Innovation in Infectious Disease Care Wide shot of the bioncontainment unit room with monitors.

The Johns Hopkins biocontainment unit (BCU) is a state-of-the art facility designed to care for adult and pediatric patients affected by high-consequence infectious diseases such as COVID-19, Ebola, smallpox, SARS, viral hemorrhagic fevers and other emerging special pathogens. The unit is a multidisciplinary collaboration of experts from across Johns Hopkins and around the world.

Led by Lisa Maragakis and Brian Garibaldi, the BCU is staffed by self-selected health care workers who train extensively to maintain the BCU’s high-level isolation precautions, including intensive infection control measures like robust personal protective equipment donning and doffing procedures. The unit can provide care for up to four patients in an environment that ensures the safety of patients, their families, health care workers and the community at large. When not active for patient care, the BCU serves as a site for research and training for high-consequence pathogens and clinical care.

Stories of Care at the BCU

Recovering from COVID-19

Members of the Biocontainment Unit, including Dr. Brian Garibaldi, helped treat Gerry and Georgene Stephens.

Hope and Care for Patients with COVID-19 Through Point-of-Care Ultrasound.

During the COVID-19 pandemic, point-of-care ultrasound (POCUS) has become crucial in diagnosing and assessing patients with COVID-19 when traditional ways of evaluating patients, such as using a stethoscope, have become limited because providers must wear personal protective equipment to prevent the spread of COVID-19.
