Vector control: The last bite : Nature : Nature Publishing Group

Vector control: The last bite : Nature : Nature Publishing Group | Medicina Tropical & Salud del Viajero | Scoop.it
Preventing mosquitoes from transmitting the malaria parasite is a crucial piece of the eradication puzzle.

Mosquitoes are the ideal vector — they provide a safe haven for a parasite to reproduce, then inject it directly into the human bloodstream. What's more, mosquitoes are a moving target. The females of nearly 70 species of Anopheles transmit malaria, biting indoors and out. They have evolved resistance to once highly effective pesticides1, and some species might have even changed their behaviour to bite earlier in the evening when people are less likely to be shielded by bed nets.

Amazonian malaria: Asymptomatic human reservoirs, diagnostic challenges, environmentally driven changes in mosquito vector populations, and the mandate for sustainable control strategies • Malaria ... | Medicina Tropical & Salud del Viajero | Scoop.it

Across the Americas and the Caribbean, nearly 561,000 slide-confirmed malaria infections were reported officially in 2008. The nine Amazonian countries accounted for 89% of these infections; Brazil and Peru alone contributed 56% and 7% of them, respectively. Local populations of the relatively neglected parasite Plasmodium vivax, which currently accounts for 77% of the regional malaria burden, are extremely diverse genetically and geographically structured. At a time when malaria elimination is placed on the public health agenda of several endemic countries, it remains unclear why malaria proved so difficult to control in areas of relatively low levels of transmission such as the Amazon Basin. We hypothesize that asymptomatic parasite carriage and massive environmental changes that affect vector abundance and behavior are major contributors to malaria transmission in epidemiologically diverse areas across the Amazon Basin. Here we review available data supporting this hypothesis and discuss their implications for current and future malaria intervention policies in the region. Given that locally generated scientific evidence is urgently required to support malaria control interventions in Amazonia, we briefly describe the aims of our current field-oriented malaria research in rural villages and gold-mining enclaves in Peru and a recently opened agricultural settlement in Brazil.

Plasmodium falciparum Malaria in the Peruvian Amazon, a Region of Low Transmission, Is Associated with Immunologic Memory

The development of clinical immunity to Plasmodium falciparum malaria is thought to require years of parasite exposure, a delay often attributed to difficulties in developing protective antibody levels. In this study, we evaluated several P. falciparum vaccine candidate antigens, including apical membrane antigen 1 (AMA-1), circumsporozoite protein (CSP), erythrocyte binding antigen 175 (EBA-175), and the 19-kDa region of merozoite surface protein 1 (MSP119). After observing a more robust antibody response to MSP119, we evaluated the magnitude and longevity of IgG responses specific to this antigen in Peruvian adults and children before, during, and after P. falciparum infection. In this low-transmission region, even one reported prior infection was sufficient to produce a positive anti-MSP119 IgG response for >5 months in the absence of reinfection. We also observed an expansion of the total plasmablast (CD19+ CD27+ CD38high) population in the majority of individuals shortly after infection and detected MSP1-specific memory B cells in a subset of individuals at various postinfection time points. This evidence supports our hypothesis that effective antimalaria humoral immunity can develop in low-transmission regions.

Malaria Treatment and Prophylaxis in Endemic and Nonendemic Countries

Artemisinin combination treatment is currently the preferred treatment strategy to combat malaria. However, the drug costs are considerably higher than for previously used therapies. This review discusses the cost–effectiveness of current malaria treatment and prophylaxis in endemic and nonendemic countries. For endemic countries, a systematic search for economic evaluations (i.e., cost–effectiveness, cost–utility and cost–benefit analyses) was conducted, looking at the use of Artemisinin combination treatments in children, pregnant women and other adults. In total, 24 studies were identified investigating the cost–effectiveness of malaria treatments with the focus on uncomplicated malaria, severe or prereferral treatment, all in combination with adequate diagnosis, and malaria prevention by intermittent preventive treatment, respectively. In areas with both Plasmodium falciparum and Plasmodium vivax transmission, artemether–lumefantrine and dihydroartemisinin–piperaquine, respectively, are currently the most cost-effective treatment options. Treatment of severe malaria with artesunate is more cost effective compared with treatment with quinine. For patients that live more than 6 h away from an appropriate healthcare facility, prereferral treatment proved to be more cost-effective compared with no prereferral intervention.

A guide to staying well at high altitude

A guide to staying well at high altitude | Medicina Tropical & Salud del Viajero | Scoop.it

Know the danger signs
It is normal to have some headaches when you are first above 2,500m. Rest, drink and medicate as you would at sea level. Breathlessness is normal on exertion at altitude – but above 3,000m, watch for breathlessness when resting. A cough; a severe, persistent headache; nausea; loss of coordination or disorientation all are signs of Acute Mountain Sickness (AMS). This potentially fatal condition demands rapid descent.

Cordillera Huayhuash, Peru
The 12-day 170km circuit of the most easterly range of the Andes is largely between 4,000 and 5,000m. Spectacular glacier-shrouded peaks here soar to 6,635m.

Doxycycline for Malaria Chemoprophylaxis and Treatment: Report from the CDC Expert Meeting on Malaria Chemoprophylaxis

Doxycycline for Malaria Chemoprophylaxis and Treatment: Report from the CDC Expert Meeting on Malaria Chemoprophylaxis | Medicina Tropical & Salud del Viajero | Scoop.it

Doxycycline, a synthetically derived tetracycline, is a partially efficacious causal prophylactic (liver stage of Plasmodium) drug and a slow acting blood schizontocidal agent highly effective for the prevention of malaria. When used in conjunction with a fast acting schizontocidal agent, it is also highly effective for malaria treatment. Doxycycline is especially useful as a prophylaxis in areas with chloroquine and multidrug-resistant Plasmodium falciparum malaria. Although not recommended for pregnant women and children < 8 years of age, severe adverse events are rarely reported for doxycycline. This report examines the evidence behind current recommendations for the use of doxycycline for malaria and summarizes the available literature on its safety and tolerability.

Infectious diseases among travellers and migrants in Europe, EuroTravNet 2010

Infectious diseases among travellers and migrants in Europe, EuroTravNet 2010 | Medicina Tropical & Salud del Viajero | Scoop.it

To investigate trends in travel-associated morbidity with particular emphasis on emerging infections with the potential for introduction into Europe, diagnoses of 7,408 returning travellers presenting to 16 EuroTravNet sites in 2010 were compared with 2008 and 2009. A significant increase in reported Plasmodium falciparum malaria (n=361 (6% of all travel-related morbidity) vs. n=254 (4%) and 260 (5%); p<0.001), P. vivax malaria (n=51 (1%) vs. n=31 (0.5%) and 38 (1%); p=0.027) and dengue fever (n=299 (5%) vs. n=127 (2%) and 127 (2%); p<0.001) was observed. Giardia lamblia was identified in 16% of patients with acute diarrhoea, with no significant annual variation. The proportion of acute diarrhoea due to Campylobacter increased from 7% in 2008 to 12% in 2010 (p=0.001). We recorded 121 patients with pulmonary tuberculosis in 2010, a three-fold increase in the proportionate morbidity from 2008 to 2010. In 2010, 60 (0.8%) cases of chronic Chagas disease, 151 (2%) cases of schistosomiasis and 112 (2%) cases of cutaneous larva migrans were reported. Illness patterns in sentinel travellers, captured by EuroTravnet, continue to highlight the potential role of travellers in the emergence of infectious diseases of public health concern in Europe and the relevance of offering medical travel advice and enforcing specific and adequate prophylaxis.

PLoS #NTDs: A Research Agenda for the Control and Elimination of Human Helminthiases

PLoS #NTDs: A Research Agenda for the Control and Elimination of Human Helminthiases | Medicina Tropical & Salud del Viajero | Scoop.it
More than half of the world's population is at risk of helminthiases, and hundreds of millions of people are currently infected with one or more helminth species. Consequences of chronic infection include suffering, stigmatization, subtle and gross morbidity, and premature death. These infections are associated with low work productivity, poor cognitive performance, and slow socioeconomic development, thereby contributing to accentuate poverty and inequality. In the April 2012 issue of PLoS Neglected Tropical Diseases, the Disease Reference Group on Helminth Infections (DRG4) put forward a series of eight reviews that, taken together, outline a compelling research and development (R&D) agenda for the control and elimination of helminth diseases of humans. Emphasis is placed on six major helminth diseases: soil-transmitted helminthiasis; schistosomiasis; lymphatic filariasis; onchocerciasis; food-borne trematodiasis; and cysticercosis/taeniasis. Additionally, an Editorial from Jürg Utzinger provides an overview to all eight reviews and emphasizes the importance of continued research on these six diseases, which together have an enormous global health impact.

DRG4 is part of an independent “think tank” of international experts, established and funded by the Special Programme for Research and Training in Tropical Diseases (TDR), to identify key research priorities through the review of research evidence and input from stakeholder consultations. For more information on the TDR Think Tank and the resulting reports, please visit: http://www.who.int/tdr/stewardship/research-think-tank/en/.

Parasites & Vectors | Abstract | A global map of dominant malaria vectors

Parasites & Vectors | Abstract | A global map of dominant malaria vectors | Medicina Tropical & Salud del Viajero | Scoop.it
Global maps, in particular those based on vector distributions, have long been used to help visualise the global extent of malaria. Few, however, have been created with the support of a comprehensive and extensive evidence-based approach.

Our global map highlights the spatial variability in the complexity of the vector situation. In Africa, An. gambiae, An. arabiensis and An. funestus are co-dominant across much of the continent, whereas in the Asian-Pacific region there is a highly complex situation with multi-species coexistence and variable species dominance.

First-Trimester Malaria: Treatment and Outcomes - Infectious Diseases

These findings are reassuring with regard to the safety of artemisinin derivatives during the first trimester of pregnancy, despite animal studies suggesting potential embryo toxicity. Prospective studies in women are warranted. The present results clearly demonstrate the adverse consequences of malaria — whether asymptomatic or symptomatic — so testing and treatment during all stages of pregnancy should be part of malaria programs. Although both malarial and nonmalarial febrile illnesses are associated with increased risk for miscarriage during the first trimester, the pathological process underlying the increased miscarriage risk with asymptomatic malaria is unclear and likely malaria specific. As emphasized by editorialists, the risk from malaria clearly outweighs the theoretical risk from artemisinin treatment during early pregnancy.
