During the rapid outbreak the test positivitiy rate also increased rapidly. This has now largely stopped.
I'd interpret this as suggesting that the gap between confirmed cases and total cases was increasing for a long time, but that this isn't continuing anymore.
As we all have now seen many times during the pandemic there is a large delay between changes in cases and changes in deaths.
People get sick before they die.
We should therefore expect that the number of deaths continues to increase before it follows the decline of cases.
It's a very long way down. It's hard to know large the gap between confirmed and total cases is, but estimates for that ratio are commonly much higher than 10.
This means that many millions are getting infected daily and that means that the situation can reverse quickly.
Every tenth person in India has received a first dose of the COVID vaccine and so it's also still a long way until everyone in the population is protected.

Until 50 years ago, CO₂ emissions developed in lockstep with economic growth in France.
Since the early 1970s, the opposite has been true: emissions declined as people in France got richer.
To produce consumption-based CO₂ emissions, statisticians need access to detailed global trade statistics. This data is, therefore, not available over the very long run. But it is available for the last three decades and are shown in this chart.
This is one big reason why France succeeded in this way — the large reduction of fossil fuel electricity.
I don't know how to summarize this post in a thread. But I can share the two visuals I made for it. 👇
• Demographers estimate that 117 billion humans have been born.
• Almost 8 billion are alive now.
To bring these large numbers into perspective I made this visualization.
A giant hourglass. But instead of measuring the passage of time, it measures the passage of people. /2
How does our past and present compare with the future?
We don't know. But what I learned from writing this post is that our future is potentially very, very big.
I try to convey this here. But even this visualization shows only a small fraction of humanity's potential future.
