Breastfeeding issues for selected maternal infections

Organisma Predominant modes of transmissionb Usual timing of infectionc Evidence for transmission in breast milk Clinical significanced
Bacillus anthracis (anthrax) Contact—animals, animal products, cutaneous lesions; airborne NA None BF/BM; cover lesions; medications for therapy and prophylaxisf
Borrelia burgdorferi (Lyme disease) Arthropod NA DNA by PCR; no reports of illness in infants BF/BM
Candida spp Contact Postnatal (colonization, susceptible infants) Contact with breast, not breast milk BF/BM
Dengue viruses (1–4) Mosquito NA None BF/BM
SARS-associated coronavirus Contact; droplet NA None BF/BM
Toxoplasmosis gondii Animal-borne; soil, fecal-oral Congenital None BF/BM
Treponema pallidum (syphilis) Body fluids; blood Congenital, perinatal None Delay BF/BM 24-hr after initiating maternal therapy; empiric treatment of infant
Vaccinia virus (smallpox vaccine) Contact; possibly airborne NA One case report, contact with breast lesion BF/BMe
Variola virus (smallpox) Contact; airborne NA None Avoid BF/BM; separation PI
West Nile virus Mosquito; blood NA One case report (no illness in infant) BF/BM

This is a selected, limited list intended to consider some important organisms that cause infection in the neonate or infant and possible issues related to breastfeeding and breast milk.

Abbreviations: BF, breastfeeding; BM, expressed breast milk; NA, not applicable; PCR, polymerase chain reaction; PI, period of infection; SARS, severe acute respiratory syndrome.

a

Organisms that cause various clinical illnesses in the infant and the mother; specific illnesses are too numerous to list.

b

For breastfeeding and non-breastfeeding situations; does not include all possible or reported modes of transmission (airborne, body fluids, contact, droplet, food-borne).

c

Does not include all possible times of transmission. If “NA,” the timing of infection is not associated frequently with pregnancy, delivery, or neonates and infants.

d

Notes the appropriateness of breastfeeding or use of breast milk when the mother has an infection with that specific organism.
