In 2015, an Ebola outbreak occurred in Guinea, Liberia, and Sierra Leone. The Centers for Disease Control and Prevention (CDC) later downgraded the Travel Notice for Guinea, Liberia, and Sierra Leone to Level 1, no longer advising against nonessential travel, and no longer recommending that all persons practice enhanced precautions when traveling to these countries.  

Neither the Bureau of Consular Affairs nor U.S. embassies and consulates deal with quarantine issues and cannot prevent a U.S. citizen from being quarantined should local health authorities require it. For questions about quarantine, please visit the CDC website.
