dreamsharkI admit it, my first reaction was along the same lines as everybody else I know. Oh, it's that SARS thing again. Wait, whatever happened to SARS anyway? It just kind of disappeared after a while, right? Never did spread much beyond China. Too bad about the deaths in China, but *shrug* not something I need to worry about. And, hey, a 2% fatality rate isn't really that high, right?
But I can't help following medical news obsessively, and I'm beginning to realize that this is much worse than SARS. The fatality rate is lower (SARS was an alarming 5-10%) but it is FAR more contagious. It's following a pattern much more reminiscent of the 1918 Spanish Flu (which had a mortality rate of only 2-5% but spread like wildfire and killed more people worldwide than World War I).
Usually, when a new disease is identified the initial fatality rate estimate is way too high because it's based solely on people who were sick enough to seek medical care. Once we get better at identifying cases, the mortality rate usually starts dropping. For the first few weeks the rate held steady at 2% even as the total number of cases exploded, but I really expected it to head down to about 1%. But no. Now the rate is inching UP instead of down. The most recent numbers I've seen were about 75,000 cases confirmed (worldwide) with about 2,000 deaths. Do the math. The reported fatality rate is RISING, even as more sub-clinical cases are identified. That is Not Good.
Worst of all, there is growing evidence that people who are completely asymptomatic can spread the virus. That's not 100% clear, but there doesn't seem to be any doubt that people with symptoms no more concerning than a common cold can spread the disease. And the initial guess of a 2-week incubation period seems to be about right (and that's a long incubation period). The epidemiologists' nightmare is a highly contagious disease with a long incubation period that is contagious during the incubation period. That might be what we have here.
Remember those 400 Americans who were evacuated from the Diamond Princess plague ship? The ones that were sick were sent to hospitals in Japan, so supposedly the only evacuees being repatriated were healthy. But it turns out that 14 of those 400 actually had the virus (but no symptoms). They had all been tested, of course, but the results didn't come back until they were loading them into the planes. So they sealed off these potential carriers with plastic in the rear of the planes, hoping that would keep them from infecting any of the healthy people in the front. Did that work? I don't know. I think all those unfortunate folks are still in quarantine, so it's too soon to be sure.
Latest news of the day - a surprise explosion of cases in northern Italy. Nobody seems to know the source of infection - a single individual? Health officials seem to think so, as they are reportedly desperately searching for Patient Zero. If one infected person in a public space can lead to 170 cases in 3 days, we're in trouble, folks.

If she doesn't want to visit him with a possible (though minuscule) chance of exposure, she doesn't want to do it to anyone else, either. She's bored but holding up well, and has watched a lot of television.

Date: 2020-02-24 06:14 pm (UTC)As far as new babies go, babies and children seem to be oddly unaffected by this particular virus. Not that I'd recommend exposing them, of course, but for babies, flu (or even a cold) is probably much more of a threat. I actually got a flu shot this year for the first time ever before visiting my new preemie grandsons. I didn't get flu, but then, I never do. Just being extra careful for the babies.
Almost everybody in the house DID get a cold, which made us all very nervous, as the babies had just come home from the hospital and still weighed under 6 pounds each. This was over Thanksgiving/Christmas, with a total of a total of 7 people (not counting babies) passing through the household. Our protocol was that whoever was in the first 3 days of their cold wasn't allowed to hold the babies, and everybody used hand wipes before touching them whether they thought they were sick or not. I put a big container of Lysol Antibacterial Wipes in the bathroom and every time I used the bathroom I wiped down the sink, counter, toilet handle, light switches and doorknobs.
The babies did not get the cold. Neither did Amber (who has Teacher Super-Immunity Powers). All the rest of us did, clearly passing it from one to another despite all these precautions. I'm not sure exactly what lesson to take from that, frankly.
