I was watching a television show yesterday and the premise of the episode was that a terrorist group had broken into an old abandoned USPHS lab and stole samples of the original strain to use as a biological weapon. It got me thinking, is that particular version of the flu virus still particularly dangerous? I know H1N1 strains are still dangerous and have been responsible for a few more pandemics since the Spanish flu but it seems that we should have some resistance to the strain that caused that pandemic. My reasoning is that it never went away. We didn’t beat the Spanish flu with vaccines and health measures rather it just killed pretty much everyone it could and we eventually developed a level of resistance to it that made its threat more in line with the seasonal flu. If my reasoning is correct then the terrorists releasing the virus in the subway shouldn’t be any more dangerous that someone with the flu taking the subway to work which is a common occurrence during flu season.

So, how does it actually work? Did we develop a resistance like I think or would a release of the original strain start a new pandemic?

    The original Spanish Flu would absolutely fuck us up.

    The reason it became mild has nothing to do with us building immunity but because a virus killing its host is bad for business (or strictly speaking, reproduction). A lack of viable hosts puts pressure on the virus’s gene pool and in the end, the variant that is most successful at spreading and reproducing will win out.

    That means not killing your host and only doing mild, repairable damage to other potential hosts so that humans don’t take an infection so seriously.

    We saw this exact pattern with COVID, with successive iterations being less deadly than the last.

    My understanding is that it’s still with us, but it’s evolved over time to be much less deadly, and that that’s the biggest reason it’s not much of a problem for us. We probably have some more immunity to the original strain because of our exposure to the evolved version, so I doubt the original would be as much of a problem as it was in 1918 (and because medicine has drastically improved), but it might not be a walk in the park.

    Seems like a shitty weapon of you can’t control it and it’s going to end up impacting your own people as much as anyone else, but maybe the terrorists in the show didn’t care.

    I don’t know, but last month three people in my family, including one who is on immuno blockers, caught swine flu from 2009 (verified by PCR) and did have cold-like symptoms, but no hospitalization or other complications and no longer than a week. We got it tested because one sick person is non verbal and has a history of pneumonia, so whenever she gets a bad cough I take her to have someone listen to her lungs and this time they opted to test for the strain. I kind of wish we could do that more often as it’s very interesting to know and see these things come around. They all had this year’s flu vaccine, which every year includes some h1n1 variant, as had everyone else in the house who didn’t get sick at all. So anecdotally and unscientifically, I would say Spanish flu is not a threat, especially if you’ve been getting flu vaccines every year.

      Immuno blockers suck. My mom has an autoimmune disorder and has been on them for decades to control it. They’re better than not being able to control her disorder of course but every minor bug that goes around is a serious issue for her. Glad this round went well for your family.

    There are many factors at play.

    Survivability is much higher. A lot of the deaths are attributable to secondary opportunistic infections that are now treatable with antibiotics, which did not exist at the time. We now have a plethora of treatments that did not exist at the time, for example many people were saved from death by covid by giving extra oxygen for just a few days. That would have helped h1n1 victims too.

    I don’t know how much of a threat the original strain is at this point, but if anything I would be concerned about H5N1, what’s usually known as avian flu. The only thing currently holding it back from being a pandemic is that it’s not efficient at infecting humans yet. But it is extremely deadly, killing 50-60% of those who get infected.

      And as more of a hot take, people need to reckon with the zoonotic origins of so many of these diseases. If it weren’t for humankind’s addictions to consuming animal flesh and their secretions - and the animal agriculture, loss of habitat for wildlife, and all the conditions these things create for the incubation of deadly diseases - we might never have had a covid pandemic. Likewise, an h5n1 pandemic may be a matter of when, not if, because the vast majority of people still refuse to let go of their gluttony for consuming animals.

      If you think of all the hate there is for antivaccers, and the harms they caused in 2020 - and deservedly so - omnivores deserve every bit as much, if not more, for the roles they play in the outbreaks of these diseases.

          I’m not saying I agree with them, but I’ve heard the argument they’re trying to make before.

          It’s not about eating the meat, it’s about the supply chain that results in meat on your table. That supply chain puts humans in close contact with large numbers of animals.

          COVID supposedly came from a market where close contact was extremely common … basically street vendors selling a variety of animals (primarily for cooking).

            If there wasn’t people going into a cave for food, there’d be people in there for another reason. Bats don’t give a huge amount of shits why you disturb them or even if it was by accident.

              That ignores the issue of frequency. The chance of someone crashing their car (lifetime) is much higher than their chance that day will be tonight.

                Here’s the thing though, COVID can linger for a long ass time, especially in a population. And it only needs one unwary cave explorer to disturb the bats and get bitten.

        …we might never have had a covid pandemic.

        That is patent nonsense. Consumption is not the only way such diseases get spread. It is not even the most common. It is far more likely that patient zero was bitten by an infected bat than trying to eat it.

        Sorry you’re getting downvoted. I don’t know if I agree with you, but back in the golden ages of Reddit the rule was don’t downvote because you disagree, downvote because it’s a shit comment. I don’t think your comment was shit… I think we’ve brought way too much of modern reddit to lemmy.

          It’s why I put it in a separate comment. It’s been scientifically shown that people often feel threatened and angry at the mere presence of vegans. What it comes down to is that most people want to believe that they’re at least mostly pretty good, but veganism challenges those narratives and highlights that the vast majority of people are very much doing things every day that are very wrong, and that they’re not living by their own standards.

          I’ve only been vegan for two years, and have been learning very quickly that I need thick skin for it, and that it means every statement I make on the topic will get scrutinized by the highest standards of skepticism while every carnist can just chime in with all the same tired lies about veganism that have already been thoroughly debunked for years now.

    Most of us have never encountered it and would not have resistance. In the 1977 H1N1 outbreak many older people did have resistance (due to a flu in the 40s), younger people did not. That wasn’t Spanish flu itself though.

    The Spanish flu strain was particularly devastating to people with strong immune systems, many young and healthy people who would have typically developed a resistance did not recover.
