Eco-epidemiological studies to develop integrated vector surveillance of leishmaniasis vectors in the Americas

Salomón, O.; Quintana, M. One Health and Implementation Research (2022) CC

We developed an integrated vector surveillance (IVS) proposal for cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL) in the Americas, based on eco-epidemiological studies conducted by researchers of the Leishmaniasis Research Network of Argentina. For CL, the transmission was explained in ... more

Assessing the nature of asthma in African epidemiological studies: a scoping review protocol

Ndlovu, V.; Chimbari, M.J.; Sibanda, E. (2020) CC2

Asthma is one of the most common chronic respiratory conditions in the world and is increasing in prevalence, particularly in Africa and other low-income countries. The disproportionately high numbers of premature deaths and severe or uncontrolled cases in many African countries are indicative of th... more

Identifying asthma in population studies: from single entity to a multi-component approach

Marks, G. B. (2005) CC2

Considerable energy has been expended over the last two decades in developing methods for identifying the presence of asthma among participants in population studies. The objective of this endeavour has commonly been to enable epidemiological research on risk factors for asthma, with the ultimate ai... more

Current epidemiological evidence for predisposition to high or low intensity human helminth infection: a systematic review

Wright J.E., Werkman M., Dunn J.C. et al Parasites and Vectors (2018) C2

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them. Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed. Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species. Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition. more

Eradicating Polio in Afghanistan and Pakistan

April Chang, Edgar Chavez, Sadika Hameed et al. Center for Strategic and International Studies (CSIS) (2012) CC

Through 2004, reports showed that polio incidence in Afghanistan was in decline. When the Global Polio Eradication Initiative (GPEI) reported only 30 new cases in 2010, the program was widely hailed as effective and on the road to complete success. However, GPEI and the Afghan Ministry of Health rep... more
