Q & A

What is the primary purpose of quarantine measures?
-The primary purpose of quarantine measures is to protect society by separating healthy individuals from those who are contaminated or susceptible to contamination, in order to contain the spread of contagious diseases.
What is the origin of the term 'quarantine'?
-The term 'quarantine' originates from the Italian word 'quaranta', meaning 'forty', and was first used in the 14th century to describe the 40-day isolation period implemented as a health safety measure, especially during the time of the Black Death plague.
How did the concept of quarantine develop historically?
-The concept of quarantine developed as a response to various epidemics, starting with the isolation of lepers in leprosariums during the Middle Ages, and later evolving into a more systematic practice during the 14th and 15th centuries to combat the spread of the Black Death plague across European ports.
What was the significance of the 40-day period in quarantine?
-The 40-day period in quarantine was based on the belief, influenced by the ancient Greek physician Hippocrates, that if a disease lasted longer than 40 days, it was chronic. Thus, the 40-day isolation period aimed to determine whether individuals were cured or if they had a chronic illness rather than the plague.
How did quarantine practices evolve during the 16th century?
-During the 16th century, quarantine practices evolved to include the development of sewage systems to prevent disease spread, marking infected houses with a white cross, and burning the clothes and furniture of infected families to遏制 the spread of diseases.
What was the role of quarantine during the 19th-century cholera outbreaks?
-Quarantine was systematically used during the 19th-century cholera outbreaks to control the disease, which was an intestinal infection caused by contaminated water or food, leading to severe dehydration due to abrupt and abundant diarrhea.
Why were quarantine measures perceived as obstacles during the 19th century?
-During the 19th century, quarantine measures were increasingly seen as obstacles to human freedom and commerce due to the rise of liberalism and the Industrial Revolution, which emphasized the importance of free trade without hindrances.
What is the historical significance of Grosse Île in Quebec?
-Grosse Île in Quebec is historically significant as a quarantine station where, starting from 1832, immigrants were quarantined for 40 days to prevent the spread of diseases like cholera and typhus before they were allowed to enter Quebec.
What was the Spanish flu and why was it named so?
-The Spanish flu was a devastating influenza pandemic between 1918 and 1919 that resulted in an estimated 20 to 50 million deaths. It was named the 'Spanish flu' because, during World War I, Spain, being a neutral country, did not have wartime censorship, and its media openly reported the high incidence of the disease and deaths, unlike the media in other countries.
How effective were quarantine measures during the Spanish flu pandemic?
-Quarantine measures during the Spanish flu pandemic had some effectiveness in controlling the spread of the disease in countries with mandatory reporting. However, the disease was not initially considered serious enough to warrant such measures, and it took until September 1918 for the U.S. health department to require nationwide reporting and medical assistance for the flu.
What was Canada's response to the SARS outbreak in 2003?
-In response to the SARS outbreak in 2003, Canada quarantined nearly 100 people for each confirmed case of SARS in the country, which was considered an extreme measure compared to other countries' responses, with over 30,000 people confined in hospitals and homes in Toronto alone.
