All around the world, acutely ill and injured people seek care every day. Frontline providers manage children and adults with medical, surgical and obstetric emergencies, including injuries and infections, heart attacks and strokes, asthma and acute complications of pregnancy. Prioritising an integrated approach to early recognition and resuscitation reduces the impact of all of these conditions. WHO’s Clinical Services and Systems team is dedicated to strengthening the emergency care systems that serve as the first point of contact with the health system for so much of the world, and to supporting the development of quality, timely emergency care accessible to all.
