BC19.Live - Butte County COVID-19 Tracker

🟣 Thursday, September 24, 2026 #COVID report for Butte County, CA First report since Sept. 5th. We've had some rises in the numbers since then in both Chico and Oroville, but then recent drops. It's too soon for me to say what this means, but I wanted to report where we're at.

💉 Vaccines Vaccines are available pretty much everywhere. Most places are allowing walk-in appointments. Check your local pharmacies for options. I'll keep an eye on the trends and let you know what I see. — Christian

Masks help spread the slow of COVID-19, and every medical study has verified this. Don't fall for misinformation online. It's important to use NIOSH-certified N95 masks or KN-95 masks. Cloth masks won't do much to slow the spread.

Social distance if you're immunocompromised or otherwise at risk of complications from COVID. Or if you just don't want to get sick.

Whether this means things are on the decline, or it's temporary, I cannot say. We just got the September 14-16 data within the past couple days, so we'll need to ee if this trend downward continues.

😷 Precautions Remember: A downward trend does NOT mean COVID is no longer present. And it's still at least in the 🔴 High territory, so you still want to be cautious.

🗓️ September 8-9: Chico was still at about the same levels. Oroville saw substantial growth (just one measurement, but it continues the sort of direction of growth we've been seeing).

Then a change: 🗓️ September 14-16: Chico saw much lower numbers than it had the previous weeks. Still in 🟣 Very High, but barely. Oroville dropped far down into 🔴 High.

Here's a timeline this month: 🗓️ September 1-3: We saw continued growth in both Chico and Oroville. Chico had a large spike in the data (which may not mean anything — this happens sometimes)

This changes the data I have. Some of the recent 🟣 Very High spikes are now 🔴 High. Some recent 🟡 Moderate levels are now 🔴 High. So some levels went up, some went down. With that said, we're still firmly in 🟣 Very High territory.

I report based on the wastewater data in Butte County. This gives us a way of seeing if there's an increase or decrease in the spread of COVID. It tells us "are people sick with COVID more now than before" at different times.

My dashboard calculated this using an older CDC method, which compared up to roughly 1 year in the past. The CDC has since updated this to better compare across up to 2 years, which gives us a better idea of what's normal at different times of the year.

💉 Vaccines The latest rounds of vaccines have been approved and some should be here very shortly. These should be a good match for the virus circulating. In California, these should be covered by your insurance and available at pharmacies as normal.

If you switch the selector at the bottom to 3 years, you can see how this compares to past surges. Notice that the data shows spikes, drops, and then spikes again. Wastewater is measured at different times from different sources, and what we're seeing is that they're all spiking into Very High.

The last two years, these lasted between 1-2 months, once we got into Very High territory. There's no way to know if we should expect 1-2 months this time, but it's worth planning for that.

COVID travels through the air when people cough or breathe out and can float in the air for up to 3 hours, so by limiting your exposure in indoor settings, you can lower your risk of infection. I'll keep reporting as the data comes in. Stay safe, stay healthy, and stay informed. — Christian

Oroville has shown elevated rates (🟡 Moderate territory) in the most recent sample. I would expect we'll see Oroville approach Chico's levels soon, based on past history.

😷 Precautions Now is the time to get serious about precautions, especially if you're at increased risk due to other health complications. Avoid large crowds when you can, wear a mask around others, and ensure fresh air is circulating in buildings.

Chico's surging. I mentioned last week that the pattern was resembling the start of previous surges. It looks like a surge is well on its way now, with multiple samples showing 🟣 Very High levels of concentration in the wastewater.

If you're at risk of health complications, and haven't had a booster in a while, it would be a good idea to talk to your doctor about options. Masking up and avoiding crowded indoor gatherings during a surge has also been a proven way to reduce your chances of catching the virus.

Fortunately, none of the current strains appear to be any more severe than what we've seen in the past year, though complications from COVID are still a concern for many.

There's not nearly as much useful information on which strains are present locally as there once was, so it's getting harder to gauge this.

😷 Precautions Based on past years, what we're now seeing in the data for Butte County, and what's going on throughout California, we should prepare for a surge.

💉 Vaccines On last week's discussion on the Facebook report, there were questions about when we'll see new vaccines targeting the current strains. It looks like this is in the works, and targeting Fall sometime.

This should cover one of the strains that appears to be going around right now (XFG.1). I haven't been able to find information about whether it'll cover the other strain that's growing (BA 3.2).

If I zoom out and look at the graph, we can see an upward trend for the past month. We saw the same behavior last Summer, preceding a surge into Very High territory. That doesn't mean we will this time, but it's a possibility. We do know it's at much higher levels than it's been all year.

Oroville's latest measurement (July 29th) has it on the border of 🟢 Low and 🟡 Moderate. It's expected that we'd start to see an increase there.
