    Malaria - Europe - 2017

    Opening date: 11 September 2017 Latest update: 15 September 2017

    Epidemiological summary

    Greece
    As of 17 August 2017, Greece reported five autochthonous cases of P. vivax malaria acquired via vector-borne transmission following a likely exposure in the regions of Dytiki Ellada in West Greece for four cases and Sterea Ellada in Central Greece for one case [6]. Greece reports that these cases resulted from a local transmission following recent introduction of P. vivax in the II.

COMMUNICABLE DISEASE THREATS REPORT Week 37, 10-16 September 2017 area (introduced cases).
    The dates of onset of the cases range between 2 May and 22 July 2017. In addition, Greece reported one locally acquired case of P. falciparum in the region of Ipeiros, in north-west Greece, with date of onset of symptoms between 17 and 23 July 2017. The case, who has no travel history to a malaria-endemic area, was hospitalised for a non-infectious medical condition in a ward where another patient was treated for P. falciparum malaria. The most likely place of exposure for this particular case was a healthcare facility but it was not possible to determine the exact mode of transmission (mosquito vector or of iatrogenic origin). The investigation excluded transmission through blood transfusion, but instead suggested a nosocomial transmission, either mosquito-borne within the heathcare facility or of iatrogenic origin. No locally acquired malaria cases were reported in the area.

    Italy
    On 5 September, Italy reported a fatal case of malaria [33]. The case was a four-year-old girl with no travel history to a malariaendemic country. She was admitted on 13 August 2017 to a hospital in the Veneto region and diagnosed with diabetes mellitus. After returning from the Veneto region, she was admitted to a Trento hospital for her diabetes (16 to 21 August) and later consulted a pharyngitis on 31 August 2017. On 2 September, she was admitted to hospital again and diagnosed with P. falciparum malaria. She was subsequently transferred to the tropical diseases reference centre in Brescia where she died on 4 September. Epidemiological investigations showed that two patients infected with P. falciparum were hospitalised in the same ward during her stay in the Trento hospital. An investigation in the Trento hospital did not identify any breaches of medical procedures that could result in an iatrogenic transmission. Entomological investigations in the Trento area did not reveal the presence of Anopheles mosquitoes. Entomological surveys in Bibione, where the girl spent her holidays, were conducted. Molecular sequencing of the Plasmodium strain from the girl and from the two children hospitalised concomitantly is ongoing.

    France
    On 7 September, France reported two locally-acquired cases of malaria in the department of Allier in the Auvergne-Rh?ne-Alpes region of central France. Both cases attended a wedding that took place between 11 and 16 August 2017 in Moulins, Allier department, France. On 30 August 2017, the first case was diagnosed after admission to hospital in the southwest of France for fever, chills and sweats evolving since 26 August. The patient did not travel abroad and had no risk factors for induced malaria. The only recent trip was to Moulins and its surrounding for attending the wedding. On 1 September, a second case who attended the same wedding was diagnosed upon returning home. The case had onset of symptoms on 26 August 2017 and had neither exposure to induced malaria nor a recent travel history to a malaria-endemic area. The Regional Health Agency of Auvergne-Rh?ne-Alpes implemented active case finding in the neighbouring laboratories and hospitals. None of the wedding attendees reported a recent travel history to a malaria-endemic country or symptoms compatible with malaria. However, an imported case of P. falciparum malaria from Burkina Faso was identified to have stayed in Moulins and its surroundings for several days within the two weeks before the wedding. Entomological investigations conducted in the areas visited by the imported case and autochthonous cases did not find evidence of the presence Anopheles plumbeus, a potential competent vector of P. falciparum. The French National Reference Centre for Malaria is gathering samples for molecular typing to assess the link between the imported and the two autochthonous cases.

    The United Kingdom ex. the northern part of Cyprus
    On 8 September, the United Kingdom reported (through the Early Warning and Response System) three cases of P. vivax malaria in travellers returning from Esentepe, the northern part of Cyprus. Two of the cases were siblings aged twelve years that travelled independently from the third case. The three cases stayed in the northern part of Cyprus for two to three weeks in August and developed symptoms on 29 August. They were laboratory confirmed upon returning to the UK.

    ECDC assessment

    In the EU/EEA countries, 31 966 cases of malaria were reported between 2012 and 2016, corresponding to a yearly average of around 6 400 cases (range: 5 272 cases in 2012 ? 7 147 cases in 2016). Infection occurred in malaria-endemic countries for 99.8% of the cases (importation data available for 31 237 cases). The notification rate between 2012 and 2016 remained stable, from 0.8 (2012-2013) to 1.0 (2014-2016) cases per 100 000 population. In 2016, according to European Surveillance System (TESSy), 12 cases were locally acquired: eight cases in Greece, two in France, one in Spain and one in Lithuania. All these cases are considered to be sporadic cases of introduced malaria or airportacquired infections.

    No sustainable transmission of malaria was reported in the EU/EEA in 2016. Locally acquired cases of malaria have been occurring in Greece since 2009, with the highest numbers reported in 2011. Since 2012, local malaria transmission has been ongoing, but fewer cases were reported. In 2011, ECDC published a rapid risk assessment on the situation in Greece. Nosocomial transmissions of P. falciparum in healthcare settings have been documented in the EU but remain rare events. Healthcare providers should be aware of the risk of nosocomial transmission of malaria and the correct application of standard precautions should be ensured when patients with malaria are hospitalised. The suspicion of nosocomial transmission should trigger an investigation of infection control practices related to transmission of blood-borne pathogens (contact with blood, needle and sharp disposal, intravenous administration of treatment). As mosquito-borne transmission in a healthcare setting is possible, entomological investigations should be conducted when transmission of malaria occurs in such settings and adequate control measures applied.

    The risk for spread of malaria in the EU following these events remains very low.

      Epidemiological update - indigenous Plasmodium falciparum malaria cases in the Apulia region, Italy



      6 Oct 2017

      On 4 October 2017, Italy reported through the Early Warning and Response System (EWRS) the detection of four Plasmodium falciparum malaria cases in the Apulia region. Cases are 21 to 37-year-old men, originally from Africa. All stated that they had been in Italy for more than three months. Dates for onset of symptoms ranged from 20 to 27 September 2017. The cases are agricultural workers in Ginosa and Castellaneta. Malaria vectors such as Anopheles labranchiae and Anopheles superpictus are present in Italy.

      The report of four Plasmodium falciparum malaria cases in Italy without travel history to malaria-endemic countries is unusual. The fact that all the cases had onset of symptoms within a week and all had been in Italy for more than three months suggests an indigenous transmission in Italy resulting from either a ?suitcase? event or an introduced malaria event.

      On 20 September, ECDC published the rapid risk assessment ?Multiple reports of locally-acquired malaria infections in the EU?.

      The conclusions of the rapid risk assessment remain valid. The risk of further spread of malaria in the EU is considered very low. At this time of the year, the risk of further transmission in connection with the cases is considered low. Epidemiological, parasitological and entomological investigations should provide evidence on the source of infection and should support further assessment of the risk for transmission.

      The Italian authorities are investigating this event and ECDC is continuing to monitor the event through epidemic intelligence activities.
