HELLO DEAR I understand your concern, dear scarlet fever is caused by bacteria from the streptococcus group, and there s no evidence that catching scarlet fever during your pregnancy will put your baby at risk. However, if pregnant women infected when she give birth , there is a risk to the baby may also become infected . Pregnant women who have been diagnosed with scarlet fever will be treated with antibiotics during labour. In rare circumstances, strep bacteria can cause severe and life-threatening infections, particularly in women who have recently given birth. This happens when the bacteria that causes sore throat are spread to the genital area. It s important that women who have recently given birth wash their hands before and after going to the toilet or changing sanitary pads. THANKS
