Causes of Rubella

  • This disease is caused by a pathogen known as the rubella virus.

  • The virus is transmitted from person to person via the respiratory route when the infected person sneezes or coughs.

  • It can also be transmitted when a person comes in direct contact with an infected individual’s respiratory secretions.

  • Furthermore, the disease can also be passed from a pregnant woman to the unborn child via the bloodstream.

  • Once the virus enters the body, it starts replicating in the nasopharynx and lymph nodes.

  • After 5-8 days, it enters the bloodstream and then starts spreading to the rest of the body.

  • The patient is most contagious during the incubation period, which is 7-14 days before the rash appears.

  • Therefore an infect person can spread the disease to other people before realizing he/she is sick.
