The most infectious period is usually 1–5 days after the appearance of the rash. When a woman is infected with the rubella virus early in pregnancy, she has a 90% chance of passing the virus on to her fetus.
8 sie 2023 · Once the diagnosis of rubella is confirmed, the patient should be promptly isolated for at least 7 days after onset of the rash. Because rubella is transmitted primarily by inhalation of virus-laden airborne droplets, standard and droplet precautions are recommended for hospitalized patients.
1 gru 2023 · The risk of transmission is 10–30%, but varies with the immunisation rate of the population, and infectivity is high in those susceptible. The period of infectivity is seven days before to six days after the onset of rash and the incubation period is 13–20 days.
2 kwi 2022 · Rubella virus is transmitted through respiratory droplets and direct contact. 25–50% of people infected with rubella virus are asymptomatic. Clinical disease often results in mild, self-limited illness characterised by fever, a generalised erythematous maculopapular rash, and lymphadenopathy.

26 kwi 2021 · The RUBV E1 protein mediates both virus receptor binding and virus membrane fusion (16, 25). E1 is a type I membrane protein with a predicted molecular weight of 51 kDa; posttranslational modifications result in a molecular weight of ∼58 kDa (Fig. 4B) (16, 25, 27, 52).
The average incubation period of rubella virus is 17 days, with a range of 12 to 23 days. People infected with rubella are most contagious when the rash is erupting. But they can be contagious from 7 days before to 7 days after the rash appears.
