“…Autochthonous malaria cases have been reported in Azerbaijan, France, Georgia, Greece, Italy, Russian Federation, Spain and Ukraine in the same period of time [13,15,25,26]. The possibility of transmission in SMM has been described in endemic zone for malaria [8,12], and presence of a suitable vector in Europe ( Anopheles atroparvus , Anopheles claviger or Anopheles maculipennis ) has also been reported [27,28]. Since the implementation of molecular tests for all symptom-free individuals coming from endemic area is too expensive, the possibility of a re-emergence of malaria ( Plasmodium vivax ) in Europe can only be speculated.…”

BackgroundSubmicroscopic malaria (SMM) can be defined as low-density infections of Plasmodium that are unlikely to be detected by conventional microscopy. Such submicroscopic infections only occasionally cause acute disease, but they are capable of infecting mosquitoes and contributing to transmission. This entity is frequent in endemic countries; however, little is known about imported SMM.The goals of this study were two-fold: a) to know the frequency of imported SMM, and b) to describe epidemiological, laboratorial and clinical features of imported SMM.MethodsA retrospective study based on review of medical records was performed. The study population consisted of patients older than 15 years attended at the Tropical Medicine Unit of Hospital Carlos III, between January 1, 2002 and December 31, 2007. Routinely detection techniques for Plasmodium included Field staining and microscopic examination through thick and thin blood smear. A semi-nested multiplex malaria PCR was used to diagnose or to confirm cases with low parasitaemia.ResultsSMM was diagnosed in 104 cases, representing 35.5% of all malaria cases. Mean age (IC95%) was 40.38 years (37.41-43.34), and sex distribution was similar. Most cases were in immigrants, but some cases were found in travellers. Equatorial Guinea was the main country where infection was acquired (81.7%). Symptoms were present only in 28.8% of all SMM cases, mainly asthenia (73.3% of symptomatic patients), fever (60%) and arthromialgias (53.3%). The associated laboratory abnormalities were anaemia (27.9%), leukopaenia (15.4%) and thrombopaenia (15.4%). Co-morbidity was described in 75 cases (72.1%).ConclusionsResults from this study suggest that imported SMM should be considered in some patients attended at Tropical Medicine Units. Although it is usually asymptomatic, it may be responsible of fever, or laboratory abnormalities in patients coming from endemic areas. The possibility of transmission in SMM has been previously described in endemic zones, and presence of vector in Europe has also been reported. Implementation of molecular tests in all asymptomatic individuals coming from endemic area is not economically feasible. So re-emergence of malaria (Plasmodium vivax) in Europe may be speculated.

“…They are commonly collected along river and lake margins, marshes, irrigation canals and especially in rice fields (primary larval habitat), where aquatic vegetation provides protection from predators and a cooler environment [8,9]. Anopheles atroparvus has been described as an endophilic, most commonly endophagic, and zoophilic species with a marked preference for domestic farm animals [10][11][12][13][14]. Due to its association to human settlements, An.…”

Laboratory colonization and maintenance of Anopheles atroparvus from the Ebro Delta, Spain

et al. 2020

Background: Historically, Anopheles atroparvus has been considered one of the most important malaria vectors in Europe. Since malaria was eradicated from the European continent, the interest in studying its vectors reduced significantly. Currently, to better assess the potential risk of malaria resurgence on the continent, there is a growing need to update the data on susceptibility of indigenous Anopheles populations to imported Plasmodium species. In order to do this, as a first step, an adequate laboratory colony of An. atroparvus is needed. Methods: Anopheles atroparvus mosquitoes were captured in rice fields from the Ebro Delta (Spain). Field-caught specimens were maintained in the laboratory under simulated field-summer conditions. Adult females were artificially blood-fed on fresh whole rabbit blood for oviposition. First-to fourth-instar larvae were fed on pulverized fish and turtle food. Adults were maintained with a 10% sucrose solution ad libitum. Results: An An. atroparvus population from the Ebro Delta was successfully established in the laboratory. During the colonization process, feeding and hatching rates increased, while a reduction in larval mortality rate was observed. Conclusions: The present study provides a detailed rearing and maintenance protocol for An. atroparvus and a publicly available reference mosquito strain within the INFRAVEC2 project for further research studies involving vectorparasite interactions.

“…Population movements suppose a risk for both individual and public health, as travel facilitates the spread of infectious diseases from endemic regions. This may involve the reintroduction of infections in previously unexposed populations and an increased incidence of infections already existing in the host countries [10][11][12][13] .…”

Factors associated with risk behavior in travelers to tropical and subtropical regions

27Background: Recent decades have seen a rise in population movements and, therefore, 28 Results: 66% of travelers received pre-travel advice and 31% took malaria prophylaxis. 37At least one risk behavior was reported by 82.6% of travelers. People travelling for 1-6 38 months had a 3-fold higher likelihood of experiencing risk behaviors than people 39 travelling for <1 month (95%CI 1.54-5.81, p=0.001), and those travelling for >6 months 40 had a 13-fold higher likelihood (95%CI 3.11-56.14, p<0.001) compared with the same 41 group. Increasing age was associated with presenting less risk behaviors.
