Later today @rkfmiller will present a study on school masking for #COVID, showing that a 10% increase in kids wearing masks was associated with about a 50% decrease in the likelihood of detecting SARS-CoV-2 in wastewater from schools. #CROI2023 1/ Image
Interesting thing about this study is they sent people to observe actual mask use during school pickup (about 40% of kids wore them) rather than focusing on mask policies or requests to wear them. 2/
.@rkfmiller: "These were 7 year-olds wearing masks their moms bought at Target" & they still saw an effect. "It can be effective even with real-world masking strategies. It doesn’t have to be all-or-nothing -- even small amount helps." #CROI2023 3/

And now at #CROI2023, a special session on #monkeypox/#mpox.
John Brooks of @CDCgov: Mpox decline has not been even in all places -- we need to keep our eye on places where it hasn’t declined as much & need to stay vigilant for reemergence. Image
I'm not going to try to live-tweet this one & didn't request advance permission to share slides.
John Brooks (@CDCgov): Let’s get people vaccinated against #monkeypox/#mpox now, before spring & summer. Summer means Pride, Pride means a lot of fun, a lot of fun means a lot of sex. #CROI2023 Image

It's been a long day at #CROI2023, but I'll attempt to live-tweet @MichaelPelusoMD's presentation on #longCOVID. Though mainly an #HIV meeting, CROI also includes the hot infectious diseases of the day. (Thanks Dr Peluso for providing advance slides & permission to share.) 1/
@MichaelPelusoMD .@MichaelPelusoMD & colleagues' SCOPE cohort at @UCSF + international collaborators have now studied more than 700 people with #longCOVID 2/

.@MonicaGandhi9 presents promising results from @ZSFGCare @SF_DPH SPLASH program to treat disadvantaged safety-net population at Ward 86 with long-acting injectable antiretrovirals -- even if not virally suppression at outset. #CROI2023 1/
Among those without viral suppression (ie, outside FDA indication for Cabenuva), 55 out of 57 achieved undetectable VL after starting monthly injectables -- comparable to rates seen in pivotal clinical trials. 2/
.@MonicaGandhi9: We need innovations in #HIV treatment for this population. "If used creatively & used boldly, long-acting ART could really make a dent in the HIV epidemic." #CROI2023 3/

Susan Buchbinder (@SF_DPH @BridgeHIV) & Larry Corey (@fredhutch) discuss where we are with #HIV vaccines after Mosaico trial failure. Buchbinder says it's "a very vibrant time" in HIV vaccine research. Corey adds that the science is "terrifically fascinating." #CROI2023 1/
I think his characterization of sophisticated novel HIV vaccine approaches as "a little bit more complicated" & going to "take a little more time" is an underestimate. It's certainly a lot more complicated to explain versus traditional vaccines! 2/

But it's good to hear they're optimistic. I've been kind of discouraged about the #HIV vaccine research field since doing this @pozmagazine overview a couple years ago. #CROI2023 3/

.@profchloeorkin presents disturbing data on #monkeypox/#mpox among HIV+ people w/low CD4 counts. High rate of complications & death. Concludes mpox is an opportunistic pathogen & severe necrotizing form is an AIDS-defining condition, @CDCgov & @WHO should include. #CROI2023 1/
Concern about IRIS for people who start antiretrovirals once severe symptoms are underway -- can make worse. But unclear whether ART would be beneficial if started at beginning of mpox symptoms. 2/
The good news is no #HIV+ people with a CD4 count >200 died, nor did anyone who received #mpox vaccine. 3/

#DoxyPEP prevented STIs in gay men, but Jenell Stewart reports this was not the case for cisgender women. May be due to differing drug concentrations in vaginal/cervical vs rectal tissue or low adherence. We’ve seen something similar with TDF/FTC PrEP for women. #CROI2023
Here's my report for @eBARnews on the #doxyPEP study in gay & bi men & trans women presented last year.
ebar.com/story.php?3193…
Jennell Stewart (@drjenellstewart): "Stigma is a major issue regarding sexual health, STIs & HIV. It needs to be addressed if were going to make progress in this area." #DoxyPEP presenters at #CROI2023
