Infection in pregnancy

Chicken pox – only 2% of infections age > 20yrs 3% risk of fetal damage in first 20/52

If mum’s rash develops 1/52 before delivery or to 4/52 after

baby can get sever infection needs protection

No risk between 20/52 and term

If no history of cp check varicella antibodies

If non immune needs VZ Ig no later than 10 days from exposure

Infections in pregmnancy

Rubella – 2-10/52 90% chance of featal damage Toxoplasma gondii 89% adults not immune If fetus infected 10% chance of fetal damage Avoid kittens particularly litter trays Eat well cooked meat Wash vegetables Listeria – soft cheeses, pate. Cookchill foods
