Summary: This study analyzed the characteristics of influenza incidence in Lanzhou and the impact of meteorological factors on influenza activities. It found that there were more male cases than female cases in Lanzhou, and younger age groups were more susceptible to influenza. The epidemic characteristics showed seasonal peaks and troughs. Meteorological factors such as daily pressure, precipitation, humidity, sunshine, temperature, and wind speed were found to affect the number of influenza cases. The SARIMAX model with average temperature had better predictive performance than the university model.

Summary: This study provides important information for understanding influenza epidemiology and informing influenza vaccine policy. Infants born during influenza epidemics were protected from infection that first year. The mean effective reproduction number across years was 1.2.

Summary: This study shows that older adults with type 2 diabetes mellitus who use metformin as a pre-influenza vaccination have lower risks of hospitalization for influenza, pneumonia, cardiovascular disease, mechanical ventilation, and mortality compared to nonusers of metformin.

Summary: Respiratory failure is a common complication in hospitalized influenza patients, particularly in those with pneumonia and since the 2009 pandemic. However, there is significant heterogeneity in the definition and reporting of respiratory failure, making it difficult to characterize and compare across cohorts and other respiratory viruses.

Summary: For several decades, the World Health Organization has collected, maintained, and distributed valuable country-specific disease surveillance data. By proposing a completeness metric based on effective time series length, researchers explored the association between completeness and health expenditure indicators, observing steady improvements and a correlation between doubling in decadal health expenditure per capita and increased overall completeness. The proposed metric could guide experts in assessing open access data quality and quantity for credible statistical analyses and outbreak forecasting systems.

Summary: This study estimated the clinical and economic burden of severe influenza in Spain using statistical models. The results showed that there is a significant under-detected burden of influenza, especially in the elderly population. The average annual cost of influenza-related hospitalizations was 45.7 million euros, and the average annual mortality rate due to influenza was 27.7 per 100,000 people.

Summary: By employing a generalized linear model, the seasonal and antigenic characteristics of influenza in China from 2005-2017 were studied to inform vaccine recommendations. The study found differences in the seasonal patterns and antigenic similarity of influenza in different regions of China.

Summary: This retrospective study analyzed hospitalized adult RSV and influenza patients in Thailand, revealing that RSV is less common but similar to influenza in terms of complications and mortality. Clinical manifestations are not reliable in distinguishing between RSV and influenza, necessitating laboratory-confirmed diagnosis.

Summary: Exploring the COVID-19 response in New Zealand and comparing it to the 1918-19 influenza pandemic reveals significant improvements in terms of strategic direction, elimination strategy, border restrictions, vaccination rollout, and central government support. However, the lessons from 1918-19 regarding the prevention of inequities among social groups were not fully learned, as demonstrated by the ongoing unequal health outcomes in New Zealand.

Summary: Acute respiratory illness (ARI) caused by viral pathogens is a major cause of morbidity and mortality in Latin America. This study conducted in Colombia provides insights into the clinical burden, severity, and outcomes of respiratory viral infections. The findings highlight the fluctuating incidence of ARI in Colombia, primarily driven by Influenza A, and a high mortality rate.

Summary: Systematic tuberculosis detection at hospital admission did not reduce mortality in children with severe pneumonia. The use of Xpert MTB/RIF Ultra for diagnosis was supported, especially in children with severe acute malnutrition.

Summary: This study conducted a systematic review and meta-analysis to assess the burden of influenza-associated mortality, hospitalization, and outpatient visit in mainland China. The findings suggest that children and the elderly are at higher risk for influenza-related hospitalization and mortality.

Summary: This study used national health insurance claims data from South Korea to evaluate various factors associated with the incidence of hospital-acquired pneumonia (HAP). The results showed that age, gender, pre-existing lung diseases, and certain hospital environmental factors were associated with the incidence of HAP.

Summary: This study found that in older patients aged 75 and over, older age, lower ADL score, and higher SOFA score were associated with death within 30 days after influenza diagnosis. Early initiation of oseltamivir treatment was independently associated with survival.
