Rood Western Governor’s University Introduction to Measles Measles is a highly contagious, infectious disease caused by a morbillivirus in the paramyxovirus family classification, who’s only known host is humans (Kutty, MD, P., 2014). This means that only humans can carry and transfer the virus and are the only organism that can get sick from it. Measles successfully infects ninety percent of all exposed persons who are susceptible, meaning without either natural or vaccine originated immunity (Merck Sharp & Dohme Corp., 2013).

Of course, as with most viral infections, the infected person can spread the virus before having symptoms. There is currently no medical treatment to cure any virus. There are medications that can hinder viral reproduction/replication; however, these medications have been developed for only a select few virus types. For most viral infections, only supportive care like symptom treatment and complication management, is available and is given while the viral illness runs its natural course. The hope is that supportive care allows our own immune system the time needed to fight off the virus. Initial symptoms of measles infection are high fevers, fatigue, cough, and inflammation of the mucous membranes in the eye leading to drainage (Centers for Disease Control and Prevention, 2012). One “tell-tale” symptom is a characteristic rash that looks like multiple small bumps on flat reddened skin called a maculopapular rash, appearing first on the face then propagates cephalocaudally, or toward the extremities (Centers for Disease
