According to the regional (IASAUDE) and national (DGS) health authorities, although Madeira has a resident Aedes aegypti mosquito population, there have been no reports of Zika virus in Madeira, with the only cases reported being imported cases.

Jaime Nina, virologist from the national institute of higiene and tropical medicine (Instituto de Higiene e Medicina Tropical) suggests in an article in the regional news paper Diário de Noticias on 29 January 2016 that it would be a good time to try and eradicate Aedes from Madeira. The expected and normal increase in vector mosquito activity in September could be an issue.

Ana Nunes from IASAUDE confirms that:

• Madeira maintains a network of 193 traps to monitor the population of Aedes mosquito
  
• none of the Zika cases reported in Portugal were in Madeira
  
• that the best practices as recommended both by national DGS and international CDC are in place, including educating the population and implementing preventative measures.

Latim America is currently the focus point of the Zika virus outrbreak, transmitted by the vector mosquito species Aedes aegypti and Ae. albopictus with European member states, especially those with resident Aedes mosquito species, showing concern with regard of the potential autochthonous cases of virus infection transmitted by Aedes (Dengue, Chikungunya  and Zika).

Risk Risk Risk of Zika virus importantion and transmission in continental EU
In ECDC´s the "Rapid Risk Assesment" report of 21 January 2016, 

Travel-associated cases of Zika virus infections have been reported in the EU in the past . However, EU Member States are not required to report Zika virus infections to ECDC and the data do not reflect the true number of cases diagnosed in the EU/EEA. As the Zika virus epidemic continues to spread in the Americas and Caribbean, and the awareness of the risk of infection increases among clinicians and travellers, the number of reported travel-related Zika virus infections is expected to increase in the EU. As an example, the Netherlands recently reported six cases returning from Suriname.

Onward transmission from imported cases within the continental EU is possible because Aedes albopictus is a competent vector for the transmission of Zika virus, even though this has not yet been confirmed for European mosquito populations. The risk of transmission of Zika virus infection is extremely low in the EU during winter season as the climatic conditions are not suitable for the activity of Aedes albopictus mosquito. The capacity of European populations of Aedes albopictus to transmit Zika virus is not known but is anticipated and should be assessed.

Other EU Outermost Regions (OMRs) and Overseas Countries and Territories (OCTs) on other continents where mosquito vectors are present such as La Réunion and Madeira are at risk of establishment of local transmission should the virus be introduced. Madeira is of concern because of the close relationship with Brazil and Venezuela where Zika virus is currently circulating, the presence of Aedes aegypti, and the 2012 dengue epidemic which demonstrated the favourable conditions for vector-borne outbreaks.
