During the Science study, some children quickly regained new antibodies to fight off staph infections, influenza and adenoviruses, the family of viruses that cause sore throats and pneumonia.
How does your immune system fight measles?
The characteristic disease features of measles–fever and rash–are associated with the immune response to infection and are coincident with virus clearance. MV-specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
Does the measles virus stay in your system?
The virus stays alive, airborne outside the body of its human host, for up to two hours. For years scientists puzzled over how exactly measles achieves its contagion-in-chief status.

Can measles only infect humans?
The virus is related to several viruses that infect animals, including the Canine Distemper Virus. Primates can be infected in vitro but humans are the only reservoir for the measles virus which, theoretically, could be eradicated from the world.

Why is vit a given for measles?
Pre-existing deficiency appears to worsen infection and vitamin A supplementation has been shown to reduce the risk of death in 6–59 month old children by about 23–30% (20). In the case of pneumonia that is associated with measles, large doses of vitamin A have a clear protective effect (21,22).
What vitamin is given alongside antiviral for measles?
Vitamin A deficiency is a recognised risk factor for severe measles. The World Health Organization (WHO) recommends administration of an oral dose of 200,000 IU (or 100,000 IU in infants) of vitamin A per day for two days to children with measles in areas where vitamin A deficiency may be present.
Is there an antiviral drug for measles?
There is no specific antiviral therapy for measles. Medical care is supportive and to help relieve symptoms and address complications such as bacterial infections.
