RE: Hearhrow Airport to use Rapid Antibody testing.29 May 2020 15:14
I see a thread on twitter on this, im not on twitter, but to continue ...
"Simple question - How would you stop an infected person getting on a plane, going to a football match? going into work?
They are not stopping infected people getting on planes. The safety net is the quarantine period. Fact is they are leaving people to decide if they want to take the risk, the consequence is the quarantine period. Yes they have mitigation methods such as social distancing, hand washing, temperature screening. Quarantine protects the receiving country, not an antigen test. The only way of ensuring a person on a flight is not infected is if they have taken a positive antibody test and have certification. Fact is an antigen test does not stop an infected person getting on a flight. If you had 10,000 passengers going to an airport to a test centre, it could only take one positive person to infect the other 9,999. But the other 9,999 will produce a negative test on the day of infection, so they will be a ticking time bomb for wherever they land.
Football matches - if the risk is high enough to want to test 50 thousand people to let them in a stadium, they simply will remain closed door events. Again how do you congregate a crowd to a testing centre, when one infected person could infect the other 49,999.
Going to work - this is one area when tests could be used on a more regular bases, funded by employers.
Antibody testing is in the government strategy, with certification.
There is a big market for home based antigen tests. It looks like Sano are leading the way with this. But that market is in the likes of boots etc where someone with symptoms can order a test. But the number of these home antigen tests wont be as high as you might think, because infection rate is dropping, more people are getting immunity all the time, and a lot of people are asymptomatic.
