Abstract(s)
O vírus Zika (Flavivirus) é um arbovírus transmitido sobretudo por mosquitos,
mas também, por transmissão materno-fetal e sexual. Existem evidências
que as infeções por vírus Zika podem estar associadas à síndrome
de Guillian-Barré e a casos congénitos de microcefalia e outras malformações
do sistema nervoso central. As infeções por vírus Zika, Dengue e Chikungunya
partilham, atualmente, os mosquitos vetores, a sintomatologia
e a distribuição geográfica. O Centro de Estudos de Vetores e Doenças
Infeciosas do Instituto Nacional de Saúde Doutor Ricardo Jorge no seu
Laboratório Nacional de Referência de Vírus Transmitidos por Vetores tem
desenvolvido o diagnóstico e estudos epidemiológicos de vírus transmitidos
por artrópodes desde o princípio dos anos 90. O diagnóstico de Zika
foi desenvolvido e padronizado em 2007. O laboratório desenvolveu testes
de diagnóstico molecular e serológico tendo identificado vários casos de
importação para o território português e feito o diagnóstico diferencial com
Dengue e Chikungunya e o despiste de infeção em grávidas e em casos de
transmissão sexual.
Zika virus (Flavivirus) is a mosquito borne arbovirus, but maternofetal and sexual transmission were also described. There is evidence that Zika virus infections may be associated with Guillain-Barré syndrome and congenital cases of microcephaly and other malformations of the central nervous system. Zika, Dengue and Chikungunya virus infections share currently the same mosquito vectors, the signs and symptoms of the illness and the same and geographical distribution. The Center for Vectors and Infectious Diseases Research from the National Institute of Health Doutor Ricardo Jorge in their National Reference Laboratory for Vector Borne Virus has developed diagnostic methods and epidemiological studies of arboviruses since the beginning of the 90s. The Zika diagnosis was developed and standardized in 2007. The Laboratory developed molecular and serological diagnostic tests and have identified several imported cases of Zika infections into Portuguese territory and performed the differential diagnosis with Dengue and Chikungunya and screening for infection in pregnant women and in suspected cases of sexual transmission.
