A 37-year-old man from the Democratic Republic of Congo tested positive for meningococcal meningitis on Saturday night (30), but suspicion of Ebola virus infection has not been ruled out. According to the São Paulo State Health Department, the Adolfo Lutz Institute confirmed the presence of Neisseria meningitidis bacteria, which causes meningitis, while specific Ebola tests remain ongoing.

"foi confirmado que o homem que foi classificado como suspeito do vírus Ebola teve o resultado positivo para a bactéria da meningite meningocócica"

A Gazeta

"O paciente, um homem de 37 anos de procedência da República Democrática do Congo — país com áreas de transmissão da doença pelo vírus Ebola, e viagem recente ao território — apresentou sintomas como febre, preenchendo a definição de caso suspeito."

Oglobo

"Até o momento, não foi possível confirmar a província de origem do paciente na República Democrática do Congo, informação importante para a avaliação do risco epidemiológico."

The patient was first treated at an Emergency Care Unit (UPA), where he presented high fever and inconclusive malaria tests, before being transferred to the Emílio Ribas Institute of Infectology on Saturday. According to the Ministry of Health, he arrived at the institute in serious condition, with diarrhea, disorientation and rapid clinical deterioration, requiring immediate intubation.

"Ele chegou em estado grave à unidade de referência, com diarreia, desorientação e rápida piora clínica, sendo necessária intubação."

The investigation was initiated after identifying clinical and epidemiological criteria compatible with a suspected viral hemorrhagic fever case. The patient had recent travel to the Democratic Republic of Congo, a country facing an outbreak of the Bundibugyo strain of Ebola virus since May 15 — classified by the World Health Organization as a Public Health Emergency of International Concern.

"A investigação ocorre em meio à preocupação internacional com o avanço do surto de ebola causado pela cepa Bundibugyo na República Democrática do Congo. Em 16 de maio, a Organização Mundial da Saúde classificou o evento como Emergência de Saúde Pública de Importância Internacional"

Despite the ongoing investigation, health authorities assess that the risk of Ebola introduction in Brazil remains very low. Among the factors considered are the historical absence of autochthonous transmission in the South American continent, the lack of direct flights between the affected region and South America, and the need for direct contact with body fluids from symptomatic people for disease transmission.

A Gazeta

"Entre os fatores considerados estão a ausência histórica de transmissão autóctone (quando uma doença é contraída e transmitida dentro da mesma localidade onde o indivíduo reside, sem que ele tenha viajado recentemente para áreas endêmicas) no continente sul-americano, a inexistência de voos diretos entre a região afetada e a América do Sul e a forma de transmissão da doença, que exige contato direto com sangue, secreções, fluidos corporais ou tecidos de pessoas sintomáticas infectadas"
