The course of the UK COVID 19 pandemic; no measurable impact of new variants

Abstract: Introduction In November 2020, a new SARS-COV-2 variant or the Kent variant emerged in the UK, and became the dominant UK SARS-COV-2 variant, demonstrating faster transmission than the original variant, which rapidly died out. However, it is unknown if this actually altered the overall course of the pandemic as genomic analysis was not common place at the outset and other factors such as the climate could alter the viral transmission rate over time. We aimed to test the hypothesis that the overall observed vir… Show more

“…That VOC are more transmissible is based on mathematical modeling, and not certain (111). Another mathematical model showed that the course of the UK pandemic was not altered by the emergence of the B.1.1.7 VOC (112).…”

“…If accurate, a 30-60% increase in case fatality rate would mean Emergency Management principles are even more important to protect the older population, as the infection fatality rate would still be very low in younger people [since there would be no difference in relative risk increase by age (111,112,114)], and the cost-benefit balance still very strongly favor no lockdowns.…”

“…47 Another study found that the course of the pandemic in the UK was not altered by the VOC B.1.1.7. 48 Second, that VOC are more lethal. 49 This is based on UK studies that used the same data on identified community cases, and had limitations, including that over 50% of cases were missing from the analysis, only 9% of deaths in the UK over the time period were included in the analysis, and the lack of adjustment for co-morbidities.…”

“…That VOC are more transmissible is based on mathematical modelling, and not certain (107). Another mathematical model showed that the course of the UK pandemic was not altered by the emergence of the B.1.1.7 VOC (108). That VOC are more deadly is based on studies that used the same UK data, excluded >50% [and even more of the deaths] of the population from analyses for 'missingness', included only 8% of UK COVID-19 deaths, did not control for co-morbidities as a confounder, and only examined case fatality rate (109,110).…”

“…The recent surge in India with the delta VOC still (as of April 30, 2021) had India ranked in cases and deaths per capita at 114 th and 116 th in the world, and (on April 30, 2021) with daily deaths per million (1.95) and total deaths per million (151) lower than in the European Union (4.68 and 1548 respectively) and worldwide (1.65 and 408 respectively) (113). If accurate, a 30-60% increase in case fatality rate would mean Emergency Management principles are even more important to protect the older population, as the infection fatality rate would still be very low in younger people (since there would be no difference in relative risk increase by age (107,108,110)), and the cost-benefit balance still very strongly favor no lockdowns. Current vaccines are effective for the UK B.1.1.7 VOC.…”
