Covid-19 Science

The science behind the global response to the Covid-19 pandemic

How much more lethal is the Kent virus really?

By Juergen Ude : 12th February 2021

According to reports the Kent Virus could be up to 70% more contagious and 30% more lethal than other countries.

Reported Deaths are slightly higher than for the first wave.

Infections were much higher in the UK during the first wave. We would thus expect deaths to be much higher in the first wave. However reported deaths were higher in the last wave, implying the Kent virus is deadlier.

Figure 3 shows total registered deaths for England and Wales(1) using a distribution Optimized Hybrid SPC Chart(2). This chart was validated with data for the UK from an alternative data source.

The registered deaths show that there was a high number of deaths during the first wave! But There is no evidence of an unusual number of deaths at the time of the second and third wave.

This supports the case positivity data but contradicts the reported deaths. One explanation is that reported deaths are not scientific due to the definition of covid-19 deaths which is based on dying with, not from Covid-19

The reader can decide if the Kent virus is more deadly justifying the worldwide panic and further destruction of human lives.


“According to research published on Dec 29, 2020, by the UK Health Agency Public Health England, the new variant appears to be no worse than the previous dominant strain of SARS-CoV-2 in terms of the risk of hospital admission, severity of illness, or mortality.”
