Pandemic modelling for regions implementing an elimination strategy.

During the COVID-19 pandemic, some countries, such as Australia, China, Iceland, New Zealand, Thailand, and Vietnam successfully implemented an elimination strategy, enacting strict border control and periods of lockdowns to end community transmission. Atlantic Canada and Canada's territories implemented similar policies, and reported long periods with no community cases. In Newfoundland and Labrador (NL), Nova Scotia, and Prince Edward Island a median of 80% or more of daily reported cases were travel-related from July 1, 2020 to May 31, 2021. With increasing vaccination coverage, it may be appropriate to exit an elimination strategy, but most existing epidemiological frameworks are applicable only to situations where most cases occur in the community, and are not appropriate for regions that have implemented an elimination strategy. To inform the pandemic response in regions that are implementing an elimination strategy, we extend importation modelling to consider post-arrival travel restrictions, and pharmaceutical and non-pharmaceutical interventions in the local community. We find that shortly after the Omicron variant had begun spreading in Canada, the expected daily number of spillovers, infections spread to NL community members from travellers and their close contacts, was higher than any time previously in the pandemic. By December 24, 2021, the expected number of spillovers was 44% higher than the previous high, which occurred in late July 2021 shortly after travel restrictions were first relaxed. We develop a method to assess the characteristics of potential future community outbreaks in regions that are implementing an elimination strategy. We apply this method to predict the effect of variant and vaccination coverage on the size of hypothetical community outbreaks in Mount Pearl, a suburb of the St. John's metropolitan area in NL. Our methodology can be used to evaluate alternative plans to relax public health restrictions when vaccine coverage is high in regions that have implemented an elimination strategy.

Challenges and coping strategies among distance education learners: Implication for human resources managers.

This study examined challenges and coping strategies among distance education learners and their implications for human resources managers. The quantitative and descriptive survey design was adopted, and a sample of 1358 university students pursuing distance programmes was drawn from a study population of 44,458 distance undergraduate and postgraduate students. The data collection instrument was a questionnaire, and the data obtained was analysed with Partial Least Square Structural Equation Modelling (PLS-SEM). The study found that instructional challenges, psychlogical challenges, socio-religious challenges and institutional challenges had a statistically significant relationship with coping strategies and educational output among distance learners. Coping strategies also obtained a statistically significant relationship with educational output. The four main effective coping strategies identified among distance learners were problem-focused, emotion-focused, preventive and proactive coping strategies. It was recommended that human resource managers provide orientation, counselling on coping strategies, decent and suitable teaching and learning facilities, supply modules and communicate assessment feedback on time, and provide competent and committed course tutors to help reduce challenges faced by distance learners.

Factors influencing the practice of exclusive breastfeeding among nursing mothers in a peri-urban district of Ghana.

BACKGROUND: Exclusive breastfeeding (EBF) is one of the optimal infant and young child feeding practices. Globally, <40% of infants under 6 months of age are exclusively breastfed. In Ghana, 63% of children <6 months are exclusively breastfed which is far less than the 100% recommended by the United Nation Children Emergency Fund. This study was carried out to find out the factors that influence the practice of exclusive breastfeeding in the district. METHODS: A cross-sectional quantitative study was conducted using structured questionnaires. A convenience sampling technique was employed to select 380 nursing mothers who attended postnatal care at the postnatal clinic in all the 13 health facilities with child welfare clinics (both public and private) and were available on the day of data collection. Data were analysed using frequency and CHISQ tables. RESULTS: There was a significant association between socio-demographic characteristics of mothers such as age (p = 0.129), religion (p = 0.035) type of employment (p = 0.005) and the practice of exclusive breastfeeding. Again, there was significant relationship between mothers' knowledge on EBF in terms of sources of information about EBF (p = 0.000), steps taken by mothers who perceived not to have breast milk (p = 0.000), some medical conditions of nursing mothers (p = 0.000) and the practice of EBF. CONCLUSION: Most nursing mothers use infant formula feeds as either supplement or substitute for breast milk based on their perception that breast milk may not be sufficient for the babies despite the high cost of these artificial milk. This puts the babies at a higher risk of compromised health and malnutrition which has the potential of increasing infant mortality. Most mothers are not practicing exclusive breastfeeding because their spouses and family members do not allow them.
