The pandemic has launched a data storm. But some numbers cut through this white out. Despite following the numbers closely I was shocked by the following headline on the front on The Washington Post a few weeks ago.

Using data from the Worldometer Website, I thought it would be interesting see how other countries compare with the USA. America has already dropped below this grim marker. And low is not the way to go!!!!
NUMBER OF DEATHS IN COVID PANDEMIC
FIRST WORLD COUNTRIES
WORST: Peru 1: 170
BEST: New Zealand 1: 200,000
Here are some more stats:

London yesterday. Spectators give a spontaneous standing ovation to Oxford Professor Sarah Gilbert (below), who was one of the scientists involved in developing the Astra-Zeneca vaccine and one of 100 key worker special guests on opening day. (The Age, 29 JUN, 2021)

Here are the Covid-19 Vaccination stats for the UK as of yesterday:
BBC, 29 JUN 2021
The UK recorded 22, 868 cases yesterday, but only 3 deaths.
The last time the UK recorded close to 23,000 cases was on 16 December 2020. That day, 613 deaths were announced. (The Age, 29 JUN 2021)
In 2019, in the UK, the total death toll was 616,014 or 1688 per day. Tragically but realistically elderly patients with multiple health issues are more likely to contract Covid and die from complications exacerbated by Covid-19 but not necessarily caused by the virus.
The death toll numbers are now encouragingly low in the UK despite the high infection rates from the highly contagious Covid Delta variant.
UPDATE:
On 9 July 2021, the UK recorded 35,707 cases and 29 Deaths. According to Worldometer stats (below), the case numbers and deaths are still rising. Too soon to celebrate even though the UK Freedom Day is only 10 days away.

Mathspig has tracked the Covid 19 Stats through the Worldometer tracker and calculated the AVERAGE NO. DEATHS per day at the 50, 60, 70, 80, 100 , 200 DAY and the 1 YEAR mark ..
and now at the 500 DAY mark.


Note: Approx 1/3 of deaths around the world are due to accidents, diseases other than Covid, or suicide.

According to the AstraZeneca Media Release, 22 March 2021, “The AstraZeneca US Phase III trial of AZD1222 demonstrated statistically significant vaccine efficacy of 79% … based on 32,449 participants accruing 141 symptomatic cases of COVID-19. The trial had a 2:1 randomisation of vaccine to placebo.”




“A careful review of all available safety data of more than 17 million people vaccinated in the European Union (EU) and UK with COVID-19 Vaccine AstraZeneca has shown no evidence of an increased risk …”



Update:
An updated company analysis of the coronavirus vaccine developed by AstraZeneca and the University of Oxford showed that the two-shot regimen was robustly effective — 76 percent at preventing symptomatic illness — according to a news release from the drugmaker late Wednesday.
Among people 65 and older, the vaccine was 85 percent effective, the company reported.

UK plus & 30 EU countries have administered 34 million AstraVeneca doses and report a blood clot condition in 222 patients and 18 fatalities.
Risk Factor for blood clots = 1: 153,000
Risk of death ~ 1: 2,000,000
Many countries including Australia advise the use of the AstraZeneca vaccine for the 50+ age group as the blood clot condition appears mostly in younger patients.

Mathspig has been tracking the Covid 19 Stats through the Worldometer tracker and calculating the AVERAGE NO. DEATHS per day at the 50, 60, 70, 80,, 100 and now, the 200 DAY mark. The average is still rising which, as the average started low, is not good news. What can I say? Mask Up, folks.
MATHSPIG is reporting in from lockdown in MELBOURNE, Australia, where mask-wearing outdoors is now compulsory, there is an 8pm-5am curfew and travelling more than 5km from your residence is banned.

Day 100 of World Wide Covid-19 data.
Finally, the New York Times published graphs that show the severity of the Coronavirus death rate compared with average weekly death rates. Here is the graph for New York City, which shows during the peak of the Covid-19 Crisis there were 6,000 more deaths per week than expected from the average weekly death rate, which was approx. 1,000.
The death rate was 6 times the average death rate. That is a terrifying statistic and explains why we are all in lockdown or are slowly coming out of lockdown. Meanwhile, in the rest of the world death tolls are still increasing.

Excellent Covid-19 stats update here.

Many statisticians are using 3-day and 7-day averages to track the Covid-19 death and infection rates worldwide.
Mathspig is using the total average of deaths per day since stats were first published from 22 JAN 2020. When this average drops … that will be a sign for cautious optimism. But not yet!!!!

If no preventative measures were taken by governments around the world then we could have been looking at a Plague Worse Case Scenario here.
