Discover the secrets of the red room of the lazaretto

By the end of the 19th century, the number of immigrants entering the country had risen dramatically. Everyone had to be vaccinated against smallpox prior to their departure from Europe. One in ten died from this highly contagious disease. The symptoms included fever, vomiting, delirium, headaches and serious skin eruptions that resulted in permanent scarring.

Despite vaccination, the disease was present in the ships arriving at the quarantine station...
According to Danish doctor Finsen, sunlight was harmful to smallpox sufferers. In 1904, a lazaretto or isolation room was thus painted red. Red skylights and light bulbs were added, thus protecting the sick from light. It was thought that this would shorten the healing time and reduce scarring. Several actions and cautions had to be considered for the duration of the treatment, which lasted about one month and a half.
