COVID-19 testing
diagnostic testing for the respiratory illness COVID-19 and the underlying pathogen SARS-CoV-2 coronavirus / From Wikipedia, the free encyclopedia
COVID-19 testing can help find the SARS-CoV-2 virus. There are two types of test; one can find the virus (i.e. Polymerase chain reaction, also called PCR) and the other that can find antibodies produced in response to infection.
An accurate mortality rate of the disease and the level of herd immunity in the population can be found from the results of these tests. However, it is still not known how long immunity will last, and how effective it will be.[1]
Due to limited testing, as of March 2020, no countries had reliable data of the virus.[2]
