  • Warning to New Zealand travellers over dengue fever outbreaks

    5 August 2019 - New Zealand Herald

    The Ministry of Health is warning New Zealanders embarking on tropical holidays to "fight the bite", amid outbreaks of mosquito-borne dengue fever in Bangladesh and Philippines. Fourty-seven people were diagnosed with dengue fever in New Zealand in May and June after travelling overseas, marking an increase of 14 people compared with the same months last year. Half of those people had travelled to Fiji, with others having visited Indonesia, the Cook Islands, Malaysia, Tahiti, Tonga, Tuvalu and Vietnam. Director of Public Health Carolyn McElnay urged travellers to cover up and take precautions to avoid being bitten.

  • From Townsville to Tuvalu: health and climate change in Australia and the Asia Pacific region

    31 July 2019 - Global Health Alliance Australia

    Mason Littlejohn et al.,

    Most people accept that climate change is transforming the global atmosphere and environment. Yet far fewer understand the significant impacts that climate and environmental change are having on human health. In the Asia Pacific region, climate change is raising sea levels, exacerbating the severity of natural disasters, reducing nutrition levels in food and increasing disease produced by unclean water. All present substantial risks for the health of humans, including Australians. This policy paper highlights evidence and case studies to show how climate and environmental change will affect human health in the Asia Pacific region. It provides proposals for how Australian governments - federal, state and local - might respond to this challenge, arguing that Australia’s aid, health and agricultural portfolios have an opportunity to develop policies that build resilience in our region to the impacts of climate change on human health. Such an approach would elevate Australia’s standing in the region. The benefits are also closer to home, in terms of reduced health risks, and improved political, health and economic security for Australians.

  • Overcoming the ‘tyranny of the urgent’: integrating gender into disease outbreak preparedness and response

    28 July 2019 - EBSCO

    Julia Smith

    This article contributes to discussions on the gender dimensions of disease outbreaks, and preparedness policies and responses, by providing a multi-level analysis of gender-related gaps, particularly illustrating how the failure to challenge gender assumptions and incorporate gender as a priority at the global level has national and local impacts. The implications of neglecting gender dynamics, as well as the potential of equity-based approaches to disease outbreak responses, is illustrated through a case study of the Social Enterprise Network for Development (SEND) Sierra Leone, a non-government organisation (NGO) based in Kailahun, during the Ebola outbreak.

    Climate warming could increase malaria risk in cooler regions

    27 June 2019 - Physics.org

    Malaria parasites develop faster in mosquitoes at lower temperatures than previously thought, according to researchers at Penn State and the University of Exeter. The findings suggest that even slight climate warming could increase malaria risk to hundreds of thousands, if not millions, of people—including travelers—in areas that are currently too cold for malaria parasites to complete their development. The researchers used two of the most important malaria-hosting mosquito species in the world—Anopheles stephensi and Anopheles gambiae—to conduct their experiments. They maintained these malaria-infected mosquitoes in the laboratory under a variety of temperatures ranging from 16 to 20 degrees Celsius, or 60 to 68 degrees Fahrenheit. They maintained a separate control set of mosquitoes at 27 degrees Celsius, or about 80 degrees Fahrenheit, which is the temperature at which malaria transmission is typically highest. The traditional model estimates that parasites in the mosquito take 56 days to develop at temperatures just above the minimum threshold for development—a cool 18 degrees Celsius, or 64 degrees Fahrenheit. However, the current study shows that as few as 31 days are required for such development for Anopheles stephensi. The researchers also found that variation in temperature at this cooler end of the range promotes faster parasite development. Parasites developed in as few as 27 days at 18 degrees Celsius.

    World-first gathering showcased health security's past and future

    27 June 2019 - The University of Sydney

    More than 900 members of the global health security community gathered in Sydney to participate in the first international scientific conference on Global Health Security, organised by Associate Professor Kamradt-Scott and Associate Professor Rebecca Katz from Georgetown University. High-profile speakers included Australia’s Federal Minister for Health Greg Hunt MP and representatives from the NSW Government, Peter Sands from the Global Fund for HIV/AIDS, TB and Malaria, Assistant Director-General and Regional Directors from the World Health Organisation, leaders from several Centers for Disease Control and Prevention, Médecins Sans Frontières, the Bill and Melinda Gates Foundation and many more. “Achieving global health security requires collaboration across disciplines, industries and seniority, and Associate Professor Katz and I are thrilled that our conference was able to bring together members of the global health security community for the first time to measure progress, determine gaps, and identify new opportunities to enhance national, regional and global health security” Dr Kamradt-Scott said.

    Malaria hijacks your genes to invade your liver

    27 June 2019 - Physics.org

    In the search for new weapons against malaria, most drug development has focused on the parasites that cause the disease. Duke University researchers are trying a different tack, instead of targeting the malaria parasite directly, the idea is to discover drugs aimed at the human cell machinery conscripted to do malaria's dirty work. In a new study, a team led by assistant professor of chemistry Emily Derbyshire has identified more than 100 human genes that malaria parasites commandeer to take up residence inside their victim's liver during the 'silent' earlier stages of infection, before symptoms appear. For this study, researchers used snippets of silencing RNA to trick human liver cells into tamping down each of roughly 7,000 protein-coding genes. Then they infected the liver cells with a mouse malaria parasite similar to the Plasmodium species that causes human malaria.

    Cambodia sees rise in dengue fever cases

    27 June 2019 - Xinhua

    Cambodia reported 13,000 cases of dengue fever from January to June 24, about five-fold rise over the same period last year, Huy Rekol, director of the National Center for Parasitology, Entomology and Malaria Control, said on Thursday. In a bid to control the outbreak of the virus, about 300 tons of Abate (a chemical substance used to put in water pots to kill larvae) has been handed out to households, he said, adding that health officials have also been spraying insecticide to target Aedes mosquitoes which are the carrier of the dengue virus. According to a health ministry report, there were 24,684 cases of dengue fever with 23 deaths last year compared with 6,372 cases with three deaths in 2017.
