If cases became infectious at the onset of symptoms, it may be difficult to isolate the infected individuals as they will already be infectious to others by the time they are isolated.</p>\n<p>You may find <a href\="http\://open.lshtm.ac.uk/mod/page/view.php?id\=214">1.9 The logic behind isolation\: incubation, latent and infectious periods</a> useful.</p>

If Kaci had become infected while in Sierra Leone, in which theoretical scenario could she have transmitted Ebola to others in the US?</span></p>{
