Human case of West Nile neuroinvasive disease in Portugal, summer 2015.

A case of West Nile virus (WNV) infection was reported in the Algarve region, Portugal, in the first week of September 2015. WNV is known to circulate in Portugal, with occasional reports in horses and birds (2004 to 2011) and very sporadically human cases (in 2004 and in 2010). Here we present the clinical and laboratory aspects related to the first human case of West Nile neuroinvasive disease reported in Portugal.

[Toscana virus in the Portuguese population: serosurvey and clinical cases].

Toscana virus (Phlebovirus genus, Bunyaviridae family) is a neurotropic virus which circulates in the Mediterranean Basin. Although Portugal has been the second country where its presence was reported, the existence of this virus in our country has been referred only sporadically, and there is a lack of knowledge regarding the prevalence of antibodies in the population. Thus, the objective of this study was to analyse the prevalence of antibodies anti-Toscana virus in the human population in our country.

Boutonneuse fever and climate variability.

Researchers have long appreciated the role of climate in vector-borne diseases, including the resurgence of boutonneuse fever (BF). Portugal usually is classified as having temperate Mediterranean climate. In this new century, in analyzing the data from the Meteorology Institute, this pattern has changed and an accentuated variability in climate is being observed.
