Madagascar warned of bubonic plague epidemic

Madagascar has been warned it faces an epidemic of bubonic plague unless it slows down spread of the disease. Prisoners in the island's notoriously dirty jails are most at risk but an outbreak could easily spread to the population at large.

The Red Cross and Pasteur Institute say inmates in the island's dirty, crowded jails are particularly at risk.

The number of cases rises each October as hot humid weather attracts fleas, which transmit the disease from rats and other animals to humans.

Madagascar had 256 plague cases and 60 deaths last year, the world's highest recorded number.

Bubonic plague, known as the Black Death when it killed an estimated 25 million people in Europe during the Middle Ages, is now rare.

The International Committee of the Red Cross (ICRC) in Geneva and the Pasteur Institute have worked with local health groups in Madagascar since February 2012 on a campaign to improve prison hygiene.

"If the plague gets into prisons there could be a sort of atomic explosion of plague within the town. The prison walls will never prevent the plague from getting out and invading the rest of the town," said the institute's Christophe Rogier.

The ICRC said the 3,000 inmates of Antanimora, the main prison in the heart of the capital Antananarivo, live with a huge rat population which spreads infected fleas through food supplies, bedding and clothing.

The ICRC's Evaristo Oliviera said this could affect not only inmates and staff, but others they come into contact with.

Experts say that Africa - especially Madagascar and the Democratic Republic of Congo - accounts for more than 90% of cases worldwide.

However in August a 15-year-old herder died in Kyrgyzstan of bubonic plague - the first case in the country in 30 years - officials said

During the last 20 years, at least three countries experienced outbreaks of human plague after dormant periods of about 30-50 years, experts say.

These areas were India in 1994 and 2002, Indonesia in 1997 and Algeria in 2003.

According to the World Health Organization, the last significant outbreak of bubonic plague was in Peru in 2010 when 12 people were found to have been infected.
