Probe-based metagenomic pathogen detection: advancing laboratory capacity for c...
Ferreira, Rita; Coelho, Luís; Santos, João Dourado; Sobral, Daniel; Isidro, Joana; Mixão, Verónica; Pinto, Miguel; Nunes, Alexandra; Borrego, Maria JoséProbe-based pathogen enrichment, followed by NGS, is a promising tool for complex diagnosis, overcoming traditional challenges of shotgun metagenomics, namely small microbial/human genetic material ratio and demanding computational resources. Here, we assessed the combined detection performance of two Illumina probe-based panels, the Respiratory and the Urinary Pathogen ID panels (RPIP and UPIP), using 99 clini...
An Overview of Monkeypox Virus Detection in Different Clinical Samples and Anal...
Cordeiro, Rita; Pelerito, Ana; de Carvalho, Isabel Lopes; Lopo, Sílvia; Neves, Raquel; Rocha, Raquel; Palminha, Paula; Verdasca, NunoMpox is a zoonotic disease caused by the Monkeypox virus (MPXV), and since May 2022, tens of thousands of cases have been reported in non-endemic countries. We aimed to evaluate the suitability of different sample types for mpox diagnostic and assess the temporal dynamics of viral load. We evaluated 1914 samples from 953 laboratory-confirmed cases. The positivity rate was higher for lesion (91.3%) and rectal sw...
Viral genetic clustering and transmission dynamics of the 2022 mpox outbreak in...
Borges, Vítor; Duque, Mariana Perez; Martins, João Vieira; Vasconcelos, Paula; Ferreira, Rita; Sobral, Daniel; Pelerito, Ana; de Carvalho, Isabel LopesPathogen genome sequencing during epidemics enhances our ability to identify and understand suspected clusters and investigate their relationships. Here, we combine genomic and epidemiological data of the 2022 mpox outbreak to better understand early viral spread, diversification and transmission dynamics. By sequencing 52% of the confirmed cases in Portugal, we identified the mpox virus sublineages with the hi...
World Youth Day 2023 - non-endemic infectious disease surveillance through wast...
Valério, Elisabete; Palminha, Paula; Neves, Raquel; Cadinha, Luis; Ferreira, João Duarte; Correia, Paulo; Medeiros, InêsThe World Youth Day (WYD) is an event that mobilizes millions of people from all over the world. It is an event promoted by the Catholic Church mainly focused on young people and aims to bring together representatives from all Catholic countries. In 2023, WYD was held in Portugal, hosted in Lisbon between August 1st and 6th. Other satellite events prior to WYD were promoted throughout the country. Portimão Muni...

Surto de parotidite epidémica numa escola secundária do concelho de Vila Real d...
Neves, Raquel; Lourenço, Teresa; Ribeiro, Carlos; Palminha, PaulaA parotidite epidémica (“papeira”) é uma doença contagiosa causada por um vírus de RNA, pertencente à família Paramixovírus, género Rubulavirus. O vírus da parotidite epidémica tem apenas um serotipo, mas 12 genótipos diferentes (A, B, C, D, F, G, H, I, J, K, L, N). Em Portugal, a vacina contra a papeira foi introduzida no Plano Nacional de Vacinação (PNV) em 1987 combinada com a vacina do sarampo e rubéola (VA...
Report of simultaneous measles outbreaks in two different health regions in Por...
Augusto, Gonçalo Figueiredo; Silva, Andreia; Pereira, Natália; Fernandes, Teresa; Leça, Ana; Valente, Paula; Calé, Etelvina; Aguiar, Bárbara AndreiaIn Portugal, measles vaccination coverage and population immunity are high, and no endemic measles cases had been reported since 2004. The World Health Organization classified measles as eliminated in the country in 2015 and 2016, based on data from the previous 3 years. However, in a context of increasing incidence in several European countries in 2016 and 2017, Portugal experienced two simultaneous measles ou...

Avaliação Externa da Qualidade em Serologia da Rubéola, PNAEQ (2015-2017)
Correia, Helena; Cardoso, Ana; Pereira, Edna; Ventura, Catarina; Viegas, Sílvia; Vinagre, Elsa; Palminha, Paula; Faria, Ana PaulaA Rubéola é uma infeção viral aguda e contagiosa que pode ser prevenida pela vacinação. A infeção pelo vírus da Rubéola em crianças e adultos provoca sintomas como febre ligeira e exantema. No entanto, a infeção durante a gravidez, especialmente durante o primeiro trimestre, pode provocar aborto, morte fetal, nado-morto, ou crianças com malformações congénitas. Em Portugal, a vacina contra a Rubéola foi introdu...
Challenging measles case definition: three measles outbreaks in three Health Re...
Augusto, Gonçalo Figueiredo; Cruz, Diogo; Silva, Andreia; Pereira, Natália; Aguiar, Bárbara; Leça, Ana; Serrada, Elisabete; Valente, PaulaWe report three simultaneous measles outbreaks with 112 confirmed cases in three Health Regions of Portugal, from February to April 2018. The mean age of cases was 30 years, 79% worked in a healthcare setting and 87% were vaccinated. Genotype B3 was identified in 84 cases from the three outbreaks. Primary cases in each outbreak were imported. Several cases presented with modified measles, highlighting the impor...
