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.

Child Friendly Spaces (CFSs) are used by humanitarian agencies as a means to promote protection and psychosocial wellbeing for children in emergency settings. World Vision International together with Columbia University is conducting a series of studies to investigate the effectiveness of CFSs in va...rious humanitarian contexts in order to document evidence of the positive effects they have in relation to child wellbeing and protection, to identify good practice in their design and implementation and to develop improved monitoring and evaluation approaches for CFSs. The case studies have so far all been focused on refugee settings and while internally displaced populations (IDPs) share many of the circumstances and challenges of refugees it was decided that CFSs operating in IDP settings warrant a particular investigation in order to assess their relevance and effectiveness in promoting child protection and psychosocial wellbeing. This report thus presents the findings from an IDP focused study on CFS effectiveness in three camps near Goma, eastern Democratic Republic of Congo (DRC).

COVID-19 has turned the world upside down. Everything has been impacted. How we live and interact with each other, how we work and communicate, how we move around and travel. Every aspect of our lives has been affected.
In 2005, the World Health Organization (WHO) Member States adopted the revised International
Health Regulations (IHR) (2005). The Regulations provide a unique public health framework in the
form of obligations and recommendations that enable countries to better p...revent, prepare for and
respond to public health events and emergencies of potential international concern, including chemical events.

Leptospirosis is an infectious disease caused by pathogenic organisms belonging to the genus Leptospira, that are transmitted directly or indirectly from animals to humans. Leptospirosis is a major direct zoonosis. Humanto-human transmission occurs only very rarely.
ON LIFE SUPPORT3The Democratic Republic of Congo’s Ebola outbreak has been contained, but confl ict and under-development leave over three million children at risk from measles and other killer diseases. The country’s medical services – ill-equipped and under-resourced – are on life support ...and in no condition to protect children unless urgent measures are taken.

The 2019 edition treating data for 2018 marks sustained international efforts dedicated to reporting on, analysing and understanding the year-to-year variations and long-term trends of a changing climate.
Barriers to the prompt and effective diagnosis and treatment of malaria exist at both the community and health facility level. Household surveys measure malaria case management at the population level with standard indicators that assess treatment-seeking behavior, access to diagnostic testing, and ...access to appropriate treatment. Performance on these indicators varies widely from country to country. Among countries with Demographic and Health Surveys (DHS) or Malaria Indicator Surveys (MIS) completed between 2014 and 2016, advice and treatment was sought for a median of 47% of children under age 5 with fever.

Urogenital schistosomiasis is a common neglected tropical disease in many rural communities in African countries, with patches of infection in the Eastern Mediterranean Region. Globally, an estimated 239 million people are currently infected, with burden estimated at more than 3.5 million disability...-adjusted life years (DALYs). In many endemic areas, severely infected individuals may suffer fibrosis of the bladder, kidney damage, bladder cancer, and death if untreated. This, however, depends on several factors such as host-parasite genetics, degree and length of exposure, intensity of infection, host immune response to the parasites, and coinfections with other tropical diseases such as malaria and HIV-1.

Disabled people in developing countries are the poorest of the poor: if we are serious about tackling extreme poverty, our development work has to target them. The post-2015 development framework offers hope that disabled people will finally get the prominence they deserve on the global development ...agenda. But this will only be possible with sustained political pressure, and the UK’s position will only be credible if it leads by example in its own development work. Disabled people experience some of the most extreme poverty in the world, but there are also realistic opportunities for donors to turn the situation around.
