Trends in Online Search Activity and the Correlation with Daily New Cases of Monkeypox among 102 Countries or Territories.

Research assessing the trend in online search activity on monkeypox (mpox) and the correlation with the mpox epidemic at the global and national level is scarce. The trend of online search activity and the time-lag correlations between it and daily new mpox cases were estimated by using segmented interrupted time-series analysis and Spearman correlation coefficient (rs), respectively. We found that after the declaration of a Public Health Emergency of International Concern (PHEIC), the proportion of countries or territories with increasing changes in online search activity was lowest in Africa (8.16%, 4/49), and a downward trend in online search activity was highest in North America (8/31, 25.81%). The time-lag effect of global online search activity on daily new cases was significant (rs = 0.24). There were eight countries or territories with significant time-lag effect; the top three countries or territories were Brazil (rs = 0.46), United States (rs = 0.24), and Canada (rs = 0.24). Interest behavior in mpox was insufficient, even after the declaration of PHEIC, especially in Africa and North America. Online search activity could be used as an early indicator of the outbreak of mpox at the global level and in epidemic countries.

COVID-19 pandemic in BRICS countries and its association with socio-economic and demographic characteristics, health vulnerability, resources, and policy response.

BACKGROUND: Little attention has been paid to the comparison of COVID-19 pandemic responses and related factors in BRICS (Brazil, Russia, India, China, and South Africa) countries. We aimed at evaluating the association of daily new COVID-19 cases with socio-economic and demographic factors, health vulnerability, resources, and policy response in BRICS countries. METHODS: We conducted a cross-sectional study using data on the COVID-19 pandemic and other indicators of BRICS countries from February 26, 2020 to April 30, 2021. We compared COVID-19 epidemic in BRICS countries and analyzed related factors by log-linear Generalized Additive Model (GAM) models. RESULTS: In BRICS countries, India had the highest totally of confirmed cases with 18.76 million, followed by Brazil (14.45 million), Russia (4.81 million), and South Africa (1.58 million), while China (0.10 million) had the lowest figure. South Africa had the lowest rate of administered vaccine doses (0.18 million) among BRICS countries as of April 30, 2021. In the GAM model, a 1 unit increase in population density and policy stringency index was associated with a 5.17% and 1.95% growth in daily new COVID-19 cases (P < 0.001), respectively. Exposure-response curves for the effects of policy stringency index on daily new cases showed that there was a rapid surge in number of daily new COVID-19 cases when the index ranged from 0 to 45. The number of infections climbed slowly when the index ranged from 46 to 80, and decreased when the index was above 80 (P < 0.001). In addition, daily new COVID-19 cases (all P < 0.001) were also correlated with life expectancy at birth (-1.61%), extreme poverty (8.95%), human development index (-0.05%), GDP per capita (-0.18%), diabetes prevalence (0.66%), proportion of population aged 60 and above (2.23%), hospital beds per thousand people (-0.08%), proportion of people with access to improved drinking water (-7.40%), prevalence of open defecation (0.69%), and annual tourist/visitor arrivals (0.003%), after controlling other confounders. Different lag structures showed similar results in the sensitivity analysis. CONCLUSIONS: Strong policy response is crucial to control the pandemic, such as effective containment and case management. Our findings also highlighted the importance of reducing socio-economic inequalities and strengthening the resilience of health systems to better respond to public health emergencies globally.

Prevalence of toothache in Chinese adults aged 65 years and above.

OBJECTIVES: To investigate the prevalence of toothache and its risk indicators in the older Chinese population. METHODS: National cross-sectional survey data on 25 048 Chinese people ≥65 years in 2011, 2014 and 2018 survey year were analysed and then pooled. Chi-square test was used to examine the differences in prevalence among specific subgroups. Multivariate modified Poisson regression analyses with robust error variances were used to detect related factors and prevalence ratios (PR) were calculated. RESULTS: The prevalence of toothache was 16.3% (95% CI: 15.5%-17.1%), 12.8% (95% CI: 12.0%-13.7%) and 16.0% (95% CI: 15.3%-16.7%) in years 2011, 2014 and 2018. In the pooled multivariate Poisson regression model, factors associated with toothache were female (PR: 1.27, 95% CI: 1.18-1.37), younger age (PR: 1.84, 95% CI: 1.63-2.09), currently married and living with spouse (PR: 1.08, 95% CI: 1.01-1.15), current living in urban area (PR:1.12, 95% CI: 1.06-1.20), enough financial support (PR: 0.69, 95% CI: 0.65-0.74), having chronic disease (PR: 1.46, 95% CI: 1.35, 1.57), higher sugar intake (PR: 1.10, 95% CI: 1.03-1.17), salty flavour (PR:1.15, 95% CI: 1.07-1.23), smoking (PR: 1.14, 95% CI:1.06-1.23) or drinking (PR: 1.17, 95% CI: 1.09-1.25), with denture (PR: 1.15, 95% CI: 1.08-1.22) and higher toothbrushing frequency (PR: 1.25-1.50). CONCLUSIONS: More than one in ten older Chinese population had toothache, and it was related to age, gender, socioeconomic status, behaviour and oral health status. Lifestyle interventions should be taken to avoid the occurrence of the toothache.
