Puning Babies at Risk

But in some African countries figures between four and 20 per cent have been documented. What can be done about it? The most efficient strategy is, of course, to prevent mothers from contracting syphilis, through general control mea sures for sexually transmitted diseases, which are discussed elsewhere. But there is a specific way of preventing congenital syphilis. All mothers should have a blood test done (it is called a serological test for syphilis) , as early in the pregnancy as possible. Ideally the test should be repeated near the end of pregnancy. If this test proves positive, it indicates that the mother has syphilis and she must be treated. Treatment is highly efficacious and consists of one to three intramuscular injections of a high dose of a long acting penicillin. AIDS is a very recent and alarming development. Several million people worldwide have already been infected with the human immunodeficiency virus (HIV), the causative agent of the acquired immunodeficiency syndrome (AIDS). The highest infection rates are found in North America, Europe and Africa. Risk factors associated with over 80 per cent of AIDS cases in the industrialised world are male homo sexuality and intravenous drug abuse. The epidemiology of the infection is different in Central Africa, where transmission of the virus is mainly through heterosexual contact. This has resulted in a large proportion of women of child-bearing age already Marc Chagall portrayed the protected life in be advised and encouraged to have being infected with HIV in those the womb of a mother-to-be.
