Avoid it like the black plague?
Oh no definitely not.
No such thing as black plague unless people just get confused, which they do.
The Black Death is the start of
the second plague pandemic, a period of about four years. Wikipedia:
"The
second plague pandemic is a major series of epidemics of the plague that started with the
Black Death, which reached mainland Europe in 1348 and killed up to a half of the population of Eurasia in the next four years. Although the plague died out in most places, it became endemic and recurred regularly. A series of major epidemics occurred in the late 17th century, and the disease recurred in some places until the 19th century."
The Plague of Justinian was the first go round. "Modern estimates suggest that half of Europe's population died as a result of this
first plague pandemic before it disappeared in the 700s."
That's a long interval between pandemics.
The third plague pandemic, surprisingly, was occurring up until 1960 when the WHO called it a wrap.
"The
third plague pandemic was a major bubonic plague pandemic that began in Yunnan, China, in 1855 during the fifth year of the Xianfeng Emperor of the Qing dynasty. This episode of bubonic plague spread to all inhabited continents, and ultimately led to more than 12 million deaths in India and China, with about 10 million killed in India alone. According to the World Health Organization, the pandemic was considered active until 1960, when worldwide casualties dropped to 200 per year."
