Introduction Natural disasters are catastrophic events of atmospheric, geological and hydrological origins. These disasters include earthquakes, floods, volcanic eruptions, landslides, tsunamis and droughts. (1) From 1998 to 2017, 1.3 million [...], Objective To assess global, regional and national trends in the impact of floods from 1990 to 2022 and determine factors influencing flood-related deaths. Methods We used data on flood disasters from the International Disaster Database for 1990-2022 from 168 countries. We calculated the annual percentage change to estimate trends in the rates of people affected and killed by floods by study period, World Health Organization (WHO) region, country income level and flood type. We used multivariable logistic regression analysis to assess the factors associated with death from floods. Findings From 1990 to 2022, 4713 floods were recorded in 168 countries, which affected > 3.2 billion people, caused 218 353 deaths and were responsible for more than 1.3 trillion United States dollars of economic losses. The WHO Western Pacific Region had the most people affected by floods (> 2.0 billion), accounting for 63.19% (2 024 599 380/3 203 944 965) of all affected populations. The South-East Asia Region had the most deaths (71 713, 32.84%). The African and Eastern Mediterranean Regions had the highest number of people affected and killed by floods per 100 000 population in 2022. The odds of floods causing more than 50 deaths were significantly higher in low-income countries (adjusted odds ratio: 14.34; 95% confidence interval: 7.46 to 30.04) compared with high-income countries. Numbers of people affected and mortality due to floods declined over time. Conclusion Despite the decreases in populations affected and deaths, floods still have a serious impact on people and economies globally, particularly in lower-income countries. Action is needed to improve disaster risk management and flood mitigation. Objectif Evaluer les tendances mondiales, regionales et nationales relatives a l'impact des inondations entre 1990 et 2022, mais aussi determiner les facteurs influengant les deces causes par ces inondations. Methodes Nous avons exploite les donnees concernant 168 pays et reprises dans la base de donnees internationale sur les catastrophes pour la periode allant de 1990 a 2022. Nous avons ensuite calcule la variation annuelle en pourcentage afin de degager des tendances quant au nombre de personnes touchees, voire tuees par des inondations en fonction de la periode d'etude, de la region telle que definie par l'Organisation mondiale de la Sante (OMS), du niveau de revenu du pays et du type d'inondation. Enfin, nous avons employe une analyse multivariee de regression logistique pour determiner les facteurs associes aux deces en cas d'inondations. Resultats Entre 1990 et 2022, 4713 inondations ont ete recensees dans 168 pays. Elles ont touche plus de 3,2 milliards de personnes, cause 218 353 morts et entraine des pertes economiques superieures a 1,3 billion de dollars americains. La region du Pacifique occidental de l'OMS est celle ou le plus grand nombre d'habitants ont ete affectes par ces phenomenes (> 2 milliards), representant 63,19% (2 024 599 380 / 3 203 944 965) de l'ensemble des populations impactees. C'est la region d'Asie du Sud-Est qui comptait le plus grand nombre de deces (71 713, soit 32,84%). La region Africaine et la region de la Mediterranee orientale denombraient toutes deux la plus grande proportion de personnes touchees et tuees lors d'inondations par 100 000 habitants en 2022. La probability que les inondations soient a l'origine de plus de 50 morts etait nettement plus importante dans les pays a revenu faible (odds ratio ajuste : 14,34; intervalle de confiance a 95% : 7,46 a 30,04) que dans les pays a revenu eleve. Letendue des repercussions et le taux de mortalite des inondations diminuaient au fil du temps. Conclusion Malgre une baisse du nombre de personnes touchees et tuees, les inondations continuent a avoir un impact considerable sur les populations et les economies a travers le monde, surtout dans les pays aux revenus plus faibles. Des actions sont requises pour ameliorer la gestion des risques de catastrophes et la lutte contre les inondations. Objetivo Evaluar las tendencias mundiales, regionales y nacionales del impacto de las inundaciones de 1990 a 2022 y determinar los factores que influyen en las muertes relacionadas con las inundaciones. Metodos Se utilizaron datos sobre catastrofes por inundaciones de la Base de Datos Internacional sobre catastrofes para 1990-2022 de 168 paises. Se calculo la variacion porcentual anual para estimar las tendencias de las tasas de personas afectadas y fallecidas por inundaciones segun el periodo de estudio, la region de la Organizacion Mundial de la Salud (OMS), el nivel de ingresos del pais y el tipo de inundacion. Se utilizo un analisis de regresion logistica multivariable para evaluar los factores asociados a la muerte por inundaciones. Resultados Entre 1990 y 2022, se registraron 4713 inundaciones en 168 paises, que afectaron a >3200 millones de personas, causaron 218 353 muertes y fueron responsables de mas de 1,3 billones de dolares estadounidenses de perdidas economicas. La Region del Pacifico Occidental de la OMS fue la mas afectada por las inundaciones (>2000 millones), con un 63,19% (2 024 599 380/3 203 944 965) de todas las poblaciones afectadas. La Region de Asia Sudoriental fue la que registro mas muertes (71 713, 32,84%). Las regiones de Africa y el Mediterraneo Oriental registraron el mayor numero de personas afectadas y fallecidas por inundaciones por cada 100 000 habitantes en 2022. Las probabilidades de que las inundaciones causaran mas de 50 muertes fueron significativamente mayores en los paises de ingresos bajos (razon de probabilidades ajustada: 14,34; intervalo de confianza del 95%: 7,46 a 30,04) en comparacion con los paises de ingresos altos. El numero de personas afectadas y la mortalidad por inundaciones disminuyeron con el tiempo. Conclusion A pesar de la disminucion de las poblaciones afectadas y de las muertes, las inundaciones siguen teniendo un grave impacto en las personas y las economias de todo el mundo, en especial en los paises con ingresos mas bajos. Es preciso actuar para mejorar la gestion del riesgo de catastrofes y la mitigacion de las inundaciones. [phrase omitted]

The human monkeypox has become a public health problem globally. Google Trends Index (GTI) is an indicator of public attention, being potential for infectious disease outbreak surveillance. In this study, we used lag‐correlation analysis to evaluate the spearman correlation coefficients between public attention and monkeypox epidemic by −36 to +36 days‐lag in top 20 countries with most cumulated cases until September 30, 2022, the meta‐analyses were performed to pool the coefficients of countries among all lags. We also constructed vector autoregression model and Granger‐causality test to probe the significance of GTI in monkeypox forecasting. The strongest spearman correlation was found at lag +13 day (r = 0.53, 95% confidence interval: 0.371–0.703, p < 0.05). Meta‐analysis showed significantly positive correlation when the lag was from −12 to +36 day, which was most notable on the third posterior day (lag +3 day). The pooled spearman correlation coefficients were all above 0.200 when the lag ranged from +1 to +20 day, and the causality of GTI for daily case was significant in worldwide and multiple countries. The findings suggested a robust association between 13‐days‐priority GTI and daily cases worldwide. This work introduced a potential monitor indicator on the early warning and surveillance of monkeypox outbreak. [ABSTRACT FROM AUTHOR]

Research assessing the changing epidemiology of infectious diseases in China after the implementation of new healthcare reform in 2009 was scarce. We aimed to get the latest trends and disparities of national notifiable infectious diseases by age, sex, province, and season in China from 2010 to 2019. The number of incident cases and deaths, incidence rate, and mortality of 44 national notifiable infectious diseases by sex, age groups, and provincial regions from 2010 to 2019 were extracted from the China Information System for Disease Control and Prevention and official reports and divided into six kinds of infectious diseases by transmission routes and three classes (A–C) in this descriptive study. Estimated annual percentage changes (EAPCs) were calculated to quantify the temporal trends of incidence and mortality rate. We calculated the concentration index to measure economic‐related inequality. Segmented interrupted time‐series analysis was used to estimate the impact of the COVID‐19 pandemic on the epidemic of notifiable infectious diseases. The trend of incidence rate on six kinds of infectious diseases by transmission routes was stable, while only mortality of sexual, blood‐borne, and mother‐to‐child‐borne infectious diseases increased from 0.6466 per 100 000 population in 2010 to 1.5499 per 100 000 population in 2019 by 8.76% per year (95% confidence interval [CI]: 6.88–10.68). There was a decreasing trend of incidence rate on Class‐A infectious diseases (EAPC = −16.30%; 95% CI: −27.93 to −2.79) and Class‐B infectious diseases (EAPC = −1.05%; 95% CI: −1.56 to −0.54), while an increasing trend on Class‐C infectious diseases (EAPC = 6.22%; 95% CI: 2.13–10.48). For mortality, there was a decreasing trend on Class‐C infectious diseases (EAPC = −14.76%; 95% CI: −23.46 to −5.07), and an increasing trend on Class‐B infectious diseases (EAPC = 4.56%; 95% CI: 2.44–6.72). In 2019, the infectious diseases with the highest incidence rate and mortality were respiratory diseases (340.95 per 100 000 population), and sexual, blood‐borne, and mother‐to‐child‐borne infectious diseases (1.5459 per 100 000 population), respectively. The greatest increasing trend of incidence rate was observed in seasonal influenza, from 4.83 per 100 000 population in 2010 to 253.36 per 100 000 population in 2019 by 45.16% per year (95% CI: 29.81–62.33), especially among females and children aged 0–4 years old. The top disease with the highest mortality was still AIDs, which had the highest average yearly mortality in 24 provinces from 2010 to 2019, and its incidence rate (EAPC = 14.99%; 95% CI: 8.75–21.59) and mortality (EAPC = 9.65; 95%CI: 7.71–11.63) both increased from 2010 to 2019, especially among people aged 44–59 years old and 60 or older. Male incidence rate and mortality were higher than females each year from 2010 to 2018 on 29 and 10 infectious diseases, respectively. Additionally, sex differences in the incidence and mortality of AIDS were becoming larger. The curve lay above the equality line, with the negative value of the concentration index, which indicated that economic‐related health disparities exist in the distribution of incidence rate and mortality of respiratory diseases (incidence rate: the concentration index = −0.063, p < 0.0001; mortality: the concentration index = −0.131, p < 0.001), sexual, blood‐borne, and mother‐to‐child‐borne infectious diseases (incidence rate: the concentration index = −0.039, p = 0.0192; mortality: the concentration index = −0.207, p < 0.0001), and the inequality disadvantageous to the poor (pro‐rich). Respiratory diseases (Dec–Jan), intestinal diseases (May–Jul), zoonotic infectious diseases (Mar–Jul), and vector‐borne infectious diseases (Sep–Oct) had distinct seasonal epidemic patterns. In addition, segmented interrupted time‐series analyses showed that, after adjusting for potential seasonality, autocorrelation, GDP per capita, number of primary medical institutions, and other factors, there was no significant impact of COVID‐19 epidemic on the monthly incidence rate of six kinds of infectious diseases by transmission routes from 2018 to 2020 (all p > 0.05). The incidence rates of six kinds of infectious diseases were stable in the past decade, and incidence rates of Class‐A and Class‐B infectious diseases were decreasing because of comprehensive prevention and control measures and a strengthened health system after the implementation of the new healthcare reform in China since 2009. However, age, gender, regional, and economic disparities were still observed. Concerted efforts are needed to reduce the impact of seasonal influenza (especially among children aged 0–4 years old) and the mortality of AIDs (especially among people aged 44–59 years old and 60 or older). More attention should be paid to the disparities in the burden of infectious diseases. [ABSTRACT FROM AUTHOR]
