Efforts to control NTDs typically require advice, support and coordination from several international networks. Like tropical medicine in general, the need to bring scientists and clinicians together regularly and discuss their findings is crucial to ensure that the best research is disseminated internationally and eventually translated into optimal control strategies. The International Congress for Tropical Medicine and Malaria (ICTMM) provides such a forum.
This year the 19th ICTMM took place from 18th to 22nd September in Brisbane, Australia. This brought together just over 1,500 delegates. The meeting was jointly organised by the Australian Society for Parasitology (ASP) and the Australasian Society for Infectious Diseases (ASID). I was especially honoured to be awarded a travelling lectureship from the ASP to present and also visit research groups in Australia to instigate future collaboration. This I did by visiting the laboratories of Robin Gasser and Don McManus at the University of Melbourne and Queens Institute of Medical Research (QIMR), Brisbane. Robin and Don each have a tremendous stature in veterinary and medical parasitology, respectively. Both seamlessly blend state-of-the-art molecular studies with field studies and have had significant research programmes advancing the health and well-being of those living in the tropics.
In Melbourne, I gave a departmental seminar and was able to discuss with Robin and his team our ongoing and future work in Ghana and Cameroon. The Gasser lab has been pioneering molecular surveillance of helminth diseases for over thirty years and one of their recent milestones was made by Dr Neil Young in publishing the genome of Schistosoma haematobium. This Nature publication was a tremendous achievement bringing new focus to the control of urogenital schistosomiasis in Africa. Better knowledge of this genome has opened up new ways to study the population biology of this parasite, often revealing how it is able to cause such ill-health across the continent. Furthermore, a precise knowledge of this genome allows us to monitor significant evolutionary changes which may occur to mitigate our efforts to control it with preventive chemotherapy.
In Brisbane, I attended the ICTMM meeting and gave a keynote presentation on schistosomiasis, reporting our recent findings in Cameroon at Barombi Kotto and Mbo, as well as, two other presentations on treatment of pre-school-aged children with intestinal schistosomiasis and management of co-infections of schistosomiasis and giardiasis. Whilst at the conference our viewpoint article in was published which was a timely reminder of how much future work is needed to expand access of praziquantel to those children currently overlooked within control programmes.
Suzy Campbell gave a presentation on the focus of her PhD studies on WASH (Water, Sanitation and Hygiene) for Soil-Transmitted Helminthiasis (STH). It was also a great honour for me to be invited to serve on the IFTM expanded board so we can look forward to 20th ICTMM in 2020 hosted by the Parasitology and Tropical Medicine Association of Thailand.
A particular highlight was learning from Don the steps that his group had taken to develop and evaluate public health education materials used for control of soil-transmitted helminthiasis in China. I recommend that you view the ‘Magic Glasses’ animation and its associated impact has been reported in the New England Journal of Medicine. More broadly, we do not have adequate nor sufficient health education materials presently for use in African schools for several other NTDs. My own previous research on schistosomiasis in Zanzibar has shown that innovative approaches are very much needed to addressing this aspect of influencing positive behavioural change.
