Lymphocytic choriomeningitis (LCM) is a rodent-borne viral infectious disease that presents as aseptic meningitis, encephalitis or meningoencephalitis. Its causative agent is lymphocytic choriomeningitis mammarenavirus (LCMV), a member of the family Arenaviridae. The name was coined by Charles Armstrong in 1934.Lymphocytic choriomeningitis (LCM) is "a viral infection of the membranes surrounding the brain and spinal cord and of the cerebrospinal fluid". The name is based on the tendency of an individual to have abnormally high levels of lymphocytes during infection. Choriomeningitis is "cerebral meningitis in which there is marked cellular infiltration of the meninges, often with a lymphocytic infiltration of the choroid plexuses". Signs and symptoms
LCMV infection manifests itself in a wide range of clinical symptoms, and may even be asymptomatic for immunocompetent individuals. Onset typically occurs between one or two weeks after exposure to the virus and is followed by a biphasic febrile illness. During the initial or prodromal phase, which may last up to a week, common symptoms include fever, lack of appetite, headache, muscle aches, malaise, nausea, and/or vomiting. Less frequent symptoms include a sore throat and cough, as well as joint, chest, and parotid pain. The onset of the second phase occurs several days after recovery, and consists of symptoms of meningitis or encephalitis. Pathological findings during the first stage consist of leukopenia and thrombocytopenia.
It is advised that the newborn be placed skin-to-skin with the mother following vaginal birth, or as soon as the mother is alert and responsive after a Caesarean section, postponing any routine procedures for at least one to two hours. The babys father or other support person may also choose to hold the baby SSC until the mother recovers from the anesthetic.The WHO suggests that any initial observations of the infant can be done while the infant remains close to the mother, saying that even a brief separation before the baby has had its first feed can disturb the bonding process. They further advise frequent skin-to-skin contact as much as possible during the first days after delivery, especially if it was interrupted for some reason after the delivery.La Leche League advises a women to have a delivery team which includes a support person who will advocate to assure that:

The mother and her baby are not separated unnecessarily
The baby will receive only her milk
The baby will receive no supplementation without a medical reason
All testing, bathing or other procedures are done in the parents roomIt has long been known that a mothers level of the hormone oxytocin, sometimes called  "the love hormone", elevates in a mother when she interacts with her infant. In 2019, a large review of the effects of oxytocin found that the oxytocin level in fathers  that engage in SSC is increased as well.
