Question

Using the SARS-CoV-2 tests , explain the processes required for scaling up production of the newer diagnostic testing in a global pandemic and regulatory processes required for use of new diagnostic tests for COVID-19 within Australia, Europe and the United States of America.

Answer 1

Ans) Infection with the virus causing COVID-19 (SARS-CoV-2) is confirmed by the presence of viral RNA detected by molecular testing, usually RT-PCR.  

- Detection of viral RNA does not necessarily mean that a person is infectious and able to transmit the virus to another person.

- Factors that determine transmission risk include whether a virus is still replication-competent, whether the patient has symptoms, such as a cough, which can spread infectious droplets, and the behavior and environmental factors associated with the infected individual.

- 5-10 days after infection with SARS-CoV-2, the infected individual starts to gradually produce neutralizing antibodies. Binding of these neutralizing antibodies to the virus is expected to reduce the risk of virus transmission.
