Here in Maryland, population about 6 million, there are about 23,000 confirmed cases and a little over a thousand deaths. A bit more than half of the deaths are patients in nursing homes. We are mostly in lockdown. We can shop for groceries, go to the hardware store, such things as that, wearing a mask.
There were 1730 new cases in the last 24 hours. This is nearly an 8% increase and was a shock. The percentage increase has mostly been under 5 % for maybe the last ten days or so. I hope the 8% is an anomaly.
This would mean that in Maryland, the death toll is at about 170 per million inhabitants.
The Netherlands has 17 million inhabitants. Since March 1st, the Covid-19 reported deaths are 260 per million. These are people who have been tested positive. They typically died in hospitals or at home after they had been diagnosed in the hospital. However, in that period the excess mortality is 520 per million. (The excess mortality is the number of people who died in that period more than you would have expected to die, based on the average in the same period from the previous 5 years.) So, in the Netherlands roughly half of the corona victims were tested. (Some people will have died from secondary effects of the corona crisis, think of heart attacks due to stress).
The number of hospitalizations (people who are or have been in hospital beds with confirmed or suspected corona) is now at 638 per million inhabitants. These numbers are also available on a local level. The region where I live has been hit hard. There is county nearby (about 25 miles from us) with 3247 hospitalizations per million. We have 1784 per million in the county where we live. The Northern part of the country is hardly affected. (The distance from North to South is about 200 miles.)
The national number of hospitalizations has increased with 5 per million (+ 0.8 %) in the last 24 hours. Here, we are definitely over a peak. We have very little data on test results, because we don't have the testing material.
Typically, health care workers are tested, as a sample for the population, and the data are collected. Some of the blood donations are tested for antibodies to collect data on (possible) immunity. My estimate is that roughly 5-10 % of the population has antibodies now.
To me this means that we will have to be in our "intelligent lockdown" for another 1-1.5 year. (3.5% immunity built up per month, 60 % needed - 7.5 that we have: 52.5/3.5= 15 months) The lockdown could be lifted gradually in this period, working similarly like an annuity. This would mean that the output numbers (casualty rate, hospitalization rate, etc.) remain constant whereas the number of contacts between people gradually increases (but the number of contacts with people who are not immune stays constant).
So, I have prepared myself mentally to have to deal with this for 1-1.5 years. I guess that this means that face to face bridge will start again after the summer of 2021.
