Since 2001, several Demographic and Health Surveys (DHS) include HIV
testing. For many countries, in particular in sub-Saharan Africa, DHS are
the only national source of data in general population. Several DHS collect
latitude and longitude of surveyed clusters but the sampling method is not
ap...propriate to derive local estimates: sample size is not large enough for a
direct spatial interpolation.
We developed a generic approach to map spatial regional trends of HIV
prevalence from DHS. We present how our results from Burkina Faso 2003
DHS shed new light on HIV epidemics.

The guidelines acknowledge that overcrowding, unhygienic conditions and high inmate turn over contribute to the spread of infectious diseases within correctional facilities. The document states that voluntary HIV counselling and testing must be offered to all inmates when they enter facilities, duri...ng their incarceration at an inmate’s request and upon their release. All inmates must be screened for TB symptoms upon entry to facilities and at least bi-annually thereafter as well as upon release. Universal screening for anal, oral and genital STIs must be done at entry and upon self-presentation

Since the emergence of COVID 19 in December 2019, various public health responses measures have been implemented to control the pandemic. Among measures taken by the Africa CDC was the launch of PACT initiative to accelerate COVID 19 testing. Key to the initiative is the engagement of Community Heal...th Workers (CHWs) in risk communication and community engagement (RCCE), surveillance activities for early case identification, contacts tracing and in facilitating referrals for testing and continuum of care.
As of 31 May 2021, Through PACT support, over 17154 CHWs have been trained and locally deployed in 24 AU Member states. The PACT supported CHWs visited more than 2,568,654 households for community engagement activities, active case search and contact tracing, identified 1,618,601 Contacts, 710,167 COVID 19 suspect cases based on the standard case definition and facilitated referrals for 553053 (78%) suspect cases for testing. These efforts were crucial for early identification and isolation of cases in limiting further transmission.

SARS-CoV-2 infections among children and adolescents cause less severe illness and fewer deaths compared to adults. While a less severe course of infection is a positive outcome, there are concerns that mild symptoms may have led to less testing, resulting in fewer identified cases of COVID-19 in ch...ildren. If children with mild or no symptoms transmit the disease, they may act as drivers of transmission within their communities. Understanding symptoms, infectivity and patterns of SARS-CoV-2 transmission in children and adolescents is essential for developing, adapting and improving control measures for COVID-19 across all ages. This is a summary of the current knowledge around SARS-CoV-2 infection acquisition and transmission and COVID-19 disease symptoms in children and adolescents. It aims to inform decisions, based on local contexts, on how to best keep schools, kindergarten and day-care facilities open and what advice to apply to intergenerational mixing.

EU/EEA Member States and the UK have increased their laboratory capacity tremendously over the past 11 months as the majority of the Member States reported sufficient testing capacity until March 2021.
Many countries are adding rapid antigen detection tests (RADT) to their ...testing strategies in order to reduce pressure on RT-PCR testing.
Some Member States have already included RADT in their case definition.
The main bottlenecks, such as shortages of laboratory consumables and human resources, as well as sample storing facilities, continue to exist and may affect the overall laboratory response to COVID-19.

The report finds that, as of 3 November, in 87 countries with age-disaggregated data, children and adolescents under 20 years of age accounted for 1 in 9 of COVID-19 infections, or 11 per cent of the 25.7 million infections reported by these countries. More reliable, age-disaggregated data on infect...ion, deaths and testing is needed to better understand how the crisis impacts the most vulnerable children and guide the response

Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The diagnosis of asthma in young children is limited by the inability to perform objective lung function testing in this group of patients and the wi...de variety of conditions that can phenotypically present with asthma-like symptoms.
This article provides an evidence-based approach for clinicians to accurately diagnose asthma in young children and to assess the level of control to guide therapeutic decisions.
The South African Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The asthma diagnosis and control task groups reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system, providing recommendations based on current evidence.

Language influences the way we think, how we perceive reality, and how we behave. With respect to HIV, language can embody stigma and discrimination, which impacts access to testing, acquisition of HIV, and engagement with treatment. Language plays a role in supporting respect and empowerment of ind...ividuals, as communities shape how they are referred to and the labels they wish to use. Consideration and use of appropriate language can strengthen the global response to the HIV pandemic by diminishing stigma and discrimination and increasing support and understanding for individuals and communities living with HIV.

The number of confirmed COVID-19 cases detected and reported in each country is influenced by
many factors including limited access and/or utilization of healthcare and COVID-19 testing, limited
surveillance, lack of knowledge amongst the population about when to seek testing, an asymptomatic pres...entation, and other unknown issues. This is true in all countries of the world, and not Africa specific, however there are factors unique to Africa which may also affect the way the virus behaves there. COVID-19 prevalence data are critical for planning effective mitigation strategies and understandingthe true impact of the disease and relevant intervention measures in Africa, which might be quite different from regions with a different population age distribution or risk factor profile.
