Abstract(s)
A Rede de Vigilância de Vetores (REVIVE) resulta da colaboração entre
instituições do Ministério da Saúde (Direção-Geral da Saúde, Administrações
Regionais de Saúde, Instituto dos Assuntos Sociais e da Saúde
da Madeira, Direção Regional de Saúde dos Açores e Instituto Nacional
de Saúde Doutor Ricardo Jorge). A Rede divide-se em duas vertentes,
REVIVE-mosquitos e REVIVE-carraças. Neste artigo apresentam-se, de
forma resumida, os resultados obtidos em 2019 no âmbito do REVIVE-
-carraças. Este programa, que existe há nove anos, tem como principais
objetivos monitorizar a atividade de artrópodes hematófagos; caracterizar
as espécies e sua ocorrência sazonal; identificar agentes patogénicos
importantes em saúde pública, a densidade dos vetores, o nível de
infeção e monitorizar a introdução de espécies exóticas. Das atividades
desenvolvidas em 2019, destaca-se: a participação das cinco Administrações
Regionais de Saúde que realizaram colheitas de carraças em
166 concelhos; nos 2409 ixodídeos colhidos não foi identificada a presença
de espécies exóticas; em 982 carraças foi pesquisada a presença
de borrélias e rickettsias, tendo sido observada a prevalência média
de 2% e 22%, respetivamente, sobretudo em carraças colhidas a parasitar
humanos. O REVIVE-carraças continua a contribuir para um conhecimento
sistemático da fauna de ixodídeos de Portugal, e do seu potencial
papel de vetor, constituindo uma componente dos programas de vigilância
epidemiológica indispensável à avaliação do risco de transmissão de
doenças potencialmente graves.
The Vector Surveillance Network (REVIVE) results from the collaboration between institutions of the Ministry of Health (Directorate-General for Health, Regional Health Administrations, Institute of Social Affairs and Health of Madeira, Regional Directorate of Health of the Azores and National Institute of Health Dr Ricardo Jorge). It is divided into two areas, REVIVE-mosquitoes and REVIVE-ticks. In this article, the results obtained in 2019 in the context of REVIVE-ticks are summarized. This program, which has completed nine years, aims to monitor the activity of blood-sucking arthropods; to characterize the species and their seasonal occurrence; to identify important pathogens in public health, the density of the vectors, the level of infection and monitor the introduction of exotic species. Among the activities developed in 2019 stands out: the participation of the five Regional Health Administrations that carried out tick harvesting in 166 municipalities; in the 2409 ixodids collected, the presence of exotic species was not identified; in 982 ticks, the presence of borrelias and rickettsiae was investigated, with an average prevalence of 2% and 22%, respectively, especially in ticks harvested when parasitizing humans. REVIVE-ticks continues to contribute to a systematic knowledge of the fauna of ixodids in Portugal, and its potential role as a vector, constituting a component of epidemiological surveillance programs indispensable to assess the risk of transmission of potentially serious diseases.
