Before I start, let me say that I have been doing Data Analytics Studies on the Coronavirus Pandemic for 46 days and have written 111 research-based blog posts on COVID-19 in these 46 days.
Look at the graph of the growth rate and the 5-day moving average in the number of COVID-19 cases and deaths worldwide in the last 15 days. All the data is based as reported at the same time (the previous Midnight UTC/GMT) every day.
Compared to the previous day, the daily growth rate in number of cases went down for 7 consecutive days from April 15 to 21, followed by 3 consecutive days of increases on April 22, 23, and 24. Then there were 3 consecutive days of declines on April 25, 26, and 27. The last 2 days (April 28 and 28) have seen increases compared to the previous day.
What is much more important is the 5-day moving average (“5DMA”), as this shows a trend much better than day-by-day numbers. The 5DMA had 20 consecutive days of declines from April 4 to 23. However, it went up on April 24 and 25, followed by 4 consecutive drops from April 26 to 29. Though the two days of increases after 20 consecutive days of declines was not a good sign, if we look at the 7-day moving average (“7DMA”), this shows 28 uninterrupted days of declines since April 2.
The story with deaths is slightly different. The daily growth graph is going up and down like a see-saw, as the orange line in the graph shows. The 5DMA for deaths has been showing a gradual decline since April 3, except small upticks on April 17 and 24. The 7DMA for deaths also shows 28 uninterrupted days of declines since April 2.
If the disease is indeed on its way out, one big reason is definitely the strict social distancing measures (like lockdown) imposed on over half the world’s population. Who’s to tell what could happen if such measures are lifted or eased — as has already been done or is being discussed — in the countries most affected by Coronavirus, including USA, Spain, Italy, France, Germany, Belgium, Austria, Switzerland, Norway, and Denmark, amongst several others.
I will shortly write a separate post on the subject of the daily, 5DMA and 7DMA trends in cases and deaths in India.
