The rapid decline in effectiveness of a widely used anti-malaria drug treatment on the Thailand-Myanmar border is linked to the increasing prevalence of specific mutations in the malaria parasite itself, according to a paper published in The Clinical infectious Disease Journal.
AMR and scrub typhus among Chiangrai Unit's research priorities
19 May 2021
Which infections are most common in the Chiangrai region? How should we treat them and how can we improve diagnostic? Which strategies are most effective in directing antibiotic treatment? Blog by Carlo Perrone, research physician based at the Chiang Rai Clinical Research Unit in Chiangrai, Thailand.
Researchers call for access to Ivermectin for young children
19 March 2021
Millions of children weighing less than 15kg are currently denied access to Ivermectin treatment due to insufficient safety data being available to support a change to the current label indication. The WorldWide Antimalarial Resistance Network’s new meta-analysis provides evidence that supports removing this barrier and improving treatment equity.
Evidence supports WHO recommendation for primaquine combined with ACTs to block Plasmodium falciparum transmission
12 February 2021
Evidence from a new study, initiated by the Primaquine Roll Out Group and conducted at WWARN, supports the World Health Organization (WHO) recommendation for use of 0.25mg/kg dose of primaquine (PQ) combined with artemisinin-based combination therapies (ACT) to block Plasmodium falciparum transmission.
Check-list recommended to improve reporting of microscopy methods and results in malaria studies
13 January 2021
A study to explore the variations of how microscopy methods are reported in published malaria studies has recommended standardised procedures should be implemented for methodological consistency and comparability of clinical trial outcomes.
The COVID-19 vaccine: do we know enough to end the pandemic?
7 December 2020
Blog by Rima Shretta. Preliminary efficacy results from three vaccine candidates currently in Phase 3 trials have shown an efficacy of more than 90% against the development of symptomatic COVID-19. While these results are promising, all vaccines are in relatively early stages of testing. A comprehensive and transparent roadmap is urgently needed, to determine how limited doses of the first vaccines to be licensed will be distributed, together with which groups will initially be prioritized.
New study on the risk of Plasmodium vivax parasitaemia after Plasmodium falciparum malaria
1 December 2020
A new study quantifying the high risk of Plasmodium vivax parasitaemia after treatment of Plasmodium falciparum malaria aims to identify populations in which a policy of universal radical cure, combining artemisinin-based combination therapy with a hypnozoitocidal antimalarial drug, would be most beneficial.
Oxford Global Research

Oxford is world-famous for research excellence and home to some of the most talented people from across the globe. To showcase our global research, the University launched a Global Research Map, highlighting areas of research we are conducting overseas.
Large scale systematic review details causes of non-malarial febrile illnesses globally and identifies research priorities
21 September 2020
A series of articles that set out to explore the global distribution of infections that cause non-malarial febrile illness has been published in BMC Medicine. The series brings together the results of large-scale systematic reviews of the causes of fever in Africa, Latin America, and Southern and South-Eastern Asia, and has helped identify major knowledge gaps, geographical differences, priority areas for diagnostics research and development, and enabled the most comprehensive systematic review of literature to date.
Microscopy standards to harmonise methods for malaria clinical research studies
10 September 2020
Research Malaria Microscopy Standards (ReMMS) applicable to malaria clinical research studies have been published in Malaria Journal. The paper describes the rationale for proposed standards to prepare, stain and examine blood films for malaria parasites.
Medicine Quality Scientific Literature Surveyor
21 July 2020
IDDO and MORU released its Medicine Quality Scientific Literature Surveyor. The surveyor delivers summaries of published scientific reports on the quality of the classes of essential medicines listed below, across regions and over time. We hope it will help medicine regulators, scientists, health professionals, purchasers and officials fill critical information gaps.
PAL forest malaria prophylaxis study begins in Cambodia
29 April 2020
The Epidemiology Department of MORU and National Malaria Control Programme, Cambodia (CNM) have begun to implement a study to assess the efficacy of prophylaxis with artemether-lumefantrine (PAL) against forest malaria in Siem Pang District, north-eastern Cambodia bordering Laos.
COVID-19 Therapeutics Accelerator awards $20 million in initial grants to fund clinical trials
30 March 2020
Researchers at MORU and two institutions in the US (University of Washington and La Jolla Institute for Immunology) receive grants from the COVID-19 Therapeutics Accelerator, a large-scale initiative launched by the Bill & Melinda Gates Foundation, Wellcome, and Mastercard to speed the development of and access to therapies for COVID-19.
Triple drug combinations effective against drug-resistant malaria
11 March 2020
Adding a third anti-malaria drug to current artemisinin-combination therapies (ACTs) provides effective treatment against multidrug-resistant falciparum malaria in Southeast Asia, say Oxford researchers in a study in The Lancet. Using TACTs should extend current malaria drugs so drug-resistant malaria doesn't kill millions more and derail hopes of controlling and eliminating malaria.
Why is WHO failing women with falciparum malaria in the first trimester of pregnancy?
6 March 2020
From The Lancet Correspondence. In the opening to the 2019 World Malaria Report, entitled Leaving no one behind in the march to a malaria free world, the WHO’s Director-General notes that the scourge of malaria continues to strike hardest against pregnant women and children in Africa.
Global study highlights the extent and impact of drug-resistant enteric fever and the urgent need for new approaches
23 December 2019
A new study conducted by Christiane Dolecek and colleagues analysed data on antimicrobial resistance of the bacteria Salmonella Typhi and Salmonella Paratyphi, from around the globe, spanning the time from 1990 to 2018. The study highlights the impact of drug resistance and the urgent need for interventions.
New research supports co-administration of primaquine with artemisinin-based combination therapies for P. vivax malaria
8 October 2019
An individual patient data meta-analysis of 2,017 patients from 19 studies has found a high risk of recurrence following treatment of P. vivax malaria with artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) unless they are co-administered with primaquine. The research supports recommendations that these artemisinin-based combination therapies (ACT) should be combined with primaquine.
MORU's new Critical Care Asia Network: 42 ICUs in 9 countries
18 September 2019
In partnership with the Wellcome Innovations Flagship Programme, MORU launched its Critical Care Asia Network project with its first investigators’ meeting on 19-20 Aug in Bangkok. The project will establish an Asian ICU network across 42 ICUs in nine countries and implement a setting-adapted electronic registry.
Antimalarial treatments less effective in severely malnourished children
24 July 2019
MORU researchers have found that severe malnutrition is associated with lower exposure to the antimalarial drug lumefantrine in children treated with artemether-lumefantrine, the most common treatment for uncomplicated falciparum malaria. The study, which is the first to specifically address this, calls urgently for further research into optimised dosing regimens for undernourished children.
Rapidly spreading multidrug-resistant parasites render frontline malaria drug ineffective in southeast Asia
23 July 2019
A rapidly evolving multi-drug resistant lineage of P. falciparum malaria parasites continues to spread in South East Asia, leading to alarmingly high treatment failure rates in Cambodia, Thailand and Vietnam for DHA-piperaquine, one of the world’s most important anti-malaria drugs.
New study shows faster way to cure vivax malaria
19 July 2019
A large clinical trial in Africa and Asia has shown that a 7 day course of high dose primaquine, a drug used to treat P. vivax malaria, is well tolerated and just as effective as the current standard 14 day regimen, according to a study published this week in The Lancet. These findings have important implications for the treatment and elimination of vivax malaria in the Asia Pacific.
