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.

Sudan recorded the first COVID-19 case on 13 March 2020 and, at the beginning of July, the Federal Ministry of Health had confirmed that nearly 10,000 people had contracted the virus, including over 600 who died from the disease across the country. Although more than 70 per cent of the confirmed cas...es are in the Khartoum area, COVID-19 has spread throughout the country, with the highest numbers recorded in the central and eastern states. With extremely low testing capacity — around 800 samples per day, the lowest in the region — the official figures of confirmed cases likely underestimate the extent of the pandemic and the actual situation is unknown.

Infectious diseases are constantly in transition. New diseases develop, known dis-eases become widespread or reemerge, and occasionally a disease is eradicated.Infectious diseases such as HIV, tuberculosis, and cholera are significant causes ofillness and death in many parts of the world. Health car...e personnel are on thefront lines, helping to protect their clients from infectious diseases and treatingthem when infections occur. During the course of their work, health care person-nel perform clinical procedures or other activities that can expose both them andtheir clients to potentially infectious microorganisms. Many of their clients aresick and thus may be more susceptible to infections or may have infections thatcan be transmitted to others. Fortunately, all staff working at health care facilities can perform simple proce-dures to minimize risk—to themselves and clients—and reduce the spread ofinfections. These practices can be integrated at minimal cost into the routineworkday at clinics and hospitals around the world. This reference booklet isspecifically designed for use at all levels of the health care system, from thelargest hospitals to the smallest dispensaries or health posts, in settings whereresources are scarce. This booklet, which was first published in 1999, has now been updated. Whilemost practices remain the same, there have been a few important changes—forexample, in recommendations related to hand hygiene and standard precautions.Nonetheless, this booklet continues to present practical recommendations forsimple and relatively low-cost procedures that can be implemented anywhere,with basic supplies and little to no high-technology equipment.

Risk Communication and Community Engagement (RCCE) is an essential part of any disease outbreak response. Risk communication in the context of an Ebola outbreak refers to real time exchange of information, opinion and advice between frontline responders and people who are faced with the threat of Eb...ola to their survival, health, economic or social wellbeing. Community engagement refers to mutual partnership between Ebola response teams and individuals or communities in affected areas, whereby community stakeholders have ownership in controlling the spread of the outbreak.
It is intended to be used to guide RCCE work which is central to stopping the outbreak and preventing its further amplification. Unlike other areas of response, RCCE draws heavily on volunteers, frontline personnel and on people without prior training in this area. As such, the document provides basic background information, scopes the socio-economic and cultural aspects (that are known at the time of publication), and provides the latest evidence-based advice and approaches

The Ethiopia Cholera Outbreak - Flash Update #8 reports a worsening cholera crisis, with 11,407 cases and 156 deaths as of June 20, 2023. The outbreak, ongoing since August 2022, has spread across 79 districts in Oromia, Somali, SNNP, and Sidama regions, increasing by 85% since May.
Key challenges ...include contaminated water, insecurity, floods, and a global vaccine shortage, leaving 7.7 million people at risk. Only 15% of affected areas have contained the disease. A vaccination campaign has reached 1.9 million people, and 81 Cholera Treatment Centers (CTCs) have been set up, but funding remains critically low.
The United Nations (OCHA) warns that the upcoming rainy season may worsen the outbreak, requiring urgent intervention.

Since the end of 2018, there has been a significant upsurge in violence in Rakhine State after armed conflict broke out between the Arakan Army (AA) and the Myanmar Military. The violence escalated following attacks by the AA against military sites in January 2019 and subsequent counter-attacks by t...he Myanmar Military. The conflict has led to civilian casualties and the destruction of property that has spread to nine townships of Rakhine State (Buthidaung, Kyauktaw, Maungdaw, Minbya, Mrauk-U, Myebon, Pauktaw, Ponnagyun, Rathedaung) and Paletwa Township in neighboring Chin State. Ann and Kyaukphyu townships have been affected at certain points. The conflict has led to a significant displacement of people, some for extended amounts of time and some for short periods, with people fleeing violence subsequently returning to their homes within a few days or weeks. While fighting has occurred largely in rural areas and remote locations, key transport routes and urban and semi-urban areas have also been impacted. Tens of thousands of civilians living in villages have been caught in the middle of intense armed conflict.

The study on health facility preparedness for cholera outbreak response in Cameroon evaluates the ability of healthcare facilities in four cholera-prone districts to manage cholera outbreaks. The findings highlight significant weaknesses, including limited surveillance systems, inadequate access to ...water, poor sanitation, and lack of essential medical supplies such as Oral Rehydration Solution (ORS) and cholera case management guidelines. Many health facilities also lacked trained personnel and proper waste disposal systems, increasing the risk of disease spread within healthcare centers. The study underscores the urgent need for improved hygiene infrastructure, better training, and resource allocation to enhance outbreak response and reduce cholera-related mortality.

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.

The pandemic presents tough choices for governments, local communities, health and school systems, as well as families and businesses: How to re-open safely? How to safeguard people’s lives and protect their livelihoods? Where to allocate scarce resources? How to protect those unable to protect th...emselves? Answers to questions like these will affect our short-term success in battling the spread of the virus and could have impacts for generations to come.
More than ever, the world needs reliable and trustworthy data and statistics to inform these important decisions. The United Nations and all member organizations of the Committee for the Coordination of Statistical Activities (CCSA) collect and make available a wealth of information for assessing the multifaceted impacts of the pandemic. This report updates some of the global and regional trends presented in Volume I and offers a snapshot of how COVID-19 continues to affect the world today across multiple domains.

Recommendations and Summary
This report explores the impact of COVID-19 on humanitarian access in the initial months of the crisis, including both the delivery of assistance and performance of protection activities. It examines the varying crisis responses, including the shift to a more localized a...pproach in certain cases. The analysis draws on case research from Colombia, Myanmar, Nigeria, South Sudan and Yemen, as well as on wide-ranging interviews with humanitarian practitioners and experts from around the world. The research was conducted between August – November 2020. It does not make claims about the legitimacy of government decisions to restrict access – indeed, in many instances, there appeared to be a clear objective of limiting the spread of COVID-19 – but instead focuses on how access limitations have affected the delivery of aid.

In 1998 the Swedish Veterinary Association decided to adopt a general policy for the use of antibiotics in animals. Since then specifi c policies for the use of antibiotics in dogs and cats have been adopted and in 2011 Guidelines for the use of Antibiotics in Production animals – Cattle and Pigs,... were accepted. By decision of the board of the Swedish Veterinary Society (SVS) these guidelines have been updated. Th e over-arching goal of SVS is to achieve a low and controlled use of antibiotics in Swedish animal production so that the fi rst-hand choices of treatment remain effi cient and that the spread of antimicrobial resistance – among animals and herds as well as in the food chain – is kept at a minimum. Keeping antimicrobial resistance in animals low is important also for human health, since we are all part of the same ecosystem. Th e authors of these guidelines hope that they may be useful for veteri-narians in clinical practice when deciding on treatments for common diseases and ailments caused by bacteria. Sometimes the decision may even be to refrain from use of antibiotics and chose other ways of improving herd health.

Antimicrobial resistance (AMR) is one of the top 10 global public health threats facing humanity. AMR threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses and fungi.
It occurs when microorganisms develop resistance to me...dicines that are relied upon for treatment, making some conditions difficult or impossible to cure. As a result, infections persist in the body, increasing the risk of disease spread, severe illness and death.
The Antimicrobial Resistance channel offers learning resources to support implementation of the Global Action Plan on AMR (2015), by building health care worker competencies to help combat AMR in their daily clinical practice.
