This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
SARS-CoV-2 emerged in the UK in January 2020 and the Government introduced national lockdowns and regional tiers to control virus transmission. As the outbreak continued, new variants were detected. We analysed spatio-temporal dynamics of positive tests for COVID-19 on Teesside, UK throughout 2020, in relation to socio-economic deprivation, weather, and Government interventions. We used a combination of disease mapping and mixed-effect modelling to investigate the dynamics of positive tests from two sampling strategies and the spread of particular variants of the virus as they emerged on Teesside. SARS-CoV-2 spread was related to the extent of social deprivation, lockdown interventions and weather. SARS-CoV-2 spread faster in some lineages than others, with positive tests related to levels of socio-economic deprivation. The interventions appeared to have different effects in the two waves of disease, and were associated with reduced numbers of records in the first wave, but having no effect during the second. ARTICLE SUMMARY LINERegional spread of SARS-CoV-2 is dependent on weather, socio-economic and mandatory lockdowns, but the effectiveness of the latter varies with virus lineage.
