of including someone infectious.
