#COVID19 in Delhi. The question is not whether the Delhi govt is underreporting #COVID19 deaths, but by how much? I& #39;ll examine this with press reports and modelling. Conclusion: Delhi #COVID19 transparency is even worse than Maharashtra& #39;s. 1/7
Striking fact today which set this off: 26% of migrant workers returning from Delhi to Bihar tested so far were COVID positive. That& #39;s high, even bearing in mind that this is a population with poor living conditions, and more likely to get the disease. 2/7 https://twitter.com/sanjayjavin/status/1262267513393557505">https://twitter.com/sanjayjav...
In my piece for @TheWireScience on Maharashtra, it was the sudden *drop* in death rate which stood out. I wrote that I hadn& #39;t noticed this in other states. But I hadn& #39;t looked carefully enough at Delhi at the time of writing, and so missed that story. 3/7 https://twitter.com/TheWireScience/status/1261194107776622592">https://twitter.com/TheWireSc...
Here& #39;s what preliminary plots and simulations show for Delhi. From about 17/04/20 there is a marked slowing in deaths. This happens a little earlier in testing data too, but a smaller effect. From 17/04 onwards, reported (red) and predicted (green) #COVID19 deaths diverge. 4/7
Reported Delhi #COVID19 deaths continued to diverge from predictions from 17/04/20 until a correction around 11/05/20. By coincidence (irony alert!), a few days earlier, media outlets started claiming the Delhi govt was underreporting COVID19 deaths. 5/7 https://thewire.in/government/delhi-government-casualty-hospitals-data">https://thewire.in/governmen...
A page with more detail on the simulations + model-based estimation of COVID-19 prevalence in Delhi. E.g., if we assume an infection fatality rate of 0.5%, then there have been to date ~2.5 lakh infections in Delhi, with ~80K of these currently active.

What I understand from this thread: many of the deaths "missing" from Delhi& #39;s official COVID-19 count were actually tested and verified COVID-19 deaths, not just suspected COVID-19 deaths... https://twitter.com/appriseParas/status/1262758352683012097">https://twitter.com/apprisePa...
