“…They are probably due to the persistence of fibrotic interstitial abnormalities, whereas non-fibrotic ones are more likely to recover even after two years. Therefore, according to van Beek [32], CT is not a completely perfect tool for assessing lung function because in the course of COVID-19-as mentioned earlier-there are also abnormalities in the field of microcirculation, contributing to heterogeneous ventilation and perfusion, which is impossible to assess using thin-section computed tomography. Therefore, other more accurate imaging methods should be used, such as dual-energy CT, enabling the study of perfusion, or hyperpolarized pulmonary xenon 129 (129Xe) MRI scans to assess possible limitations in oxygen transfer [33,34].…”

Background/Objectives: Coronavirus disease 2019 (COVID-19) course may differ among individuals—in particular, those with comorbidities may have severe pneumonia, requiring oxygen supplementation or mechanical ventilation. Post-COVID-19 long-term structural changes in imaging studies can contribute to persistent respiratory disturbance. This study aimed to investigate COVID-19 sequels affecting the possibility of persistent structural lung tissue abnormalities and their influence on the respiratory function of peripheral airways and gas transfer. Methods: Patients were divided into two groups according to severity grades described by the World Health Organization. Among the 176 hospitalized patients were 154 patients with mask oxygen supplementation and 22 patients with high-flow nasal cannula (HFNC) or mechanical ventilation. All tests were performed at 3, 6, and 9 months post-hospitalization. Results: Patients in the severe/critical group had lower lung volumes in FVC, FVC%, FEV1, FEV1%, LC, TLC%, and DLCO% at three months post-hospitalization. At 6 and 9 months, neither group had significant FVC and FEV1 value improvements. The MEF 25–75 values were not significantly higher in the mild/moderate group than in the severe/critical group at three months. There were weak significant correlations between FVC and FEV1, MEF50, MEF 75, plethysmography TLC, disturbances in DLCO, and total CT abnormalities in the severe/critical group at three months. In a mild/moderate group, there was a significant negative correlation between the spirometry, plethysmography parameters, and CT lesions in all periods. Conclusions: Persistent respiratory symptoms post-COVID-19 can result from fibrotic lung parenchyma and post-infectious stenotic small airway changes not visible in CT, probably due to persistent inflammation.

“… Kebede et al (2020b) in another study also stated that the transmission rate of the disease has increased rapidly. In spite of the available vaccines against the virus, the emergence of new strains and variants of the virus continues to pose global health challenges ( Mohammed et al , 2022 ; van Beek, 2023 ). According to Bates et al (2021) preventive measures must be adopted to curb the spread of COVID-19.…”

Background The global impact of coronavirus disease 2019 (COVID-19)has led to the need to prioritise public health campaign by all stakeholders among diverse population groups. This study investigated the dispositions of Nigerian adolescents towards the prevention of the spread of COVID-19. Methods The young adolescents (n=1,529) included in this study, were between the ages of 15 and 26 years from Afe Babalola University. Students were contacted through their various colleges and residential hostels to complete the questionnaire via a shared link. All students included, voluntarily participated in this cross-sectional study by completing the adapted COVID-19 knowledge, attitude and practice (KAP) questionnaire. The collected data were analysed to show the level of knowledge, attitude and preventative practices and also to test for significant association between gender and variables for the study. The study was conducted between March 23-April 25, 2021. Results The outcome of the findings showed that students with families with 5-10 members showed significant association with knowledge accuracy on COVID-19 (χ2 = 6.077, p = 0.044). There was a significant association between gender and the need to report the suspected case of COVID-19 infection to the health authorities (χ2 = 14.075, p = 0.001) with more females likely to report a suspected case. More females (59.2%) were significantly (χ2 = 8.904, p = 0.012) involved in the practice of social distancing or home quarantine as a preventive measure. Conclusions This study showed evidence of high prevalence of knowledge related to COVID-19 in majority of the study participants. This is a pointer to the efficacy and success of present public health campaigns in Nigeria.
