Editing Sinusitis (section)

===Acute===
[[Acute (medical)|Acute]] sinusitis is usually precipitated by an earlier [[upper respiratory tract infection]], generally of [[virus|viral]] origin, mostly caused by [[rhinovirus]]es (with RVA and RVC giving more severe infection than RVB), [[coronavirus]]es, and [[Orthomyxoviridae|influenza viruses]], others caused by [[Adenoviridae|adenoviruses]], [[human parainfluenza viruses]], [[human respiratory syncytial virus]], [[enterovirus]]es other than rhinoviruses, and [[metapneumovirus]]. If the infection is of bacterial origin, the most common three causative agents are ''[[Streptococcus pneumoniae]] (38%)'', ''[[Haemophilus influenzae]] (36%)'', and ''[[Moraxella catarrhalis]] (16%)''.<ref name="pmid31613481">{{cite journal |vauthors=DeBoer DL, Kwon E |date=2020 |title=Acute Sinusitis |journal=Statpearls |pmid=31613481}}[[File:CC-BY_icon.svg|50x50px]] Text was copied from this source, which is available under a [[ccorg:licenses/by/4.0/|Creative Commons Attribution 4.0 International License]] {{Cite web |url=https://creativecommons.org/licenses/by/4.0/ |title=Deed - Attribution 4.0 International - Creative Commons |access-date=2020-11-27 |archive-date=2017-10-16 |archive-url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |url-status=bot: unknown }}.</ref><ref name="pmid31430424">{{cite journal |vauthors=Basharat U, Aiche MM, Kim MM, Sohal M, Chang EH |title=Are rhinoviruses implicated in the pathogenesis of sinusitis and chronic rhinosinusitis exacerbations?

However, introduction of the ''H. influenzae'' type B (Hib) vaccine has dramatically decreased these infections and now non-typable ''H. influenzae'' (NTHI) is predominantly seen in clinics. Other sinusitis-causing [[bacterial]] [[pathogen]]s include ''[[Staphylococcus aureus|S. aureus]]'' and other [[streptococci]] [[species]], [[Anaerobic organism|anaerobic bacteria]] and, less commonly, [[Gram-negative]] bacteria. Viral sinusitis typically lasts for 7 to 10 days.<ref name="pmid18206715" />

[[Acute (medical)|Acute]] episodes of sinusitis can also result from [[fungus|fungal]] invasion. These infections are typically seen in people with [[diabetes]] or other [[immunodeficiency|immune deficiencies]] (such as [[AIDS]] or [[Organ transplant|transplant]] on immunosuppressive antirejection medications) and can be life-threatening. In type I diabetics, ketoacidosis can be associated with sinusitis due to [[mucormycosis]].<ref>{{EMedicine|article|222551|Mucormycosis}}</ref>
