Pre-eclampsia hits 3-5 percent of all pregnant women. Its symptoms are raised blood pressure and protein in the urine during the second half of the pregnancy. In rare but very serious cases the condition can be worsened through seizures. Pre-eclampsia can only be treated by treating the symptoms.
You cannot give shingles to someone else, and you cannot catch shingles from someone with shingles. However, if you have an attack of shingles, you can give someone chickenpox if that person makes direct contact with the sores and has never been exposed to chickenpox. Keeping the sores covered under clothing or by plasters will help prevent the spreading of the virus - and chickenpox - to others.
Shingles itself is not contagious, but the varicella zoster virus can be spread from a person with shingles and cause chicken pox in a person who has never had chicken pox or been vaccinated. This would only be possible through direct contact with fluid from the blisters of the shingles rash.
