PCR, Polymerase chain reaction; COVID-19, Coronavirus disease 2019.
Fig 2.
Mean proportion of negative respiratory virus PCR test results according to the level of social distancing (between the 1st week of 2015 and the 42nd week of 2020; a total of 303 weeks) and the mean number of respiratory virus tests according to the level of social distancing (between the 23rd week of 2017 and the 39th week of 2020; a total of 176 weeks).
The horizontal line represents the mean value, and the hollow circle represents the value for each week. PCR, Polymerase chain reaction.
