Neonatal tetanus : ウィキペディア英語版 | Neonatal tetanus
Neonatal tetanus is a form of generalised tetanus that occurs in newborns. Infants who have not acquired passive immunity from the mother having been immunised are at risk. It usually occurs through infection of the unhealed umbilical stump, particularly when the stump is cut with a non-sterile instrument. Neonatal tetanus mostly occurs in developing countries, particularly those with the least developed health infrastructure. It is rare in developed countries. == Signs and symptoms == In neonatal tetanus, symptoms usually appear from 4 to 14 days after birth, averaging about 7 days. The fatality rate for infants has been estimated as 70% to 100%; death usually occurs by the age of 2 weeks.〔 On the basis of clinical findings, four different forms of tetanus have been described. The time from exposure to symptoms may be up to several months.
