CLEAN : Aussie sewers a frontline in bid to flush out coronavirus

The video tutorial emphasizes the importance of vigilance and large-scale screening to detect undetected cases or re-emergence of diseases. It highlights the cost-effectiveness of testing compared to clinical surveillance, while noting that it does not replace clinical methods. The process involves collecting samples, storing them at low temperatures, and using RTPCR to quantify the virus. Tracing positive results back to specific areas, not individual houses, is also discussed.

What is the primary goal of large-scale population screening in the context of COVID-19?

• To find undetected cases or re-emergence

• To replace clinical testing

• To reduce the number of health departments

• To increase the cost of testing

How does wastewater surveillance help in managing COVID-19?

• By replacing clinical surveillance

• By providing data to target clinical surveillance

• By eliminating the need for testing

• By increasing the number of positive cases

What is the role of RT-PCR in wastewater surveillance?

• To store samples at minus 20 degrees

• To quantify the virus in sewage

• To collect samples from sewer lines

• To trace results back to individual houses

How are positive results from wastewater samples traced?

• To random locations

• To entire cities

• To specific areas or suburbs

• To individual houses

What is done with the samples after they are collected from sewer lines?

• They are stored in the lab for testing

• They are sent to individual houses

• They are used for clinical testing

• They are discarded
