UK variant transmission Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the capacity to generate variants with major genomic changes. The B.1.1.7 (also known as VOC 202012/01) many mutations that alter virus attachment and entry into human cells. Using a variety of statistical dynamic modeling approaches, Davies et al. characterized spread in United Kingdom. authors found is 43 90% more transmissible than predecessor lineage but saw no clear evidence for change disease...
A novel SARS-CoV-2 variant, VOC 202012/01 (lineage B.1.1.7), emerged in southeast England November 2020 and is rapidly spreading towards fixation. Using a variety of statistical dynamic modelling approaches, we estimate that this variant has 43–90% (range 95% credible intervals 38–130%) higher reproduction number than preexisting variants. fitted two-strain transmission model shows will lead to large resurgences COVID-19 cases. Without stringent control measures, including limited closure...
Background During the Coronavirus Disease 2019 (COVID-19) pandemic, United Kingdom government imposed public health policies in England to reduce social contacts hopes of curbing virus transmission. We conducted a repeated cross-sectional study measure contact patterns weekly from March 2020 2021 estimate impact these policies, covering 3 national lockdowns interspersed by periods less restrictive policies. Methods and findings The survey data were collected using online surveys...
BackgroundBetter accessibility for emergency obstetric care facilities can substantially reduce maternal and perinatal deaths. However, pregnant women girls living in urban settings face additional complex challenges travelling to facilities. We aimed assess the geographical of three nearest functional public private comprehensive 15 largest Nigerian cities via a novel approach that uses closer-to-reality travel time estimates than traditional model-based approaches.MethodsIn this...
To investigate disparities in full immunization coverage across and within 86 low- middle-income countries.In May 2015, using data from the most recent Demographic Health Surveys Multiple Indicator Cluster Surveys, we investigated inequalities - i.e. one dose of bacille Calmette-Guérin vaccine, measles three doses vaccine against diphtheria, pertussis tetanus polio or countries. We then temporal trends level inequality such eight each World Organization's regions, it appeared that about...
BackgroundAn estimated 23 million infants are still not being benefitted from routine immunization services. We assessed how many children failed to be fully immunized even though they or their mothers were in contact with health services receive other interventions.DesignFourteen countries Demographic and Health Surveys Multiple Indicator Cluster carried out after 2000 coverage for DPT (Diphtheria-tetanus-pertussis) vaccine below 70% selected. defined full (FIC) as having received one dose...
England's COVID-19 response transitioned from a national lockdown to localised interventions. In rising cases, these were supplemented by restrictions on contacts (the Rule of Six), then 10 pm closing for bars and restaurants, encouragement work home. These quickly followed 3-tier system applying different in localities. As cases continued rise, second was declared. We used survey quantify the impact epidemiologically relevant contacts.
PurposeDespite efforts to expand contraceptive access for young people, few studies have considered where women (age 15–24) in low- and middle-income countries obtain modern contraceptives how the capacity content of care sources used compares with older users.MethodsWe examined first source respondents' current method using most recent Demographic Health Survey since 2000 33 sub-Saharan African countries. We classified providers according sector (public/private) provide a range short-...
Abstract Background SARS-CoV-2 dynamics are driven by human behaviour. Social contact data of utmost importance in the context transmission models close-contact infections. Methods Using online representative panels adults reporting on their own behaviour as well parents one children, we collect mixing (CoMix) various phases COVID-19 pandemic over 20 European countries. We provide these timely, repeated observations using an platform: SOCRATES-CoMix. In addition to providing cleaned datasets...
Abstract England has experienced a heavy burden of COVID-19, with multiple waves SARS-CoV-2 transmission since early 2020 and high infection levels following the emergence spread Omicron variants late 2021. In response to rising cases, booster vaccinations were accelerated offered all adults in England. Using model fitted more than 2 years epidemiological data, we project potential dynamics infections, hospital admissions deaths December 2022. We consider key uncertainties including future...
Most countries have enacted some restrictions to reduce social contacts slow down disease transmission during the COVID-19 pandemic. For nearly two years, individuals likely also adopted new behaviours avoid pathogen exposure based on personal circumstances. We aimed understand way in which different factors affect - a critical step improving future pandemic responses.The analysis was repeated cross-sectional contact survey data collected standardized international study from 21 European...
The SARS-CoV-2 transmission dynamics have been greatly modulated by human contact behaviour. To curb the spread of virus, global efforts focused on implementing both Non-Pharmaceutical Interventions (NPIs) and pharmaceutical interventions such as vaccination. This study was conducted to explore influence COVID-19 vaccination status risk perceptions related number social contacts individuals in 16 European countries.
Monitoring inequalities based on subnational regions is a useful practice to unmask geographical differences in health, and deploy targeted, equity-oriented interventions. Our objective describe, compare contrast current methods of measuring regional inequality. We apply selection summary measures empirical data from four low- or middle-income countries highlight the characteristics overall performance different measures. use Demographic Health Surveys conducted Bangladesh, Egypt, Ghana...
