Chickenpox: 8 answers to mothers' doubts
Dr. Marta Luisa Ciofi degli Atti, epidemiologist of the Bambin Gesù pediatric hospital in the city, answers.
1. What can be done to relieve itching?
If the itching is very annoying, especially at night, an antihistamine can be given to the baby before bedtime. In addition to soothing the itch, it prevents bacterial infections that occur when babies scratch a lot.
2. Do alternative itch remedies work?
In the pharmacy you can find creams and powders that give some relief. The only recommendation with powders is to pay attention to inhalation: especially if the children are small, they could cause respiratory problems.
3. How to dress the baby when he has pustules?
Clothing should be light, white cotton and comfortable. Another tip is to keep it in a not too hot environment.
4. Can the bath be done?
Keeping the skin clean and well hydrated is important. So yes to the bath, which however must be short and done in lukewarm water. There are also no contraindications for washing your hair.
5. Does the sun hurt?
As long as there are scabs, the child must absolutely not expose himself to the sun. And even after, when the scabs are gone, but the skin still has small lesions, you need to be very careful. The best thing is to protect the little one with physical screen sunscreens (they are the white-paste ones that have a strong covering power) and keep the child as sheltered as possible with long-sleeved shirts and a hat with a visor.
6. What if there is a baby brother?
If the baby is breastfed by a mother who has had chickenpox, the baby is immunized for the first few months of life. This coverage disappears after 5/6 months. The advice is to use a few precautions: if chickenpox is around in the nursery school, do not keep it too close to the baby. In case of contagion, there is no need to be alarmed, but to consult the pediatrician and decide if it is appropriate to administer an antiviral based on acyclovir.
7. Are there any recommended foods?
There is no particular diet to follow. However, it must be taken into account that chickenpox could cause loss of appetite. So the little one should not be forced to eat. Acidic foods (such as tomatoes, oranges ...) which could irritate any blisters in the mouth are to be avoided. To prefer fresh foods such as yogurt, mozzarella ... But the really important thing is to make the child drink a lot: lots of water, but also fresh juices to entice him to drink.
8. Does the vaccine immunize for life?
Yes, the vaccine gives coverage exactly like chickenpox which once done cannot be repeated.
