Pressure cooker ownership and food security in Aurangabad, India
Objective: To explore associations between household food security and home
gardening, use of soya and pressure cooker ownership in low-income households
affected by HIV/AIDS in Aurangabad, India.
Design: Cross-sectional pilot study which assessed household food security using
the validated US Department of Agriculture’s food security core-module questionnaire.
Questions were added to explore household environment, education,
occupation, home gardening, use of soya and pressure cooker ownership.
Households with very low v. low food security were compared using logistic
regression analysis, controlling for confounding by socio-economic status.
Setting: Aurangabad is an urban setting situated in a primarily agricultural
dependent area. The study was carried out in 2008, at the peak of the global food crisis.
Subjects: Adult caregivers of children affiliated with the Network of People Living
with HIV/AIDS in Aurangabad.
Results: All except for one of 133 households were identified as food insecure
(99?2 %). Of these households, 35?6% had to cut size or skip a meal in the past
30 d. Households that cut meal size due to cooking fuel shortages were more
likely to have very low food security (OR54?67; 95% CI 1?62, 13?44) compared
with households having no cooking fuel shortages. Owning a pressure cooker
was shown to be protective against very low food security after controlling for
confounding by socio-economic status (OR50?27; 95% CI 0?11, 0?64).
Conclusions: Only pressure cooker ownership showed a protective association
with low household food security. Pressure cookers save household fuel costs.
Therefore, future interventions should explore pressure cookers as a sustainable
means of improving household food securit
Disclosure of human immunodeficiency virus status to children in South Africa : a comprehensive analysis
CITATION: Van Elsland, S. L., et. al. 2019. Disclosure of human immunodeficiency virus status to children in South Africa : a comprehensive analysis. Southern African Journal of HIV Medicine, (20(1):a884, doi:10.4102/sajhivmed.v20i1.884.The original publication is available at http://www.sajhivmed.org.za/Background: The extent of disclosure of HIV status to children and adolescents and the context
facilitating their disclosure process have received little attention.
Objectives: To assess disclosure and provide a comprehensive analysis of characteristics
associated with disclosure to children (3–14 years) receiving antiretroviral treatment in a South
African semi-urban clinic.
Methods: This cross-sectional study used structured interview administered questionnaires
which were supplemented with medical record data. Predictors included child, caregiver,
clinical and socio-economic characteristics, viral suppression, immune response, adherence,
health-related quality of life and family functioning.
Results: We included 190 children of whom 45 (23.7%) received disclosure about their HIV
status, of whom 28 (14.7%) were partially disclosed and 17 (8.9%) were fully disclosed. Older
age of the child and higher education of the caregiver were strongly associated with disclosure.
Female caregivers, detectable viral load, syrup formulation, protease inhibitor (PI) regimens
with stavudine and didanosine, and self-reported non-adherence were strongly associated
with non-disclosure.
Conclusion: When children do well on treatment, caregivers feel less stringent need to disclose.
Well-functioning families, higher educated caregivers and better socio-economic status
enabled and promoted disclosure. Non-disclosure can indicate a sub-optimal social structure
which could negatively affect adherence and viral suppression. There is an urgent need to
address disclosure thoughtfully and proactively in the long-term disease management. For the
disclosure process to be beneficial, an enabling supportive context is important, which will
provide a great opportunity for future interventions.https://sajhivmed.org.za/index.php/hivmed/article/view/884Publisher's versio
Age groups that sustain resurging COVID-19 epidemics in the United States
After initial declines, in mid-2020 a resurgence in transmission of novel coronavirus disease (COVID-19) occurred in the United States and Europe. As efforts to control COVID-19 disease are reintensified, understanding the age demographics driving transmission and how these affect the loosening of interventions is crucial. We analyze aggregated, age-specific mobility trends from more than 10 million individuals in the United States and link these mechanistically to age-specific COVID-19 mortality data. We estimate that as of October 2020, individuals aged 20 to 49 are the only age groups sustaining resurgent SARS-CoV-2 transmission with reproduction numbers well above one and that at least 65 of 100 COVID-19 infections originate from individuals aged 20 to 49 in the United States. Targeting interventions-including transmission-blocking vaccines-to adults aged 20 to 49 is an important consideration in halting resurgent epidemics and preventing COVID-19-attributable deaths

Evidence of initial success for China exiting COVID-19 social distancing policy after achieving containment.
Background: The COVID-19 epidemic was declared a Global Pandemic by WHO on 11 March 2020. By 24 March 2020, over 440,000 cases and almost 20,000 deaths had been reported worldwide. In response to the fast-growing epidemic, which began in the Chinese city of Wuhan, Hubei, China imposed strict social distancing in Wuhan on 23 January 2020 followed closely by similar measures in other provinces. These interventions have impacted economic productivity in China, and the ability of the Chinese economy to resume without restarting the epidemic was not clear. Methods: Using daily reported cases from mainland China and Hong Kong SAR, we estimated transmissibility over time and compared it to daily within-city movement, as a proxy for economic activity. Results: Initially, within-city movement and transmission were very strongly correlated in the five mainland provinces most affected by the epidemic and Beijing. However, that correlation decreased rapidly after the initial sharp fall in transmissibility. In general, towards the end of the study period, the correlation was no longer apparent, despite substantial increases in within-city movement. A similar analysis for Hong Kong shows that intermediate levels of local activity were maintained while avoiding a large outbreak. At the very end of the study period, when China began to experience the re-introduction of a small number of cases from Europe and the United States, there is an apparent up-tick in transmission. Conclusions: Although these results do not preclude future substantial increases in incidence, they suggest that after very intense social distancing (which resulted in containment), China successfully exited its lockdown to some degree. Elsewhere, movement data are being used as proxies for economic activity to assess the impact of interventions. The results presented here illustrate how the eventual decorrelation between transmission and movement is likely a key feature of successful COVID-19 exit strategies
Potential impact of the COVID-19 pandemic on HIV, tuberculosis, and malaria in low-income and middle-income countries: a modelling study
Background: COVID-19 has the potential to cause substantial disruptions to health services, due to cases overburdening the health system or response measures limiting usual programmatic activities. We aimed to quantify the extent to which disruptions to services for HIV, tuberculosis, and malaria in low-income and middle-income countries with high burdens of these diseases could lead to additional loss of life over the next 5 years. Methods: Assuming a basic reproduction number of 3·0, we constructed four scenarios for possible responses to the COVID-19 pandemic: no action, mitigation for 6 months, suppression for 2 months, or suppression for 1 year. We used established transmission models of HIV, tuberculosis, and malaria to estimate the additional impact on health that could be caused in selected settings, either due to COVID-19 interventions limiting activities, or due to the high demand on the health system due to the COVID-19 pandemic. Findings: In high-burden settings, deaths due to HIV, tuberculosis, and malaria over 5 years could increase by up to 10%, 20%, and 36%, respectively, compared with if there was no COVID-19 pandemic. The greatest impact on HIV was estimated to be from interruption to antiretroviral therapy, which could occur during a period of high health system demand. For tuberculosis, the greatest impact would be from reductions in timely diagnosis and treatment of new cases, which could result from any prolonged period of COVID-19 suppression interventions. The greatest impact on malaria burden could be as a result of interruption of planned net campaigns. These disruptions could lead to a loss of life-years over 5 years that is of the same order of magnitude as the direct impact from COVID-19 in places with a high burden of malaria and large HIV and tuberculosis epidemics. Interpretation: Maintaining the most critical prevention activities and health-care services for HIV, tuberculosis, and malaria could substantially reduce the overall impact of the COVID-19 pandemic.

Database of epidemic trends and control measures during the first wave of COVID-19 in mainland China.
OBJECTIVES: In this data collation study, we aimed to provide a comprehensive database describing the epidemic trends and responses during the first wave of coronavirus disease 2019 (COVID-19) throughout the main provinces in China. METHODS: From mid-January to March 2020, we extracted publicly available data regarding the spread and control of COVID-19 from 31 provincial health authorities and major media outlets in mainland China. Based on these data, we conducted descriptive analyses of the epidemic in the six most-affected provinces. RESULTS: School closures, travel restrictions, community-level lockdown, and contact tracing were introduced concurrently around late January but subsequent epidemic trends differed among provinces. Compared with Hubei, the other five most-affected provinces reported a lower crude case fatality ratio and proportion of critical and severe hospitalised cases. From March 2020, as the local transmission of COVID-19 declined, switching the focus of measures to the testing and quarantine of inbound travellers may have helped to sustain the control of the epidemic. CONCLUSIONS: Aggregated indicators of case notifications and severity distributions are essential for monitoring an epidemic. A publicly available database containing these indicators and information regarding control measures is a useful resource for further research and policy planning in response to the COVID-19 epidemic
Paediatric ART Adherence in South Africa: A Comprehensive Analysis
Adherence to antiretroviral therapy (ART) remains a challenge for HIV-infected children. In this cross-sectional study, we used structured interview-administered questionnaires and medical records to measure adherence levels and factors associated with adherence and viral suppression. We included 195 South African children aged 2.1–12.9 on ART. Adherence levels ranged between 20.5% (pill count) and 89.1% (self-report). Boys were less adherent according to self-report, girls were less adherent according to pill count. Caregivers ensured medication was taken when the condition directly affected daily life. Well-functioning families and families with high SES provide a context supportive of adherence. Non-disclosure and difficulties administering medication negatively affected adherence and viral suppression. This study shows challenging levels of adherence impacting directly on viral suppression in a South African paediatric HIV program. Gender roles, non-disclosure and difficulty administering medication may undermine adherence and should be taken into account for clinical guidelines, policy design and inform strategies
