Further to Current note 51/3602 (at http://www.hps.scot.nhs.uk/ewr/redirect.aspx?id=75569), 14 autochthonous cases of chikungunya have been confirmed , six in Rome and eight in the coastal area of Anzio (Lazio region). Additional cases are being investigated. The date of onset of symptoms of the first case was 5 August 2017. The dates of onset of the latest cases are between 25 August and 7 September 2017.
This is the second chikungunya outbreak in Italy. In 2007, 217 confirmed cases were reported in the Emilia Romagna region in the north-east of the country.
According to the World Health Organization (WHO), there is a risk of further transmission of chikungunya, due to the presence of the Aedes albopictus mosquito in the Mediterranean basin and its ability to sustain chikungunya outbreaks. The risk is also due to the affected area being highly populated, particularly in the summer months.
