Invasive Pneumococcal Disease and Influenza Activity in a Pediatric Population: Impact of PCV13 Vaccination in Pandemic and Nonpandemic Influenza Periods Epidemiology

The objective of this study was to analyze the incidence, clinical presentation, and severity of invasive pneumococcal disease (IPD)-causing serotypes and the impact of the 13-valent pneumococcal conjugate vaccination during epidemic and nonepidemic influenza periods in Catalonia, Spain. This was a prospective study in persons aged

ute; Pierre J. Talbot Respiratory viruses infect the human upper respiratory tract, mostly causing mild diseases. However, in vulnerable populations, such as newborns, infants, the elderly and immune-compromised individuals, these opportunistic pathogens can also affect the lower respiratory tract, causing a more severe disease (e.g., pneumonia). Respiratory viruses can also exacerbate asthma and lead to various types of respiratory distress syndromes. Furthermore, as they can adapt fast and cross the species barrier, some of these pathogens, like influenza A and SARS-CoV, have occasionally caused epidemics or pandem...

Conclusions: Human challenge studies and systems biology approaches are important tools that should be used in concert to advance our understanding of influenza infection and provide targets for novel therapeutics and immunizations. Introduction Although influenza virus was recognized as an important pathogen over a century ago, influenza continues to cause a significant burden of disease. In the United States alone, it's estimated that in the 2017–2018 season there were 959,000 hospitalizations related to influenza illness, and 79,400 deaths (CDC, 2018). Worldwide, WHO estimates that annual influenza...

(CNN) — From climate change to superbugs, the World Health Organization has laid out 10 big threats to our global health in 2019. And unless these threats get addressed, millions of lives will be in jeopardy. Here’s a snapshot of 10 urgent health issues, according to the United Nations’ public health agency: Not vaccinating when you can One of the most controversial recent health topics in the US is now an international concern. “Vaccine hesitancy — the reluctance or refusal to vaccinate despite the availability of vaccines — threatens to reverse progress made in tackling vaccine-prevent...

Authors: Feldman C, Shaddock E Abstract INTRODUCTION: Lower respiratory tract infections (LRTIs) are the leading infectious disease cause of death in the world and the fifth overall cause of death. From an epidemiological point of view, most consider pneumonia, influenza, bronchitis (including acute exacerbations in chronic obstructive pulmonary disease [AECOPD]), and bronchiolitis to be the most important LRTIs. Areas covered: This review will describe the epidemiology of LRTIs in adults focusing on community-acquired pneumonia, influenza, and AECOPD, utilizing data from the more recent literature. Expert commenta...

(NEW YORK) — This nasty flu season, which has been worsening for months, may finally be leveling off. Health officials on Friday said about 1 of every 13 visits to the doctor last week was for fever, cough and other symptoms of the flu. That’s no reason for health officials to celebrate yet: That level is among the highest in a decade. But it’s no worse than last week, and flu activity had been increasing each week since November. The Centers for Disease Control and Prevention report said the number of states reporting heavy flu patient traffic also held steady at 43. “I thought I was going to die,...

In conclusion, influenza A virus infection was detected rather high with a rate of 20.5% in the study group. The monitoring of influenza virus types and subtypes is required for the evaluation of influenza vaccine strains and circulating influenza viruses and for the identification of subtypes with pandemic potential. Planning for appropriate antiviral therapy using real-time RT-PCR in the early diagnosis of influenza virus infections will significantly contribute to the management of the patient's treatment. Thus, unnecessary drug use will be prevented and controlled with effective treatment of the disease at the time of ...

AbstractAssessments of influenza season severity can guide public health action. We used the moving epidemic method to develop intensity thresholds (ITs) for 3 US surveillance indicators from the 2003 –2004 through 2014–2015 influenza seasons (excluding the 2009 pandemic). The indicators were: 1) outpatient visits for influenza-like illness; 2) influenza-related hospitalizations; and 3) influenza- and pneumonia-related deaths. ITs were developed for the population overall and separately for c hildren, adults, and older adults, and they were set at the upper limit of the 50% (IT50), 90% (IT90), and 98% (IT98) 1-...

Abstract Assessments of influenza season severity can guide public health action. We used the Moving Epidemic Method to develop intensity thresholds (IT) for 3 US surveillance indicators from the 2003-04-2014-15 influenza season (excluding the 2009 pandemic): 1) outpatient visits for influenza-like illness, 2) influenza-related hospitalizations, and 3) influenza- and pneumonia-related deaths. ITs were developed for the overall population and children, adults, and older adults separately and were the upper limit of the 50% (IT50), 90% (IT90), and 98% (IT98) one-sided CIs of the geometric mean of each season's 3 hig...

Across China, the virus that could spark the next pandemic is already circulating. It’s a bird flu called H7N9, and true to its name, it mostly infects poultry. Lately, however, it’s started jumping from chickens to humans more readily–bad news, because the virus is a killer. During a recent spike, 88% of people infected got pneumonia, three-quarters ended up in intensive care with severe respiratory problems, and 41% died. What H7N9 can’t do–yet–is spread easily from person to person, but experts know that could change. The longer the virus spends in humans, the better the chance that i...

Since then, clinicians have exercised great care in order to make an early diagnosis of viral pneumonias. This is due in part to pandemic influenza A infection having greater impact on populations
