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).

March 2022. This report on good practices to combat AMR focuses on activities across human, animal, and environmental health in European countries. The report provides a description of practices, how they were implemented, achievements, and why the practice was unique.
Background: Traumatic stress may arise from various incidents often leading to posttraumatic stress disorder (PTSD). The lifetime prevalence of PTSD is estimated at 1% – 2% in Western Europe, 6% – 9% in North America and at just over 10% in countries exposed to long-term
violence. In South Afri...ca, the lifetime prevalence for PTSD in the general population is estimated at 2.3%.
Aim: To examine the prevalence of posttraumatic stress symptomatology and related psychological functioning in a community sample of adolescents.
Setting: Low-socioeconomic communities in KwaZulu-Natal.

This chapter discusses the antibacterial treatment of leprosy infections. Antibiotic treatment is
a key component of leprosy treatment, as it is vital to prevent the progression of the infection.
Treatment with rifampin and other antibiotics is highly effective and cures 98% of patients with
the ...leprosy infection. Furthermore, the relapse rate is very low, at about 1% over 5–10 years.
There is little M. leprae drug resistance in leprosy and few reports of multi-drug resistance (1, 2, 3,
4, 5, 6, 7, 8). An antibiotic treatment may take months or years to produce clinical improvement,
especially in patients with an initial high bacterial index (BI).

Of the 50 antibiotics in the pipeline, 32 target WHO priority pathogens but the majority have only limited benefits when compared to existing antibiotics. Two of these are active against the multi-drug resistant Gram-negative bacteria, which are spreading rapidly and require urgent solutions.
Gr...am-negative bacteria, such as Klebsiella pneumoniae and Escherichia coli, can cause severe and often deadly infections that pose a particular threat for people with weak or not yet fully developed immune systems, including newborns, ageing populations, people undergoing surgery and cancer treatment.
The report highlights a worrying gap in activity against the highly resistant NDM-1 (New Delhi metallo-beta-lactamase 1), with only three antibiotics in the pipeline. NDM-1 makes bacteria resistant to a broad range of antibiotics, including those from the carbapenem family, which today are the last line of defence against antibiotic-resistant bacterial infections.

In response to the first cases of coronavirus disease 2019 (COVID-19) reported on the continent, many African Union Member States implemented large-scale public health and social measures (PHSM) rapidly. These measures were aimed at reducing transmission and the number of new cases being reported, p...rotecting the most vulnerable populations, and allowing time for countries to ramp up critical healthcare and diagnostic services. While these quick actions bought time for Member States, the negative socio-economic impacts are being felt widely, and countries are now exploring how best to ease these measures back while still managing the outbreak.

Every year, nearly 250 million people move across borders temporarily or permanently for a job opportunity, studying, to flee a crisis back home, or for other reasons. Another 750 million move for similar reasons within the borders of their countries. With the understanding that human mobility affec...ts public health, and health affects human mobility and migrants, for decades, IOM has been providing critical health services to women, children and men on the move, while standing by governments for technical and operational support as needed. In 2019, in lower-income settings and in complex emergencies, along the world’s most perilous migration routes, in the aftermath of natural disasters or in response to disease outbreaks, IOM’s health teams have provided hundreds of thousands with primary health-care consultations, mental health and psychosocial support, sexual and reproductive health care, pre-migration health services, and much more.
This year, more than ever before, as the world reels from the socioeconomic impact of COVID-19, we have experienced that health is a cross-cutting component of overall human development and well-being.

A “catastrophic” combination of drought and communities’ declining resilience has left an estimated 2.3 million people facing severe acute food insecurity – up from an estimate of 1.7 million people a month ago.
Communities across southern Africa have been affected by drought since late 2...018.
This year, large parts of southern and western Zambia received their lowest seasonal rainfall totals since at least 1981, the base year from which normal rainfall is benchmarked. At the same time, northern and eastern parts of the country were affected by flash floods and waterlogging, resulting in poor harvests.

WHO today released its first roadmap to tackle postpartum haemorrhage (PPH) – defined as excessive bleeding after childbirth - which affects millions of women annually and is the world’s leading cause of maternal deaths.
Despite being preventable and treatable, PPH results in around 70 000 de...aths every year. For those who survive, it can cause disabilities and psychological trauma that last for years.
“Severe bleeding in childbirth is one of the most common causes of maternal mortality, yet it is highly preventable and treatable,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “This new roadmap charts a path forward to a world in which more women have a safe birth and a healthy future with their families.”
The Roadmap aims to help countries address stark differences in survival outcomes from PPH, which reflect major inequities in access to essential health services. Over 85% of deaths from PPH happen in sub-Saharan Africa and South Asia. Risk factors include anaemia, placental abnormalities, and other complications in pregnancy such as infections and pre-eclampsia.
Many risk factors can be managed if there is quality antenatal care, including access to ultrasound, alongside effective monitoring in the hours after birth. If bleeding starts, it also needs to be detected and treated extremely quickly. Too often, however, health facilities lack necessary healthcare workers or resources, including lifesaving commodities such as oxytocin, tranexamic acid or blood for transfusions.
“Addressing postpartum haemorrhage needs a multipronged approach focusing on both prevention and response - preventing risk factors and providing immediate access to treatments when needed - alongside broader efforts to strengthen women’s rights,” said Dr Pascale Allotey, WHO Director for Sexual and Reproductive Health and HRP, the UN’s special programme on research development and training in human reproduction. “Every woman, no matter where she lives, should have access to timely, high quality maternity care, with trained health workers, essential equipment and shelves stocked with appropriate and effective commodities – this is crucial for treating postpartum bleeding and reducing maternal deaths.”

Africa is off track to reach the Sustainable Development Goals by 2030 and lags behind in building resilient health systems
and health security, against a backdrop of limited resources. The world envisaged a significant role for governments
in funding the Sustainable Development Agenda, but inadeq...uate funding for health in African countries is
persistent, despite additional continental commitments to address the problem. When commitments to global health
targets and available fiscal space do not align, innovation is warranted.

In where under-five mortality is high and vitamin A deficiency is a public health problem, two high-dose supplements of vitamin A per year, spaced four to six months apart, can strengthen children’s immune systems and improve their chances of survival.
During much of early childhood – from... 6 months to 5years of age – two high doses of vitamin A every year can prevent blindness and hearing loss, boost children’s immunity against diseases like measles and diarrhoea and provide critical protection against death. Like all forms of malnutrition, vitamin A deficiency is a marker of inequality. In countries where diets are lacking in vitamin A and infections and deaths are prevalent, supplementation programmes give vulnerable children a better chance to survive, develop and thrive.

2020 was a year like no other. Amidst on-going humanitarian crises, largely fuelled by conflict and violence but also driven by the effects of climate change – such as the largest locust infestation in a generation – the world had to contend with a global pandemic. In less than one year (March-D...ecember 2020), more than 82 million COVID-19 cases and 1.8 million deaths were recorded. In that timeframe, out of the global COVID-19 totals, 30 per cent of COVID-19 cases and 39 per cent deaths were recorded in GHRP countries.

Weaknesses in care programmes providing anti‐retroviral therapy (ART) persist and are often instigated by late HIV diagnosis and poor linkage to care. We investigated the potential for a home‐based counselling and testin...g (HBCT) campaign to be improved through the optimal timing and enhancement of testing rounds to generate greater health outcomes at minimum cost.
Countries implementing HBCT can reduce costs by optimally timing rounds and generate greater health outcomes through improving linkage, coverage, and retention. Tailoring HBCT campaigns to individual settings can enhance patient outcomes for minimal cost.

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

As the Group of Eight (G8) world leaders meet in Saint Petersburg, Russia for this year’s G8 Summit, it is important to take stock of international efforts to finance the response to the global HIV/AIDS epidemic. Financing a sufficient and sustained response to the epidemic has emerged as one of t...he world’s greatest challenges, and one that will be with us for the foreseeable future. Often, those countries most affected are also least able to respond, increasing their vulnerability to HIV/AIDS and in turn further complicating their ability to address the epidemic, as is the case for many nations in sub-Saharan Africa. In addition, concerns have been raised about “second wave” nations, particularly China, India, and Russia, which stand on the brink of generalized epidemics if more is not done now
