Coronavirus disease 2019 (COVID-19) surveillance, in Brazil, initiated shortly after its description, in China. Our aim was to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and additional pathogens in samples from the initial phase of the outbreak in Brazil, from late February to late March. From 707 samples analysed, 29 (4.1%) were SARS-CoV-2 positive. Fever and cough were their most prevalent symptoms. Co-detection of rhinovirus was observed in 2 (6.9%) cases. Additional pathogens were identified in 66.1% of the SARS-CoV-2 negative cases, mainly rhinovirus and influenza A(H1N1)pdm09. Thus, we emphasise the importance of differential diagnosis in COVID-19 suspected cases.
2019 年冠状病毒病（COVID-19）监测在巴西启动于中国对该疾病的描述之后不久。我们的目的是检测巴西疫情初始阶段（2 月下旬至 3 月下旬）样本中的严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）和其他病原体。在分析的 707 个样本中，有 29 个（4.1%）为 SARS-CoV-2 阳性。最常见的症状是发热和咳嗽。在 2 个病例（6.9%）中观察到鼻病毒的共同检测。在 SARS-CoV-2 阴性病例中，66.1%的病例中还发现了其他病原体，主要是鼻病毒和甲型流感病毒（H1N1）pdm09。因此，我们强调在 COVID-19 疑似病例中进行鉴别诊断的重要性。
