“…Such a high incidence of cases in monsoon might be because of high chance of infection in low socioeconomic class. Similar types of observation 32.39% in monsoon and 23.59% in summer were revealed by Mathew et al from south India [19]. But in contrast to our result, studies from north India Sharma G et al [20] (Rohtak) reported peak seasonal clustering in summer followed by spring season while Sharma A et al [18] (Chandigarh) observed C. Jejuni positive cases mainly in winter season and was often associated with axonal variety of GBS.…”

“…In our study, month wise peaks were seen in month June to August (46%) and nearly equal cases in month March to May and October to December but no case observed in month January. Study done by Mathew et al observed month wise peak in June to September and second peak in November to January [19]. Similarly Wu et al from China reported higher incidence of cases in July and August and was significantly higher in children compared to adults [12].…”

“…reported results of a cohort study in the United States [24] and found that the GBS incidence rates estimated from emergency and in-patient visits were 15% higher in winter and spring than in summer and fall. Other studies documenting seasonal variation in GBS attributed this to higher rates of infection in certain seasons [7,12,18,25] . Demyelinating GBS, axonal GBS, and Miller Fisher syndrome are subtypes of GBS.…”

Background: Guillain-Barré syndrome (GBS) is a potentially life-threatening disease that typically occurs after a preceding infectious disease. An accurate estimation of GBS incidence would be useful for investigating the potential causal relationships between risk factors and GBS. Here we described the nationwide incidence of GBS in Taiwan. Methods: The cases of GBS were obtained from all admission records of the National Health Insurance Research Database. We identified all of the first-admitted GBS patients by a code of ICD-9-CM 357.0 presented at the discharge diagnoses in admission records between 1997 and 2011. Calendar year, age, and sex-specific incidence, and seasonal variation were estimated. Results: A total of 5,998 patients were identified. The male-to-female rate ratio was 1.54. The crude incidence rate was 1.65 per 100,000 person-years. The incidence of GBS was lowest in people aged less than 20 and increased with age, especially in people older than 50 years. In spring, the incidence was 10% higher than in other seasons. Conclusions: The overall incidence is in line with previous large-scale studies. A significant higher rate in spring is also shown. The potential reasons for the seasonality and higher incidence among older patients should be further investigated.

“…On the other hand, some studies have noted seasonal winter patterns for GBS incidence. [61] A study that examined the seasonal pattern of GBS for the year 2009 reported that an increase in vaccination coverage from 19.7% to 35.5% resulted in no similar increase in GBS cases. [62] Some other studies revealed that influenza cases increased during 2004-2005 exactly overlapping with the wave of hospitalization due to GBS during the same period.…”

Guillain–Barré syndrome (GBS) is an inflammatory disorder and an acute immune-mediated demyelinating neuropathy that causes reduced signal transmissions, progressive muscle weakness, and paralysis. The etiology of the syndrome still remains controversial and uncertain. GBS can be initiated and triggered by respiratory tract infections such as influenza, and intestinal infections such as Campylobacter jejuni. In addition, there is considerable evidence suggesting links between influenza vaccination and GBS. As reported previously, the incidence of GBS in individuals receiving swine flu vaccine was about one to two cases per million. Despite the influenza vaccine efficacy, its association with an immune-mediated demyelinating process can be challenging as millions of people get vaccinated every year. In this review we will discuss the association between influenza infection and vaccination with GBS by focusing on the possible immunopathological mechanisms.
