Far-UVC. What is it? How does it inactivate airborne pathogens? Will it give you sunburns? If not, why not? And if they work, why aren't they everywhere? In my latest explainer video I dive into all these questions and try to make some sense of it all. youtu.be/ujHMIdI2gLs

Did you know Long COVID can affect children? If your child has experienced new or ongoing symptoms after having COVID-19, talk to your doctor about the possibility of Long COVID. Learn more about Long COVID: www.cdc.gov/long-covid/a...

Clean air propaganda - PC Fan based air filters are quiet, powerful, energy efficient, and modular/repairable. A great choice for air filter nerds or anyone highly motivated for clean air. A little too fiddly for your average user though who might do better with a mass market product.

📣 I’m writing a story with The Sick Times focusing on why there are no clinical guidelines for treating children with #LongCOVID and how this affects families. If you're a family affected by Long COVID, feel free to get in touch - felicity.nelson@frogsandstars.com.

L.A. Material’s Tomo Chien found that L.A. issued nearly $1 million in invalid street sweeping tickets — many in one of the city’s poorest neighborhoods. LADOT claims it voided them but wouldn’t release the data to prove it. Check if your street sweeping ticket was invalid: buff.ly/zxkUcrI

Cleaning the air: 1 Box Fan & 1 MERV13 filter can make an air filter for $50 that actually works very well. Tape the filter to the back of the box fan and make sure the air flow arrow on the filter points towards the back of the box fan.

HPV infections are extremely common, but HPV vaccines can prevent over 90% of cancers caused by HPV. This Adolescent Immunization Action Week, talk to your child's doctor about protecting them from cancer by getting them vaccinated against HPV. Learn more: www.healthychildren.org/English/safe...

As you continue hearing about the new COVID-19 variant (the “cicada” variant) in the news, remember the protection remains the same! Wear the best mask available to you, keep indoor air clean, & stay up to date on vaccines to protect yourself & others from infection & serious illness from COVID-19!

Up to 60% of health care workers may have long COVID 4 years after infection

A strategy I am recommending to people who don’t want to mask all the time is always in healthcare facilities and public transportation, AND if you see someone in a mask, put yours on. The first helps protect spaces high risk people may have no choice but to go, the second shows them support.

A classic anti-masker tactic is to claim that if you don't wear a mask 100% of the time, it isn't worth it. Untrue. Every single time you wear a mask, you reduce the chances for viruses to spread. Wearing a mask always improves public health, even if you only do it occasionally.

It’s #LongCOVIDAwarenessWeek, but Long COVID will still be around once it’s over. Visit our website and follow along to learn how to recognize the signs: doh.wa.gov/long-covid

This week marked the anniversary of the start of the COVID-19 pandemic. We’ve summarized our thoughts a bit below, but tl;dr: Unfortunately, COVID-19 is still with us, & although we may be tired of hearing about it, it’s extremely important to continue to take steps to protect ourselves & others.

In other words, we’re know you’re tired of hearing about COVID-19. We’re tired of hearing about it too. But ignoring it does not help it to go away, so please continue to take protect your health.

Why do progressives and justice advocates seem to not care about COVID?

It’s still important to warn people about the dangers of COVID and make schools and workplaces safe, Andrew Wilkin says.

I'm a high school teacher who always has open windows and doors, 1 or 2 air purifiers running and I always mask. Your posts help me stay motivated to keep doing what's right! Thanks for what you do!

Bottom line from the last 6 years of COVID research : If you’ve got blood vessels, you’d be wise to avoid additional infections. Now is a great time to normalize wearing a respirator. Might feel awkward at first, but every person who does makes it easier for others to follow. Be a leader. 😷

Outside of this direct problem - it further prevents our ability to do 2x yearly updates to the Covid vaccines, which is strongly needed. One for the winter wave, one for the summer wave. You know, an appropriate utilization of the mRNA platform. Indirectly, this may even reduce flu vaccinations.

Personally not a fan of this combination Taco Bell and Pizza Hut model. Irrespective of efficacy - tying the variant selection of the flu with the Covid variant selection, to me seems like we will have an abysmally matched covid vaccine to circulating variants with a March selection for the winter

I'm almost 80 and I wear an N95 in public indoor spaces. I'm shunned by people regardless of their politics. I've sadly learned to trust no one (even people I know) to isolate when they're unwell. Covid is still here. Almost no one cares if they transmit disease and the elderly die.

I am a physician who will be wearing an N95 in all clinical encounters for the rest of my life because I don’t want to commit the harm of passing on a respiratory pathogen to a patient. This seems like a minimum duty, like handwashing, but I am unfortunately in a vanishingly small minority.

I’m going to say again, infecting your allies with a potentially debilitating and deadly illness is extremely foolish behavior in any kind of movement. You’re doing work for the other guys.
