Measles is a disease caused by

Measles, also known as rubeola, is a highly contagious infectious disease caused by a virus . Specifically, the causative agent is the measles virus, which is a single-stranded, negative-sense, enveloped RNA virus [5]. It belongs to the genus Morbillivirus within the Paramyxoviridae family [4]. Humans are the only natural hosts for this virus, and it is transmitted through direct contact with infectious droplets or via airborne spread when an infected person coughs or sneezes [5]. Unlike bacterial infections, which can be treated with antibiotics, viral diseases like measles do not respond to such medications [4]. The disease is characterized by symptoms such as fever, cough, coryza, conjunctivitis, and a distinctive maculopapular rash . Prevention is primarily achieved through the live attenuated measles vaccine [4].
