Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections may be underestimated because of limited access to testing. We measured SARS-CoV-2 seroprevalence in South Africa every 2 months during July 2020–March 2021 in randoml...y selected household cohorts in 2 communities. We compared seroprevalence to reported laboratory-confirmed infections, hospitalizations, and deaths to calculate infection–case, infection–hospitalization, and infection–fatality ratios in 2 waves of infection. Post–second wave seroprevalence ranged from 18% in the rural community children <5 years of age, to 59% in urban community adults 35–59 years of age. The second wave saw a shift in age distribution of case-patients in the urban community (from persons 35–59 years of age to persons at the extremes of age), higher attack rates in the rural community, and a higher infection–fatality ratio in the urban community. Approximately 95% of SARS-CoV-2 infections were not reported to national surveillance.

The article reviews the impact of respiratory syncytial virus (RSV) on global health, emphasizing its significant burden on infants, children, and the elderly. It discusses current and emerging prevention strategies, including the development and implementation of vaccines and monoclonal antibodies.... The review highlights advancements in RSV research, the challenges of creating effective vaccines for different age groups, and the importance of global collaboration to reduce RSV-associated morbidity and mortality. It also calls for increased investment in research and public health measures to enhance prevention and treatment options.

In 2018, approximately 60,000 Ugandans were estimated to be suffering from cancer. It was also reported that only 5% of cancer patients access cancer care and 77% present with late-stage cancer coupled with low level of cancer health literacy in the population despite a wide coverage of primary heal...thcare facilities in Uganda. We aimed to contribute to reducing the unmet needs of cancer prevention and early detection services in Uganda through capacity building.

Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

Civil disorder, authority credibility and public health: Chile’s unique sociopolitical
context in dealing with COVID-19.
The coronavirus outbreak that began in 2019 (COVID-19) threatens to reverse years of hard-won gains in preventing and treating HIV. Fragile health systems are further stressed as health workers navigate an increased client load and demands at work while also being concerned for their own health and ...that of their families. Health facilities have been redesigned to care for patients with COVID-19, posing challenges to other services. Governments and civil society organizations have redirected scarce resources and shifted programming priorities to respond to the pandemic. Several countries have reported intermittent declines in HIV testing and diagnosis, antenatal care visits, collection of antiretroviral medicines (ARVs) by people living with HIV, and attendance at clinic appointments. Community-based education and support programmes have had to rapidly adapt to restrictions on movement and public gatherings. Children, adolescents, and women have experienced multiple deprivations due to the adverse impact of the pandemic.

Project Drawdown (2022) provides evidence of how climate solutions can also be win-win opportunities for meeting development and human well-being needs while boosting prosperity for rural communities in sub-Saharan Africa and South Asia. The report summarizes the co-benefits of five groups of a subs...et of Project Drawdown climate solutions (28 total solutions) for advancing human well-being in rural areas of low- and middle-income countries

This study investigated occupational risk factors and exposure–response relationships for airway disease among health workers (HWs) exposed to cleaning agents in two tertiary hospitals in South Africa and Tanzania.
Previous studies have demonstrated an association between asthma or respiratory... symptoms and exposure to broad categories of cleaning-related exposures in healthcare settings. However, few studies have identified the specific cleaning agents responsible for asthma and other health outcomes. Products used for medical instrument cleaning and disinfection such as glutaraldehyde, orthophthalaldehyde (OPA) and quaternary ammonium compounds (QACs) have been implicated in the causation and exacerbation of work-related asthma (WRA) and upper airway outcomes such as rhinitis.

The crisis caused by the COVID-19 pandemic exacerbated preexisting structural economic inequalities, and had a disproportionate impact on informal workers, especially on women and young people, who lost jobs and income. The situation was even more difficult for single-parent households led by women,... who also had to endure more housework and care tasks. As shown by various research studies, the asymmetric distribution of care tasks, taken up by women, is an inequality factor.
