All are true about congenital rubella syndrome, except-
**Core Concept**
Congenital rubella syndrome (CRS) occurs when the rubella virus infects a pregnant woman during the first trimester, causing a range of serious birth defects. The **rubella virus** targets developing fetal tissues, leading to abnormalities in multiple organ systems. This condition is a significant concern in areas with low vaccination rates.
**Why the Correct Answer is Right**
Since the correct answer options are not provided, let's discuss the general aspects of CRS. The syndrome can lead to **deafness**, **cataracts**, **congenital heart disease**, and **neurodevelopmental delays**. The virus disrupts normal fetal development by damaging the developing organs.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, we can't address it directly, but typically, incorrect options might include statements about the timing of infection or the symptoms that are not characteristic of CRS.
**Option B:** Similarly, without specifics, we might expect an incorrect statement about the vaccine's role or the syndrome's manifestations.
**Option C:** This could potentially be about the wrong demographic being at risk or an incorrect association with another condition.
**Option D:** Might claim a false complication or an unlikely manifestation of CRS.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **rubella vaccination** is highly effective in preventing CRS, emphasizing the importance of vaccination programs. Ensuring high vaccination rates in the population is crucial for preventing outbreaks and, consequently, CRS cases.
