Potential problem of the co-occurrence of pandemic COVID-19 and seasonal influenza.

Epidemiol Mikrobiol Imunol 2021 ;70(1):68-71

In times of COVID-19 pandemics, the upcoming period of the year when influenza activity usually increases in the Northern Hemisphere brings new medical and public health challenges. These challenges include the risk of mixed infections and/or a possible collision of the two epidemics (“twindemia”) with a potentially serious impact on individual health and public health. In this report, we discuss the results of the published stu-dies and conclude that the catastrophic collision of the seasonal influenza and COVID-19 epidemics is unlikely when efficient non-pharmaceutical public health measures are applied to control or mitigate the spread of the COVID-19 epidemic.

Value of influenza vaccines in cancer patients during the coronavirus (COVID-19) pandemic: a cross-sectional study.

Support Care Cancer 2021 Apr 10. Epub 2021 Apr 10.

Department of Biostatics and Epidemiology, Shahid Sadoughi University of Medical Science, Yazd, Iran.

Background: According to the recommendation of the Centers for Disease Control and Prevention (CDC), getting influenza vaccines during the coronavirus (COVID-19) pandemics is especially important for people with certain underlying medical conditions, like cancer. Due to the similarities between the symptoms of influenza and COVID-19, receiving the flu vaccine in suspicious cases can be helpful because it will make it easier to request a medical test and diagnosis. In this study, the value of influenza vaccination in the cancer population was investigated. Read More

J Med Virol 2021 Mar 30. Epub 2021 Mar 30.

Department of Public Health and Infectious Diseases, University of Rome Sapienza, Rome, Italy.

The role of viruses in community acquired pneumonia (CAP) has been largely underestimated in the pre-coronavirus disease 2019 age. However, during flu seasonal early identification of viral infection in CAP is crucial to guide treatment and in-hospital management. Though recommended, the routine use of nasopharyngeal swab (NPS) to detect viral infection has been poorly scaled-up, especially in the emergency department (ED). Read More

Influenza and other respiratory viral infections associated with absence from school among schoolchildren in Pittsburgh, Pennsylvania, USA: a cohort study.

BMC Infect Dis 2021 Mar 22;21(1):291. Epub 2021 Mar 22.

Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, USA.

Background: Information on the etiology and age-specific burden of respiratory viral infections among school-aged children remains limited. Though school aged children are often recognized as driving the transmission of influenza as well as other respiratory viruses, little detailed information is available on the distribution of respiratory infections among children of different ages within this group. Factors other than age including gender and time spent in school may also be important in determining risk of infection but have been little studied in this age group. Read More

A stacked ensemble method for forecasting influenza-like illness visit volumes at emergency departments.

PLoS One 2021 22;16(3):e0241725. Epub 2021 Mar 22.

Research and Innovation, Provincial Population and Public Health, Alberta Health Services, Calgary, Alberta, Canada.

Accurate and reliable short-term forecasts of influenza-like illness (ILI) visit volumes at emergency departments can improve staffing and resource allocation decisions within hospitals. In this paper, we developed a stacked ensemble model that averages the predictions from various competing methodologies in the current frontier for ILI-related forecasts. We also constructed a back-of-the-envelope prediction interval for the stacked ensemble, which provides a conservative characterization of the uncertainty in the stacked ensemble predictions.

Front Immunol 2021 3;12:642791. Epub 2021 Mar 3.

Department of Infectious Diseases, College of Veterinary Medicine, University of Georgia, Athens, GA, United States.

The overall performance of a multiple component vaccine assessed by the vaccine-elicited immune responses across various strains in a repeated vaccination setting has not been well-studied, and the comparison between adults and teenagers is yet to be made. A human cohort study was conducted at the University of Georgia, with 140 subjects (86 adults and 54 teenagers) repeatedly vaccinated in the 2017/2018 and 2018/2019 influenza seasons. Host information was prospectively collected, and serum samples were collected before and after vaccination in each season. Read More
