Teratogens that Threaten Pregnant Mothers

Smoking and Its Impact on Pregnancy

Smoking during pregnancy poses serious risks to both the mother and the baby. The use of tobacco increases the chances of premature labor, which can result in various health complications for the infant. However, by quitting smoking early in pregnancy, the risk can be reduced to that of a non-smoker. Additionally, tobacco use is associated with low birth weight, issues with the placenta, and the occurrence of sudden infant death syndrome (SIDS). Furthermore, scientific studies have found a link between prenatal smoking and oral clefts, which are defects affecting the mouth and lips of newborns.


Rubella Vaccination: Importance and Risks

The measles-mumps-rubella (MMR) vaccine plays a crucial role in safeguarding the health of children under the age of three. With a success rate between 88 and 97 percent, this vaccine effectively protects against these three diseases. However, recent declines in MMR vaccination rates have resulted in a heightened risk of rubella, a highly contagious illness.

One of the most concerning consequences of contracting rubella during pregnancy is the potential transmission of the virus to the fetus. If a pregnant woman becomes infected with rubella during the first trimester, there is a 90% chance of the virus being passed on to the developing baby. This can lead to severe outcomes, including fetal death or the development of congenital rubella syndrome (CRS).

Children born with CRS face a range of health issues. These may include heart defects, autism, and diabetes, among others. Such complications underscore the critical importance of ensuring high MMR vaccination rates to protect both pregnant women and their unborn children from the devastating effects of rubella.
