[Help during the paratyfoid-A epidemic in Kirkenes in 1943-44]

Area of Science:

• Epidemiology
• Infectious Diseases
• Public Health

Background:

• Kirkenes, Norway, a strategically important town during WWII, faced significant challenges including numerous bombing raids.
• An outbreak of paratyphoid A occurred in June 1943, exacerbated by contaminated water reservoirs linked to a nearby prisoner of war camp.

Observation:

• The epidemic escalated by November 1943, with a surge in new cases, overwhelming local medical resources.
• A significant challenge identified was the presence of convalescent carriers shedding paratyphoid bacilli, complicating disease control efforts.
• Medical support included advanced medical students and Red Cross nurses, alongside the establishment of a provisional bacteriological laboratory.

Findings:

• Mass vaccination campaigns were implemented, with the population of Sør-Varanger receiving combined typhoid, paratyphoid A, and B (TAB) vaccine, and children vaccinated against diphtheria.
• The TAB vaccine demonstrated ineffectiveness in preventing paratyphoid A infections during the outbreak.
• Official records documented 254 Norwegian cases of paratyphoid A, with an estimated true number around 300, and a single fatality due to intestinal perforation.

Implications:

• The study highlights the limitations of existing vaccines against specific strains of paratyphoid fever during large-scale outbreaks.
• Understanding the role of convalescent carriers is crucial for effective control strategies in infectious disease epidemics.
• This historical case provides valuable insights into public health responses and challenges during wartime epidemics.
