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).

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

This guidance document has been produced by WHO to assist blood services in the development of national plans to respond to any emerging infectious threats to the sufficiency or safety of the blood supply, whether from an existing infectious agent that is changing in incidence and spread, or from a ...newly identified infectious agent. It is intended that this document be followed to guide the national blood service through the process of planning how to respond in a timely, controlled and appropriate way to any specific infectious threat that may subsequently emerge. It is acknowledged that it is not only the blood supply that may be affected by such emerging infectious threats; in those countries undertaking transplantation, the supply of cell, tissues and organs may also be threatened. Increasingly, blood services are taking overall national responsibility for transplantation in their capacity as the organization responsible for the collection, processing, storage and supply of cells, tissues and organs. This approach is both sensible and appropriate, as the overall donor selection and screening processes are the same or very similar. This guidance document can therefore also be used to assist those bodies responsible for the provision of cells, tissues and organs to prepare for an emerging infectious threat.

A very large number of people from Ukraine are fleeing the country and entering the European Union (EU) countries bordering Ukraine (Hungary, Poland, Romania, Slovakia) and the EU-neighbourhood country of the Republic of Moldova. Those fleeing Ukraine - mainly women and children - are ...currently dispersing into communities, but as more people congregate at border crossings it is likely that they will also need to be housed in reception centres.

The five hepatitis viruses have different epidemiological profiles, and their impact, duration, and transmission route also vary. The most common transmission routes contributing to the spread of hepatitis are exposure to infected blood via blood transfusion or unsafe injection practices, consumptio...n of contaminated food and drinking water, and transmission from mother to child during pregnancy and delivery. Also, unsafe injection practices, including the use of unsterile needles and syringes, serve as a major pathway for the spread of hepatitis B and C, and reducing transmission of both diseases requires addressing these practices.

The Regional Action Framework for Noncommunicable Disease Prevention and Control provides a unified vision of objectives and recommended actions to combat the noncommunicable disease (NCD) epidemic in the Western Pacific Region. Implementation should be supported by cross-sectoral coordination..., sustainable financing, evidence-based policy, and community engagement, tailored to each Member State’s unique context. In doing so, Member States are encouraged to transform a disease treatment-centered “sick system” into a “health system” in which a population’s health and well-being enable socioeconomic development.

Severe cases of COVID-19 are associated with rehabilitation needs related to the consequences of ventilatory support, and prolonged immobilization and bed rest. These may include: − Impaired lung function; − Physical deconditioning and muscle weakness; − Delirium and other cognitive impairment...s; − Impaired swallow and communication; and − Mental health disorders and psychosocial support needs. − Rehabilitation needs may be amplified by underlying health conditions and decrements in health associated with ageing, − Rehabilitation professionals play an important role in facilitating early discharge, which is especially critical in the context of hospital bed shortages. − Rehabilitation needs of people with severe COVID-19 exist during the acute, sub-acute and long-term phases of care; rehabilitation professionals should be positioned in ICUs, hospital wards, stepdown facilities and in the community. − Particularly in the acute phase, rehabilitation interventions for patients with severe COVID-19 requiring ventilatory support generally require a particular skill-set acquired through specialist training.

Introduction The novel Coronavirus (nCoV) epidemic in 2019 -2020 has recently emerged. The route of transmission is not totally known, although it is known that it can spread from person to person, and local health care systems may be ill-equipped to handle a large-scale outbreak. Furthermore, misco...nceptions and misinformation about the disease often spreads rapidly in such epidemics.
In previous epidemics mental health and psychosocial support (MHPSS) has been identified as a key priority. MHPSS ensures the well-being of the affected populations, and counter-acts the threats to public health and safety that fear, stigmatization and misconception pose. Access to information, knowledge about the disease and how it spreads, make it easier for the affected to feel supported and calm, and to comply with instructions. Furthermore, psychosocial support to staff and volunteers help the operation as work conditions are extremely stressful.
This briefing note provides background knowledge on the MHPSS aspects related to nCoV and suggests MHPSS activities that can be implemented. The messages can be helpful for those in contact with patients or relatives and feel the strain of working and living during the epidemic. The briefing is aimed both at those working in any capacity with those affected by nCoV and for the MHPSS responders who implement MHPSS activities and interventions for everyone affected.

ABSTRACT
Objectives: We developed COVID-19 Outbreak Simulator (https://ictr.github.io/covid19-outbreak-simulator/) to quantitatively estimate the effectiveness of preventative and interventive measures to prevent and battle COVID-19 outbreaks for specific populations.
Recognizing the extent to which the COVID-19 outbreaks affects women and men differently is hugely important. Some preliminary data suggested that more men than women are dying, potentially due to sex-based immunological differences, higher rates of cardiovascular disease for men and lifestyle choic...es, such as smoking. However, the experiences and lessons learned from the Zika and Ebola outbreaks and the HIV pandemic demonstrate that robust gender analysis and informed, gender-integrated response are vital to strengthen the access and acceptability of the humanitarian services needed to meet the distinct needs of women and girls, as well as men and boy and LGBTI people.
