29th the rapid detection of new coronavirus antigens approved by the WHO has entered Brazil, which is expected to increase the speed of detection in the country.
This new detection method can determine whether it has been infected at the early stage of transmission.
According to a Brazilian infectious disease scientist, rapid antigen testing is more accurate than the widely used polymerase chain reaction (PCR) test, but it does not mean non-compliance with epidemic prevention regulations.
Washing hands frequently, wearing masks, and maintaining social distance are still the most effective prevention and control methods. At present, private laboratories in Brasilia, the capital of Brazil, have begun to use rapid antigen detection methods.
In September, WHO has announced that it will provide 120 million new coronavirus antigen rapid test reagents for low- and middle-income countries, and stated that the test reagents are low cost and convenient to use, which will help expand the scope of testing and improve the efficiency of diagnosis and treatment.
