Am noticing that people I know who've had #COVID are now fearless. They aren't really trying to avoid it anymore.

Some people think they are now #immune to further infection (for some unknown window of time) but could it also be something else?

I've seen people allude to the reduced feline avoidance behaviour in rodents with #toxoplasmosis

And also to a possible link between the #olfactoryNerve and a lack of input to the #insularCortex possibly affecting #behaviour

Anyone aware of any studies looking in to this at all? I'd love to read more. #covid

Sorry, I should have been more specific. Is anyone aware of any studies linking #COVID infection with reduced #avoidance of SARS-CoV2 in humans? #behaviour

Study is one of the few to show the behavioural effects of Toxoplasma gondii in wild animals.

Association of T. gondii infection with suicide: a systematic review and meta-analysis - BMC Public Health

Background Findings on the association between Toxoplasma gondii (T. gondii) infection and suicide are contradictory. This paper aimed to resolve this uncertainty by conducting a meta-analysis. Methods We found the relevant studies using keywords include “Toxoplasmosis” and “Suicide” and the related synonyms in international databases such as ISI, Medline, and Scopus. The eligible studies were included in the meta-analysis phase. The random effect approach was applied to combine the results. Results Out Of 150 initial studies, 15 were included in the meta-analysis. Odds of suicide in people with T. gondii infection was 43% (OR: 1.43, 95%CI; 1.15 to 1.78) higher than those without this infection. The test for publication bias was not statistically significant, which indicates the absence of likely publication bias. Conclusion This study confirms that T. gondii infection is a potential risk factor for suicide. To reduce cases of suicide attributable to T. gondii infection, it is recommended to implement some measures to prevent and control the transmission of the disease.

@TerriBlue416 yep, I've noticed that, too.

From what I have gathered from my friends, even some of the previously careful ones, it's not that they think they're immune, it's that "it wasn't that bad" (not true, all of them said it was the worst they've felt in YEARS) and "I just can't continue not living my life," which tracks with this theory.

I feel like I saw a recent journal article on this, but can't find it.

@TerriBlue416 Which is a completely wrong attitude - studies and data show that when you get COVID you become MORE susceptible to it again, and your immune system weakens, not strengthens...

I've had it twice, and it's N95s in public for me for the foreseeable future.

@jpthuot03 Oh I agree completely. I'm 100% on team masking. It's just something I've noticed among people I know.

@TerriBlue416 Yeah, I've noticed it too, to my immense frustration, and certainly wasn't taking *you* to task.

Although, I went to a concert last night (Bruce Cockburn!) and the guy beside me was wearing a mask. When I told him I was glad to see it, he replied that he put it on out of courtesy to the two of us, which I thought was very kind.
