ABSTRACT Introduction Several non-pharmaceutical interventions such as physical distancing, hand washing, self-isolation, and schools business closures, were implemented in British Columbia (BC) following the first laboratory-confirmed case of coronavirus disease 2019 (COVID-19) on January 26, 2020, to minimize in-person contacts that could spread infections. The BC COVID-19 Population Mixing Patterns survey (BC-Mix) was established a surveillance system measure behaviour contact patterns over time inform timing easing/re-imposition control measures. In this paper, we describe BC-Mix design demographic characteristics respondents. Methods ongoing repeated online launched September 2020. Participants are mainly recruited through social media platforms (including Instagram, Facebook, YouTube, WhatsApp). A follow up is sent participants two four weeks after completing baseline survey. Survey responses weighted BC’s population by age, sex, geography, ethnicity obtain generalizable estimates. Additional indices material deprivation index, residential instability, economic dependency, others generated using census location data. Results As July 2021, 61,000 received which 41,375 eligible for analysis. Of participants, about 60% consented 27% provided their personal health numbers linkage with healthcare databases. Approximately 50% respondents female, 39% 55 years or older, 65% identified white had at least university degree.

Abstract Background In the absence of medical treatment and vaccination, individual behaviours are key to curbing spread COVID-19. Here we describe efforts collect attitudinal behavioural data disseminate insights increase situational awareness inform interventions. Methods We developed a rapid collection monitoring system based on cross-national online survey, “COVID-19 Health Behavior Survey”. Respondent recruitment occurred via targeted Facebook advertisements in Belgium, France, Germany, Italy, Netherlands, Spain, United Kingdom, States. investigated how threat perceptions COVID-19, confidence preparedness organisations deal with pandemic, adoption preventive social distancing associated respondents’ demographic characteristics. Results analysed 71,612 questionnaires collected between March 13-April 19, 2020. found substantial spatio-temporal heterogeneity across countries at different stages pandemic control strategies place. Respondents rapidly adopted use face masks when they were not yet mandatory. observed clear pattern perceptions, sharply increasing from personal level national global levels. Although comparatively low, all respondents significantly increased hand hygiene. gender-specific patterns: women showed higher lower healthcare system, more likely adopt behaviours. Finally, also that older people perceived themselves, while strongly concerned about their family. Conclusions Rapid population surveys conducted allow us monitor changes, protective measures, compliance recommended practices. As progresses new waves infections threatening reality, timely crucial guide decision-making process.

Abstract Physical distancing measures are intended to mitigate the spread of COVID-19, even though their impact on social contacts and disease transmission remains unclear. Obtaining timely data contact patterns can help assess such protective measures. We conducted an online opt-in survey based targeted Facebook advertising campaigns across seven European countries (Belgium, France, Germany, Italy, Netherlands, Spain, United Kingdom (UK)) States (US), achieving a sample 53,708 questionnaires in period March 13–April 13, 2020. Post-stratification weights were produced correct for biases. Data numbers, as well behaviour perceived level threat collected used expected net reproduction number by week, R t , with respect pre-pandemic data. Compared reported prior mid-April daily numbers had decreased between 49% Germany 83% ranging from below three per day UK up four Netherlands. Such reductions sufficient bring one or all countries, except Germany. Evidence US showed that mainly after governments issued first physical guidelines. Finally, although uniformly age groups, older adults lowest contacts, indicating higher levels protection. provided comparable set statistics during COVID-19 pandemic eight high-income disaggregated week. As these estimates offer more grounded alternative theoretical assumptions often epidemiological models, scientific community could draw this information developing realistic epidemic models COVID-19.
