International Congress for Tropical Medicine & Malaria
18-22 September 2016, Brisbane Australia
CONFERENCE REPORT
“Having Australia host this international conference on tropical medicine and malaria is testimony to the world class research undertaken here, and our
commitment to global health by understanding and addressing some of the world’s most devastating, but neglected tropical diseases.”
ASID President Professor Cheryl Jones The XIX International Congress for Tropical Medicine and Malaria (ICTMM 2016) was held at the Brisbane Exhibition and Convention Centre from 18-22 September, attracting over 1500 attendees, with invited speakers from 14 different countries. It was the first time for this event to be held in Australia. Topics included tropical medicine, malaria, parasitology, infectious diseases, zoonoses,
veterinary and one health, travel medicine and more. The Australasian Society for Infectious Diseases (ASID) co-hosted the Congress together with The Australian Society for Parasitology Inc (ASP). ASID’s biennial Zoonoses Conference and the inaugural Barrie Marmion Award for Research in Zoonoses were incorporated into the program.
TROPICAL MEDICINE HIGHLIGHTS: Malaria
The Congress opened with Professor John Reeder,
WHO, on the evolution of The Special Programme
for Research and Training in Tropical Diseases
(TDR), a global programme of scientific
collaboration that helps facilitate, support and
influence efforts to combat diseases of poverty.
He was followed by Dr BT Slingsby, CEO of Global
Health Innovative Technology Fund (GHIT), a
public-private partnership that leverages Japanese
innovation and leadership to advance R&D for
novel health technologies for the developing world. Innovative public-private partnerships to
stimulate R&D were a major theme of the Congress.

AUSTRALIAN MALARIA RESEARCH
From Australia, ASID’s Professor James McCarthy, QIMR, presented on the use of experimental
human malaria infection to improve the understanding of the pathogenesis of malaria and to
develop new diagnostics, drugs and vaccines. He was interviewed by Dr Norman Swan from ABC’s
Health Report in the lead up to the conference.

MALARIA VACCINE WITHIN REACH
Dr Stephen Hoffman: Sanaria’s PfSPZ malaria vaccine has yielded ‘unprecedented protection in
clinical trials and is found to be safe, easily administered and protects for at least a year’. The vaccine
received FDA fast track designation during the conference. By March next year Sanaria hope to have
completed phase 2 trials to establish dosage regimen with a view to launching the vaccine in March
2019. Strategy involves pursuing 2 parallel tracks to licensure: a vaccine for use in endemic regions
and a vaccine for travellers, military and expat workers. Hoffman’s presentation focused on how to
overcome the challenges faced in using this for elimination campaigns.

COLLABORATION PAVES THE WAY
Associate Professor Matthew Todd: A unique “open source” study has created a collaborative
patent-free environment that will accelerate the development of new malaria treatments, according
to lead researchers at the Univ. of Sydney. Read the media release or the research article in ACS
Dr Jorg Mohrle: A new potent antimalarial development candidate with potential for both treatment
and prevention of malaria has been identified by a collaboration between Medicines for Malaria
Venture (MMV) and an international network of partners. Read the media release.
TROPICAL MEDICINE HIGHLIGHTS: TB, HIV, Zika
Snapshot: TB Priorities for Australia
The soon-to-launched National Strategic Plan will inform
those involved in TB care but also other Commonwealth
and State and Territory Departments in areas where a
'Health in All Policies' approach is needed. The plan aligns
with WHO guidance on how to approach the elimination of
TB from the global health landscape.
For Australia this will mean targeting populations within our community that have higher rates of TB
and higher risk of developing TB. Many of these persons may not have yet arrived in Australia as
nearly 90 per cent of Australia's active TB cases were born overseas, usually in a country with high
TB incidence. TB usually takes months/years to develop after initial infection but can take decades.
Snapshot: HIV Professor Sharon Lewin updated the audience on the search
for an HIV cure. The world simply can’t afford to put
everyone with HIV on lifelong treatment, she said, and a
cure will be essential.
Today, achieving long-term remission of the virus is
considered a “functional cure” for HIV. However,
measurement of such remission needs to be standardized
across the industry to allow for better comparison of
research on this topic. Other cure studies presented include
“shock and kill” in various European countries, whereby the
virus is activated and then treated with a vaccine; and a
clinical trial of adults who initiated treatment early and then
stopped medications while being closely monitored. HIV
cure research can benefit from advances in cancer research,
as well, Lewin concluded.

Snapshot: Zika Virus Zika Virus continued to peak interest, with Dr Federico Costa providing an update from Brazil. Their
current perspective is that ZIKV causes a congenital infection and syndrome distinct from other
causes of microcephaly. However, he raised caveats in attributing the entire burden of microcephaly
to congenital Zika syndrome. An effective response to this emergency will require systematic
investigation of pregnant women and newborns, a serologic test that detects exposure in utero and
stratifies risk among women of child bearing age, and a fundamental understanding of all modes of
ZIKV transmission in order to project future trends and risks.
Travel Medicine: A message for GPs Given the boom in travel, tropical medicine should not be considered an exotic field for GPs, writes ICTMM Presenter Dr Colleen Lau. Read her article in Medical Observer and ASID’s media release.
BURDEN OF DISEASE: Aboriginal Populations
Snapshot: Global burden of
neglected diseases
PLOS Neglected Tropical Diseases co-Editor-in-
Chief Dr Peter Hotez’ presentations brought into
sharp focus the changing health landscape, with
widespread poverty-related neglected diseases
occurring predominantly among the poor living in
wealthy G20 countries. Such findings represent a
significant departure for the way in which we usually think about global health and as a result have
important policy implications for the G20 leaders and governments. This concept - “Blue Marble
Health” - was first expressed in 2011 and is now in a new book with 38 new research papers.
Investigators are invited to continue contributing new papers to this collection. Read more in PLOS.
Indigenous Australia Dr Peter Hotez also focused on diseases of poverty in global Aboriginal populations, who account for
15 per cent of global poverty even though they comprise only 5 per cent of the global population.
In Australia, the greatest burden of neglected tropical diseases is in Indigenous populations in
remote and rural areas of the Northern Territory:
Strongyloidiasis: hyperendemic and often associated with (HTLV-1) co-infection
Hookworm: caused by Ancylostoma duodenale
Intestinal protozoan infections
Ectoparasitic scabies
Secondary group A streptococcal (GAS) infections & impetigo (extremely common)
Post-streptococcal sequelae: including glomerulonephritis and rheumatic heart disease. (In
some cases secondary staphylococcal infections occur.)
Trachoma: still common in remote rural areas, although recently the Australian government
committed to eliminating this disease.
Melioidosis (Burholderia pseudomallei' infection): also common during the wet season.
ASID Focus: Rheumatic Fever
ASID issued a media release from the Congress on Rheumatic Fever:
“Rheumatic Fever is a disease of poverty and neglect, normally associated with developing
countries. However, the highest rates of Rheumatic Fever in the world are actually found here, in
Australia’s Indigenous children.”
Professor Bart Currie, Director of RHD Australia and ASID Secretary.
The Australian guideline for prevention, diagnosis and management of acute rheumatic fever and rheumatic heart disease provides a clear opportunity to turn this around by identifying standards of care, introducing evidence based management strategies and ensuring high-risk populations receive the same standard of care as that available to other Australians. Read ASID’s media release.
TROPICAL MEDICINE HIGHLIGHTS: Paediatrics and Mycology
ASID Focus: PAM
Research presented at the Congress and then published in the Medical Journal of Australia (MJA)
drew attention to a very rare but fatal brain infection mostly affecting children. Primary Amoebic
Meningoencephalitis (PAM) is caused by amoeba such as Naegleria fowleri and is typically found in
warm fresh water, such as ponds, lakes, rivers, hot springs and poorly maintained municipal water
supplies. Rural and remote communities are particularly at risk, where hot bore water and long
surface pipelines promote the growth of large concentrations of the disease-causing amoeba. ASID
President Professor Cheryl Jones warned health professionals and communities to be on alert to
PAM with summer approaching, and respond immediately to any suspected infections by alerting
their laboratories to look for amoebae.

TROPICAL MEDICINE HIGHLIGHTS: Mycology
The ASID-run Tropical Mycology session at the ICTMM included presentations by Ed Zulstra, Wieland
Meyer and Isabella Gremiao.
Fungal Diagnostics in Resource Poor Settings
Wieland Meyer and Debbie Marriott
The global burden of fungal disease is difficult to assess but likely to be significantly under-estimated due to inadequate surveillance, lack of recognition of fungal infection and poor diagnostic tests.
However, it is likely that fungal infections add a substantial burden to health care making rapid, accurate and affordable diagnosis essential.
Diagnostic modalities include direct microscopy, histopathology, culture, antigen testing, molecular techniques.
This presentation discussed the pros and cons of each. Read a news article in the Lancet: “Bringing fungal infections in from the cold”

SNAPSHOT: PUBLIC HEALTH IN THE PACIFIC
ASID Focus: Antimicrobial Resistance Nicola Townell
Pacific Island countries are developing and implementing national AMS programs.
They face significant challenges: lab detection of resistant organisms + surveillance, lack of
antimicrobial guidelines, poor awareness and understanding of AMR and infection control
practices, lack of local leadership and external support.

ASID Focus: Newly Recognised Cause of Chronic Skin Ulceration
Sally Roberts
Haemophilus ducreyi is the causative agent of chancroid, a genital ulcer disease common in developing countries.
There is increasing evidence to support its previously unrecognised role as a causative agent of
chronic skin ulceration in children in South Pacific Island Countries and Territories (PICT).
2 recent studies in PNG and SI have demonstrated high rates of H. ducreyi in skin lesions.
Additional work is needed to better understand the role of H. ducreyi in chronic skin ulceration.
Read a study by Sally Roberts in PLOS Neglected Tropical Diseases
Role of Tropical Islands in Globalising of Emerging Arboviruses Van-Mai Cao Lormeau Zika virus (ZIKV) appeared for the first time in the Pacific in 2007, expanded regionally and, in 2015,
emerged in Brazil. This study found that remote islands, with small populations mostly
immunologically naïve for new emerging arboviruses, combined with an environment highly suitable
for mosquito-borne diseases, should be considered as ideal hubs for virgin soil outbreaks of such
viruses, and subsequent geographic expansion through international travel. In addition, if remote
tropical islands experience outbreaks before more populated continental countries, such areas could
serve as sentinel sites.
Cervical Cancer Prevention in Emerging Nations Ian Frazer
The HPV vaccine has been successfully delivered to preteen girls in Bhutan and Vanuatu, but
sustaining the programs has proven challenging despite donated vaccine, and government and
community support. Different modes of cervical screening have been trialled in Vanuatu, and the
best combination of sensitivity and specificity was obtained with HPV testing amongst over 30 year
olds. The CareHPV test has been successfully delivered under tropical conditions, but central
laboratory facilities are necessary for reagent storage. Provision of QA and QC, and assuring
compliance with follow up from positive screening tests remains a challenge.
