Thing about communist regimes, you're naive if you're giving them ANY benefit of the doubt about telling the truth.
I believe there is a lag between initial infection and the point that the body has reacted and gone crazy producing antibodies. During this period you are infected but the test can't detect it yet. The test relies on the body having noticed the illness and ramped up the immune response - again that is my understanding. They know how long the disease takes to incubate. They wait until the last sick person isn't communicable any more, count off that incubation period, and if nobody is showing symptoms after that, they let them out. Not an expert on immunology so I should probably stop talking there. I know the rules for quarantine are hundreds of years old and are dictated by the World Health Organization globally by international treaty. It isn't designed to be a flexible or responsive system - preventing epidemics is placed above the needs or wants of a limited number of infected individuals.
Of course,it's manis. The commies said so. They never lied to us about this virus , right? Oh,wait...
Apart from what Ottomaton said (this is still an antigen test and not an antibody), even the most advanced countries have very limited capacity to test. Until yesterday the UK could only test 100 people a day...now they can test 1000. This is their maximum capabillity after sharing technology, using every lab in the country and every trained personel. That's why Japan announces the results from the cruiseship also in batches..50 - 50 every day..they cannot test everyone fast. This is very ominous about what will happen when the pandemic reaches here, and there are thousands of cases every day.
Somewhat anecdotally, the flu test has like a 20% false negative rate, or something like that. My daughter and I are recovering from the flu, and we both initially tested negative, only to (wisely) go back in the next day and test positive..
Were you vaccinated? Our head of health services, let us know yesterday, that the flu vaccine this year was defected and offers very limited protection. 44% of already vaccinated got the flu anyway. Get well soon.
Yeah - I was more thinking that we know they are testing people on the cruise ship. However many those are, if they test negative, they could release them. If you could get 50 people off that ship every day, that would be better than saying "we think you're good, but back to the infestation zone for you". But as several people have mentioned, that doesn't work if they test can't accurately and fully clear people. It would be nice if they could get a 2nd cruise ship and move people from one to the other as they test negative to at least try to get all the negative people together and have lower risk of spreading things, but that's probably not particularly viable or a priority.
They say the antibody test kit is in the works and should be released soon. Antibody tests are much more sensitive. I hope it is also faster and easier to get the results but I have no clue about that.
It's loose in Singapore and circulating the population. They have cases now with no ability to trace to travel or any known clusters. The cat is out of the bag on this one.
China needs to quit ****ing eating exotic animals. The SARs strain of the coronavirus also came from people in China eating Civets
Um, it is about the people in charge. We have a President that has told around 15,000 lies since he has been in office. The people around him are no better. They lied about the Detention centers on the border. You think they would tell truth in a similar situation? Hell no.
"Those NASTY people are the only ones that need to worry about getting sick. Avoid people from SHITHOLE countries and don't eat Chinese food. My African-American friends should not worry because your Unemployment rate is the lowest in History. We are stopping the Mexicans are the border with my Big Beautiful Wall because many of them are infected. If you vote me in November, you won't get sick!". - Donald J. Trump
Singapore is a police city state that if you chew a gum you are named a gangster and thrown to prison and protests are prohibited. Of course their leader will try to do everything to keep the people calm, oppressive regimes like that are the ones in the most danger of losing control.
