I have been conducting Data Analytics Studies on the Coronavirus Pandemic for 101 days and have written 159 research-based blog posts on COVID-19 in these 101 days.
Positivity Rate is the percentage of those who have tested positive for Covid-19 out of all people who have been tested.
Look at the graph. India had a cumulative Positivity Rate of just 3.97% on May 17, which has now gone up to 5.95%, an increase of almost 50% in just 33 days. The average Positivity Rate for these 33 days is 7.01%, which has resulted in this huge rise in the cumulative rate.
Why is India’s Positivity Rate going up? In my mind, it is because of 2 reasons: (1) Many more tests are being carried out — average 145,594 tests per day in the past 15 days, compared with average 115,355 tests per days in the 15 days prior to that; and (2) more tests are being carried out by private labs as opposed to a higher percentage being carried out by government labs earlier.
If this is true, it could only mean that private labs’ testing is more accurate than that of government labs. While most people would just believe this on face value, when you consider that the average Positivity Rate of the Top 20 countries (in number of cases) is 7.28%, it becomes even more believable.
India carried out an average of 168,519 tests per day in the past 3 days and recorded an average Positivity Rate of 8.24%. At the same rate, India will cross 500,000 cases in 7.5 days and 750,000 cases in 25.5 days, by which time it would have overtaken Russia to reach the global No.3 rank in number of cases, after USA and Brazil.
However, if we believe the government that the national testing rate will be ramped up to 200,000 tests per day — which now looks like a fair possibility given that we have crossed the threshold of 175,000 daily tests yesterday — and assuming that the Positivity rate remains at 8.24%, India will cross 750,000 cases in 21.5 days and one million cases in 37 days. Yes, India is now staring at the real possibility of recording over 1,000,000 (10 lakh) Covid-19 cases before the end of July.
Since May 17, India’s lowest daily Positivity Rate was 5.29% on May 20, and the highest was 8.68% on June 15. The average for the 19 days in June has been 7.63%.
In comparison, the country with most cases — USA — has a cumulative Positivity Rate of 8.47% and the country with the second highest number — Brazil — has a cumulative Positivity Rate of 9.19%. However, Russia’s cumulative Positivity Rate is just 3.49%, but that may be because Russia has tested 111,846 people per million residents, compared with USA’s 80,759 and Brazil’s 50,341. India has only tested 4,659 people per million.
