Differences between the first wave and this one range from survival chances to the use of public transport.
This time around more women are affected but under 60s are faring better, figures from NHS England show.
Those without health problems are also doing better in the third wave than in the first.
People with no known health problems when they were infected by the virus made up 5 per cent of 25,080 deaths in the first wave and 3 per cent of 12,125 deaths in the third.
And those under 60 made up 8.7 per cent of deaths in the spring, whereas this winter they account for only 5.9 per cent of deaths.

More good news is the survival chances of hospital patients with Covid-19 are thought to be higher now than at the beginning of the pandemic thanks to treatments such as the steroid dexamethasone.
Test and Trace has also changed its definition of ‘close contact’, which was previously defined as anyone who has been within two metres of someone for a single period of at least 15 minutes.
Now it is anyone who has been within two metres of someone for more than 15 minutes, whether in a single period or cumulatively over the course of one day.
When it comes to public compliance, data from transport app Citymapper shows people living in London, Manchester and Birmingham are planning more journeys by public transport now than in the first lockdown.
Journeys during the first lockdown fell to less than 10 per cent of pre-pandemic levels compared to just under 20 per cent of pre-pandemic levels in the third lockdown.
Dr David Strain, a senior clinical lecturer at the University of Exeter, told the Sun of potential hypotheses as to why the trend is shifting.
Speaking of a change in the virus, he told the Mirror: “If we imagine everyone has a certain threshold of viral tolerance.
“If the amount of virus they come into contact with is above that threshold the exposure turns into the disease.
“Now the virus is more virulent, you need much lower amount to cause the infection, therefore people who previously were unlikely to catch the disease before (young fit women) are suddenly vulnerable.”
On Tuesday, Health Secretary Matt Hancock said the UK’s Covid-19 pandemic is at its worst point and hospitals won’t get quieter until February.
Hancock told the Downing Street press conference: “We’re at the worst point of this pandemic.”
NHS England Medical Director Professor Stephen Powis added: “We are not going to see reductions in admissions until February.”
Coronavirus rates are highest for those in their 20s in England as infections soar in every region of the country, said Public Health England in last week’s Covid-19 surveillance report.
Rates have increased across all age groups, with the highest rate – 842.5 cases per 100,000 people – seen in those aged 20 to 29.
It is up from 603.6 the previous week.
The highest hospital admission rates continue to be those aged 85.
Among 30 to 39 year-olds the rate rose from 621.2 to 813.0, and for 40 to 49-year-olds it rose from 589.0 to 737.8.
Case rates for 10 to 19-year-olds stood at 434.8, up from 356.8.
The lowest rates were recorded among those aged four and under (193.9) and five to nine (206.0).
