I keep hearing or reading people saying that this is less deadly than the flu. Where is that coming from? I'd heard it was 2% death rate with CV. But today I read that the death rate in Wuhan was actually closer to 4% which is where the majority of cases are. But I'd also heard flu was .10%
My biggest concern is that I've heard that the percentage of people needing "intensive" care is around 25%. Then today I heard the WHO talk on this and they said 15% are in severe shape and 3% critical.
Does anyone have any idea how that compares to the flu? I'm skeptical about our flu stats and how they come up with them since hearing they don't actually count each adult with the flu but basically lump all respiratory illness together as a flu death if the patient dies. But I sure as heck have never seen 18-25% of the people I know need hospitalization for the flu let alone breathing assistance and I believe they also specified ECMO in that talk. That is a crazy high percentage of people being seriously or critically ill.
Also, if it's really no worse than the flu then why are they requiring masses more medical care/hospitals/quarantine camps? I'm sure China deals with the flu in the winter as well.
I'm just not buying the, "It's no different than the flu. But we need to prevent anyone from China coming over here and quarantine every citizen who does manage to come back here." If this many people were actually getting this sick and dying at this rate from the flu then why the heck aren't we closing down borders every winter? The messages are just so mixed. "It's fine. Don't panic. Let the government panic for you."
It's very hard to have a firm idea of the mortality rate at the moment. Hubei, having greater numbers of confirmed infected would, in the normal way, be the best source for numbers. But, it's strongly believed that ever since we became aware of the new coronavirus in Hubei that the confirmed cases was the tip of the iceberg, with the majority of cases thinking they had the flu, or not being sick enough to go for testing. Then some hospitals there seem to have got so overwhelmed with really sick patients that they couldn't test everyone who wanted to be tested.
There's a lag that needs to be taken into account when considering the mortality rate. The date of confirmation is likely to be X days before death occurs. So on the day that person got infected, there were fewer cases than there are on the day of their death. So you'd ideally need the final figures from an outbreak that's ended, so that you can do deaths/total cases, or you'd need to average out the time from infection to death and go back to the total infections on that day and do today's total deaths over that number.
The total cases outside China should give better estimates while there's still few people outside of known contacts coming down with it. But there aren't really enough cases outside China to estimate the mortality rate, especially if you have to go back five or ten or fifteen days to get to the average date when the person dying today was actually infected.
Hospitals normally try to match bed numbers/doctor/nurse numbers to the average number of patients per year. Add an unexpected 10,000 patients a month to a single city, and the resources aren't in place.
China is hoping to reopen Hubei from quarantine asap, but they're as aware as we are that there are a lot of infected people there who haven't been counted in official confirmed case figures. Not only do they need to open the quarantine of the province, they also need people to be able to get back to work, school, etc. People need to work to pay the bills, the factories need to be making products for sale at home and abroad. But at the same time they don't want the virus to spread. The number of cases they currently have has caused a number of nations to stop flights to/from China.... If they were to just reopen Hubei for business and remove the quarantine then they'd start seeing far more cases in other cities and provinces in China, and how are the flight bans going to get removed if that happens? Plus, then more cities might end up with more cases than their hospitals can cope with. There's a shortage of masks, gloves, etc.
So the Chinese way is to take the hard line, knock on doors and forcibly take people into quarantine centers. We might not agree with it or like it, but I believe they're trying to do it for the public good, to try and prevent more people getting infected and reduce the R0 rate.
