2. 2. The first group of 14 children, who acquired HCV infection early in life, presumably from their mothers, demonstrated biochemical evidence of liver disease in the first 12 months of life. Human T-lymphocyte retroviruses. Carrol L., Osman M., Davies D.P. Perinatal maternal infection can lead to severe disease in the newborn, but no evidence suggests transmission through breast milk.28., 224. Postexposure prophylaxis is given to thousands of patients each year. Ureta-Vidal A., Angelin-Duclos C., Tortevoye P. Mother-to-child transmission of human T-cell leukemia/ lymphoma virus type I: Implication of high antiviral antibody titer and high proviral load in carrier mothers. Assessment of the risk of ebola virus transmission from bodily fluids and fomites. Patel M., Shane A.L., Parashar U.D. No evidence indicates transmission of syphilis via breast milk in the absence of a breast or nipple lesion. Breastfeeding and the expression of or pumping of breast milk (referred to as expressed breast milk) for later use are not sterile activities. Ando et al11 showed that freezing and thawing breast milk decreased the infectivity of HTLV-I. Lin H.H., Kao J.H., Chen P.J. For these reasons the transmission of HTLV-I/II via accidental expressed breast milk exposure is thought to be extremely low. Furnia A., Lal R., Maloney E. Estimating the time of HTLV-I infection following mother-to-child transmission in a breast-feeding population in Jamaica. The organism does not seem to cause significant disease in a healthy infant. Expressed colostrum or breast milk also can be given if the infant is able to feed orally. In general, women who are known to be HIV seronegative should be encouraged to breastfeed. Community-acquired MRSA is so common, it is now being observed in hospital outbreaks.24., 144., 164., 358. Pillay K., Coutsoudis A., York D. Cell-free virus in breast milk of HIV-1seropositive women. Sawada et al363 demonstrated in a rabbit model that HTLV-I immunoglobulin protected against HTLV-I transmission via milk. Spontaneous resolution does occur, but therapy for persistent lesions or growths in anatomically problematic locations is appropriate. It most often occurs in the late winter and spring. Doxycycline use in a nursing mother is not routinely recommended. This may be a result of the long incubation period (generally 4 to 6 weeks, but can be up to 1 year, with reports of incubation periods of several years), a lack of symptoms early in an infectious animal, or airborne transmission from bats in enclosed environments (caves, laboratories, houses). An infant should be separated temporarily from the suspected source if symptoms suggest active disease or a recent TST documents conversion, and separation should continue until the results of the chest radiograph are seen. Silver384 reviewed 11 published reports and concluded that Lyme disease during pregnancy is uncommon, even in endemic areas. The prevalence of positive serologic test titers increases with age, indicating past exposure and infection. No evidence indicates that RSV causes intrauterine infection, adversely affects the fetus, or causes abortion or prematurity. Providing the infant with expressed breast milk is acceptable. In one study of 235 susceptible pregnant women, the annual seroconversion rate was 1.4%.223. Invasive disease can occur through local spread, and may occur more often in the genitourinary tract (urethra, bladder, ureters, kidneys), but usually develops in association with candidemia. Various regimens have been proposed to eradicate MRSA colonization, but none have been proven to be highly efficacious. Updated U.S. public health service guidelines for the management of occupational exposures to HIV and recommendations for post exposure prophylaxis. No information is available on the role of milk antibodies in protection against infection in infants.389 It is not believed that Chlamydia is transmitted via breast milk. Maternal-neonatal transmission was documented when the mother developed hepatitis E infection in the third trimester. For recurrence of persistence of the thrush, more respondents reported treating the mother or both the infant and mother with fluconazole, and almost a quarter reported using other therapies. The yeast connection: is Candida linked to breastfeeding associated pain? Alternatively, observe in isolation for 18 days for modified measles. Perinatal infection has been noted in several case reports of infants infected in utero several days before birth who had severe disease manifesting with neurologic manifestations (paralysis) but without fever, irritability, or vomiting. One acute breast milk sample on day 7 after the onset of illness and a convalescent breast milk sample on day 15 from the same woman were positive for Ebola virus by both culture and PCR testing.30 In the same study, saliva remained virus positive for a mean of 16 days after disease onset, urine was positive for a mean of 28 days, and semen for a mean of 43 days after the onset of disease. Ekpini E.R., Wiktor S.Z., Satten G.A. Song Y.M., Sung J., Yang S. Factors associated with immunoprophylaxis failure against vertical transmission of hepatitis B virus. Estimates suggest that in children younger than 5 years old rotavirus infection leads to more than 100 million occurrences of diarrhea, 2 million hospital admissions, and 500,000 deaths each year.157 Fecal-oral transmission is the most common route, but fomites and respiratory spread may also occur. Gerber S.I., Jones R.C., Scott M.V. The breast milk was not tested.140, In a review from 1931 to 1981, Sepkowitz375 reported on 27 cases of secondary vaccinia in households. Case reports and reviews. Treatment of the mother with ceftriaxone, cefixime, penicillin, or erythromycin is without significant risk to the infant. No evidence indicates that malaria is transmitted through breast milk. The complete avoidance of breastfeeding is a crucial component for the prevention of perinatal HIV infection in the United States and many other countries. The infection occurs as either an acute coinfection of HBV and HDV or a superinfection of HBV carriers. Layde P.M., Webster L.A., Braughman A.L. Infant: Isolate from other infants but not from mother. Mefloquine is not approved for infants or pregnant women. For these reasons, the risk for transmission of HIV via expressed breast milk consumed by another child is thought to be extremely low. The infrequent occurrence of significant illness with HHV-7 infection, with the absence of sequelae except in patients who had transplantation surgery at older ages and the common occurrence of infection in childhood argue, that no reason to proscribe against breastfeeding for HHV-7 positive women exists. The virus is detected by its capacity to transform B lymphocytes into persistent lymphoblastoid cell lines. The cases of vertical transmission occurred with near-term infection in the mothers, and the infants developed illness within 3 to 7 days of delivery.146., 339. Culturing of EBV from various fluids or sites is difficult. Ishak R., Harrington W.J., Azeuedo V.N. Maternal susceptibility to poliovirus should be determined before conception and poliovirus vaccine offered to susceptible women. Contact precautions include cohorting or a private room, gloves and gowns at all times, and handwashing after removal of gown and gloves. They thought that breastfeeding may help protect the suckled breast against cancer.194, Others274 have suggested that Tanka women are ethnically a separate people and that left-sided breast cancer may be related to their genetic pool and not to their breastfeeding habits. The mortality risk was 1.9% at 1 year and 4.8% at 2 years of follow-up. The COVID-19 resource centre is hosted on Elsevier Connect, the company's public news and information website. Life with an autoimmune disorder varies with the disorder. Hepatitis B Hepatitis B is a liver infection caused by the hepatitis B virus (HBV), which is transmitted by blood, semen or other body fluid from an infected person. The four species of malaria, Plasmodium vivax, P. ovale, P. malariae, and P. falciparum, vary in the specific aspects of the disease they produce. Methicillin-resistant Staphylococcus aureus in milk. Bates T. Poliomyelitis in pregnancy, fetus and newborn. In: Remington J.S., Klein J.O., editors. If lesions are on the breasts or nipples, breastfeeding or using expressed milk is contraindicated until treatment is complete and the lesions have cleared. Despite efforts to identify either a soluble substance or specific cell fractions (gamma/delta T cells) in colostrum and breast milk that affect infants immune responsiveness, no unified theory explains the various reported changes and no evidence has identified a consistent, clinically significant effect.39., 213., 319., 367. Although uncommon in the United States, leprosy occurs throughout the world. Another study from Arkansas focused on contamination of feeding tubes during administration of expressed breast milk or formula.277 Ten infants in the neonatal intensive care unit (NICU) were exposed to greater than 105 gram-negative bacteria in their feeding tubes. Growth faltering due to breastfeeding cessation in uninfected children born to HIV-infected mothers in Zambia. Davis M.K. The overall prevalence of HTLV-I infection during childhood is unknown because the majority of individuals do not manifest illness until much later in life. 1. Yamanouchi K., Kinochita K., Moriuchi R. Oral transmission of human T-cell leukemia virus type 1 into a common marmoset as an experimental model for milk-borne transmission. TB infection: Abnormal CXR suggestive of active disease, a. Abnormal CXR not suggestive of active disease, b. Abnormal CXR suggestive of active disease, Immunoglobulin M (IgM) antibody against HAV, IgM antibody against hepatitis B core antigen, Limited evidence of transmission via breastfeeding or of serious disease in infants, HAV in pregnancy associated with premature birth, Increased risk for vertical transmission with HBeAg+, in countries where HBV is endemic, or early in maternal infection, before Ab production, Virtually no risk after HBIG and HBV vaccine, Increased risk when mother HIV+ and HCV+ or with increased HCV RNA titers, Delavirdine (RNA negative strand, circular), Requires coinfection/superinfection with HBV, None (except to prevent HBV infection, give HBIG/HBV vaccine), Prevent HBV infection with HBIG and vaccine, Severe disease in pregnant women (20% mortality), Usually subclinical infection in children, Related to calicivirus and flavivirus (RNA), TT virus (DNA, circular, single stranded). Recurrent neonatal group B streptococcal disease associated with infected breast milk. Diagnostic approach to patient with chronic viral hepatitis. Arnon S.S., Damus K., Thompson B. The infant should be placed on contact precautions, in addition to the routine standard precautions. Morel A.S., Wu F.W., Della-Latta P. Nosocomial transmission of methicillin-resistant Staphylococus aureus from a mother to her preterm quadruplet infants. The risk for transmission from mother to infant occurs mainly during delivery in the passage through the infected birth canal and occasionally from postpartum contact with the mother (or her partner). If you have Hepatitis B infection, there is no need to delay starting breastfeeding until your infant is immunized against hepatitis B. Honey may contain botulism spores, which can germinate in the infant gut. Expand All How do STIs affect pregnant women? The clinical disease associated with HIV-2 has similar symptoms to HIV-1 infection but progresses at a slower rate to severe immunosuppression. It may resemble neonatal sepsis, with fever, anemia, and splenomegaly occurring in the most neonates and hyperbilirubinemia and hepatomegaly in less than half. In a collective review of the etiologic factors in cancer of the breast in humans, Papaioannou325 concludes, Genetic factors, viruses, hormones, psychogenic stress, diet, and other possible factors, probably in that order of importance, contribute to some extent to the development of cancer of the breast.325. Before No specific group of congenital malformations have been described in association with in utero measles infection, although teratogenic effects of measles infection in pregnant women may rarely manifest in the infants. Lee H.C., Enright A., Benitz W.E. Anti-TB medications (isoniazid, rifampin, pyrazinamide, aminoglycosides, ethambutol, ethionamide, p-aminosalicylic acid) have been safely used in infancy, and therefore the presence of these medications in smaller amounts in breast milk is not a contraindication to breastfeeding. 1. The infant can and should continue to receive breast milk for the potential specific and nonspecific antiviral immunologic benefits. Wong-Staal F., Gallo R.C. Children younger than 3 months of age seem to be protected because of passively acquired antibodies from the mothers, and some additional benefits may be received from breast milk. The dilemma is the use of replacement feeding versus breastfeeding in countries where breastfeeding provides infants with significant protection from illness and death due to malnutrition or other infections. The availability and free access to antiretroviral medications must also improve. When a mother has no suspicious breast lesions, breastfeeding is acceptable as long as appropriate therapy for suspected or proven syphilis is begun in the mother and infant. Zhang R.J., Zeng J.S., Zhang H.Z. Approximately 15% of infants born after primary infection in a pregnant woman will manifest at least one sequela of prenatal infection.96. Only one of 18 (5%) infants became positive for CMV at 62 days of life, and this infant was clinically asymptomatic. Mumps virus has been isolated from saliva, respiratory secretions, blood, testicular tissue, urine, CSF in cases of meningeal involvement, and breast milk. Breastfeeding family history and breast disease. Gardner S.E., Mason E.O., Jr., Yow M.D. hepatitis B (HBV) and hepatitis C; BBVs causing hepatitis, a disease affecting the liver. In general the acid stools (pH 5.1 to 5.4) of human milk fed infants encourage Bifidobacterium species. Eradication of GBS mucosal colonization in the infant or the mother may be difficult. The first issue is determining the etiology of the hepatitis, which then allows for an informed discussion of risk to the fetus/infant. The three infants who were fed expressed breast milk with contamination at greater than 105 organisms remained well, but the seven formula-fed infants with high levels of bacterial contamination in the feeding tubes developed necrotizing enterocolitis. No reports of transmission to an infant through breastfeeding are available. Yoshida M., Yamagami N., Tezuka T. Case report: Detection of varicella-zoster virus DNA in maternal breast milk. Sax H., Posfay-Barbe K., Harbarth S. Control of a cluster of a community-associated methicillin-resistant. In severe infections the clinical course can include dehydration, electrolyte abnormalities, and acidosis and can contribute to malnutrition in developing countries. Probable transmission of brucellosis from breast milk to a newborn. In mothers with unknown HIV status or known HIV infection, the rates of vertical transmission were 4% to 100%, whereas the rates varied between 0% and 42% in known HIV-negative mothers.113 These same studies suggest that maternal coinfection with HIV, HCV genotype, active maternal liver disease, and the serum titer of maternal HCV RNA may be associated with increased rates of vertical transmission.263., 307., 461. Hinckley A.F., OLeary D.R., Hayes E.B. Anthony et al15 noted that many infants are colonized with GBS, but the actual attack rate for GBS disease is low and difficult to predict. Beasley R.P. Breast milk and the risk of cytomegalovirus infection. Centers for Disease Control and Prevention: Hepatitis C FAQs for health professionals. Schrag S., Gorwitz R., Fultz-Butts K. Prevention of perinatal group B streptococcal disease. Coovadia H.M., Rollins N.C., Bland R.M. Schwer M., Moosa A. Congenital and postnatally acquired cytomegalovirus infections: Long-term follow-up. Avoiding breastfeeding led to an 80% decrease in transmission. Any predisposing risk factors for candidal infection in mothers and infants should be reduced or eliminated to improve the chance of rapid, successful treatment and to decrease the likelihood of chronic or recurrent disease. Personal contact and breastfeeding between mother and infant can continue until the onset of fever, when immediate isolation (at home) should begin. Congenital lymphocytic choriomeningitis virus infection in twins. Documentation of RSV infection is rarely made in adults, and spread from a mother or other household contacts probably occurs before a diagnosis can be made. Despite reportedly observing appropriate precautions, the individuals wife developed vesicles on both areolae (secondary contact vaccinia). The impact of breastfeeding on the health of HIV positive mothers and their children in sub-Saharan Africa. Transmammary transmission of Strongyloides species has been described in dogs, ewes, and rats.211., 302., 382. Dunkle L.M., Schmidt R.R., OConnor D.M. The incidence of breast cancer is low among groups who had nursed their infants, including lower economic groups, foreign-born groups, and those in sparsely populated areas.262 The frequency of breast cancer in mothers and sisters of a woman with breast cancer is two to three times that expected by chance. . No infant was given CMV-seropositive donor milk or blood. The foregoing data suggest that transmission is more likely to be vertical, before, or at delivery rather than via breastfeeding. Roggiani M., Schlievert P.M. Streptococcal toxic shock syndrome, including necrotizing fasciitis and myositis. MRSA and methicillin-susceptible S. aureus were identified respectively in eight samples (0.8%) from three mothers and 281 samples (19.3%) from 73 mothers of the tested expressed breast milk before pasteurization. The age of infants seems to relate to their susceptibility to illness. Fewer than five cases are reported annually in the United States. Strongyloides stercoralis is a nematode (roundworm). The disease has been reported from 41 of the 50 states in the United States and from eight countries on four continents. Perinatal mumps (transplacentally or postnatally acquired) has rarely if ever been documented. S. aureus requires only a small inoculum (10 to 250 organisms) to produce colonization in newborns, most often of the nasal mucosa and umbilicus.193 By the fifth day of life, 40% to 90% of the infants in the nursery will be colonized with S. aureus. Garner J.S. Ribavirin has been described as teratogenic in various animal species and is contraindicated in pregnant women. Kawanabe M., Nojima H., Uchikawa R. Transmammary transmission of Strongyloides ratti. Person-to-person spread of Lassa fever is believed to be common, and transmission within households does occur.212 This may relate to prolonged viremia and excretion of the virus in the urine of humans for up to 30 days.330 The possibility of persistent virus in human urine, semen, and blood after infection exists for each of the arenaviruses. Generally, every child will have at least one episode of rotavirus infection by 5 years of age.157 In developed countries, rotavirus is often associated with diarrhea requiring hospitalization in children younger than 2 years of age, but rarely associated with death. Management of Newborn Whose Mother (or Other Household Contact) Has Tuberculosis (TB). More than 90% of children younger than 13 years old infected with HIV-1 have been infected by mother-to-child transmission. Postnatal infection with toxoplasmosis is usually asymptomatic. Type III is the most common serotype causing disease. Horn P. Poliomyelitis in pregnancy: A twenty-year report from Los Angeles County, California. Isolation or identification of the infectious agent from the colostrum, breast milk, or an infectious lesion of the breast is important but not necessarily proof of transmission to an infant. In the weaning intervention group, 69% of mothers stopped breastfeeding by 5 months compared with a median duration of breastfeeding of 16 months in the control group. Gotuzzo E. HTLV-I: A new problem for latin America. Bortolotti et al47 described two groups of children with HCV infection whom they observed for 12 to 48 months. Refraining from breastfeeding is a crucial aspect of preventing perinatal HIV infection in the United States and many other countries. Germs in the vagina can also be transmitted to the baby during birth. Serologic evidence for congenital transmission of human herpesvirus 6. The protective effect of breast milk has been identified in the milk of noninfected donors.151 The antiparasitic effect does not result from specific antibodies but rather from lipase enzymatic activity. The other issue for breastfeeding infants is the question of maternal vaccination with smallpox in a preexposure event vaccination program. This transmission rate is considerably lower than others reported in the literature. The fear and anxiety that arise with the occurrence of any infectious disease are even greater in the situation of the breastfeeding mother-infant dyad. Immunocompetent individuals show no evidence of invasive infection, and no evidence exists that documents fetal infection from maternal infection during pregnancy. Ribavirin is not recommended for routine use. Abstract Breast milk transmission of maternal viral infection is well established for CMV and HIV-1. HTLV-I Transmission Related to Duration of Breastfeeding. The lack of illness is thought to result from transplacental passive transfer of protective antibodies from the mother. Ghent International Working Group on Mother-to-Child Transmission of HIV. Thior I., Lockman S., Semeaton L.M. Standard precautions include preventing contact with blood, all body fluids, secretions and excretions, nonintact skin, and mucous membranes by (1) careful handwashing before and after every patient contact; (2) use of gloves when touching body fluids, nonintact skin, or mucous membranes or any items contaminated with body fluids (linens, equipment, devices, etc. Breastfeeding by a mother with symptomatic giardiasis is acceptable when consideration is given to the presence of the therapeutic agents in the breast milk. Examination of colostral milk did not demonstrate any hookworm larvae.303. Mechanism of vertical transmission of hepatitis G. Lin H.H., Kao J.H., Hsu H.Y. Additionally, precautions based on the predominant modes of transmission have been recommended to protect against infection through the airborne route, direct contact, or contact with droplets. The usual period of viral shedding and presumed contagiousness lasts 1 to 3 weeks. Of the cases of sudden infant death from botulism, no infants were breastfed within 10 weeks of death. Probable breast milk borne brucellosis in a young infant. Breastfeeding should continue with appropriate support and problem-solving with a professional who is knowledgeable about breastfeeding. None of these infants developed signs of liver disease. Lubani M.M., Dudin K.I., Sharda D.C. Neonatal brucellosis. Ohto H., Terazawa S., Sasaki N. Transmission of hepatitis C virus from mothers to infants. However, other routes of transmission exist because HCV infection occurs even in the absence of obvious direct contact with significant amounts of blood. In utero transmission has been suggested by some studies,125 whereas intrapartum or postpartum transmission was proposed by Ohto et al308 when they documented the absence of HCV RNA in the cord blood of neonates who later became HCV RNA positive at 1 to 2 months of age. Transmission via blood products and vertical transmission (mother to infant) are rare.440 Transmission in daycare settings has been clearly described. Breastfed women have the same breast cancer experience as nonbreastfed women, and no increase is seen in benign tumors. There are no reports of Lyme disease being spread to infants through breast milk. When acute peripartum or postpartum hepatitis occurs in a mother and HBV infection is a possibility, with its associated increased risk for transmission to the infant, a discussion with the mother or parents should identify the potential risks and benefits of continuing breastfeeding until the etiology of the hepatitis can be determined. Strongyloides papillosus: prenatal and transmammary infection in ewes. Those antibodies are present in high amounts in colostrum, the first milk that comes out of the breasts after birth. Cherry J.D. No well-controlled clinical trials define the most appropriate or most effective method(s) of treatment for candidal infection in breastfeeding mother-infant pairs. Strongyloides larvae was identified in only one sample of milk from 25 nursing mothers.53. Despite the frequent occurrence of bacteremia, no evidence indicates breast involvement or transmission through breast milk. Stagno S., Cloud G.A. Nulliparity and absence of breastfeeding had been considered important risk factors for breast cancer. Postnatal infection later in infancy occurs via breastfeeding or contact with infected fluids (e.g., saliva, urine) but, again, rarely causes clinical illness in full-term infants. No documented evidence indicates that women with breast cancer have RNA of tumor virus in their milk.
