US Covid resurgence driven by younger adults
As of October 2020, individuals aged 20-49 were the only groups sustaining COVID-19 transmission with reproduction numbers well above 1 in the US.
Following initial declines, numbers of COVID-19 cases started to rise again halfway through 2020 in the United States and Europe. In September the team published Report 32 as a pre-print, using age-specific mobility data from across the United states and linking these to age-specific COVID-19 mortality. Their findings pointed out that targeting interventions to adults aged 20-49 could facilitate safe reopening of schools and kindergartens.
Mobility and mortality
The peer reviewed publication in Science today by the Imperial College COVID-19 Response team includes new data up to October 2020. The updated analysis of aggregated age-specific mobility data from more than 10 million individuals in the US, shows that 65 of 100 COVID-19 infections still originated from individuals aged 2

Vaccine programmes in low- and middle-income countries have prevented 37 million deaths in the last 20 years alone – 36 million of which would have been in children aged under-five, according to new research published today in
The research is the most comprehensive study of the impact of vaccination programmes ever. It was conducted by the Vaccine Impact Modelling Consortium (VIMC) – a multinational collaboration of 16 research groups, including experts from the London School of Hygiene & Tropical Medicine (LSHTM
LONDON, Jan 7 ― Children, teenagers and young adults appear to be more affected by the B.1.1.7 variant of Covid-19 initially detected in the UK, then in South Africa, British research reports. Still, the data should not cause alarm to parents, say certain experts, who explain that the youngest.

New COVID-19 variant growing rapidly in England
The new SARS-CoV-2 variant is growing rapidly, is more transmissible than other variants, and affecting a greater proportion of under 20s.
New variant of concern
This higher transmissibility will make control more difficult and further accentuates the urgency of rolling out vaccination as quickly as possible. Professor Neil Ferguson Imperial College COVID-19 Response Team
All viruses undergo genetic changes which are called mutations, and through selection pressure can result in different variants. The variant of SARS-CoV-2 (the virus causing COVID-19) originally termed lineage B.1.1.7, was detected in November 2020 and is rapidly spreading across England. Several genetic changes (substitutions and deletions) have immunological significance and are associated with diagnostic test failures. The absence of S gene target in an otherwise positive PCR test appears to be a highly specific marker for the B.1.1.7 lineage, which h
