What symptom does intrauterine infection have?
summary
Intrauterine infection, also known as congenital infection or mother to child transmission disease, refers to the intrauterine infection of the fetus caused by infection during pregnancy. The main route of intrauterine infection is vertical transmission of pathogenic microorganism to fetus through placenta; The retrograde diffusion of pathogenic microorganisms in the lower genital tract of pregnant women; Perinatal infection during delivery. What symptom does intrauterine infection have? Let's talk about it.
What symptom does intrauterine infection have?
3% - 8% of the newborns were infected by maternal bacteria, viruses and protozoa. It is estimated that more than 70-1.6 million newborns will suffer from congenital infection every year. According to the statistics of the Ministry of health, there are about 120 million hepatitis B virus carriers in China, and 40% of pregnant women with hepatitis B virus carriers can transmit the virus to the fetus. In addition, domestic investigation found that the infection rates of cytomegalovirus and Toxoplasma gondii in newborns in China are as high as 1% - 2%. It has been confirmed that intrauterine infection is an important cause of congenital defects and disabilities.
Many pathogenic microorganisms can cause congenital infection of fetus, among which intrauterine infection caused by virus is the most widespread. The more serious harm is hepatitis B virus (because there are about 120 million hepatitis B virus carriers in China) and cytomegalovirus. Toxoplasma gondii is the main parasite causing intrauterine infection. The infection rate of Toxoplasma gondii is about 4% - 9% in China. It is estimated that about 4-9 million people are infected with Toxoplasma gondii in China. Other microorganisms causing intrauterine infection include Treponema pallidum, Neisseria gonorrhoeae and chlamydia. Chlamydia infection has been paid more attention recently.
The influence of intrauterine infection on the fetus is a complex problem, which is related to the gestational age at the time of infection, the immune status of pregnant women, the types of pathogenic microorganisms and the severity of infection. It is generally believed that the infection in early pregnancy is more serious, because this period is the sensitive stage of fetal organ development. Therefore, it is very important for pregnant women to prevent infection in early pregnancy to protect the health of their offspring. In general, intrauterine infection can lead to abortion, congenital malformation (including congenital disability), stillbirth and so on. However, different pathogenic microorganisms have different characteristics of fetal injury: herpesvirus infection mainly damages the fetal central nervous system, causing microcephaly, brain hypoplasia, etc; Congenital cataract is a typical feature of rubella virus infection; Coxsackievirus infection often causes congenital heart disease, such as patent ductus arteriosus, ventricular septal defect, etc; One consequence of congenital cytomegalovirus infection is neonatal hepatitis syndrome.
matters needing attention
Amniotic fluid infection is intrauterine infection of bacteria, will affect the baby, so should pay close attention to treatment, or give up, if the baby is soon born, you can let him out early, hypoxia is also bad for the baby! After a long time, the baby is not safe! Fetal hypoxia in the uterus, will make the anal sphincter relaxation, meconium excretion pollution amniotic fluid. Once the sample water pollution is found, it indicates fetal intrauterine hypoxia. Generally, acute hypoxia can be shown in fetal heart rate and fetal movement, while chronic hypoxia sometimes has no obvious clinical signs.
