The overlap of coronavirus disease 2019 (COVID-19) with other common respiratory pathogens may complicate the course of the disease and prognosis. The aim of the study was to evaluate the rates, characteristics, and outcomes of pediatric patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), respiratory syncytial virus (RSV), influenza A/B infections, and their coinfections. A single-center prospective cross-sectional study was performed at the pediatric emergency department in Vilnius from 1 October 2021 to 30 April 2022. In total, 5127 children were screened for SARS-CoV-2, RSV, and influenza A/B. SARS-CoV-2 PCR tests were positive for 21.0% of children (1074/5127). The coinfection rate of respiratory viruses (RSV, influenza A) in patients with COVID-19 was 7.2% (77/1074). Among the 4053 SARS-CoV-2 negative patients, RSV was diagnosed in 405 (10.0%) patients and influenza A/B in 827 (20.4%) patients. Patients with COVID-19 and coinfection did not have a more severe clinical course than those with RSV or influenza infection alone. RSV and SARS-CoV-2 primarily affected younger patients (up to 2 years), while the influenza was more common in older children (4–10 years). Patients infected with RSV were more severely ill, reflected by higher hospitalization proportion and need for respiratory support.

Background/Objectives: Acute upper respiratory tract infections (URIs) are defined as inflammatory diseases of the nose, sinuses, pharynx, larynx, or trachea. They are common in children. The prescription of antibiotics for the treatment of URIs became a relevant theme in the scientific literature in recent decades. One of the most important ways to deal with increasing antimicrobial resistance is rational antibiotic therapy. This study aimed to evaluate the tendencies of antibiotic prescribing practices for Lithuanian children with URIs from 2018 to 2022. We describe how many children with URIs were prescribed antibiotics, which antibiotics were used, and whether prescribing practices meet national guidelines. Methods: Secondary data, which were used in this observational study, were collected from the Lithuanian Compulsory Health Insurance Fund (CHIF) electronic records. The study population consisted of children aged between 0 and 18 years who visited their primary care doctors (pediatricians or family doctors) between January 2018 and December 2022 and were prescribed antibiotics for the treatment of URIs. Results: Between 2018 and 2022, there were 445,328 visits reported when antibiotics, which belong to the J01 group according to the Anatomical Therapeutic Chemical Classification (ATC), were prescribed to children aged 0–18. In more than half of the visits (51.70%), children aged 0–5 were consulted. Penicillins were mostly prescribed for the treatment of acute nasopharyngitis. Macrolides were mostly used to treat acute laryngitis and tracheitis. Of all penicillin-class antibiotics, the most popular choice was amoxycillin. The primary choice of cephalosporin was cefadroxil, and the primary choice of macrolide was clarithromycin. Conclusions: During the period of 2018–2022, the number of prescriptions for antibiotics for URTIs decreased, but prescriptions for penicillin-class antibiotics increased in a relative manner. The most common diagnoses during these visits were acute tonsillitis and acute pharyngitis, and most antibiotic prescriptions were for children in the 0–5 age group. If Lithuania’s National Recommendations on the Rational Use of Antibiotics were implemented during the analyzed period, the prescribing tendencies would not meet them.

Background: Data from recent years show that the COVID-19 pandemic has significantly reduced the scope of child immunisation worldwide. If the numbers continue to fall, we may have a vaccination crisis. In order to understand the local factors of this phenomenon, we studied parents‘ viewpoint towards childhood vaccination in Lithuania. Therefore, the aim of our study was to determine the impact of parental attitudes on children’s vaccination.Materials and Methods: A web-based cross-sectional study was made in Lithuania from October 20th to November 3rd, 2020, using Google Forms. An anonymous questionnaire included both quantitative and qualitative questions. The questionnaire was distributed to the general population in Lithuania via social media and a snowball sampling. Only parents who have at least one child under 18 years old were involved in the study. We analysed the parents’ attitudes towards vaccination by their socioeconomic and demographic determinants using MS Excel and OpenEpi tools. The respondents were considered vaccine supporters if they vaccinated all their children with state-reimbursed vaccines or only vaccinated some of their children, and vaccine sceptics if they did not vaccinate their children with state-reimbursed vaccines.Results: The population of our research consisted of 775 parents. There were more males against vaccination than females, respectively, 59.6% and 33.2%. 65.0% of all respondents stated that they vaccinated their children with the full course of vaccines, while the remaining 35.0% did not vaccinate. University-level education dominated in both pro-vaccine and anti-vaccine groups. We found that 16.9% of parents who were unvaccinated as children themselves tend not to vaccinate their children. However, in the pro-vaxx group, only 0.7% of parents were unvaccinated during childhood. 50.8% of vaccine sceptics were not fully informed by healthcare professionals about the benefits and risks of vaccination, while only 31.6% of vaccine supporters were not informed. Social environment did not have an impact on the decision whether to vaccinate or not to vaccinate a child among both vaccine advocates and vaccine deniers (accordingly, 51.2% and 42.9%). 29.3% of respondents stated that the cost of paid vaccinations was too high. Open-text survey responses gave us more in-depth insight about the parental decision-making process. Protection of children and society from infectious diseases (31.7%) was mentioned as the main reason for vaccination. Whereas vaccine-hesitant parents were mostly concerned about already-occurring side effects or their risk (43.4%).Conclusions: Our findings confirmed that vaccine hesitancy was associated with not being vaccinated in childhood themselves, lack of information from medical practitioners and male gender. The price of vaccines also had an impact on immunisation rates – more than one-third of the vaccine supporting parents indicated that the cost of paid vaccinations was too high. The main incentive for vaccine compliance was parents’ desire to protect their children and society from infectious diseases. Whereas vaccine-hesitant parents were mostly concerned about already occurring side effects or their risk. There was no consensus, whether vaccination of children should be mandatory in Lithuania, as the answers to the question were almost evenly distributed. The formation of parents‘ attitudes towards children‘s vaccination is a complex process that is determined by parents‘ attitudes towards the health care system, lack of trust in doctors, and gaps in communication about the benefits and risks of vaccination. All of this information should be taken into account in health policy-making.
