The 2009 H1N1 influenza virus is responsible for the first influenza pandemic of the 21st century. Within 5 months after its emergence in Mexico, it had affected more than 290,000 patients and caused at least 3486 deaths on 6 continents. This report provides information about influenza viruses, previous pandemics, and the virology, clinical features, and epidemiology of 2009 H1N1 influenza in order to elucidate the current pandemic and outline the questions that remain.

Chile is a South American country that spans 4,300 km from north to south. Population density and access to critical care are highly concentrated in Santiago's metropolitan region. After the educational challenges posed by the 2009 H1N1 influenza pandemic, our critical care department at the Pontificia Universidad Católica de Chile in Santiago created the Respiratory Therapy Postgraduate Certificate as an educational intervention to address the shortage of healthcare professionals with knowledge and skills in performing respiratory support in critically ill patients.

Influenza A viruses (IAVs) pose a major public health threat due to their wide host range and pandemic potential. Pigs have been proposed as "mixing vessels" for avian, swine, and human IAVs, significantly contributing to influenza ecology. In the United States, IAVs are enzootic in commercial swine farming operations, with numerous genetic and antigenic IAV variants having emerged in the past two decades.

Influenza surveillance is important for monitoring influenza virus circulation and disease burden to inform influenza prevention and control measures. The aim of this study was to describe the epidemiology and to estimate the incidence of influenza in two communities in West Java, Indonesia, before and after the 2009 H1N1 pandemic. A population-based surveillance study in the community health care setting was conducted to estimate the annual incidence of influenza.

Background: We continue to struggle with the prevention and treatment of the influenza virus. The 2009 swine flu pandemic, caused by the H1N1 strain of influenza A, resulted in numerous fatalities. The threat of influenza remains a significant concern for global health, and the development of novel drugs targeting these viruses is highly desirable.

Influenza forecasts could aid public health response as shown for temperate regions, but such efforts are more challenging in the tropics and subtropics due to more irregular influenza activities. Here, we built six forecast approaches for influenza in the (sub)tropics, with six model forms designed to model seasonal infection risk (i.e.
