Is Campylobacter infection serious?

Most people with a Campylobacter infection recover completely within a week, although they may shed (get rid of) Campylobacter bacteria in their stool for several weeks after recovery, which might result in person-to-person transmission. Campylobacter infection rarely results in long-term consequences. Some studies have estimated that 5–20% of people with Campylobacter infection develop irritable bowel syndrome for a limited time and 1–5% develop arthritis.

About 1 in every 1,000 reported Campylobacter illnesses leads to Guillain-Barré syndrome (GBS). GBS happens when a person』s immune system is triggered by an earlier infection, such as Campylobacter infection. GBS can lead to muscle weakness and sometimes paralysis that can last for a few weeks to several years, and often requires intensive medical care. Most people recover fully, but some have permanent nerve damage, and some have died of GBS. As many as 40% of GBS cases in the United States may be triggered by Campylobacter infection.

彎曲桿菌感染嚴重嗎？

大多數感染彎曲桿菌的患者在一周內完全康復，患者在康復後的幾周內可通過糞便排出彎曲桿菌，這可能導致人與人之間的傳播。彎曲桿菌感染很少造成長期後果。一些研究估計5-20%的彎曲桿菌感染患者在有限的時間內發展為腸易激綜合症，1-5%發展為關節炎。

約千分之一的彎曲桿菌感染導致格林-巴利綜合征（GBS）。當患者的免疫系統被早期感染（如彎曲桿菌感染）觸發時，GBS就會發生。GBS可導致肌肉無力，有時會導致持續數周至數年的癱瘓，通常需要加強醫療護理。大多數人最終完全康復，但有些患者永久性神經損傷，部分患者死於GBS。在美國，高達40%的GBS病例是由彎曲桿菌感染引發的。
