ad to any symptoms, but—among the unvaccinated—between 1 in 50 and 1 in 500 infections result in paralysis. For some it leads to death.
At the start of the 20th century, polio was endemic worldwide, with large epidemic outbreaks every year. But with the development of two vaccines in the 1950s, countries began eliminating polio one by one.

Estimated annual number of deaths from alcohol and drug use disorders per 100,000 people. These include only direct deaths from thesedisorders, meaning they do not include suicide deaths which can in some cases be connected or attributed to them.
Alcohol has historically, and continues to, hold an important role in social engagement and bonding for many. Social drinking or moderate alcohol consumption for many is pleasurable.
However, alcohol consumption – especially

in excess – is linked to a number of negative outcomes: as a risk factor for diseases and health impacts, crime, road incidents, and, for some, alcohol dependence.
This topic page looks at the data on global patterns of alcohol consumption, patterns of drinking, beverage types, the prevalence of alcoholism, and consequences, including crime, mortality, and road incidents.

Southern Hemisphere and remote regions. Here we report an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

...
in Mexico, describe observed and predicted trends in services over 24 months, and to estimate the number of visits lost through December 2020.
METHODS: We used health information system data for January 2019 to December 2020 from the Mexican Institute of Social Security (IMSS), which provides health services for more than half of Mexico's population-65 million people. Our analysis includes nine indicators of service use and three outcome indicators for reproductive, maternal and child health and non-communicable disease services. We used an interrupted time series design and linear generalised estimating equation models to estimate the change in service use and outcomes from April to December 2020. Estimates were expressed using average marginal effects on the risk ratio scale.
RESULTS: The study found that across nine health services, an estimated 8.74 million patient visits were lost in Mexico. This included a decline of over two thirds for breast and cervical cancer screenings (79% and 68%, respectively), over half for sick child visits and female contraceptive services, approximately one-third for childhood vaccinations, diabetes, hypertension and antenatal care consultations, and a decline of 10% for deliveries performed at IMSS. In terms of patient outcomes, the proportion of patients with diabetes and hypertension with controlled conditions declined by 22% and 17%, respectively. Caesarean section rate did not change.
CONCLUSION: Significant disruptions in health services show that the pandemic has strained the resilience of the Mexican health system and calls for urgent efforts to resume essential services and plan for catching up on missed preventive care even as the COVID-19 crisis continues in Mexico.

ct of air pollution on health and the environment. It presents data on sources of pollution, such as industry, vehicles, and domestic energy use, and highlights the associated health risks, including respiratory and cardiovascular diseases. The site emphasizes that air pollution is one of the leading environmental risk factors for premature deaths worldwide, particularly affecting low- and middle-income countries. It also discusses trends in air pollution levels over time and the effectiveness of policy interventions in reducing pollution and improving public health.

in-depth analysis of cardiovascular diseases (CVD), the leading cause of death globally. It examines CVD trends, such as the decline in mortality rates in high-income countries due to improved healthcare and lifestyle changes, while low- and middle-income countries experience rising CVD burdens. The article highlights major risk factors, including high blood pressure, obesity, smoking, and poor diet. It emphasizes the importance of preventive measures and access to treatment to reduce global disparities in CVD outcomes. The data-driven approach uses visualizations to illustrate the global impact and distribution of CVD.
