There has been no evolution of reported cases of Dengue Fever in local or visiting tourists (exported cases) population since last week´s report as the Portuguese health authorities announced that they will cease to publish regular updates regarding the number of dengue cases in Madeira, even after the ECDC in their report on 13 December 2012 alerted to the expected increase in cases until the end of the mosquito season in January 2013 and increased population over the Christmas and New Year season by visiting tourists as Madeira is a popular holiday destination.

ECDC maintain the following statement regarding travel to and from Madeira, as well as suggesting preventative measures form getting bitten by mosquito.

Comments and Analysis by ZINO

As reported in the ECDC report 13 December 2012, although there is a reduction in number of new cases, new cases are still being reported:

The updated figures indicate that the outbreak has peaked and despite an important decrease of the number of notified cases reported, the outbreak is still on-going. Therefore, more cases among the island’s population as well as among returning tourists should be expected.
The main breeding period of the dengue mosquito vector, Aedes aegypti, will continue until the beginning of next year and coincides with a peak in the number of visitors to the island over the Christmas holidays.

There was fanfare that the regional authorities including the "Tourism Board" and "Regional Health Authorities" as well as the "Chamber of Commerce" and "enterprises" were setting up a commission to monitor this situation. We very much hope that monitoring will occur so that when there is the next Aedes aegypti mosquito surge, adequate measures can be taken in a timely fashion to prevent large mosquito populations and consequent dengue transmission.

If you would be interested in participating in a monitoring programme, please contact us.

WHO - Dengue global Map, areas of risk

6/12/2012

Many holiday destinations are Dengue fever zones, as identified by the World Health Organization. recent outbreaks in Europe raise the questions:
- do holiday makers understand that there are various strains of Dengue fever, from a mild strain which causes flu like symptoms to hemorrhagic fever
- most dengue cases have a possitive evolution with no medical problems
- that preventative measures such as the use of mosquito repellent, long sleeve shirts and trousers, mosquito nets are usually enough to prevent getting bitten
- accommodation and leisure facilities which undertake mosquito control measures also contribute to the preventative measures, as reduce the mosquito population

We would very much like to know your opinion, as a holiday maker.
