I get what you’re saying. Potentially the 328 are all infected and helped spread this shit.
My information search was to say, every 24-25th person was positively infected. So you have a 1 in 25 chance of catching this if exposed. That’s shitty
Well here's the issue. So you had thousands of people on that ship. They were all confined to quarters for two weeks. 300+ of them became infected. When a person was identified as infected they were removed and sent to a hospital for quarantine.
America said we're going to fly a couple of cargo planes over and get our people. But only the ones who haven't tested positive. So you 328 come with us, you 44 have to stay.
On the way to the plane, they get a call that 14 tests came back positive. They ditch the plan of making infected people stay and decide to fly the 14 back.
Here's the problem. They removed 328 or so people from individual quarantine in their state rooms. And mixed them together, WITHOUT first definitely knowing that each of them was negative. So due to the lack of appropriate process, they exposed an additional 314 to the virus AFTER they spent two weeks in quarantine. Effectively blowing containment.
The question then becomes, how do they have a snowball's chance in hell of containing a community outbreak in the US, when they can't even maintain containment on a very controlled small scale group.
As for how contagious it is, the jury is still out due to shoddy numbers out of China. Most agree that it is at least as contagious as the common cold and flu. Just think of everyone you know that's been sick in the past two months and there ya have it, and that's with a massive flu vaccine program. Infectious diseases have a R0 scale they use. The number is the number of people who will likely be infected by a single infected person. If it's less than R1 that means ever person will infect less than 1 person. Meaning the illness will die out on it's own. An R1 means each person will infect one other person. Meaning the virus will remain stable. Anything above R1 means it has the potential to cause a pandemic as it will spread and grow. These numbers are ballpark because I'm not going to go look them up. The common cold is R2-3. Measles was like R18. Smallpox is R6-7. And Ebola was like R1.3. The new nCoV19 is suspected to be R2.5-3.5.
The trouble comes in when the R0 value is high and so is the mortality rate. The WHO freaked out about Ebola because it wasn't super contagious, only a R 1.3. But the mortality rate was 80%. So it would have not died out on it's own, spread extremely slow, but eventually, everyone would get it if left unchecked and 80% of them would die.
