Samples from accommodation
(Condominium)

The project collected samples four times. The total number of samples is twenty, all of them are positive. Most importantly, we randomly detected the variance of SARS-CoV-2 virus by using Mass Array technique at the areas where we get the positive result. At that time, the Delta variance was detected which is correlated with the strain of virus in the patient.

Samples from the market

The project collected samples four times. The total number of samples is five, all of them are positive. We randomly detected the variance of SARS-CoV-2 virus, and the results are all Delta variance, which is consistent with the stain breaking out that time.
