Editing Infection (section)

====Course of infection====
Different terms are used to describe how and where infections present over time. In an ''acute'' infection, symptoms develop rapidly; its course can either be rapid or protracted. In ''chronic'' infection, symptoms usually develop gradually over weeks or months and are slow to resolve.<ref>{{Citation|last1=Boldogh|first1=Istvan|title=Persistent Viral Infections|date=1996|url=http://www.ncbi.nlm.nih.gov/books/NBK8538/|work=Medical Microbiology|editor-last=Baron|editor-first=Samuel|edition=4th|publisher=University of Texas Medical Branch at Galveston|isbn=978-0-9631172-1-2|pmid=21413348|access-date=2020-01-23|last2=Albrecht|first2=Thomas|last3=Porter|first3=David D.|archive-date=2020-04-14|archive-url=https://web.archive.org/web/20200414121324/https://www.ncbi.nlm.nih.gov/books/NBK8538/|url-status=live}}</ref> In ''subacute'' infections, symptoms take longer to develop than in acute infections but arise more quickly than those of chronic infections.
