US COVlD Update, PMC, July 27, 2026 ▪️10 hot spots (see Alt text) ▪️Persistent high/very high levels in TX ▪️FL, AK, HI, & the continental northwest picking up ▪️1 in 198 people estimated actively infectious nationally ▪️1.57 million estimated weekly infections & rising (1/2)

The US has 10 hot spots. There are major outbreaks across much of Texas (high/very high). Houston, denoted by the light blue county in the southeast (Harris) has 1-3-week reporting lags at most sites so may be worse than noted. Hardin county, two counties over to the east/northeast, continues to experience BA.1 Omicron-level transmission. The Texas surge is bleeding into estimates for western Louisiana. 
There are 9 other outbreaks: southeast Alaska (Juneau, high), Hawai’i (Honolulu and Kauai, high), north central Oregon through the Washington coast (high), western Nevada (Carson City, high), the Utah-Idaho border region (very high), southwestern Colorado (high/very high), southern Florida (high/v high), Atlantic City, New Jersey (high), and Grafton County, New Hampshire (high). The outbreaks in the Bay Area and Guam declined since last week. Note that the CDC state-level map shows no state median in the high/very high range, which is atypical. Higher levels tend to be more widespread.

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.

As of July 20, the US has 10 COVlD outbreaks. ✴️1 in 243 Americans estimated actively infectious ✴️200,000 estimated new daily infections ✴️Enduring outbreaks persist in Texas + Guam ✴️Outbreaks in the Bay Area (CA), NV, ID, CO, KS, KY, SC, HI Details in Alt text. pmc19.com

The US has 10 hot spots. There are major outbreaks across much of Texas (high/very high). Houston, denoted by the light blue county in the southeast (Harris) has 1-2 week reporting lags so may be worse than noted. Hardin county, two counties over to the east/northeast, has BA.1 Omicron-level transmission. The Texas surge is bleeding into estimates for western Louisiana. 

The Guam surge persists, and there are 7 other outbreaks: the Bay Area of California (Alameda, high); northeastern Nevada (Washoe, high); southeast Idaho (Bannock, very high); northern/western Colorado (Mesa to Routt, high/very high); central Kansas (Reno, high); north central Kentucky (Jefferson to Fayette, high/very high); southern South Carolina (Jasper, high), and Hawai'i (Kauai, very high). The Kauai outbreak is similar to BA.1 Omicron-level transmission.

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

PMC county-level national heat map from CDC data.

There are major outbreaks in central/southeast Texas (Very High) and Guam (Very High). Other spikes include south central Oregon (Klamath; High), specific counties in California (San Benito, Fresno, Napa; High to Very High), northeast Nevada (Very High), southeast Alabama (High), Newton County in Georgia (High), western West Virginia (High to Very High), Hunterdon County in New Jersey (High), and Chenango County in New York (Very High).

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.

RSV map, LA as Very High

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.

Screenshot from Twitter. CyFi's current and recent posts emphasize the ED visit increases in two large TX cities in the region.

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 🧵
