Detection of Hyalomma rufipes in a recently arrived asylum seeker to the EU
Copyright © 2020. Published by Elsevier GmbH..
The importation of novel tick species to Europe and the emergence of tick-borne diseases have been of rising concern over the last decades. In May 2019, a total of 349 asylum seekers arrived in Malta by boat. Public health syndromic surveillance was conducted on all migrant boat arrivals. The incidental finding of a tick with anomalous morphology in a newly arrived migrant in Malta prompted an epidemiological investigation. Morphological identification of the tick followed by species identification using keys specific to North Africa was conducted and molecular testing for Crimean Congo haemorrhagic fever virus (CCHFV) was performed. Detailed interview and clinical examination of the case were conducted on arrival and follow-up interviews were undertaken 1- and 4-weeks post-arrival. A Hyalomma rufipes tick was identified on the chest of a 28-year-old male from Sudan. The patient reported malaise and headache on arrival. No further symptoms were reported during follow-up. There was no evidence of previous CCHFV infection or the presence of other ticks or pathogens on the patient. The investigation revealed that the H. rufipes tick had likely been acquired in Libya. This is the first report of the presence of a H. rufipes tick, the main vector for CCHFV, on a recently arrived migrant in Europe. This event highlights the importance of increasing awareness on the risk of tick-borne infections among recently arrived migrants in the Mediterranean countries and the need to consider tick screening as part of the health screening offered in the EU.
