The COVID-19 pandemic has had unprecedented public health, economic, and social impacts on the international community, and prompted an unprecedented range and size of policy actions globally. Collective efforts, at national, regional, and global levels, were called for to contain and mitigate such ...impacts. The public health response measures alone proved to be insufficient, calling for additional socio-economic policy interventions such as ring-fencing economic activities to contain the spread of the virus. Faced with devastating socio-economic costs, all possible sources of financing, both public and private, have been explored.

In the area of nutrition and HIV, children deserve special attention because of their additional needs to ensure growth and development and their dependency on adults for adequate care. It was therefore proposed to first develop guidelines for children and thereafter consider a similar approach for... other specific groups.
The content of these guidelines acknowledges that wasting and undernutrition in HIV-infected children reflect a series of failures within the health system, the home and community and not just a biological process related to virus and host interactions. In trying to protect the nutritional well-being or reverse the undernutrition experienced by infected children, issues of food insecurity, food quantity and quality as well as absorption and digestion of nutrients are considered. Interventions are proposed that are practical and feasible in resource-poor settings and offer a prospect for clinical improvement.
The guidelines do not cover the feeding of infants 0 to 6 months old, because the specialised care in this age group is already addressed in other WHO guidelines and documents.

Esta primeira versão de Medicamentos para prevenção da COVID-19: Orientação dinâmica da OMS aborda o uso de hidroxicloroquina para prevenção da COVID-19. Segue-se a publicação de uma análise sistemática e NMA que reuniu dados de seis estudos com 6.059 participantes que não tinham COVID-...19 e receberam hidroxicloroquina. Três estudos envolveram participantes que tiveram uma exposição conhecida a uma pessoa com infecção por SARS-CoV-2. Em resposta à divulgação dos dados de estudos, o GDG da OMS desenvolveu recomendações sobre a hidroxicloroquina, um agente anti-inflamatório que atua por meio do bloqueio dos receptores Toll-like, reduzindo a ativação das células dendríticas. É usada para tratar a artrite reumatoide e o lúpus eritematoso sistêmico. Tem um efeito antiviral contra muitos vírus in vitro, inclusive o SARS-CoV-2, mas não foi demonstrado um efeito antiviral clinicamente útil para nenhuma infecção viral.

Las infecciones de transmisión sexual (ITS) constituyen un importante problema de salud pública en todo el mundo, que afecta a la calidad de vida y se acompaña de importantes niveles de morbilidad y mortalidad. Estas infecciones influyen directamente en la salud infantil y reproductiva porque tra...en consigo infertilidad, cánceres y complicaciones del embarazo. También tienen una influencia indirecta porque facilitan la transmisión por vía sexual del virus de la inmunodeficiencia humana (VIH), pesando así igualmente en la economía de los países y las personas. Cada día, más de un millón de personas contraen una infección de transmisión sexual. Se calcula que en 2012 hubo en el mundo 357 millones de nuevos casos de ITS curables (blenorragia, clamidiasis, sífilis o tricomoniasis) que afectaron a adultos de entre 15 y 49 años de edad, entre ellos 5,6 millones de casos de sífilis. El número de casos prevalentes de sífilis asciende, según las estimaciones, a unos 18 millones.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

n response to the outbreak, the Africa Centres for Disease Control and Prevention (Africa CDC) has been supporting African Union Member States in responding to the COVID-19 pandemic through a variety of interventions such as non-pharmaceutical interventions, quarantine, testing, isolation, contact t...racing, and clinical management. The Test to Treat guideline aims to increase continental testing efforts and reduce COVID-19 transmission in Africa and put-up response measures to control the impact of the virus, both to limit spread and to reduce substantially the risks of severe health outcomes related to COVID-19 infection. These countermeasures include highly effective vaccines and boosters, rapid testing options for monitoring exposure, and effective therapeutic options for both pre-exposure prevention and treatment of mild-to-moderate disease, oxygen therapy for moderate-severe disease, all of which can potentially be updated efficiently as new variants emerge that may affect the effectiveness of the available tools.

Antimicrobial resistance (AMR) as a serious public health threat was globally acknowledged by WHO in 2015, through the launch of the Global Action Plan (GAP). With a limited number of new antibiotics in the developmental pipeline, many countries are in the process of establishing strategies for anti...microbial stewardship (AMS). Within each country, different healthcare challenges have
contributed to AMR. This has also shaped individual AMS strategies and policies. In South Africa (SA), there is a high burden of infectious diseases, mainly of bacterial origin. In addition, SA also has the highest number of people living with
human immunodeficiency virus (HIV) globally. According to the 2019 statistics, there are approximately 7.97 million people living with HIV in SA. Together with this, SA has the fourth largest tuberculosis population globally.
Other important challenges include poverty, malnutrition, a high burden of non-communicable diseases, and a dire shortage of trained healthcare professionals (e.g. clinicians, pharmacists, and nurses).

La Surveillance épidémiologique est un processus continu de collecte, d'analyse et de diffusion d'informations pour la prise d'actions de riposte. Les activités de surveillance épidémiologique sont mises en oeuvre au Sénégal selon la stratégie SIMR (Surveillance Intégrée de la Maladie et R...iposte) et suivant le RSI (Version 2005). Cependant, très souvent les données de surveillance des maladies, surtout aux niveau communautaire, ne sont pas toujours bien enregistrées, notifiées et analysées.
Aujourd'hui, les maladies transmissibles emergentes et ré-émergentes comme la maldie à Virus Ebola (MVE), constituent une menace importante pour la santé et le bien-êtres de nos communautés. Fort heureusement, les interventions de lutte et de prévention sont bien connues pour certaines.
Il en résulte que des opportunités pour prendre et mettre en place des mesures de riposte appropriées de santé publique pour sauver des vies existens et doivent être clairement indentifiées. Pour cela, il s'avère nécessaire de former de manière adéquate les acteurs communautaires et de mettre en place un système perfomant de surveillance intégrée des maladies aux niveau communautaire soutenu par une communication appropriée avec les populations aussi bien en milieu urbain que rural.

There is paucity of data on the burden and specific drivers operative in the pathogenesis of chronic obstructive pulmonary disease (COPD) in the African setting and populations. Lack of awareness and inadequate knowledge on the aetio-pathogenesis of the disease together with inadequate capacity for ...COPD care contributes to preventive and management challenges. Thus, the majority of patients with COPD are misdiagnosed, misclassified and mismanaged or undertreated. With the struggling improvement in the quality of healthcare in Africa, studies conducted over the last 10 years indicates the rising trends in both the risk factors and the burden of COPD. The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines.
Updated risk rates for hospital admission in patients with non-severe COVID-19
The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19.
The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients.
This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines:
**High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%.
**Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%.
Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk.
Review of COVID-19 treatments for people with non-severe COVID-19
WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022.
If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead.
WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission.
For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol.
WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials.
The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials.
