Doctors Without Borders/Médecins Sans Frontières (MSF) is responding to COVID-19 in Puerto Rico by working in collaboration with several local community organizations, to help at-risk groups, including homeless people, people who use drugs, and the elderly. “The network on the island is already so strong” says Yoruba Mitchell, MSF Health Promotion Manager. “So what we did was basically come in and support those existing networks with the skills that we were able to contribute with our experience, working in outbreaks and providing trainings and equipment.” As COVID-19 cases rise in Puerto Rico, MSF has expanded its response on the island, providing primary care consultations in homes and clinics to people with no access to medical services and monitoring the symptoms of COVID-19 patients.
