Cases started to rise in March. In January/February we only had 1-2 bad occupied in covid wards ( now it is about 400 with more patients waiting to get admission). This rise may be caused by mix of combined effect of things,@docbroke Funny you say town, I think it's a city already (Rotterdam 651.376, The Hague 547.757 and Amsterdam >800.000 are only twice as big). Do you think the explosion in cases started after the festivals (there is one week where India has lots of celebrations, although not everybody celebrates all of them)
1. Immergence of new strains of the virus
2. Elections in some of the states. Even with death tolls rising, elections were held in west bengal, while complete/partial lockdowns, closed schools, limitied gatherings were in-effect in other states. Hundred-thousands of people gathered in election ralleys without masks in front of PM, homeminister, chiefminister etc.
3. Festivals, ( you may have seen reports of kumbh-mela in haridvar, where about 900 thousand people took dip in holy river ), this was allowed as rulling party favors hindus, and this was one of the biggest hindu festival gathering. PM remained nearly silent about this and election ralleys while talking about covid emergency with grim face.
4. India-England cricket series ( first few test matches were played with 50% ground capacity, but after that 100% ground capacity was used for two one-day matches. Reason being that ground in Ahmedabad was dream project of PM, so he probable wanted inauguration with full glory, for worlds biggest cricket ground. However this was the exact time when cases were rising, and after getting backlashes on social media later matches were played with empty ground)
