It is extremely undesirable now to pick up the infection. But sometimes it is difficult to warn, especially if your oldest child is attending a kindergarten, where something is always found. For example, chickenpox.
No one will ever tell you what chances of getting chickenpox during pregnancy are. Although some predictions can still be made. Since in 90% of cases chicken pox affects the child's body, your risks increase with constant contact with children, and the more, the wider this circle.
As for the average statistical data, pregnant women are infected with chickenpox in 1-1, 5 cases per two thousand women. Regardless of whether they were sick before chickenpox or not, in 90% of cases, expectant mothers have antibodies to this infection. Nevertheless, it is a mistake to think, that you will not get chickenpox again. Now this virus mutated and lifelong immunity to it, as previously thought, does not work. Increasingly, there are cases of repeated infection with chickenpox in adults. So take care and be safe will not be superfluous.
Features of chickenpox during pregnancy
This infection occurs in pregnant women exactly like any other person. Pregnancy does not make the form of chickenpox heavier, is not an aggravating factor and does not increase the risk of complications. However, the varicella-zoster virus, which is the causative agent of chicken pox, poses a real threat to the fetus. However, it is not always the same as the pregnant women themselves think. It all depends on the period at which a woman has become infected, and on the form of leaks.
The most dangerous are the first weeks of pregnancy and, in particular, the last before childbirth. About early terms, then the risk is obvious: the baby's organs are laid, so any diseases and medications can very adversely affect this process. Concerning the virus varicella-zoster, it can leave scarring on the skin of the child, damage the cerebral cortex, cause microphthalmia, hypoplasia of the extremities, cataract, cause convulsive syndrome or delay development and growth of the baby. However, the probability of ugliness and development of pathologies in the mother's transfer of chickenpox at an early date is very low: an average of only 1%. Fatalities and miscarriages occur much more often. If a woman falls ill with chickenpox at a period of up to 14 weeks, the risk for the fetus is estimated at 0, 4%, for a period of up to 20 weeks - no more than 2% after that it practically reduces to zero. However, in the last days before birth, he again rapidly increases, reaching the most critical level within two days before and five days after delivery.
Regarding how the disease proceeds. The development of complications in a pregnant woman and the attachment of a secondary infection increase the risks to the fetus. However, as we have already said, pregnancy itself is not an aggravating factor and chickenpox in pregnant women runs as usual.
What to do if you get sick with chickenpox
Well, of course, even if it's not worn out, do not panic. Your risks are nothing special, you are just as pregnant as everyone. Infection with chickenpox in no way is an indication for abortion, and it says a lot about what. Simply now it will be necessary to pass several more tests and undergo additional examinations, which your doctor will tell you in detail. Among them can be a blood test for PAPP, HGH-markers of prenatal pathology, chorionic biopsy, chordocenesis or amniocentesis.
In order to reduce the risk and minimize the risk for the fetus, a specific immunoglobulin is administered to the pregnant woman. For treatment, usually prescribed acyclovir, to relieve the itching - kalaminovye lotions.
If a woman falls sick with chickenpox 2 days before delivery or within 5 days after delivery, the doctors will be more active. A child can be born with congenital chickenpox, which, usually, is quite hard, causes complications and affects the baby's internal organs. That is why in the case of infection of a woman before the birth, doctors make every effort to delay delivery for at least a few days. Otherwise, after the introduction of the newborn immunoglobulin, he is given a course of antiviral therapy in the infectious department. The same tactic in case of occurrence of chicken pox in a woman during the first five days after birth.
The virus passes through the placental barrier, so now your baby will also have antibodies.
How to protect yourself from chickenpox during pregnancy
Ideally, prevention should begin at the planning stage of pregnancy, and specifically - to be screened for the presence of antibodies to this infection. Already in the period of gestation, a woman is not vaccinated against any viruses.
Try to avoid being in large children's groups. In general, children are carriers of many infections, so pregnancy is not the best time for classes with other children. If you have had contact with an infected patient, you need to establish whether you have antibodies to the virus and, in their absence, inject an immunoglobulin specifically to prevent infection. The injection is done intramuscularly no later than 96 hours after contact. For 10 kg of body weight, 125 units are injected.
