So how do they know so many people have antibody. Also other thread you were refering one forth of Delhi population has heard immunity. Does it mean they got the infection and recovered or some of the family members got infected and others were not so it's been assumed that they got immunity. What's the basis of these finding.

There is a story on bbc. It shows state by state data graphically.  Data as per them shows there has been consistent decline in daily recorded infections in Delhi NCR for last 7+ days, while it is still increasing rest of Indian states.
 

iMO, recorded infection is nothing but displaying a percentage of actual infections. Going by that, I believe, Mid August, recorded infecTiins will go down for all of India. 15 -20 more days left. Delhi Mumbai and othe metros are allready coming out off woods.

 

PS: percentage of people with antibodies is measured by antibodies among random sampling among population

So did they test that many people for antibodies?

57% of mumbai slumdwellers must be around 6 million people.. You can assume they took a representative sample size of 10 people for that and tested 10% among them for lack of testing infrastructure as they might have had to send the samples to national super dooper firatclass testing laboratory located in murshidabad.

 out of 21k people in Delhi who's blood was tested for antibodies, 5k had them.

 

This was representative of the entire 2 crore population as these 21k were methodically chosen from various areas and age groups proportionately.

 

Likewise, in Mumbai they tested 7-8k people.

So, this calculation is just mathematical.

So looks like it's just assumption based on sample data which might or might not be correct. We came across similar kind of finding that how 3 lockdown one after another ll flatten the curve by various researchers in March month when lockdown were imposed.

^ Actually best data is recorded death rate (not Recorded death due to Coronavirus). This value does not lie. For example, number of deaths in UK and US, during peak period was allmost double the deaths compared to last year in same month. It is back to near similar compared to previous year now for UK. Dont know about US.

 

This death rate is not being published live for India, however, I read somewhere few days back. As per that Mumbai had peaked daily deaths sometime in June.

Yes death rate is a good indicator but then again how many are correctly attributed is a question.

Yes, we are simply looking at how may died. its overall death rate. This value after reaching the peak, generally has sharp decline. 
 

Yesterday, they compared it for Whole EU, and found UK had highest increase in overall death.
 

when India publishes recorded death  of 2020. it will be interesting one as the YoY difference is probably actaul corona death

Not true in case of India. Large number of accidental deaths, workplace deaths or even death from pollution happen. Many of these deaths are now reduced to 25-50% . Unless you have data on actual natural deaths you cannot take total number of deaths as flawless method. Even for big cities natural deaths is not a good indicator as large number of people from small cities , villages come for treatment. Many do die naturally in this process.

Its same for every country. However the reduction in death say due to pollution because people managed to breath cleaner air for few months is not going to be significant enough. Number of people dieing on Road because of accident vs dieng on accident due long march from Mumbai to UP can be used against going data by data. Ie When natural death number is in hundreds of thousand, trend cant be dismissed. So globally, I agree with people that its difference in deaths YoY can be directly blamed to corona, even if that meant someone died cos he didnt reach to Hospital ICU because of lockdown
