KYRGYZSTAN – Known as the Black Death, it killed 25 million people in Europe during the middle ages.
Now in Kyrgystan officials have to quarantine more than 100 people after a teenage boy died of bubonic plague.
Reports say the 15-year-old herder was bitten by an infected flea. It was the first death from the disease in the country in three decades.
The disease is rare, with the World Health Organization recording 400 cases world-wide in 2012.
Nowadays, the disease is not always deadly and can be treated with antibiotics.
Thank goodness for modern medicine.
