1Congenital infections that can cause birth defects STORCHCongenital infections that can cause birth defects
2SyphilisIs an infectious disease. The bacteria that causes it spreads through broken skin or mucous membranes. It is most often spread by sexual contact.Pregnant mothers infected with the disease can pass it to the baby developing in their womb. This is called congenital syphilis.Syphilis is widespread in the United States. It mainly involves sexually active adults between ages 20 to 29.
5SymptomsThe symptoms of syphilis depend on the stage of the disease. Many people do not have symptoms.In general, painless sores and swollen lymph nodes are symptoms of primary syphilis. Those with secondary syphilis may also have fever, fatigue, aches and pains, and loss of appetite, among other symptoms. Tertiary syphilis causes heart, brain, and nervous system problems.
6Dangers to Fetus Infant skin lesions Lymph node enlargement Multiple organ problemsMost characteristic = skeletal abnormalitiesVision/hearing problems25% of infants die in first few months
7Toxoplasmosis Is an infection due to the parasite Toxoplasma gondii . Is found in humans worldwide, and in many species of animals and birds. Cats are the definitive host of the parasite.Human infection may result from:Blood transfusions or solid organ transplantsCarelessly handling cat litterEating contaminated soilEating raw or undercooked meat (lamb, pork, and beef)
9ToxoplasmosisHealthy individuals do not usually display symptoms. When symptoms do occur, they are usually mild, resembling infectious mononucleosis , and include the following: enlarged lymph nodes muscle pains fever that comes and goes general sick feeling tired
10Prevent your cats from getting toxo Feed them dry or canned cat food and keep them indoors.Cats can become infected by eating or being fed raw or undercooked meat that is infected with the parasite, or by eating infected prey such as birds or rodents.Any cat that is allowed access to outdoors should be kept off beds, pillows, or other furniture that you also use.
11Damage to FetusA pregnant host has a 40-60% chance of transmitting the infection to baby w/ serious damage1st trimester=fetal death or severe impairment1st or 2nd = eye abnormalities, hydrocephalus, seizures3rd = often no impairments
12OtherViruses including varicella zoster which causes chicken pox and shingles; polioMiscarriageVisual impairmentsCerebral palsyDeaf-blindness
16Rubella Symptoms could include: Rash Runny Nose Red Rash Swollen Lymph NodesFeverPainHeadacheJoint PainMalaiseBruisesMuscle PainEye RednessBody AcheBruises EasilyFeels Hot to TouchPerianal Rash
17RubellaMost common viral cause of birth defects until 1969 when vaccination program began80% risk of transmission to fetus during 1st trimester; majority sustaining damageAfter 16th week risk of severe impairment declines; fetus may acquire the infection without sustaining disabilityImpairments range from none to several and include; visual impairments, hearing defects, deaf-blindness, abnormalities of lungs and kidney, seizures, CPSome impairments may have later onset and include; encephalitis and lack of motor coordinationNo effective antiviral treatment for rubella
18Signs and tests A nasal or throat swab may be sent for culture. A blood test can be done to see if a person is protected against rubella. All women who may become pregnant should have this test. If the test is negative, they will receive the vaccine.
22CytomegalovirusCMV is an extremely common organism worldwide. It is believed that about 85 percent of the adults in the United States have been infected by CMV at some point in their lives. CMV is found in almost all of the body's organs. It is also found in body fluids, including semen, saliva, urine, feces, breast milk, blood, and secretions of the cervix (the narrow, lower section of the uterus).CMV is also able to cross the placenta (the organ that provides oxygen and nutrients to the unborn baby in the uterus). Because CMV can cross the placental barrier, initial infection in a pregnant woman can lead to infection of the developing baby.
23CMV SymptomsTransmission to a fetus by a pregnant woman can result in severe damage; 40% risk of transmissionRange from no symptoms to severe or fatalInclude organ damage, microcephaly, visual impairmentsAsymptomatic children may develop problems later such as hearing loss
24PreventionCurrently, there is no vaccine to prevent CMV infection. For those who have close contact with children, especially pregnant women or women who might become pregnant, hand washing is effective at reducing the risk of infection, as are not sharing eating utensils with young kids and avoiding intimate contact with anyone who has a CMV infection.
25CMV Testing of InfantsTests that detect the virus are used to diagnosis CMV infection at birth (congenital CMV infection). A diagnosis of congenital CMV infection can be made if the virus is found in an infant’s urine, saliva, blood, or other body tissues within 2-3 weeks after birth. Antibody tests cannot be used to diagnose congenital CMV; a diagnosis can only be made if the virus is detected within 2-3 weeks of life.
27HerpesHerpes simplex virus type 1 (HSV-1) is usually associated with infections of the lips, mouth, and face. It is the most common herpes simplex virus and most people develop it in childhood. HSV-1 often causes lesions inside the mouth, such as cold sores (fever blisters), or infection of the eye (especially the conjunctiva and cornea). It can also lead to infection of the lining of the brain (meningoencephalitis). It is transmitted by contact with infected saliva. By adulthood, up to 90% of people will have antibodies to HSV-1.
32HSV - 2Herpes simplex virus 2 (HSV-2) is sexually transmitted. Symptoms include genital ulcers or sores. In addition to oral and genital sores, the virus can also lead to complications such as infection of the lining of the brain and the brain itself (meningoencephalitis) in neonatal infants due to infection during birth. However, some people have HSV-2 but do not show symptoms. Up to 30% of U.S. adults have antibodies against HSV-2. Cross-infection of type 1 and 2 viruses may occur from oral-genital contact.
33Dangers to FetusRange from severe impairments such as brain inflammation, multiple organ damage, mental retardationto milder forms of impairment such as blistersTransmission can be prevented by C-section within 4 hours of the rupture of the amniotic membrane
