Der Internist
-
Internists should expect to be the first contact for patients with rare, but highly contagious, life-threatening illnesses. Although certainly not encountered often, it is associated with significant consequences. Thus, physicians should be familiar with viral hemorrhagic fevers: filoviruses cause Ebola and Marburg fever, arenaviruses cause Lassa fever and South American hemorrhagic fevers, and the bunyaviruses cause among others Crimean-Congo hemorrhagic fever. Furthermore, physicians should be familiar with highly contagious respiratory infections, such as hantavirus pulmonary syndrome, pneumonic plague, and Middle East respiratory syndrome (MERS).
