👉 Rubella is a viral infection characterized by fever, rash, and cough in infants. It is caused by rubella virus, which is transmitted through respiratory droplets from infected mothers during pregnancy or breastfeeding. This virus can also cause congenital rubella syndrome in babies born to mothers with the virus. Rubella is often associated with the flu-like symptoms of measles, so it's important for parents to monitor their child's health closely and seek medical advice if they suspect an infection.
