No testing program is ever 100% perfect.
But testing with accurate tests will be crucially important along with other factors that may be in place for some businesses and/or companies such as taking temperatures when reporting to work, for example.
The infection rate for this virus is 2.5, meaning that each infected person can infect another 2.5 people. And then each one of those 2.5 people spread it to another 2.5 individuals. Kinda hard to think about half a person, but statistically that is how they figure the infection rate.
So if I am employer with some type of manufacturing plant that employs 1,000 people, just one employee that has the infection can lead to a total of 406 people with the virus in 30 days if no other protocols are put in place to prevent transmission. So more than a third of my workforce is now infected as a result of just one person that had the virus.
If I put mitigation factors in place to reduce the exposure to my employees aimed at reducing the infection rate to 1.25, then the number of infections for 30 days for one person drops to 15.
Even if there is an employee that tested negative does contract the disease later and goes on to develop the infection, if I have temperature checks in place, hopefully the temp check will trigger another required test. Along with not allowing the employee to report into work, contact testing would then take place testing all individuals that had contact with that one person within the past 1-2 weeks.
No doubt there will be clusters that develop. But with adequate testing they can get in there and test and also do contact testing.
A major reason that not only adequate supplies of testing materials needs to be available, but they also need the manpower to do all the contact tracing.
And @Hoovermom, when they give the number of 150,000-240,000 deaths....that is if nothing is done to slow the transmission of the disease. Guess everyone overlooks that print at the bottom of the slide. If a country does nothing, that is the potential death range.
Put mitigation factors in place and you reduce that number. Just like the example above. The infection rate drops to 1.25 from 2.5. And that saves lives.
