Toxoplasmosis is an infectious disease caused by a parasite called Toxoplasma Gondii. As with other infectious diseases such as varicella or rubella, it can only be passed once in a lifetime.

At the beginning of pregnancy, or even in the preconceptional consultation, the gynecologist requests a general analysis that includes serology to know the status of each patient against toxoplasma as well as other infectious agents that can infect the fetus during pregnancy.

There is no vaccine to administer to women who are not immunized before or during pregnancy, so prevention is the key in those susceptible to being infected.

  • You should avoid contact with materials that may be contaminated with cat feces. If it is not possible, use gloves.
  • Do not eat raw or undercooked meat and eggs.
  • Eat cooked or frozen meat at -18ºc for at least 72 hours.
  • Avoid hamburgers because the central part can remain raw after cooking.
  • Avoid sausages or products made with raw meat if they have not been previously frozen.
  • Use gloves if raw meat is handled, wash hands frequently after handling avoiding contact with mucous membranes (mouth, eyes).
  • Wear gloves if you manipulate earth in gardens, field etc.
  • Wash fruits and vegetables very well. For this you can use amukine for sale at any pharmacy.

In the event that these measures have not been carried out, a maternal infection may occur. In this situation is indicated an antibiotic treatment that will be different if it is confirmed after the study of amniotic fluid from week 20-21 that the fetus is also infected, which does not always happen.

After birth, proper follow-up by a specialized pediatrician is important, who will refer the patient to other specialists to perform additional studies and treat possible injuries that may appear months later.
