“…Based on the data available on the NIZP-PZH website [ 13 ], it is known that influenza infections and suspected infections in children account for 30% to 48% of the total number of infections in the last 4 epidemic seasons, 2015–2016 through 2018/2019 [ 11 ]. Similar results were obtained in the epidemic seasons 2014–2015, 2015–2016, and 2017–2018 [ 10 , 15 , 16 ].…”

Background This study aimed to investigate the epidemiology of influenza viruses and viruses that caused influenza-like disease in children under 14 years of age in the 2018–2019 epidemic season in Poland, and to identify the public health lessons that can be learned. Material/Methods Nose and throat swabs were used to obtain samples. The samples were analyzed in the National Influenza Center, Department of Influenza Research at the National Institute of Public Health-National Institute of Hygiene as well as in 16 Voivodship Sanitary Epidemiological Stations across the country. Methods of RNA isolation depended on the laboratory where the isolation was performed. In all laboratories, quantitative polymerase chain reactions were used to determine the influenza virus type as well as the subtype. Results The study group was confirmed to be infected with influenza A and B, with influenza A/H1N1/pdm09 as the dominant subtype. Among the age group of children up to 14 years of age, cases of infection with viruses that cause influenza-like disease were also reported. It was noticeable that the largest number of confirmed cases of infection was recorded in the group of the youngest children (0–4 years). In addition, several different variants of co-infection were registered. Conclusions This population study showed that in the 2018–2019 epidemic season in Poland children aged under 14 years were at risk of influenza virus infection and its complications. The presented data support increasing the percentage of children being vaccinated in Poland.

“…There was a lower incidence of respiratory syncytial virus compared to the preceding 2015/ 2016 season, but the predomination of this virus among all influenza-like viruses was consistent (Cieślak et al 2017). This confirms the notion that respiratory syncytial virus is the most common cause of lower respiratory tract infection among children.…”

“…These data coincide with those provided by other European countries (WHO 2017). This is in contradistinction to the preceding 2015/2016 season when the predominant variant was rather the A/H1N1/pdm09 subtype and when, in the latter part of the season, frequent influenza B types were observed; the finding unseen in Poland in 2016/ 2017 (Cieślak et al 2017). In children aged 0-14 years, 445 cases of influenza and influenza-like viruses were confirmed.…”

“…In case of influenza infection, especially in children, rapid diagnosis is important as it allows the introduction of antiretroviral treatment which should start up to 48 h after onset of symptoms (Brydak 2008). The most precise and efficient method of confirming influenza virus in a test sample consists of molecular biology, be it reverse transcription polymerase chain reaction (RT-PCR) or real-time quantitative transcription polymerase chain reaction (qRT-PCR) (Cieślak et al 2017). However, the method is as yet hardly available in tertiary hospitals.…”

Influenza is an infectious disease that is a common cause of infection among children. The main reason for it is the extremely low percentage of vaccinated people in Poland. In the 2016/2017 epidemic season more than 3,000 tests from children up to age 14 were examined. The dominance of subtype A/H3N2/ (40.9%) was confirmed. The evaluation was stratified by three age groups (0-4, 5-9, and 10-14 years), which revealed significant differences. The highest number of samples was available in the 0-4 years group. The highest percentage of positive samples was present in the 10-14 years group. Influenza-like viral infections, among them the respiratory syncytial virus, were also observed. Children due to immature immunity are at particular risk for influenza. A lack of proper vaccination coverage strongly increases the chance of serious complications of the infection.

“…Children are known to be the population cohort most exposed to influenza and influenza-like infections, and are therefore a very important group in the spread of influenza virus in the population [ 31 ]. Furthermore, the generally low severity of COVID-19 infection in this population is associated with a high incidence of asymptomatic or only mildly symptomatic infection, making children efficient carriers of this condition too.…”

Seasonal influenza causes significant morbidity and mortality, and healthcare-associated disease is particularly problematic as it affects high-risk groups. For this reason, annual vaccination against influenza is generally recommended for all healthcare workers, thereby embracing the twin principles of beneficence and non-maleficence. The cost and burden of influenza vaccination is minimal, and it has been argued that employing institutions are under an obligation to ensure that employees are universally vaccinated. Presenteeism, i.e. reporting for work when unwell, is another significant cause of nosocomial infection and may easily occur as even in the hypothetical ideal situation of 100% vaccination coverage, the influenza vaccine is not 100% effective. This paper reviews the combined benefits of increased vaccination rates and reduced presenteeism rates in healthcare workers, particularly in the event of a winter surge in COVID-19 infections that will result in simultaneous infection with influenza and COVID-19, with potentially severe consequences.
