Her immune system, statistically; has got to be pretty well trashed. Add all the recent spate of public outings she's engaged in lately, Gracie being around & it's easy enough to believe she picked up something. At her size, high probability of crappy immune system & infrequent exposure to run of the mill germs to keep her immune system primed & she's an infectious disease statistic ready to happen. I'm a self-admitted autist on the topic of infectious diseases, pandemics & that sort of stuff & seasonal flu is 1 I follow closely. This year, all signs point to a wretched flu seasons. There have been significant genetic shifts in the circulating strains & the southern hemisphere had a hellacious flu season. Even a "modest" bout of genuine influenza would pin her to her bed from fever/weakness & she's a very high risk for all the nasty complications & secondary infections. She ends up with 1 of those & if she's lucky enough to survive, the chances of remaining bedbound after are pretty high. But so far, she's proven remarkably resilient so we'll have to see. And yeah, her lymphoedema(s) may be starting to infect - who knows with her? Enough nerdiness for this week...
