There are 15 COVlD hot spots across the US, according to our county-level map of CDC wastewater data. See Alt text for details. PMC Weekly COVlD Report: pmc19.com New Interactive Map: pmc19.com/interactive.php
Starting tomorrow, you will be able to scroll over each county for county-level prevalence estimates.

Had mammogram, Dexa scans at hospital today. Got excited when among patients and staff I spied ONE other person masked...'til I saw it was below her nose...oh well. Onwards. What I'd do without @michael-hoerger.bsky.social's data, encouragement, #CovidCautious community, I don't know. #stillmasking

@michael_hoerger: Quick update on today's CDC COVlD data. Good news: There's no steep national rise as would be typical by this time of year. Most of the larger outbreaks have gotten smaller. Bad news...

It’s Wastewater Wednesday! How are COVID levels? We’re using two sources to help us keep track of the country and our state of Oregon. Thank you to @michael-hoerger.bsky.social for the map and graph, and OHA for continuing to track data coming from our wastewater treatment centers!
California, Oregon, Washington, Alaska, and Hawai'i are experiencing ongoing COVlD outbreaks. Use layered protection, encourage local media to cover COVlD to protect communities, and urge public health programs to promote boosters and offer free N95s and tests.

This week, the US CDC launched a new webpage, stating the following: “ ‘Vɑccines do not cause autism’ is not an evidence-based claim. ”
Saving this to show to the next person I encounter who tries telling me "the pandemic is over" and I don't need to take precautions.

Guess what, folks? After a long, blessed spring/summer lull, COVID-19 is picking up again in Indianapolis (and elsewhere), just in time for #GenCon. The ventilation at ICCLOS is NOT adequate to handle Gen Con's crowds. Do yourself and others a favor: use azelastine and MASK UP.

Friday's CDC data show a COVlD outbreak in the Bay Area. Median levels are "High" in Alameda County. The 6 wastewater monitoring sites read Very High, Very High, High, High, Low, and Very Low. #MaskUp PMC: pmc19.com CDC data (click CA from the dropdown menu): www.cdc.gov/wastewater/r...
Mask up, Bay Area friends.

The US has 10 COVlD hot spots (June 29, 2026) 🔹1 in 264 people actively infectious 🔹Levels flat or slightly rising, with volatility in CDC and Biobot reporting 🔹Ongoing major hot spots in Texas & Guam 🔹Isolated spikes in California, OR, NV, AL, GA, WV, NJ, and NY
CDC Update 🦠 New Orleans - Very High levels of RSV, which is particularly dangerous for young children & older adults. The entire state is shown as Very High, but the 2 monitoring sites are in NOLA. In fact, one is Very Very High (likely West Bank) & the other Very Low.

Central and SE #Texas have been on fire w/COVID for 21 days. Levels are extremely high in College Station, followed by near Houston, then Waco. The CDC defines Texas as "very low" because 52% of wastewater sites are very low. That misses the public health opportunity.
US COVlD Update (PMC) ◾️1 in 310 Americans estimated actively infectious ◾️9 hot spots (see Alt text) ◾️Large, lingering outbreaks in Central/SE Texas & Guam ◾️Levels are stable or slowly rising 1/3
COVID Alert❗️Biobot released their 1st COVlD report in a month, and it shows levels rising in the US after the prolonged national relative "lull" in transmission. biobot.io/risk-reports...
In 2026, the biggest COVlD concerns are #LongCOVID and excess deaths. However, with the massive outbreak in Central and SE Texas the past few weeks, COVlD emergency department (ED) visits have escalated in the region, likely underestimates due to diminished testing and reporting the past 2 yrs.
PMC Update, June 8, 2026 The CDC reports COVlD levels are "Very Low" across the US. PMC estimates 1 in 300 Americans actively infectious. BUT there's an outbreak in Central/East Texas. We estimate ≈1 in 30 residents in key counties are infectious. Video 👇 THREAD 1/3 🧵
