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.

Reducing the humanitarian impact of the use of explosive weapons in populated areas is a key priority for the United
Nations, the International Committee of the Red Cross (ICRC), civil society and an increasing number of Member States.
The United Nations Secretary-General has expressly called on... parties to conflict to avoid the use in populated areas of
explosive weapons with wide-area effects.
While the use of explosive weapons in populated areas may in some circumstances be lawful under international
humanitarian law (IHL), empirical evidence reveals a foreseeable and often widespread pattern of harm to civilians,
particularly from explosive weapons with wide-area effects.
Many types of explosive weapons exist and are currently in use. These include air-delivered bombs, artillery projectiles,
missiles and rockets, mortar bombs, and improvised explosive devices (IEDs). Some are launched from the air and
others are surface launched. Whilst different technical features dictate their accuracy of delivery and explosive effect,
these weapons generally create a zone of blast and fragmentation with the potential to kill, injure or damage anyone
or anything within that zone. This makes their use in populated areas – such as towns, cities, markets and camps for
refugees and displaced persons or other concentrations of civilians – particularly problematic. The problems increase
further if the effects of the weapon extend across a wide-area either because of the scale of blast that they produce; their
inaccuracy; the use of multiple munitions across an area; or a combination thereof.

This scoping study done in Myanmar offers the chance for FoodSTART+ to explore prospects for future partnerships in another important country of the region. The study was done from October 2016 to February 2017 and included visits to selected major potato and cassava production areas to meet with re...spective stakeholders and market actors.
Although root and tuber crop (RTC) production in Myanmar has gradually increased since the late 1990s, they still lag behind the other major crops like rice. No RTCs are included in the country’s list of primary important crops even though potatoes are regularly consumed in daily meals while other common RTCs like cassava, elephant foot yam and sweetpotato are consumed occasionally. RTCs primarily contribute to food security and livelihoods through the income generated from their sale, whether fresh or processed, rather than directly through consumption.

A 7.2-magnitude earthquake struck southwestern Haiti at 8:30am local time at a depth of around 10km. The epicentre was recorded around 12km northeast of SaintLouis-du-Sud, about 125km west of the capital Port-au-Prince.
● In the aftermath of the devastating 7.2-magnitude earthquake that hit Hai...ti on 14 August, authorities report more than 2,200 people dead, at least 344 missing, over 12,000 injured and upwards of 130,000 homes damaged or destroyed.

Scaling Up Multi-Sectoral Efforts to Establish a Strong Nutrition Foundation for Uganda’s Development
As part of a wider organisational undertaking to better capture and communicate the effectiveness of its work, Oxfam developed an evaluative method to assess the quality of targeted humanitarian responses. This method uses a global humanitarian indicator tool which is intended to enable Oxfam GB to ...estimate how many disaster-affected men and women globally have received humanitarian aid that meets establishes standards for excellence. This method was used after the independence of South Sudan, which was followed by political tensions with its neighbour on issues unresolved from the Comprehensive Peace Agreement (CPA) which include border demarcation, wealth-sharing and the fate of the disputed territory of Abyei.

Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.
