Source: ECDC - 14 Feb. 2013
The latest figures from the Portuguese Ministry of Health indicate an important decrease of the number of notified cases reported since mid-November 2012, week 46 (see the 'Situação em 03/02/2013' update on the Dengue fever page of the Direção-Geral da Saúde website) - as reported in previos post on this blog. However, the outbreak is still on-going with 28 cases reported in 2013 and three cases last week recorded by the local epidemiological surveillance system. This is indicative of an uninterrupted transmission occurring since the start of the outbreak and continuous vector activity. In addition, based on retrospective information on vector surveillance and meteorological data, the seasonal increase of vector activities will likely take place from around May-June 2013.
ECDC advises residents and travellers visiting the island of Madeira to take individual protective measures (like using repellents) to avoid mosquito bites. Dengue is transmitted by a daytime mosquito and consequently protective measures must be applied throughout the day. Travellers experiencing febrile symptoms with severe headache, retro-orbital pain, myalgia, arthralgia and maculo-papular rash within 21 days of visiting Madeira are advised to seek medical advice.
ECDC continues monitoring the situation in collaboration with National and regional (Madeira) public health authorities in Portugal and gathering information on confirmed cases reported by EU/EEA Member States among returning travellers.
