An outbreak of the deadly bubonic plague has tormented the former Soviet republic of Kyrgyzstan after the death of a 15-year-old boy. Three more people showed symptoms of the 'Black Death', and in total 131 came into contact with the victim. More than 800 people have been screened in the town of Bishkek, Kyrgyzstan. The disease wiped out tens of millions in 14th century Europe. It was reported that 15-year-old Temirbek Isakunov died after eating a barbecued groundhog infected with the lethal virus, yet another account suggests he became infected after being bitten by an oriental flea carried by a marmot that he reportedly prepared for food. Eastern districts of the mountainous country were in 'lockdown' last night as officials sought to prevent the plague spreading. Neighbouring Kazakhstan urged its people not to travel to the country, and introduced 'special monitoring' of those crossing the border.
