We know that COVID-19 is bad in Maharashtra. But how bad? How prevalent is COVID-19 in Mumbai? Has it peaked? Is it going to be over any time soon? I ran some simulations and found the data is consistent with several futures. 1/ #covid19maharashtra https://mumbaimirror.indiatimes.com/coronavirus/news/maharashtras-covid-19-cases-rise-to-44582-mumbais-count-crosses-27000-mark/articleshow/75899784.cms">https://mumbaimirror.indiatimes.com/coronavir...
First some estimates. Modelling suggests there have been ~4000 deaths in Maharashtra and ~2.2 million infections. If two thirds are in Mumbai, then around 8% of Mumbai& #39;s 18M population have had COVID-19. (London: 17% & NY: >21%)

Maharashtra& #39;s estimated cases are based on an assumed infection fatality rate of 0.5%. Official deaths are 1576, but I corrected for systematic undercounting of COVID-19 deaths which began in mid-April. I discussed this in an article earlier. https://science.thewire.in/health/covid-19-mumbai-comorbid-fatality-criteria-missing-deaths-modelling/">https://science.thewire.in/health/co...
So, are we nearing peak in Maharashtra? Modelling finds (unhelpfully) maybe, maybe not! Maharashtra& #39;s infections curve is disappointingly "straight". It could be flattening a bit. Four scenarios assuming a 0.5% fatality rate - with pictures - to follow...
#covid19maharashtra scenarios:
1. (Optimistic) Already peaked at about 0.76M infectious cases.
2. Peak end May at about 0.92M infectious cases.
3. Peak early-mid June at about 1.4M infectious cases.
4. (Pessimistic) Still no peak in mid-June. Almost 4M infectious cases by then.
