Cause of Musles-
Measles is caused by the measles virus, a single-stranded, negative-sense, enveloped RNA virus of the genus Morbilli-virus within the family Paramyxoviridae. The virus was first isolated in 1954 by Nobel Laureate John F. Enders and Thomas Peebles, who were careful to point out that the isolations were made from patients who had Koplik's spots.[19] Humans are the natural hosts of the virus; no other animal reservoirs are known to exist. This highly contagious virus is spread by coughing and sneezing via close personal contact or direct contact with secretions.
Risk factors for measles virus infection include the following:
Children with immunodeficiency due to HIV or AIDS,leukemia,alkylating agents, or corticosteroid therapy, regardless of immunization statu
Travel to areas where measles is endemic or contact with travelers to endemic areas
Infants who lose passive antibody before the age of routine immunization
Risk factors for severe measles and its complications include the following:
Malnutrition
Underlying immunodeficiency
Pregnancy
Vitamin A deficiency
