First case of Oropouche fever detected in the international border region of the Colombian Amazon: clinical characteristics and molecular diagnosis.

OBJECTIVES: We report the first case of Oropouche fever detected in the border region of Colombia. METHODS: Using a multiplex real-time polymerase chain reaction (PCR), genetic sequencing and clinical characteristics during the dengue epidemic in 2019, a total of 175 samples were analysed, from cases notified to the system epidemiological surveillance such as dengue. FINDINGS: The Oropouche virus (OROV) isolate from Leticia belongs to lineage 2 according to both M and S genome segments maximum likelihood (ML) analysis, shares a common ancestor with samples obtained in Esmeraldas, Ecuador and Turbaco, Colombia. The patient: a woman resident in the border neighbourhood of the municipality of Leticia had the following symptoms: fever, headache, retro-orbital pain and myalgias. MAIN CONCLUSION: This cross-border surveillance can be useful to give an alert about the entry or exit of arboviruses circulation in the region, which are often underreported in public health surveillance systems.

Implementing a provisional overarching intervention for COVID-19 monitoring and control in the Brazil-Colombia-Peru frontier.

Introduction: he challenge was to provide comprehensive health resources to a remote and underserved population living in the Brazil-Colombia-Peru border, amid the most disruptive global crisis of the century. Methods: In August 2021, Fundação Oswaldo Cruz Amazonia (FIOCRUZ Amazônia) and partner collaborators implemented an overarching provisional program for SARS-CoV-2 detection and lineages characterization, training of laboratory personnel and healthcare providers, donation of diagnostic supplies and personal protective equipment, and COVID-19 vaccination. The expedition was conducted at the Port of Tabatinga, a busy terminal with an intense flux of people arriving and departing in boats of all sizes, located in the Amazon River basin. Local government, non-profit organizations, private companies, and other stakeholders supported the intervention. Results: The expedition was accomplished in a convergence point, where migrant workers, traders, army personnel, people living in urban areas, and people from small villages living in riversides and indigenous territories are in close and frequent contact, with widespread cross-border movement. Using a boat as a provisional lab and storage facility, the intervention provided clinical and laboratory monitoring for 891 participants; vaccination for 536 individuals; personal protective equipment for 200 healthcare providers; diagnostic supplies for 1,000 COVID-19 rapid tests; training for 42 community health agents on personal protection, rapid test execution, and pulse oximeter management; and hands-on training for four lab technicians on molecular diagnosis. Discussion: Our experience demonstrates that multilateral initiatives can counterweigh the scarcity of health resources in underserved regions. Moreover, provisional programs can have a long-lasting effect if investments are also provided for local capacity building.

Zika epidemic and microcephaly in Brazil: Challenges for access to health care and promotion in three epidemic areas.

Since 2015 Brazil has experienced the social repercussions of the Zika virus epidemic, thus raising a debate about: difficulties of diagnosis; healthcare access for children with Zika Congenital Syndrome (ZCS); the search for benefits by affected families; social and gender inequalities; and a discussion on reproductive rights, among others. The objective of this article is to analyse access to specialized health services for the care of children born with ZCS in three North-eastern states of Brazil. This is an exploratory cross-sectional study which analyses recorded cases of microcephaly at the municipal level between 2015 and 2017. Most of the cases of ZCS were concentrated on the Northeast coast. Rio Grande do Norte and Paraiba had the highest incidence of microcephaly in the study period. The states of Bahia, Paraiba and Rio Grande do Norte were selected for their high incidence of microcephaly due to the Zika Virus. Socio-territorial vulnerability was stratified using access to microcephaly diagnosis and treatment indicators. The specialized care network was mapped according to State Health Secretaries Protocols. A threshold radius of 100 km was stablished as the maximum distance from municipalities centroids to specialised health care for children with microcephaly. Prenatal coverage was satisfactory in most of the study area, although availability of ultrasound equipment was uneven within states and health regions. Western Bahia had the lowest coverage of ultrasound equipment and lacked health rehabilitation services. ZCS's specialized health services were spread out over large areas, some of which were outside the affected patients' home municipalities, so displacements were expensive and very time consuming, representing an extra burden for the affected families. This study is the first to address accessibility of children with microcephaly to specialised health care services and points to the urgent need to expand coverage of these services in Brazil, especially in the northeastern states, which are most affected by the epidemic.

Deep Sequencing Reveals Occult Mansonellosis Coinfections in Residents From the Brazilian Amazon Village of São Gabriel da Cachoeira.

Mansonella ozzardi and Mansonella perstans infections both cause mansonellosis but are usually treated differently. Using a real-time polymerase chain reaction assay and deep sequencing, we reveal the presence of mansonellosis coinfections that were undetectable by standard diagnostic methods. Our results confirm mansonellosis coinfections and have important implications for the disease's treatment and diagnosis.

O vírus do Dengue é transmitido naturalmente pelo mosquito Aedes aegypti, seu vetor principal no mundo, e em algumas regiões, também pelo mosquito Ae. albopictus. Segundo a OMS, o Dengue tornou-se a mais importante arbovirose transmitida por vetores no mundo, causa anualmente cerca de 390 milhões de infecções no mundo, e põe em risco uma população de cerca de 2,5 a 3 bilhões de pessoas. O Dengue é endêmico de regiões tropicais como o sudeste asiático, sul do Pacífico, África Oriental, Caribe e América Latina. Na Colômbia, o primeiro surto de Dengue na cidade de Letícia (Amazonas), fronteira com o Brasil, foi em 2011 com 540 casos notificados de Dengue, bem como em 2012, foram notificados 533 casos. No Brasil, Tabatinga (Amazonas, Brasil), município na fronteira com a Colômbia, notificou 418 casos da Dengue em 2012. Em 1996, Ae. albopictus foi registrado na cidade de Tabatinga, mas foi rapidamente erradicado. O primeiro registro de Ae. albopictus na Colômbia foi no bairro de La Esperanza (Letícia, Amazonas) em 1998. por outro lado, em Tabatinga Ae. aegypti foi encontrado em 2008 no porto civil, e na cidade de Letícia em 2009 no bairro de La Union. Se estudou e avaliou a distribuição espaço-temporal dos criadouros positivos e as populações de Ae. albopictus e Ae. aegypti e sua associação com os fatores climáticos e os casos de Dengue na área urbana do município de Letícia-Amazonas (Colômbia)...
