Early warning climate indices for malaria and meningitis in tropical ecological zones
2020
AbstractThis study aims at assessing the impacts of climate indices on the spatiotemporal distribution of malaria and meningitis in Nigeria. The primary focus of the research is to develop an Early Warning System (EWS) for assessing climate variability implications on malaria and meningitis spread in the study area. Both climate and health data were used in the study to determine the relationship between climate variability and the occurrence of malaria and meningitis. The assessment was based on variations in different ecological zones in Nigeria. Two specific sample locations were randomly selected in each ecological zone for the analysis. The climatic data used in this study are dekadal …
Marco Internacional de Acciones. VIH/SIDA, Tuberculosis, Malaria y Drogas
2002
El SIDA/VIH en el marco las enfermedades infecciosas, y en su relación con el consumo de drogas ha sido considerado por el Consejo Nacional de Seguridad de los EE.UU. como una cuestión de seguridad mundial y una amenaza para la democracia global. En este trabajo se expone de modo esquemático el estado actual a escala mundial de la investigación e intervención económica y social respecto a este problema fundamen¬talmente dentro del ámbito de proyección de la Unión Europea, Naciones Unidas y las respectivas Organizaciones Mundiales de la Salud, del Desarrollo Económico y del Comercio.
Visiting Friends and Relatives (VFRs) travelers and imported malaria in the Palermo district (Sicily).
2014
Abstract Introduction. Although Italy has been malaria-free since 1970, the infection is commonly introduced into the country by travelers and immigrants from endemic areas. The term VFRs refers to immigrants from malaria-endemic countries who are regularly resident in a malaria-free area, and who travel to their countries of origin to visit friends and relatives (VFRs). This group is at special risk of malaria as they are unaware of having lost their transitory immunity to the disease. Methods. We conducted a retrospective study at the International Travelers Department of Palermo (Italy), examining records of malaria cases (67) reported over the period from 1998 to 2013. Results. VFRs rep…
[Visiting friends and relatives (VFRs) role on imported malaria: a literature review]
2015
In the last decades, increased numbers of travel to tropical destinations in combination with the enormous influx of immigrants have led to an increased number of imported malaria cases in developed countries. There is a group of immigrants regularly resident in malaria free areas, which travel to malaria endemic countries to visit their friends and relatives (VFRs). VFRs represent a high-risk group of contracting malaria. Publications presenting original data on malaria in VFRs were selected for a literature review.We considered all data regarding prevalence of malaria in VFRs compared to the other groups of travelers, length of trip, group characteristics such as age, sex, country visited…
PLASMODIUM DOMINAN DALAM NYAMUK ANOPHELES BETINA (Anopheles spp.) PADA BEBERAPA TEMPAT DI DISTRIK MANOKWARI BARAT
2018
Malaria contagious by mosquito Anopheles Betina bringing protozoa parasite in its body (Plasmodium). Plasmodium there are four specieses that is Plasmodium vivax, Plasmodium ovale, Plasmodium malariae and Plasmodium falciparum, but often becomes pathogen that is Plasmodium vivax and Plasmodium falciparum. As for intention of this research is to identify Plasmodium which is dominant at female Anopheles mosquito (Anopheles spp.) and knows distribution pattern of female Anopheles mosquito (Anopheles spp.) in some places in Districts Manokwari Barat.
 Based on research result done to four locations that is area Amban, Wosi, Sanggeng and Kota is found [by] 1024 mosquito tails. From the amou…
Risk estimation for air travel-induced malaria transmission in central Europe – A mathematical modelling study
2019
Abstract Background Aim of our study was to identify conditions under which malaria transmission caused by imported infectious mosquitoes or travellers could occur at large central European airports, and if such transmission could be sustained by indigenous mosquitoes. Methods We developed a deterministic and a stochastic compartmental Susceptible-Exposed-Infectious-Recovered-Susceptible (humans)/Susceptible-Exposed-Infectious (mosquitoes) model with two mosquito (imported Anopheles gambiae, indigenous A. plumbeus) and three human (travellers, airport personnel exposed/not exposed to imported A. gambiae) populations. We assessed various scenarios to identify combinations of model parameters…
Coalition: Advocacy for prospective clinical trials to test the post-exposure potential of hydroxychloroquine against COVID-19
2020
Our coalition of public health experts, doctors, and scientists worldwide want to draw attention to the need for high-quality evaluation protocols of the potential beneficial effect of hydroxychloroquine (HCQ) as a post-exposure drug for exposed people. In the absence of an approved, recognized effective pre or post-exposure prophylactic drug or vaccine for COVID-19, nor of any approved and validated therapeutic drug, coupled with social and political pressure raised by publicity both regarding the potential beneficial effect of hydroxychloroquine (HCQ) as well as potential risks from HCQ, we urge the immediate proper clinical trials. Specifically, we mean using HCQ for post-exposure of peo…
Health sector spending and spending on HIV/AIDS, tuberculosis, and malaria, and development assistance for health: progress towards Sustainable Devel…
2020
BACKGROUND: Sustainable Development Goal (SDG) 3 aims to "ensure healthy lives and promote well-being for all at all ages". While a substantial effort has been made to quantify progress towards SDG3, less research has focused on tracking spending towards this goal. We used spending estimates to measure progress in financing the priority areas of SDG3, examine the association between outcomes and financing, and identify where resource gains are most needed to achieve the SDG3 indicators for which data are available. METHODS: We estimated domestic health spending, disaggregated by source (government, out-of-pocket, and prepaid private) from 1995 to 2017 for 195 countries and territories. For …
Ecologie évolutive de la malaria aviaire : approches expérimentales des relations entre Plasmodium relictum et le canari domestique
2010
Host-parasite interaction became one of the main topics of evolutionary sciences researches. One of the major issues raised by these studies is to understand why some parasites cause fatal diseases while others remain relatively mild to their hosts. In this challenge attempting to take up the evolutionary biologist and the medical sciences, we focused on avian malaria, and more specifically on its most common parasite: Plasmodium relictum. In performing experimental infections in domestic canaries (Serinus canaria), we wanted to understand what factors related to parasite and birds characteristics, could influence Plasmodium relictum virulence. We highlighted that factors such as infectious…
Ecologie évolutive de la malaria aviaire : effets des caractéristiques de l'hôte et de l'environnement
2012
Host-parasite interactions are one of the main topics in evolutionary sciences. This complex coevolution depends on several trade-offs and can be influenced by environmental factors. Here, we propose to study host-parasite interactions with a multi-level approach, using experimental and natural population studies, focusing on avian malaria parasites. First, we studied the effect of host characteristics, and more precisely the immune system. The immune system confers benefits in terms of protection against the parasite, but can also generated immunopathological costs. Life history traits, like age or social status, appear to modify parasitemia but not prevalence. In a second part, we evaluat…
