Liverpool School of Tropical Medicine

The format of this the WHO Guideline on Control and Elimination of Schistosomiasis is just over 60 pages, with 6 Annexes. Collectively, it describes the process and outcome of the many face-to-face and online deliberations of the GDG. This guideline is unlike those before on schistosomiasis which have been based upon expert review alone. Today's guideline takes a less biased approach upon consideration of systematic reviews and more generally appraising published evidence more broadly. In total, there are 6 main recommendations which each following judgments based upon the GRADE criteria as outlined by the following rubric...

Neil D. Young et al., Nature Communications

Conspicuous were expansions in signalling and membrane trafficking proteins, peptidases and their inhibitors as well as gene families linked to immune response regulation, such as a large repertoire of lectin-like molecules. This work provides a sound basis for further studies of snail-parasite interactions in the search for targets to block schistosomiasis transmission.

Soil-Transmitted Helminthiasis

Co-infection of intestinal helminths in humans and animals in the Philippines

Olumayowa T Kajero et al., Transactions of The Royal Society of Tropical Medicine and Hygiene

Associations are likely to exist between STH species in humans and animals, possibly due to shared exposures and transmission routes. Individual factors and behaviours will play a key role in the occurrence of co-infections, which will have effects on disease severity. Moreover, the implications of co-infection for the emergence of zoonoses need to be explored further.

Trachoma

Eye disease trachoma no longer a public health concern in Saudi Arabia, WHO says

Mariam Nihal, The National News (UAE)

The World Health Organisation on Wednesday said trachoma, a neglected eye disease that can cause blindness, was no longer a public health problem in Saudi Arabia. The WHO credited the health ministry's move to integrate a comprehensive eye care programme into the kingdom's primary health care services – the first point of contact in the healthcare system – with helping to turn the tide against the disease, which is the number one cause of preventable blindness around the world.

Saudi Arabia eliminates trachoma as a public health problem

International Coalition for Trachoma Control

The Kingdom of Saudi Arabia has been officially validated by the World Health Organization (WHO) for eliminating trachoma as a public health problem. Saudi Arabia is the 12th country to achieve this milestone globally and the fourth country in the WHO Eastern Mediterranean Region to do so. Trachoma, the world’s leading infectious cause of blindness, was successfully eliminated in the country alongside efforts to integrate trachoma interventions into its national eye care programme. Furthermore, increased cross-ministerial collaboration between the Ministry of Health, Ministry of Education and of Ministry of Environment, Water and Agriculture, helped to improve health education and environmental determinants of health.
