Which virus is responsible for causing measles?

Measles is caused by the paramyxovirus, a member of the Paramyxoviridae family. This virus is a single-stranded RNA virus that is known for its characteristic ability to cause respiratory infections and its high transmissibility. Measles virus specifically targets the respiratory epithelium and then spreads throughout the body, leading to the classic symptoms associated with the disease, such as high fever, cough, runny nose, and a unique rash. The vaccine for measles is part of the MMR (measles, mumps, and rubella) vaccination program, which has been effective in controlling and reducing the incidence of measles in vaccinated populations. Understanding that measles is linked to the paramyxovirus helps in recognizing its prevention and treatment strategies as well as its potential complications.
