what social and environmental factors are affecting the spreading of Measles mumps and rubella?

Answer 1

Human beings are the only vector. The virus is not found in the environment. It spreads by droplet infection. Immunization is the only way to prevent the spread of this disease. Measles is one of the leading causes of under- five mortality and morbidity in developing countries. Immunity is transferred from a mother to her baby , lasting for about 6 months.
