“…Furthermore, 96.9% of the caregivers only knew the COVID-19 virus was airborne but did not know that it could also be transmitted through contact, such as by sharing dishes and chopsticks or by using public living articles [ 18 ]. Regarding behavior, the respondents generally perform poorly, e.g., failing to cover their mouth and nose while coughing or sneezing (4.41 ± 0.57), which is consistent with the findings of other authors [ 19 ]. These findings suggest that the caregivers still lack knowledge about infection prevention and control, thus manifesting as neglect of home disinfection (4.35 ± 0.275), home ventilation (4.62 ± 0.331), and closed treatment of secretions (3.91 ± 0.431), etc.…”

Objective: This study aimed to investigate the healthcare knowledge, attitudes, and behaviors of primary caregivers of newborns with coronavirus disease 2019 (COVID-19) during the pandemic in Chongqing, China, and analyze the influencing factors. Methods: The study included primary caregivers of COVID-19 newborns hospitalized in our institution from December 2022 to January 2023. A questionnaire survey was initiated to assess the caregivers' health-care knowledge, attitudes, and behaviors for COVID-19 and the influencing factors. The data were analyzed statistically. Results: A total of 195 caregivers were included, one for each infant with COVID-19. The questionnaire consisted of three dimensions. For the knowledge dimension, the top scoring items were wearing masks in public spaces (4.92 ± 0.087), strengthening hand hygiene (4.83 ± 0.164), and frequent ventilation in living environment (4.62 ± 0.331) in order; for the attitude dimension, the top three scoring items were wearing masks in public spaces (4.85 ± 0.353), strengthening hand washing and disinfection (4.72 ± 0.450), and regular ventilation (4.49 ± 0.501). For the behavior dimension, the top three were confidence in winning the challenge of the pandemic (4.71 ± 0.480), standardized wearing of masks in public spaces/confined spaces (4.68 ± 0.589), and high satisfaction with community epidemic prevention measures (4.67 ± 0.496). Among the influencing factors, fear of COVID-19 was the independent risk indicator for the caregivers' anxiety (OR = 38.085, 95% CI = 14.383-100.664) and fear of COVID-19 (OR = 8.170, 95%CI = 2.156-30.957) and fever (OR = 10.213, 95% CI = 1.972-52.892) were the independent risk indicators for depression. Conclusion: The study shows a key link between caregiver knowledge, attitudes, behaviors, and neonatal COVID-19 infection, with a gap between knowledge, attitudes, and behaviors. Caregivers, especially those dealing with premature infants, worried about mother-to-child transmission and experienced multiple births, face significant psychological stress during this phase of the pandemic.

“…The National Health Insurance Service (NHIS) is the universal insurance provider in Korea that is managed by the government and covers 97% of the Korean population (~50 million people) ( 11 , 12 ). During the COVID-19 pandemic, the Korean government encouraged people to get tested for COVID-19 without delay by subsidizing the cost of diagnosis and treatment for individuals who met criteria related to COVID-19 and provided health insurance services to all Koreans with COVID-19 (NHIS-2022-1-623) ( 13 ). The NHIS database therefore includes medical data for all patients who underwent SARS-CoV-2 testing.…”

ObjectivesPrevious studies suggested that coronavirus disease 2019 (COVID-19) could lead to pulmonary fibrosis, but the incidence of newly diagnosed interstitial lung disease (ILD) after COVID-19 is unclear. We aimed to determine whether COVID-19 increases the risk of newly diagnosed ILD and whether vaccination against COVID-19 can reduce this risk.MethodsThis retrospective cohort study used data from the Korean National Health Insurance claim-based database. Two study groups and propensity score (PS)-matched control groups were constructed: Study 1: participants diagnosed with COVID-19 (COVID-19 cohort) and their PS-matched controls; Study 2: COVID-19 vaccinated participants (vaccination cohort) and their PS-matched controls.ResultsIn Study 1, during a median 6 months of follow-up, 0.50% of the COVID-19 cohort (300/60,518) and 0.04% of controls (27/60,518) developed newly diagnosed ILD, with an incidence of 9.76 and 0.88 per 1,000 person-years, respectively. The COVID-19 cohort had a higher risk of ILD [adjusted hazard ratio (aHR), 11.01; 95% confidence interval (CI), 7.42–16.32] than controls. In Study 2, the vaccination cohort had a lower risk of newly diagnosed ILD than controls (aHR, 0.44; 95% CI, 0.34–0.57).ConclusionUsing nationwide data, we demonstrated that COVID-19 was associated with a higher incidence rate of newly diagnosed ILD, but that this risk could be mitigated by COVID-19 vaccination.

The main aim of the following study is to review current knowledge on Influenza. Influenza, also known as the flu, is an acute, infectious disease which attacks the respiratory system. The disease is caused by the influenza virus, of which there are 3 types. The most common is type A of influenza virus. It is transmitted between people by the droplet route, with cases occurring particularly frequently during seasonal epidemics. This is why the most important form of prevention is maintaining personal hygiene and isolation of sick people. Another form of prevention is a vaccine for the influenza virus developed with new variants every year. The flu causes a variety of symptoms from many systems but can also be asymptomatic. Diagnosis of the illness is based on clinical criteria and the results of diagnostic tests for which there are established criteria of legitimacy. Most common and sufficient curation for an illness is a symptomatic treatment but there is also a causal treatment for influenza. However certain conditions are required for its implementation. Influenza is usually a mild disease, but there are present cases of serious complications. Groups particularly exposed to severe and complicated courses of the disease are pregnant women, children and patients with multimorbidities. Currently, the co-occurrence of influenza with Covid-19 infection is particularly dangerous, which constitutes a new challenge for the global health care system.
