In December 2019 a new disease called COVID-19 emerged in China, this disease spreads quickly and on January 30, 2020, it was declared the Public Health Emergency of International Importance. On March 11, 2020 the World Health Organization featured COVID-19 as pandemic [1]. Many women who breastfeed and have been infected with covid-19 are the target of a common doubt. Can breastfeeding put the child’s life at risk? We have few reported cases where breast milk is studied to discover the possibility of transmission of SARS-COV2 through breastfeeding. For this reason, we decided to share this case study. In this case, the patient is a mother and breastfeeding a child of 2 years and 5 months, does not report previous illnesses or comorbidities, exposed to contact with people contaminated with COVID-19 daily. The patient reports that starts with symptoms of sore throat, dry cough, and a few days later, she also had mild dyspnea and fatigue. A chest Computed Tomography image scan was performed and the result was within normal standards, but the RT-PCR swab test performed in the sequence resulted positive, detected for SARS-COV2. This patient is placed in isolation, evolved with COVID-19 Mild Disease, according to guideline from the Centers for Disease Control and Prevention-CDC [2]. During the isolation period, breast milk was collected. This material was sent for study, and performed RT-PCR tests (a real-time reverse transcription polymerase chain reaction RT-PCR, test for the qualitative detection of nucleic acid from SARS-CoV-2) in breast milk simple was not detected the presence of SARS-COV2.
