History
Although it had been recognized from as early as the time of the Hippocratic corpus that women in childbed were prone to fevers, the distinct name, "puerperal fever" appears in historical records only from the early 18th century.The death rate for women giving birth decreased in the 20th century in developed countries. The decline may be partly attributed to improved environmental conditions, better obstetrical care, and the use of antibiotics. Another reason appears to be a lessening of the virulence or invasiveness of Streptococcus pyogenes. This organism is also the cause of scarlet fever, which over the same period had declined but has seen a rise in last decade worldwide especially in Asia with smaller outbreaks in US and Canada. UK had reported 12,906 cases between September 2015 and April 2016 which is the largest outbreak since 1969. "The Doctors Plague"
From the 1600s through the mid-to-late 1800s, the majority of childbed fever cases were caused by the doctors themselves. With no knowledge of germs, doctors did not believe hand washing was needed. Hospitals for childbirth became common in the 17th century in many European cities. These "lying-in" hospitals were established at a time when there was no knowledge of antisepsis or epidemiology, and women were subjected to crowding, frequent vaginal examinations, and the use of contaminated instruments, dressings, and bedding. It was common for a doctor to deliver one baby after another, without washing his hands or changing clothes between patients. The first recorded epidemic of puerperal fever occurred at the Hôtel-Dieu de Paris in 1646.
Unspecified communication disorder – for those who have symptoms of a communication disorder but who do not meet all criteria, and whose symptoms cause distress or impairment. Examples
Examples of disorders that may include or create challenges in language and communication and/or may co-occur with the above disorders:

autism spectrum disorders - autistic disorder, pervasive developmental disorder not otherwise specified (PDDNOS), and Asperger disorder – developmental disorders that affect the brains normal development of social and communication skills. expressive language disorder – affects speaking and understanding where there is no delay in non-verbal intelligence. mixed receptive-expressive language disorder – affects speaking, understanding, reading and writing where there is no delay in non-verbal intelligence. specific language impairment – a language disorder that delays the mastery of language skills in children who have no hearing loss or other developmental delays. SLI is also called developmental language disorder, language delay, or developmental dysphasia. Sensory impairments
Blindness – A link between communication skills and visual impairment with children who are blind is currently being investigated. Deafness/frequent ear infections – Trouble with hearing during language acquisition may lead to spoken language problems. Children with frequent ear infections may temporarily develop problems pronouncing words correctly. Some of the above communication disorders can occur with people who use sign language. The inability to hear is not in itself a communication disorder. Aphasia
Aphasia is loss of the ability to produce or comprehend language. There are acute aphasias which result from stroke or brain injury, and primary progressive aphasias caused by progressive illnesses such as dementia.
