As of 14 September, fourteen autochthonous confirmed cases of chikungunya have been diagnosed in Italy, six in Rome and eight in the coastal area of Anzio (Lazio Region).
There are additional cases being investigated.
The date of onset of symptoms of the first case was on 5 August 2017. The dates of onset of the latest cases are between 25 August and 7 September 2017.
WHO risk assessment
There is a risk for further transmission. This is due to:Aedes albopictus being established throughout the Mediterranean basin;this vector having demonstrated the capacity to sustain outbreaks of chikungunya in the past; andthe area of the current case being highly populated and touristic particularly in summer months.The disease mostly occurs in Africa, Asia, Americas and the Indian subcontinent. In 2007, transmission was reported for the first time in Europe, in the Emilia Romagna region of north-eastern Italy.
There were 217 laboratory confirmed cases during this outbreak and it demonstrated that mosquito-borne outbreaks by Aedes albopictus are possible in Europe. Currently, there is another ongoing autochthonous outbreak in Var Department that started in early August 2017.
WHO advice
Personal protection
Basic precautions should be taken by people within and travelling to this area of Italy. These include wearing long sleeves and pants, use of repellents, and ensuring rooms are fitted with screens to prevent mosquitoes from entering.Clothing which minimizes skin exposure to the day-biting vectors is advised. Repellents can be applied to exposed skin or to clothing in strict accordance with product label instructions. Repellents should contain DEET, IR3535, or Icaridin. People should sleep under a mosquito bed net and use air conditioning or window screens to prevent mosquito bites. Mosquito coils or other insecticide vaporizers may also reduce indoor biting.
About chikungunya
Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash. Joint pain is often debilitating and can vary in duration. Hence the virus can cause acute, subacute or chronic disease. There is no cure for the disease and treatment is focused on relieving the symptoms. The proximity of mosquito breeding sites to human habitation is a significant risk factor for chikungunya.
