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).

On 6 February at 4:17 am, a 7.8 degrees magnitude earthquake struck southern Turkey near Syria’s
northern border. The US Geological Survey said the earthquake was centered about 33 km (20 miles)
from Gaziantep, a major city and provincial capital. Tremors were felt as far away as Lebanon, Greece...,
Palestine, and the island of Cyprus. Another big earthquake was felt on the same day at around 1:24
pm local time, largely in the same affected areas. Aftershocks will continue to shake the area as fault
lines adjust to such a huge initial tremor. There’s even a risk—albeit a small one—of an aftershock
bigger than the original quake.

Chagas is a complex, multidimensional phenomenon in which political, economic, environmental, biomedical, epidemiological, psychological, and sociocultural factors intersect. Nonetheless, the hegemonic conceptualisation has long envisioned Chagas as primarily a biomedical question, while ignoring or... downplaying the other dimensions, and this limited view has reinforced the disease’s long neglect. Integrating the multiple dimensions of the problem into a coherent approach adapted to field realities and needs represents an immense challenge, but the payoff is more effective and sustainable experiences, with higher social awareness, increased case detection and follow-up, improved adherence to care, and integrated participation of various actors from multiple action levels. Information, Education, and Communication (IEC) initiatives have great potential for impact in the implementation of multidimensional programs of prevention and control successfully customised to the diverse and complex contexts where Chagas disease persists.

Trachoma, caused by particular serovars of Chlamydia trachomatis, is the leading
infectious cause of blindness. Infection is transmitted within ocular and nasal secretions that are passed from person to person on fingers, fomites (such as clothing) and eye-seeking flies (particularly Musca sorbens)....
Ophthalmic infection is associated with an inflammatory conjunctivitis known as “active trachoma”. Repeated episodes of active trachoma can scar the eyelids. In some individuals this leads to trachomatous trichiasis (TT), in which one or more eyelashes on the upper
eyelid touch the eye. TT is extremely painful. It can be corrected surgically, but, if left untreated, may lead to corneal opacification, resulting in vision impairment and blindness.

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

This new guidance aims to support programme implementers, coordinators and others in humanitarian settings in their actions to counter suicide and self-harm in humanitarian contexts and to save lives.
This Trachoma Action Planning – a planning guide – is published by the
International Coalition for Trachoma Control at the request of the
World Health Organization Alliance for the Global Elimination of Trachoma
by 2020.
The infectious disease burden in India is among the highest in the world. A large amount of antibiot-ics are consumed in fighting infections, some of them saving lives, but every use adding to antibiotic resistance in bacteria. Antibiotic use is increasing steadily (table 1), particularly ... certain antibiotic classes (beta-lactam antibacterials), most notably in the more prosperous states. Resistance follows in lock-step.

Schools are generally the most popular setting for drug-use-
prevention programmes, and are used both by governmental and
non-governmental agencies. This may be for many reasons: ease of
obtaining funding for school drug-use-prevention programmes, the
captive audience, and the popular perception... that drug prevention
should start from schools, or the need to show that action is being
taken to control a serious social problem.

The coronavirus disease 2019 (COVID-19) pandemic has created a global and gendered crisis that is compounding existing inequalities and disproportionately affecting girls and women. Emerging evidence from the COVID-19 crisis in 2020 shows school closures, disruptions in essential services and rising... poverty contributed to girls’ increased risk of female genital mutilation (FGM). School closures limited the monitoring and reporting of cases of FGM. Rising household monetary poverty may have contributed to families adopting negative coping mechanisms, including having girls undergo FGM as a precursor to marriage to reduce household costs. A report from the United Nations Population Fund (UNFPA) estimates 2 million additional cases of FGM by 2030 due to the pandemic.
