Corona Cases in Delhi are declining but only on paper.

Delhi govt conducting more tests but test reports are highly unreliable and it is giving a false sense that corona cases are declining in Delhi. In fact, RT-PCR tests are more reliable tests to ascertain positivity of corona ;however Delhi Govt has been deliberately using antigen tests, which can be conducted faster and cheaper but it's results are unreliable, as it tends to identify large number of cases as negative, which infact turn out to be  positive, when repeated through RT-PCR tests.

In Delhi, since 18th June, testing has increased. Almost 2.8 lakh tests have been conducted but same have been conducted through antigen testing and not RT-PCR. Out of 2.8 lakh tests through antigen testing almost 7% , approx. 20,000 were found to be positive. Ideally, for remaining, 2.6 lakh persons, whose tests were found to be negative, RT-PCR tests should have been repeated, however RT-PCR tests were conducted for 1365 persons, not 2.6 lakh persons. Out of repeat tests for 1365 persons, 18% tests were found to be positive.

Now, we can realize, Delhi CM inorder to give a false sense of decline in cases, has resorted to antigen tests. On paper, testing has increased, positive cases tend to be declining but in reality situation is not improving.
